| openstack | Meeting started Wed Jan 31 01:06:00 2018 UTC and is due to finish in 60 minutes. The chair is zhiyuan. Information about MeetBot at http://wiki.debian.org/MeetBot. | 01:06 |

| zhiyuan | #topic new-l3-model | 01:06 |
| *** openstack changes topic to "new-l3-model (Meeting topic: tricircle)" | 01:06 | |
| zhiyuan | first I would like to discuss the new l3 modle | 01:06 |
| *** donghao has joined #openstack-meeting | 01:07 | |
| zhiyuan | as we know, currently a router only support one external gateway | 01:07 |
| zhiyuan | but in our new model, we need to associate one router with more than one external networks | 01:07 |
| zhiyuan | Yipei, is that correct? that's our current problem | 01:08 |
| *** rcernin has joined #openstack-meeting | 01:09 | |
| Yipei | yes, actually only the gateway of bridge net is set to the router. but to add the external network to the router, the gateway port is specified as a hint | 01:10 |
| *** donghao has quit IRC | 01:12 | |
| Yipei | so maybe we need to find another way to add the external network to the non local router | 01:12 |
| zhiyuan | in your graph, the actual topology is that local routers and non-local routers are all connected to the bridge network, but since bridge network is not exposed to users, we can only expose one router to users | 01:13 |
| zhiyuan | and we automatically create the local and non-local routers | 01:13 |
| *** Neptu_ has quit IRC | 01:13 | |
| *** slaweq has joined #openstack-meeting | 01:13 | |
| Yipei | i think the non local router can be created by users | 01:14 |
| *** felipemonteiro__ has quit IRC | 01:14 | |
| zhiyuan | if so, how to trigger tricircle to attach the local router to bridge network? | 01:15 |
| *** Neptu has joined #openstack-meeting | 01:16 | |
| *** wanghao_ has quit IRC | 01:16 | |
| zhiyuan | when non local router is not created | 01:16 |

| *** zhujintao has joined #openstack-meeting | 01:17 | |
| *** jamesmcarthur has quit IRC | 01:17 | |
| Yipei | oh, i see. i was oblivious to the case | 01:17 |
| *** bobmel has joined #openstack-meeting | 01:17 | |
| *** slaweq has quit IRC | 01:18 | |
| zhiyuan | yeah, in the new model, both EW and NS traffic need to go through the non-local router | 01:18 |
| *** ricolin has joined #openstack-meeting | 01:19 | |
| *** gongysh has joined #openstack-meeting | 01:19 | |
| zhiyuan | so I suggest to expose only one router | 01:19 |
| *** pzchen has joined #openstack-meeting | 01:20 | |
| *** yangyapeng has joined #openstack-meeting | 01:21 | |
| *** ricolin has quit IRC | 01:21 | |
| Yipei | you mean only exposing the non local router, and interfaces of networks are added to the router, the gateway of the bridge net is set to the router | 01:23 |
| Yipei | the local routers are transparent to users | 01:24 |
| zhiyuan | tenant networks and external networks are all attached to the exposed router | 01:24 |
| Yipei | so the non local router must be created first | 01:24 |
| zhiyuan | no need to distinguish local and non-local | 01:25 |
| Yipei | ok, i see | 01:25 |
| zhiyuan | "tenant networks and external networks are all attached to the exposed router", this is in the user perspective | 01:26 |
| Yipei | ok, i see | 01:26 |
| *** jamesmcarthur has joined #openstack-meeting | 01:26 | |
| *** liyi has joined #openstack-meeting | 01:27 | |
| zhiyuan | however, one router can only be attached to one external network, so we need to find a way to associate more than one external network info to one "external network instance" | 01:28 |
| *** HeOS has joined #openstack-meeting | 01:29 | |
| zhiyuan | there are two ways. One is using subnet, one network can have more than one subnets, the other is using "routed network", one routed network can have more than one segments | 01:29 |
| *** diablo_rojo has quit IRC | 01:30 | |
| *** markvoelker has joined #openstack-meeting | 01:30 | |
| Yipei | ok, i think i need to investigate the two solutions | 01:31 |
| zhiyuan | I prefer the routed network way, network info can be saved in the segment of routed network. But we need to see how to map the segment info to specific region | 01:33 |
| *** zhongjun has joined #openstack-meeting | 01:34 | |
| Yipei | ok, i will do some research on the routed network solution and update the spec | 01:35 |
| *** caisan_ has joined #openstack-meeting | 01:35 | |
| zhiyuan | fine, you can check if the data model of routed network has some space for us to save the region info | 01:36 |
| zhiyuan | next let's move to the resource deleting patch | 01:36 |
| zhiyuan | #topic reliable resource deletion | 01:36 |
| *** openstack changes topic to "reliable resource deletion (Meeting topic: tricircle)" | 01:36 | |
| zhiyuan | I check the log and find the reason for the error | 01:37 |
| *** mriedem_afk is now known as mriedem | 01:37 | |
| song | why? | 01:37 |
| song | I have checked use neutron 404 | 01:37 |
| song | but last day also failed | 01:37 |
| *** caisan has quit IRC | 01:37 | |
| zhiyuan | the flow is that: user delete network -> central neutron mark "in-delete", then call local neutron to delete -> local neutron "get-network" before delete network -> central neutron receive "get-network" request from local neutron and return 404(since "in-delete" is mark) -> local neutron raise exception | 01:39 |
| song | yes, i think my code is so. | 01:41 |
| zhiyuan | oh, this analysis is based on your code submitted, after you change the exception to neutron exception, the local neutron still raise exception? | 01:42 |
| song | yes | 01:42 |
| song | I have send the error last night in wechart. | 01:43 |
| zhiyuan | so it doesn't ignore the 404 response and return directly in "delete-network" | 01:43 |
| song | it is raised in get network. | 01:44 |
| song | when request come from local. | 01:44 |
| xuzhuang | what's the exception raised in local neutron? | 01:46 |
| zhiyuan | it's fine for get-network to raise not-found exception, this exception will be wrapped as a 404 response | 01:47 |
| song | in the neutron client client.py line 92 exception_handle_v2.0 | 01:47 |
| song | I submit a new path today use the neuron exception so you can see the log. | 01:48 |
| *** cdub has joined #openstack-meeting | 01:48 | |
| *** fnaval has joined #openstack-meeting | 01:50 | |
| *** haint_ has joined #openstack-meeting | 01:51 | |
| zhiyuan | ok, let's check the log after that. | 01:53 |
| *** salv-orlando has joined #openstack-meeting | 01:53 | |
| xuzhuang | when I run the unit test of delete_sg, raise DBNonExistentTable: (sqlite3.OperationalError) no such table: securitygroupportbindings. | 01:53 |
| xuzhuang | I think it should configure the table of securitygroupportbindings in unit test, but haven't worked. | 01:53 |
| *** Tom-Tom has joined #openstack-meeting | 01:53 | |
| song | to xuzhuang have you rerun stack.sh | 01:54 |
| song | if you change database table you need rerun it | 01:54 |
| *** kiennt26 has joined #openstack-meeting | 01:54 | |
| xuzhuang | unit test also need rerun stack.sh? | 01:55 |
| *** haint93 has quit IRC | 01:55 | |
| *** fnaval has quit IRC | 01:55 | |
| zhiyuan | neutron db operation in unit test is simulated in tricircle/tests/unit/utils.py | 01:55 |
| song | I mean if you change the database table after run devstack. | 01:56 |
| zhiyuan | song, xuzhuang's problem is that the needed neutron table in not created in unit test | 01:56 |
| xuzhuang | oh, i haven't changed table | 01:57 |
| song | oh i miss understand it sorry. | 01:57 |
| *** wanghao has quit IRC | 01:57 | |
| *** salv-orlando has quit IRC | 01:57 | |
| zhiyuan | after you register the table in tests/unit/utils.py, what error occurs? | 01:58 |
| *** wanghao has joined #openstack-meeting | 01:58 | |
| xuzhuang | you mean configed portbinds in _resource_list? I have try this solution, but it haven't worked. | 01:59 |
| zhiyuan | so I am asking the error | 01:59 |
| zhiyuan | you may also modify " def add(self, model_obj):" | 01:59 |
| xuzhuang | ok, i will have a tryp | 02:00 |
| zhiyuan | to save the related resource in self.store_map | 02:00 |
| *** cdub has quit IRC | 02:00 | |
| xuzhuang | ok | 02:01 |
| xuzhuang | I have learned about the mapping of default security group between central and local. But I haven't known | 02:01 |
| xuzhuang | the relation ship of normal security group between central and local. There is no create_security_group in tricircle, | 02:01 |
| xuzhuang | should i add this function? | 02:01 |
| zhiyuan | tests/unit/utils.py mocks all the DB operation function for neutron resource, so if you find some table missing, or some resource not found, you can check this file | 02:01 |
| xuzhuang | ok, Got it | 02:02 |
| zhiyuan | network/security_groups.py already inherit securitygroups_db.SecurityGroupDbMixin, no new definition means that the base function is used | 02:03 |
| *** gongysh has quit IRC | 02:03 | |
| zhiyuan | you can create new SEG via tricircle | 02:03 |
| xuzhuang | ok, when deleting security group should i delete the rules belonged this sg firstly? | 02:04 |
| zhiyuan | for this, you can check if deleting a SEG will delete all the rules under it in Neutron first | 02:05 |
| zhiyuan | if so, you just delete the SEG | 02:06 |
| xuzhuang | ok, Got it | 02:06 |
| zhiyuan | so much for today, thanks for attending | 02:07 |

| daveholland | hi all | 11:02 |
| *** ijw has joined #openstack-meeting | 11:02 | |
| b1airo | apologies if i'm a little slow - only 10pm here but i'm particularly shattered this evening for some reason | 11:02 |
| b1airo | hi daveholland | 11:02 |
| oneswig | There's about a week to go until the summit CFP closes, HPC/GPU/AI topics please! | 11:02 |
| *** Tom-Tom has quit IRC | 11:03 | |
| oneswig | no worries b1airo | 11:03 |
| * johnthetubaguy hides at the back of the room | 11:03 | |
| armstrong | @oneswig: meetings now are only on Wednesdays? | 11:03 |
| oneswig | Quite an interesting subject for a track and I'm hoping for some good use cases | 11:03 |
| b1airo | you're an expert now johnthetubaguy! | 11:03 |
| oneswig | armstrong: no, Tuesday 2100UTC on alternate weeks | 11:03 |
| johnthetubaguy | b1airo: heh | 11:04 |
| * ildikov lurks behind johnthetubaguy :) | 11:04 | |
| oneswig | Hi johnthetubaguy, we'll get round to the nova bits shortly | 11:04 |
| oneswig | Quiet at the back there please! | 11:04 |
| b1airo | anyone know how the submissions are looking? | 11:04 |
| oneswig | No, don't think that comes out until the deadline closes. | 11:05 |
| oneswig | Was thinking of writing around to a few orgs that might be interested to make sure they are aware | 11:05 |
| b1airo | i heard from a few people they liked the change up of the tracks, but don't think any of my colleagues have actually submitted anything | 11:05 |
| ildikov | oneswig: +1 | 11:05 |
| b1airo | yeah good idea | 11:05 |
| oneswig | b1airo: you've got to put something meaty in on GPUs, haven't you? | 11:06 |
| b1airo | actually i don't think it has gone around on the OzStackers list yet... | 11:06 |
| *** andreas_s has quit IRC | 11:06 | |
| oneswig | Take care of matters b1airo | 11:06 |
| oneswig | In general can we try to circulate awareness of the HPC/GPU/AI track and the 8th Feb deadline | 11:07 |
| oneswig | that'd be great | 11:07 |
| *** andreas_s has joined #openstack-meeting | 11:07 | |
| b1airo | is there a thumbs up ascii symbol? | 11:07 |
| *** yankcrime has joined #openstack-meeting | 11:07 | |
| oneswig | This IRC, so quaint, like vintage motoring :-) | 11:08 |
| oneswig | Let's move on | 11:08 |
| oneswig | #topic Dublin PTG | 11:08 |
| *** openstack changes topic to "Dublin PTG (Meeting topic: scientific-sig)" | 11:08 | |
| oneswig | Short notice on this - if you're going and don't have a ticket yet, buy it right now. | 11:09 |
| *** alexchadin has quit IRC | 11:09 | |
| ildikov | price increases on Thursday | 11:09 |
| ildikov | so hurry up! :) | 11:09 |
| b1airo | are you scalping oneswig? | 11:09 |
| oneswig | It jumpstarted me into action... our away team's all sorted (finally). | 11:09 |
| oneswig | b1airo: ha, to you, sir, special price | 11:10 |
| priteau | It says "57 remaining" right now | 11:10 |
| priteau | Is there also a quantity limit on the $100 tickets? | 11:10 |
| oneswig | We've covered content already, but are open to more items | 11:10 |
| oneswig | priteau: was 80 yesterday, I believe | 11:11 |
| *** andreas_s has quit IRC | 11:11 | |
| *** jamesmcarthur has joined #openstack-meeting | 11:12 | |
| johnthetubaguy | thats probably the overall limit I think | 11:12 |
| johnthetubaguy | size is small to keep the costs down I believe | 11:12 |
| oneswig | I think so, don't think more tickets will be appearing - unless anyone knows otherwise | 11:12 |
| oneswig | OK, one more event to cover | 11:13 |
| oneswig | #topic HPCAC Lugano | 11:13 |
| *** openstack changes topic to "HPCAC Lugano (Meeting topic: scientific-sig)" | 11:13 | |
| oneswig | As I understand it, b1airo gave a barnstorming performance at the last one in Perth, right Blair? | 11:13 |
| oneswig | #link conference page https://www.cscs.ch/publications/press-releases/swiss-hpc-advisory-council-conference-2018-hpcxxl-user-group/ | 11:13 |
| oneswig | OpenStack's now front and central in this conference. | 11:14 |
| b1airo | i really enjoyed it... | 11:14 |
| oneswig | I went last year and thought it was good. zioproto came along and gave a good talk | 11:14 |
| oneswig | And Lugano, what's not to like about that | 11:15 |
| b1airo | true dat | 11:15 |
| oneswig | 9th-12th April if you're interested, perhaps I'll see you there (haven't completely decided yet) | 11:16 |
| b1airo | i was expecting an invite from Cindy for that, they probably decided you were better oneswig! | 11:16 |
| belmoreira | oneswig great to know | 11:16 |
| *** jamesmcarthur has quit IRC | 11:16 | |

| oneswig | b1airo: I had a mail from Hussein about it | 11:17 |
| *** andreas_s has joined #openstack-meeting | 11:17 | |

| *** sinese has quit IRC | 11:17 | |
| oneswig | #topic preemptible instances in OpenStack | 11:18 |
| *** openstack changes topic to "preemptible instances in OpenStack (Meeting topic: scientific-sig)" | 11:18 | |
| oneswig | today's main event! | 11:18 |
| oneswig | belmoreira: how's your reaper project developing? can you describe it? | 11:19 |
| belmoreira | I will give the floor to ttsiouts | 11:19 |
| ttsiouts | belmoreira: thanks! | 11:19 |
| ttsiouts | Currently, the operators use project quotas for ensuring the fair sharing of their infrastructure. | 11:20 |
| *** rfolco|off is now known as rfolco | 11:20 | |
| ttsiouts | The problem with this, is that quotas pose as hard limits. | 11:20 |
| ttsiouts | This leads to actually dedicating resources for workloads even if the resources are not used all the time. | 11:20 |
| ttsiouts | Which in turn leads to lower cloud utilization | 11:20 |
| ttsiouts | So there are idle and unused resources when at the same time, the users ask for more resources. | 11:21 |
| *** donghao has quit IRC | 11:21 | |
| ttsiouts | The concept of Preemptible Instances tries to address to this problem. | 11:21 |
| *** mdbooth has quit IRC | 11:21 | |
| ttsiouts | This type of servers can be spawned on top of the project's quota, making use of the idling resources. | 11:21 |
| * johnthetubaguy whoops in agreement | 11:21 | |

| oneswig | ttsiouts: how often does the CERN cloud run out of hosts? | 11:21 |
| *** andreas_s has quit IRC | 11:22 | |
| belmoreira | we manage quotas and expectations to not happen | 11:22 |
| ttsiouts | Here in Cern we have compute intensive workloads such as batch processing. | 11:23 |
| ttsiouts | For those, currently we use projects with dedicated quota. | 11:23 |
| *** mdbooth has joined #openstack-meeting | 11:23 | |
| ttsiouts | so we are committing big chunks of the Cern's cloud infra to these workloads even when the resources are not actually used, which leads to lower cloud utilization. | 11:24 |
| *** wanghao has quit IRC | 11:24 | |
| b1airo | "dedicated" means that <committed quota> == <available resource> ? | 11:24 |
| johnthetubaguy | I like to think of this as slicing your cloud, like pizza, using quota. you don't want the unused bits going to waste | 11:24 |
| strigazi | b1airo it depends on the user | 11:24 |
| belmoreira | b1airo for compute processing yes | 11:25 |
| ttsiouts | johnthetubaguy: yes | 11:25 |
| b1airo | got it - i understand this might not be true for general purpose instances | 11:25 |
| *** jamesmcarthur has joined #openstack-meeting | 11:25 | |
| belmoreira | b1airo correct | 11:25 |
| b1airo | i assume you control this by segmenting the offerings across AZs or something? | 11:25 |
| johnthetubaguy | so some enterprises hit issues when departments co-fund a cloud, but want to keep the bits they paid for | 11:26 |
| belmoreira | compute is segmented through cells | 11:26 |
| *** kopecmartin has joined #openstack-meeting | 11:26 | |
| b1airo | johnthetubaguy: yeah we have that problem too | 11:26 |
| b1airo | please continue ttsiouts | 11:27 |
| *** andreas_s has joined #openstack-meeting | 11:27 | |
| belmoreira | johnthetubaguy yeah, that is also our main issue | 11:27 |
| ttsiouts | So currently we are prototyping a service to orchestrate the preemptible instances. | 11:27 |
| ttsiouts | The "reaper" service! | 11:27 |
| *** martial_ has joined #openstack-meeting | 11:27 | |
| ttsiouts | As proposed by the Nova team in the latest PTG, the service is external to Nova. | 11:27 |
| ttsiouts | The purpose of this is to help us identify what changes are needed in the Nova code base, if any, in order to make the preemptible instances work. | 11:28 |
| ttsiouts | There are various things that have to be addressed here. | 11:28 |
| ttsiouts | There is the need to tag the preemptible servers with a preepmptible property at creation time. | 11:29 |
| *** ijw has quit IRC | 11:29 | |
| ttsiouts | And the property should be immutable. | 11:29 |
| armstrong | @ttsiouts: does CERN uses OpenStack cloud? | 11:29 |
| *** alexchadin has joined #openstack-meeting | 11:29 | |
| *** jamesmcarthur has quit IRC | 11:29 | |
| belmoreira | armstrong yes | 11:30 |
| ttsiouts | armstrong: yes! Openstack is a big thing for Cern. | 11:30 |
| johnthetubaguy | The way I hope we talk about this at the PTG to Nova folks is: so we tried everything external to Nova, these few things suck when we do that, so we need to work out how to address those things | 11:30 |
| ttsiouts | johnthetubaguy: +1 | 11:31 |
| oneswig | ttsiouts: johnthetubaguy: can we go over what works and what doesn't? | 11:31 |
| johnthetubaguy | that preemptable property is a good point | 11:31 |
| oneswig | I believe it only partially protects against running out of capacity, right? | 11:31 |
| *** martial_ has quit IRC | 11:32 | |
| *** alexchadin has quit IRC | 11:32 | |
| johnthetubaguy | its more about maximizing utilization, I believe | 11:32 |
| *** martial_ has joined #openstack-meeting | 11:33 | |
| johnthetubaguy | i.e. only stop being able to build servers when you really have no more room | 11:33 |
| b1airo | what happens when an on-demand request comes in for capacity that is currently filled by preemptible instances? | 11:34 |
| daveholland | how does the scheduler connect with the reaper? does the reaper get triggered when the scheduler thinks it can't find a valid host? (do point me at docs if this is already covered somewhere) | 11:34 |
| oneswig | johnthetubaguy: but with an external service, is there an issue that preemptible instances might not be harvested in time when availability requires it? | 11:34 |
| johnthetubaguy | yes, we have the scheduler no valid host triggering the reaper | 11:34 |
| johnthetubaguy | ttsiouts: ? | 11:34 |
| johnthetubaguy | did I just make that up :) | 11:35 |
| ttsiouts | The service is triggered by the scheduler when the placement returns no valid hosts for the requested resources during a boot requested. | 11:35 |
| * johnthetubaguy is about to move location, may get disconnected | 11:35 | |
| daveholland | so the expectation is that the reaper reaps fast enough to be within the overall scheduler timeout? | 11:35 |
| oneswig | ttsiouts: From your tests, do higher-level services like Heat cover for the occasional No Valid Hosts, and hide it from the user? | 11:36 |
| ttsiouts | daveholland: Hopefully yes | 11:36 |
| *** andreas_s has quit IRC | 11:36 | |
| ttsiouts | oneswig: Actually we try to avoid the NoValidHosts exception | 11:36 |
| *** jamesmcarthur has joined #openstack-meeting | 11:36 | |
| ttsiouts | We trigger the reaper as soon as the placement return no allocation candidates | 11:37 |
| belmoreira | oneswig this should be hidden for the user | 11:37 |
| oneswig | ah, so the failure never makes it back to the API request? | 11:37 |
| ttsiouts | oneswig: yes | 11:38 |
| oneswig | Are you able to signal preemptible instances before they get terminated, or is there simply no time for a grace period? | 11:38 |
| ttsiouts | If the reaper fails, then we have the NoValidHosts exception raised | 11:38 |
| johnthetubaguy | yeah, this all happens after the create server API has returned | 11:39 |
| *** markvoelker has joined #openstack-meeting | 11:39 | |
| johnthetubaguy | but server will go to error if you can't find room | 11:39 |
| oneswig | johnthetubaguy: ah, of course, thanks | 11:39 |
| priteau | ttsiouts: And that's done without any modification to the nova scheduler code? | 11:39 |
| johnthetubaguy | these are the changes we want to make to nova | 11:39 |
| b1airo | so the timeout (or not) and ability to signal the p-instance should all be configurable i guess (eventually anyway) | 11:39 |
| *** alexchadin has joined #openstack-meeting | 11:39 | |
| johnthetubaguy | I think this is in the conductor rather than the scheduler, at least ideally, but thats a technicallity | 11:40 |
| ttsiouts | priteau: the only modification we've done is the triggering of the reaper | 11:40 |
| ttsiouts | priteau: with the same request that is placed to placement | 11:40 |
| priteau | I would love to see the code if you have it public somewhere | 11:40 |
| johnthetubaguy | me too, would love to review where we are | 11:41 |
| *** tpsilva has joined #openstack-meeting | 11:41 | |
| *** jamesmcarthur has quit IRC | 11:41 | |
| ttsiouts | priteau, johnthetubaguy: this is pretty early development stage | 11:41 |
| johnthetubaguy | thats all good, just a github branch is fine | 11:41 |
| belmoreira | ttsiouts isn't our repo public? | 11:41 |
| oneswig | ttsiouts: are there complexities introduced if (eg) the reaper or the scheduler that invokes it were to die at this point? | 11:41 |
| *** andreas_s has joined #openstack-meeting | 11:42 | |
| ttsiouts | belmoreira: there are several things to be done.. | 11:42 |
| belmoreira | yeah, I know. But I though we made it public few time ago | 11:43 |
| *** thiagomanel has joined #openstack-meeting | 11:43 | |
| ttsiouts | I guess we can make it public.. | 11:43 |
| oneswig | ttsiouts: belmoreira: are there assumptions about cern's use case or is it already generalised | 11:43 |
| *** alexchadin has quit IRC | 11:44 | |
| oneswig | It seems to have huge potential for many use cases. | 11:44 |
| johnthetubaguy | where I can see this getting tricky is deciding who gets deleted by the reaper | 11:44 |
| belmoreira | oneswig initially we would like to run p-instances in dedicated projects | 11:45 |
| *** Fubica has joined #openstack-meeting | 11:45 | |
| *** jamesmcarthur has joined #openstack-meeting | 11:45 | |
| ttsiouts | oneswig: For this prototype the flavors used for spawning this kind of servers are tagged as preemptible. | 11:45 |
| johnthetubaguy | belmoreira: good call out, that's a simplification we can work through later | 11:45 |
| b1airo | belmoreira: we have the same desire - would meet 80% of our need | 11:45 |
| daveholland | I like the flavour/flavor approach, that's easy for users to understand | 11:45 |
| johnthetubaguy | b1airo: interesting | 11:46 |
| belmoreira | johnthetubaguy just to mentioned that our usecase is not that generic (at least initially) | 11:46 |
| b1airo | we even started spec'ing out a similar project, albeit without the integration and just having a pool of resource dedicated for temporary instances | 11:46 |
| johnthetubaguy | daveholland: +1 (although its a shame you create so many flavors!) | 11:46 |
| johnthetubaguy | belmoreira: +1 although its more general that it first seems | 11:46 |
| priteau | johnthetubaguy: It would be nice to have a configurable reaper decision engine, like Nova scheduler weighters | 11:46 |
| johnthetubaguy | priteau: I am tempted to go simpler than that, but +1 on the customizable part of that | 11:47 |
| ttsiouts | priteau: Actually we are experimenting with two strategies for selecting servers. | 11:47 |
| *** thiagomanel_ has joined #openstack-meeting | 11:47 | |
| oneswig | Has this got the attention of the public cloud folks yet? | 11:47 |
| *** thiagomanel has quit IRC | 11:47 | |
| johnthetubaguy | ttsiouts: I am curious where you settled with that | 11:47 |
| ttsiouts | The first one maps servers to hosts. | 11:48 |
| ttsiouts | Then it selects a host that could provide the requested resources. | 11:48 |
| johnthetubaguy | oneswig: good point, worth reaching out to that SIG (someone must do reserved instances and live-migrates) | 11:48 |
| belmoreira | daveholland for our use case we don't see a need for many flavors. We think a small/generic flavor will be enough | 11:48 |
| martial_ | oneswig: the PTG is a good option to do just that | 11:48 |
| ttsiouts | and as a last step finds a combination of preemptible servers that will be killed to free up the resources | 11:48 |
| *** yamamoto_ has quit IRC | 11:48 | |
| ttsiouts | The second strategy tries to eliminate the idling resources. | 11:48 |
| oneswig | Hi martial_ - morning | 11:48 |
| oneswig | #chair martial_ | 11:48 |
| openstack | Current chairs: b1airo martial_ oneswig | 11:48 |
| ttsiouts | So it select the minimum of the existing preemptible resources that in combination with the already idle resources of the selected host, provide the requested resources. | 11:48 |
| johnthetubaguy | martial_: often don't get many SIG folks at the PTG, at least it feels that way most times | 11:48 |
| martial_ | (thanks Stig, been listening) | 11:49 |
| *** alexchadin has joined #openstack-meeting | 11:49 | |
| *** jamesmcarthur has quit IRC | 11:49 | |
| martial_ | johnthetubaguy: Tobias (part of the Public Cloud WG) reached out, so I know he is going to be there | 11:49 |
| oneswig | johnthetubaguy: true, I don't know if they've booked time at the PTG | 11:49 |
| johnthetubaguy | martial_: ah, excellent | 11:49 |
| oneswig | ah good | 11:50 |
| daveholland | we have ~20 flavours (some of those are to distinguish root-on-hypervisor from root-on-ceph) so a few more won't hurt. I'd be wary of doubling that for pre-emptible vs not-pre-empt though | 11:50 |
| * johnthetubaguy hopes we get to flavor decomposition eventually! | 11:50 | |
| belmoreira | johnthetubaguy ahaha :) | 11:51 |
| oneswig | In an Ironic use case (if indeed there is one), processes like node cleaning could make this a seriously lengthy build time | 11:51 |

| b1airo | did you ever use EC2 back in the day oneswig - sometimes took them over 10 mins just to build a Xen VM! | 11:51 |
| oneswig | b1airo: alas no... | 11:52 |
| *** alexchadin has quit IRC | 11:52 | |
| b1airo | everyone is getting exceptionally spoiled by on-demand computing. kids these days... | 11:52 |
| johnthetubaguy | heh | 11:52 |
| oneswig | ttsiouts: There's loads of interest here. How can we get involved? | 11:52 |
| oneswig | Will you announce when the git repo is ready? | 11:53 |
| johnthetubaguy | oneswig: its a good point, you may have to wait! | 11:53 |
| *** salv-orlando has joined #openstack-meeting | 11:53 | |
| johnthetubaguy | I like the idea of dropping a mail to the ML for public and scientific SIG, linking to the prototype code | 11:53 |
| oneswig | me too | 11:53 |
| *** alexchadin has joined #openstack-meeting | 11:53 | |
| b1airo | this all started with someone sticking web-services in-front of batch-queued clusters (i.e., The Grid), feels like we're about to come full-circle ;-) | 11:54 |
| johnthetubaguy | b1airo: +1 bite our tail or something | 11:54 |
| oneswig | There's a good deal of that! | 11:54 |
| belmoreira | oneswig never though about an ironic usecase... interesting. But that seems more tricky | 11:54 |
| *** fnaval has quit IRC | 11:55 | |
| oneswig | belmoreira: signalling the instance on reaping might be harder, there's an nmi that can be injected but who knows what effect it would have | 11:55 |
| b1airo | ttsiouts: i like the idea of first preempting instances that are idling, i think that fits the science-cloud use-case, public-cloud would want other things i guess (e.g. billing/bidding tie ins) | 11:55 |
| *** jamesmcarthur has joined #openstack-meeting | 11:56 | |
| *** alexchadin has quit IRC | 11:56 | |
| oneswig | b1airo: you're right, a good design would provide a nice separation of policy and mechanism | 11:56 |
| johnthetubaguy | most of the extra things seem to boil down to priority of different spot instances | 11:56 |
| oneswig | We are nearly out of time. Any more on this? | 11:57 |
| johnthetubaguy | not saying that makes it easy! | 11:57 |
| *** watanabe_isao has joined #openstack-meeting | 11:57 | |
| ttsiouts | I can add the link to it in the meeting agenda after the meeting | 11:57 |
| b1airo | johnthetubaguy: got it - you'll have it ready for Rocky ;-) | 11:57 |
| johnthetubaguy | ttsiouts: belmoreira: are we good sending that ML message? | 11:57 |
| *** salv-orlando has quit IRC | 11:57 | |
| oneswig | ok - thanks ttsiouts | 11:57 |
| johnthetubaguy | ah, cool | 11:58 |

| oneswig | b1airo: you may be on your own there :-) | 12:00 |
| b1airo | i guessed as much - for some reason the Windows end doesn't auto-scale the tcp window | 12:00 |

| bnemec | mugsie: I'm a bit stuck on the worker container, but I've gotten distracted by some other stuff this week so I haven't had a chance to really dig into it either. | 14:08 |
| mugsie | That does happen, doesn't it :) | 14:08 |
| bnemec | It's still a TripleO thing though, not any problems with Designate AFAICT. | 14:08 |
| bnemec | Yeah. :-) | 14:08 |
| mugsie | If you need any help debuging let me know | 14:09 |

| *** openstack changes topic to "roll call (Meeting topic: fog-edge-massively-distributed-clouds)" | 15:02 | |
| kgiusti | o/ | 15:02 |
| ad_ri3n_1 | and actually I'm also travelling so the meeting should be rather short ;) | 15:02 |
| ansmith | o/ | 15:02 |
| ad_ri3n_1 | Hi kgiusti | 15:02 |
| kgiusti | hello everyone! | 15:02 |
| ad_ri3n_1 | hi ansmith | 15:02 |
| ad_ri3n_1 | msimonin has some contraints and we (Alex me,…) are travelling | 15:03 |
| ad_ri3n_1 | So I don't think we will have a long meeting today ;) | 15:03 |
| ad_ri3n_1 | anyone else? | 15:03 |
| ad_ri3n_1 | #info agenda | 15:03 |
| ad_ri3n_1 | #link https://etherpad.openstack.org/p/massivfbely_distributed_ircmeetings_2018 (line 140) | 15:04 |
| *** samP has joined #openstack-meeting | 15:04 | |
| ad_ri3n_1 | So maybe the most important one. We started a gap analysis of the different openstack deployment scenarios according to some features end-users/developpers of edge computing infrastructures may expect | 15:05 |
| ad_ri3n_1 | I will come back later as I would like to ask you to go and comment it. | 15:05 |
| ad_ri3n_1 | Regarding the edge sessions that are done simultaneously, the meeting has been cancelled yesterday | 15:05 |
| ad_ri3n_1 | so nothing new | 15:05 |
| *** msimonin has joined #openstack-meeting | 15:06 | |
| ad_ri3n_1 | finally regarding the presentations I listed the ones I'm aware about it | 15:06 |
| ad_ri3n_1 | I'm not sure there will be other ones | 15:07 |
| ad_ri3n_1 | if you are aware of others please can you add them. | 15:07 |
| ad_ri3n_1 | kgiusti: ansmith maybe some edge presentations from redhat have been already planned to be submitted ? | 15:07 |
| kgiusti | I'm not specifically aware of any, but we'll ping the right people - ansmith? | 15:08 |
| ansmith | I am not aware but will look into it | 15:08 |
| ad_ri3n_1 | ok thanks | 15:08 |
| ad_ri3n_1 | any news from your side ? | 15:09 |

| *** openstack changes topic to "ongoing-action-amqp (Meeting topic: fog-edge-massively-distributed-clouds)" | 15:09 | |
| ad_ri3n_1 | kgiusti: I saw you put a lot of text. | 15:09 |
| ad_ri3n_1 | please | 15:10 |
| kgiusti | Yeah, spent some time working on a plan for dragonflow integration | 15:10 |
| ad_ri3n_1 | can you give us an overwiew? | 15:10 |
| kgiusti | Yes - there's interest in adding oslo.messaging support for dragonflow project | 15:10 |
| oanson | Hi. Sorry I'm late. I thought this was next week. | 15:10 |
| kgiusti | url: https://wiki.openstack.org/wiki/Dragonflow | 15:10 |
| ad_ri3n_1 | Hi oanson no worry | 15:10 |
| ad_ri3n_1 | thanks | 15:10 |
| *** fzdarsky_ has quit IRC | 15:10 | |
| kgiusti | hi oanson! | 15:10 |
| *** claudiub|3 has joined #openstack-meeting | 15:10 | |
| ad_ri3n_1 | (BTW the meeting today will be a bit shorter as most of us are travelling today) | 15:11 |
| kgiusti | we're talking dragonflow btw | 15:11 |
| ad_ri3n_1 | kgiusti: please go ahead ;) | 15:11 |
| msimonin | Good timing oanson :) | 15:11 |
| oanson | Great! I'll catch up now :) | 15:11 |
| kgiusti | tl;dr | 15:11 |
| kgiusti | oslo.messaging's current API is not exactly a good fit | 15:11 |
| *** alex_xu has quit IRC | 15:11 | |
| kgiusti | to emulate the API used by dragonflow's pub/sub clients in o.m. would be very heavyweight (in terms of resource use - queues, connections) | 15:12 |
| kgiusti | now investigating different approach - possible have a bespoke AMQP 1.0 driver for dragonflow instead | 15:12 |
| oanson | +1 | 15:12 |
| *** alex_xu has joined #openstack-meeting | 15:13 | |
| kgiusti | or a quick 'n' dirty POC over oslo.messaging to get an accurate sense of cost | 15:13 |
| kgiusti | that's about it | 15:13 |
| oanson | My understanding was that rabbitmq can't handle the distributed load we need? | 15:13 |
| oanson | Or did I miss something? | 15:13 |
| msimonin | kgiusti: you know I'm in for the new oslo.messaging api | 15:14 |
| *** pcaruana has joined #openstack-meeting | 15:14 | |
| msimonin | I really think other project can benefit from it | 15:14 |
| kgiusti | oanson: amqp + router may be able to scale higher | 15:14 |
| oanson | Sure. That makes sense | 15:14 |
| kgiusti | oanson: for a distributed use case, but msimonin et. al. is testing that ATM | 15:15 |
| kgiusti | msimonin: yeah I think it would be very handy too | 15:15 |
| oanson | I see. That's the ombt project? | 15:15 |
| msimonin | rabbitmq is probably not a good fit in a massively distributed environment | 15:15 |
| ad_ri3n_1 | ok what are the actions to conduct? I guess kgiusti you willl discuss about this point during the PTG? | 15:15 |
| kgiusti | ad_ri3n_1: 2 things: propose new API at oslo PTG, and build a POC for dragonflow to kick the tires a bit | 15:16 |
| msimonin | kgiusti: +1 | 15:16 |
| ad_ri3n_1 | ok | 15:16 |
| kgiusti | sadly next week I'm stuck in meetings so I probably won't get much real work started until week after :( | 15:16 |
| *** caowei has quit IRC | 15:17 | |
| ad_ri3n_1 | yes it seems we are all busy with meetings and project submissions :( | 15:17 |
| ad_ri3n_1 | ok | 15:17 |
| msimonin | kgiusti thanks for having done this effort on this ! | 15:17 |
| ad_ri3n_1 | so maybe a new update next time? | 15:17 |
| kgiusti | ad_ri3n_1: yep I think that's reasonable | 15:17 |
| kgiusti | msimonin: my pleasure! | 15:17 |
| ad_ri3n_1 | (thanks msimonin ;) a bit stressed today especially because I have to catch my train in 10 min max) | 15:17 |
| msimonin | I can backup you ad_ri3n_1 if needed | 15:18 |
| *** samP has quit IRC | 15:18 | |
| ad_ri3n_1 | cool | 15:18 |
| ad_ri3n_1 | ;) | 15:18 |
| *** kiennt26_ has quit IRC | 15:18 | |
| ad_ri3n_1 | I was not sure you can attend today. | 15:18 |
| ad_ri3n_1 | OK maybe I can give a few words regarding the gap analysis, especially because I add a todo for myself regarding dragonflow | 15:19 |
| ad_ri3n_1 | kgiusti: anything else? Can i move to the next topic? | 15:19 |
| kgiusti | take the floor, sir! | 15:19 |
| ad_ri3n_1 | Thanks | 15:19 |
| ad_ri3n_1 | #topic ongoing-action-gap-analysis | 15:19 |
| *** openstack changes topic to "ongoing-action-gap-analysis (Meeting topic: fog-edge-massively-distributed-clouds)" | 15:19 | |
| ad_ri3n_1 | so we spent a couple of hours with Inria and Ericsson folks to produce the following etherpad | 15:20 |
| ad_ri3n_1 | #link https://etherpad.openstack.org/p/edge-gap-analysis | 15:20 |
| ad_ri3n_1 | so our goal was to conduct a gap analysis of the different deployment scenarios administrators can leverage to operate a middle edge infrastructure | 15:21 |
| ad_ri3n_1 | so first part we defined the topology we consider | 15:21 |
| ad_ri3n_1 | second part we defined expected features (i.e. operations you would to perform either as a developer/user of the edge infrastructure or as an administrator) | 15:22 |
| ad_ri3n_1 | We defined different levels actually 7 | 15:22 |
| ad_ri3n_1 | The first level include the simplest operations such as provisioning a VM locally | 15:22 |
| ad_ri3n_1 | The last level address interoperability challenges | 15:22 |
| ad_ri3n_1 | in the third part, we analysed different scenarios (i.e. openstack vanilla, cells, regions, federations) according to the aforementioned expected features | 15:23 |
| *** samP has joined #openstack-meeting | 15:23 | |
| ad_ri3n_1 | It would be great if you can go through the analysis and give us comments/feedbacks | 15:23 |
| *** rbrndt has joined #openstack-meeting | 15:23 | |

| *** david-lyle has quit IRC | 15:24 | |
| *** dklyle has joined #openstack-meeting | 15:24 | |
| oanson | Sure. Will do. | 15:24 |
| ad_ri3n_1 | it would be nice to integrate the dragonflow proposal | 15:24 |
| ad_ri3n_1 | in the different deployment scenarios | 15:24 |
| oanson | Would be great for us too :) | 15:24 |
| ad_ri3n_1 | for instance dragonflow and regions | 15:24 |
| ad_ri3n_1 | how this behaves? | 15:24 |
| *** samP has quit IRC | 15:24 | |
| ad_ri3n_1 | so either you can do that offline | 15:24 |
| *** slaweq_ has quit IRC | 15:25 | |
| ad_ri3n_1 | or you can take part to our next discussion which is scheduled friday | 15:25 |
| ad_ri3n_1 | Feb 9th | 15:25 |
| ad_ri3n_1 | at 15:30 Paris time | 15:25 |
| ad_ri3n_1 | that's all from my side ;) | 15:25 |
| oanson | Sure. I'll let you know one way or the other. | 15:25 |
| msimonin | What you mean ad_ri3n_1 is to get tenant network spanning different regions ? | 15:25 |
| ad_ri3n_1 | great | 15:26 |
| ad_ri3n_1 | msimonin: yes | 15:26 |
| ad_ri3n_1 | Level 3 | 15:26 |
| ad_ri3n_1 | features | 15:26 |
| ad_ri3n_1 | sorry Level 4 features | 15:26 |
| msimonin | this would be great actually if oanson can give us some insight on "distributed" tenant network : tenant network over several regions/sites | 15:27 |
| ad_ri3n_1 | oanson: adrien.lebre@inria.fr ;) | 15:27 |

| ad_ri3n_1 | thanks @msimonin | 15:27 |
| oanson | msimonin, are talking one Openstack distribution across sites, or multiple distributions with e.g. l2gw? | 15:27 |
| ad_ri3n_1 | ++ | 15:27 |
| *** samP has joined #openstack-meeting | 15:28 | |
| msimonin | I would say the pros/cons of both solutions | 15:28 |
| msimonin | to address the level of features of the document | 15:28 |
| msimonin | btw oanson are you going to the PTG ? | 15:28 |
| msimonin | I probably missed this information | 15:28 |
| oanson | yes on the PTG | 15:29 |
| oanson | I'll check if I registered in the etherpad after the meeting | 15:29 |

| *** jamesmcarthur has joined #openstack-meeting | 15:29 | |
| *** eharney has quit IRC | 15:29 | |
| oanson | From the Dragonflow PoV, a single deployment is easiest. Easier to configure and manage, and the distributed DB (e.g. etcd, redis) and pub/sub takes care of synchronizing the controllers and hosts | 15:30 |

| jungleboyj | smcginnis: :-) She can talk about how wonderful it is that we got Multi-attach in. | 16:17 |

| jungleboyj | I do think that ildikov is a good choice though. :-) | 16:19 |
| jungleboyj | Even though she is ignoring us. | 16:19 |
| *** belmoreira has joined #openstack-meeting | 16:19 | |
| smcginnis | I didn't hear an objection from her, so I think that means you can sign her up for it. ;) | 16:19 |
| jungleboyj | smcginnis: I like the way you think when you aren't harassing me. | 16:20 |

| jungleboyj | #topic Cisco FC ZM Driver | 16:23 |
| *** openstack changes topic to "Cisco FC ZM Driver (Meeting topic: cinder)" | 16:23 | |
| jungleboyj | So, Cisco is working on getting CI working. | 16:24 |
| *** ad_ri3n_ has joined #openstack-meeting | 16:24 | |
| jungleboyj | It isn't pretty but it is reporting and they have been working on this. | 16:24 |
| smcginnis | They do have one (and only one) test running. | 16:24 |
| jungleboyj | smcginnis: Ok, it is something. | 16:24 |
| *** oidgar has quit IRC | 16:24 | |
| jungleboyj | I wanted to get an idea of what you think smcginnis and if anyone else has opinions. | 16:25 |
| smcginnis | I had worked with Angela in the past and we came up with a list of 13 tests that actually go through the fczm. | 16:25 |
| smcginnis | I think that should apply to Cisco as well. | 16:25 |
| e0ne | I'm ok with this if CI is stable and reporting to the needed patches | 16:25 |
| smcginnis | I need to try to find that though. That was like 2 years ago. | 16:25 |
| smcginnis | e0ne: OK with it now with one test? | 16:26 |
| smcginnis | Not disagreeing, just clarifying. | 16:26 |
| jungleboyj | smcginnis: That sounds reasonable. They should do the same thing as the other FC ZM. | 16:26 |
| *** jbernard has joined #openstack-meeting | 16:27 | |
| smcginnis | That said, I don't think Brocade is reporting anymore now either since the Broadcom acquisition. | 16:27 |
| *** samP has joined #openstack-meeting | 16:27 | |
| jungleboyj | smcginnis: *Laughing* | 16:27 |
| e0ne | smcginnis: one tests doesn't look good enough | 16:27 |
| *** msimonin has left #openstack-meeting | 16:27 | |
| smcginnis | I would be willing to accept "good enough for now" with the understanding that they need to add more tests. | 16:27 |
| e0ne | I'm not expert in FC at all, but I would like to see FC-related tests with some volume backend tests | 16:28 |
| jungleboyj | smcginnis: ++ and then we should follow up with Angela on Brocade. | 16:28 |
| smcginnis | If either is still around... | 16:28 |
| * jungleboyj shakes my head | 16:29 | |
| smcginnis | e0ne: At least the one they have running is volume attach/detach, so it is at least covering the main happy path. | 16:29 |
| jungleboyj | smcginnis: I feel like marking it unsupported had the desired effect. | 16:29 |
| smcginnis | True | 16:30 |
| jungleboyj | smcginnis: Do you have bandwidth to continue working with Liqin Dong? | 16:30 |
| smcginnis | Thermo nuclear option, we remove FCZM from cinder and it's up to Cisco and Brocade/Broadcom to provide this functionality to their end users. I don't like that option though. | 16:30 |
| jungleboyj | I am not a fan of Thermo Nuclear options. | 16:31 |
| smcginnis | jungleboyj: Yeah, I'll try to track down that conversation with Angela and get them the list of expected tests. | 16:31 |
| *** munishmehan has joined #openstack-meeting | 16:31 | |
| smcginnis | ACtually, now that I think of it, I might have been smart enough to add that to the wiki. | 16:31 |
| * smcginnis checks... | 16:31 | |
| Swanson | smcginnis, I like this. Let's give it the ol Kim Jong Un. I can have a patch up for my driver in 15 minutes. | 16:31 |
| *** ricolin has quit IRC | 16:32 | |
| e0ne | smcginnis: attach/detach - is good to start. from my experience, most problems were with FC and migrations. but we didn't use FC zone manager in that deployments | 16:32 |
| * jungleboyj shakes my head at Swanson | 16:32 | |
| smcginnis | e0ne: Oh, good point. | 16:33 |
| jungleboyj | #action smcginnis to follow up with Cisco on tests being run by Broacde. | 16:33 |
| jungleboyj | #action jungleboyj To follow up on state of the Brocade driver. | 16:33 |
| jungleboyj | That all sound good? | 16:34 |
| smcginnis | ++ | 16:34 |
| jungleboyj | Sweet. | 16:34 |
| jungleboyj | #topic Provisioning report bugs: | 16:34 |
| *** openstack changes topic to "Provisioning report bugs: (Meeting topic: cinder)" | 16:34 | |
| jungleboyj | tpsilva: Take it away. | 16:34 |
| tpsilva | alright | 16:34 |
| tpsilva | so, as part of the provisioning improvements, we went through all the drivers checking what they were reporting | 16:35 |
| jungleboyj | Alright ... | 16:35 |
| tpsilva | and we came up with a list of bugs | 16:35 |
| tpsilva | for each driver that had incorrect provisioning reports | 16:36 |
| tpsilva | most of the bugs are pretty simple to fix, so it shouldn't take much | 16:36 |
| jungleboyj | tpsilva: Excellent. | 16:36 |
| tpsilva | but vendors should check this list to see if their drivers are affected | 16:36 |
| *** samP has quit IRC | 16:36 | |
| jungleboyj | #action Vendors need to check if their drivers are impacted and make changes. | 16:37 |
| eharney | it sounds like we could just push these changes rather than requiring driver owners to make them, if the fix is to just not report a value from the driver anymore | 16:37 |
| e0ne | and we should be careful with RemoteFS driver since it can broke some other drivers | 16:37 |
| jungleboyj | eharney: I am ok with that. | 16:38 |
| smcginnis | tpsilva: I think I saw about 5-6 bugs go through. Does that sound right? | 16:38 |
| *** gongysh has quit IRC | 16:38 | |
| tpsilva | smcginnis: I opened 8 bugs | 16:38 |
| erlon | eharney, some of the changes deal with some internal driver logic and we didnt wanted to mess with that | 16:38 |
| tpsilva | the complete list is on the meeting agenda etherpad | 16:38 |
| smcginnis | tpsilva: OK, thank you. | 16:39 |
| jungleboyj | smcginnis: List is in the meeting notes. | 16:39 |

| *** sinese has quit IRC | 16:39 | |
| *** pcaruana has quit IRC | 16:39 | |
| erlon | eharney, and, changing drivers without having the hardware to test means to rely on their CIs, and that use to be a pain | 16:40 |
| jungleboyj | erlon: What is the impact of leaving them as is? | 16:41 |
| eharney | erlon: well that is one of the main reasons that we have all of these CIs... | 16:41 |
| *** ad_ri3n_ has joined #openstack-meeting | 16:41 | |
| *** andreas_s has joined #openstack-meeting | 16:42 | |
| jungleboyj | eharney: True. Assuming they work. | 16:42 |
| eharney | don't they? | 16:42 |
| jungleboyj | eharney: Some do. :-) | 16:43 |
| jungleboyj | eharney: That is a whole other discussion though. | 16:43 |
| *** samP has joined #openstack-meeting | 16:43 | |
| erlon | jungleboyj, true | 16:43 |
| eharney | seems like a reasonable assumption given the numerous man-years put into dealing with them, but i dunno | 16:43 |
| jungleboyj | erlon: Did you see the question about what the impact of leaving drivers as they are? | 16:43 |
| erlon | jungleboyj, I have done some work through several drivers and waiting on CIs to get things tested is very time consuming | 16:44 |
| erlon | eharney, the impact is that those drivers will not behave correctly when using thin provisioning, some will not schedule when they should, other will always create volumes etc | 16:45 |
| jungleboyj | erlon: Ok. | 16:45 |
| erlon | the idea of have then fixed is to have a consistent behaviour on thin provisioning supported drivers | 16:45 |
| jungleboyj | erlon: So, I am looking at this list and it shouldn't be hard for those drivers to get people involved to make sure the right change is pulled in. | 16:47 |
| jungleboyj | Huawei is one of them. I know someone with connections there. :-) | 16:47 |
| jungleboyj | Storwize, same thing. | 16:47 |
| *** dustins has joined #openstack-meeting | 16:47 | |
| jungleboyj | So, let me take this and follow up with people to get it attention. | 16:48 |
| *** sinese has joined #openstack-meeting | 16:48 | |
| jungleboyj | Keep this on the meeting agenda to track progress. | 16:48 |
| jungleboyj | I don't think we want drivers with inconsistent behavior. | 16:48 |
| erlon | jungleboyj, nice! Its good to have vendors involved | 16:48 |
| jungleboyj | erlon: Yeah, I feel they should be involved. If you have patches, that is great, they should review them. | 16:49 |
| jungleboyj | Lucian is active on SMBFS. | 16:49 |
| jungleboyj | eharney: e0ne You guys have the most experience with remotefs. Right? | 16:49 |
| eharney | yes? | 16:50 |
| jungleboyj | That is the one kind-of concerning one as it impacts multiple drivers. | 16:52 |
| jungleboyj | erlon: How complicated is the change there? | 16:52 |

| smcginnis | Just wanted to point, while we are feature and string freeze, now would be a good time to spend time reviewing pike backports. That transitions to Phase II support in just a few weeks. | 16:59 |
| *** VW has joined #openstack-meeting | 16:59 | |
| smcginnis | jungleboyj: I can try to take a look later unless someone else beats me to it. | 16:59 |
| smcginnis | Which would be just fine with me. | 17:00 |
| smcginnis | Times up. | 17:00 |
| jungleboyj | smcginnis: Thank you and thanks for the note on backports! | 17:00 |

| diablo_rojo | Updates as far as talking to teams about migration. | 19:12 |
| *** cloudrancher has quit IRC | 19:13 | |
| diablo_rojo | Circled back to all the teams I reached out to a while ago and they are discussing with their teams, I expect that we will have a team or two to migrate soon. | 19:13 |
| *** liyi has joined #openstack-meeting | 19:13 | |
| diablo_rojo | Still in talks with tripleO about their team moving maybe a few repos at a time- idk. Might suggest chatting at the PTG about it. | 19:13 |
| *** cloudrancher has joined #openstack-meeting | 19:13 | |
| diablo_rojo | I updated the release goal with all the info about teams we have already migrated, have been sucessfully tested, etc. | 19:14 |

| *** tobberydberg__ has quit IRC | 19:14 | |
| diablo_rojo | I tried to start doing some more test migrations today but I'm having issues getting the instance set up. I hit this a few weeks ago on a different install when I was testing and didn't get time to circle back till now. | 19:15 |
| *** tobberydberg__ has joined #openstack-meeting | 19:15 | |
| diablo_rojo | Thats what I need your help with SotK ^^ | 19:15 |
| diablo_rojo | Figuring out what is wrong there. | 19:15 |
| *** amodi has joined #openstack-meeting | 19:15 | |
| diablo_rojo | Ummm... once I get that rolling again I will be able to continue testing and working on the migration patch fix for suspended users that affects i18n and heat. | 19:15 |
| diablo_rojo | I think that is all I have for updates and things. | 19:16 |
| diablo_rojo | I did a ton of reviews over the last few days so we can get some things moving. | 19:16 |
| diablo_rojo | OH | 19:16 |
| diablo_rojo | I do have one more thing. | 19:16 |
| diablo_rojo | but it can wait since its mostly just SotK and I talking to ourselves. | 19:16 |

| mattoliverau | next swift client release will need to support different tempurl hashes, cause that just landed in swift | 21:04 |
| notmyname | and we arent under time pressure (yet) for it. we were on a schedule for the client release, so i did that one first | 21:04 |
| notmyname | mattoliverau: good point | 21:04 |
| notmyname | yeah, so a few last-minute things landing ins wift for 2.17.0 | 21:04 |
| notmyname | the multiple hashes for tempurls is cool | 21:04 |
| mattoliverau | yeah, in no hurry.. we might be able to land some more things so notmyname has to update the changelog again :P | 21:04 |
| notmyname | and the data segements in SLOs is really nice :-) | 21:04 |
| notmyname | yeah, I'll get the changelog updated today or tomorrow and do the tag when it lands | 21:05 |
| timburke | thanks again mattoliverau and cschwede, for looking at the tempurl stuff! i suppose i ought to start on a similar patch for formpost... | 21:05 |
| notmyname | looking ahead to the official queens release... | 21:05 |
| notmyname | I do not know yet if we'll do another 2.18. or 2.17.1 release before the queens deadline | 21:06 |
| mattoliverau | timburke: multpe hashes in the client first, so people can easily use it | 21:06 |
| *** pchavva has quit IRC | 21:06 | |
| *** salv-orlando has quit IRC | 21:06 | |
| notmyname | to some extent, it depends on what lands | 21:06 |
| notmyname | if we do anything, I suspect it would only be a 2.17.1 | 21:06 |
| notmyname | IIRC the deadline for that release is only a couple of weeks away anyway | 21:06 |
| mattoliverau | I added a basic part diff tool.. though maybe it isn't useful to people. It was fun to write tho :P | 21:06 |
| notmyname | so maybe we'll just call this one an early queens release :-) | 21:06 |
| notmyname | mattoliverau: what's that? | 21:07 |
| mattoliverau | i pushed it last night, let me find it | 21:07 |
| timburke | i saw something about that... need to find time to take a look... | 21:07 |

| notmyname | oh, cool | 21:08 |
| *** tobberydberg__ has joined #openstack-meeting | 21:08 | |
| mattoliverau | Just from a discussion on channel the other week. so you can compare builders and rings to see whats different in the replica2parts2dev tables | 21:08 |
| notmyname | yeah, that could be quite useful | 21:09 |
| mattoliverau | tho I don't know if the verbose option is useful.. but is fun :P | 21:09 |
| notmyname | when `swift-recon --md5` gives an error, this tool could tell you how bad it is | 21:09 |
| mattoliverau | might need to add a device diff too. but you can just use ring builder for at least that list | 21:10 |
| mattoliverau | *to the tool | 21:10 |
| notmyname | any question on releases, current or upcoming? | 21:10 |
| timburke | then you realize that you had a part power of 24. then you cry... | 21:10 |
| *** Alex_Staf has quit IRC | 21:10 | |
| timburke | ;-) | 21:10 |
| mattoliverau | yup.. but it look pretty | 21:11 |
| mattoliverau | could strip -v out | 21:11 |
| notmyname | between now and the queens cutoff date, if you see something that's a big bug, that should be priority above new features | 21:11 |

| notmyname | acoles: IMO yes it is, but I'd like to have torgomatic around. well, more people actually. and I think it's something we should talk about at the PTG | 21:12 |
| notmyname | rephrased, I do NOT think it's something we should agree to or decide quickly | 21:13 |

| *** samP has quit IRC | 21:13 | |

| acoles | done | 21:13 |
| mattoliverau | acoles: I'll looking forward to being able to talk sharding at PTG. Sorry I've been a bit in and out regarding reviewing and working on it upstream over the last few weeks. | 21:14 |
| acoles | mattoliverau: NP, I'm also looking forward to a face to face session on it! | 21:14 |

| notmyname | we'll have a room for wed-fri, but I'm sure we'll find a way to talk on monday and tuesday, too | 21:16 |
| notmyname | and it's likely we may also try to find some time for some off-site social activities too | 21:16 |
| mattoliverau | And I found pretty direct flights, so it'll only 26 hours of transit (instead of 30+) so I'm happy :) | 21:17 |

| notmyname | #topic task queue: upgrade impact | 21:23 |
| *** openstack changes topic to "task queue: upgrade impact (Meeting topic: swift)" | 21:23 | |
| notmyname | m_kazuhiro: this is a topic you added to the agenda | 21:23 |
| notmyname | #link https://etherpad.openstack.org/p/swift_general_task_queue | 21:23 |
| notmyname | m_kazuhiro: the floor is yours | 21:23 |
| m_kazuhiro | notmyname: thank you | 21:23 |
| m_kazuhiro | At first, I explain background. | 21:23 |
| m_kazuhiro | I'm implementing patch to update object-expirer now. https://review.openstack.org/#/c/517389/ | 21:25 |
| patchbot | patch 517389 - swift - Update object-expirer to use general task queue sy... | 21:25 |
| m_kazuhiro | This patch makes expier to use general task queue. | 21:25 |
| m_kazuhiro | With general task queue feature, many object-expirers run on a swift cluster. Object-expirer runs on every object-server. | 21:25 |
| *** pchavva has joined #openstack-meeting | 21:25 | |
| m_kazuhiro | The expiratoin tasks are assigned to object-expirers according to partition numbers which their object-server have. | 21:26 |
| m_kazuhiro | To get partition numbers of local object-server, object-expirer requires ip and port information of object-server. Therefore object-expirer's config is moved to object-server.conf's section from sepcial conf file 'object-expirer.conf' in the patch. | 21:26 |
| m_kazuhiro | Hidden task account / container names are changed from original task account / container (hereinafter, we call it "legacy" style). In legacy style, task account / container is only one for a swift cluster. With general task queue feature, there will be many task accounts / containers. | 21:26 |
| m_kazuhiro | To make expirers compatible with legacy style tasks, we can set "execute_legacy_task" flag in object-expirer section in object-server.conf. If the value is True, the object-expirer will execute legacy style tasks. So we can choice which object-expirer runs for legacy style task on object-server. | 21:27 |
| *** rmcall has quit IRC | 21:27 | |
| m_kazuhiro | After the patch, no legacy style expiration tasks are created. Expiration tasks are created only into general tasks queue. | 21:27 |
| *** ganso has quit IRC | 21:28 | |
| m_kazuhiro | About this patch. The discussion points for now are... | 21:28 |
| m_kazuhiro | 1: If swift operators run object-expirer (for legacy style tasks) NOT on object-servers before the patch. They need to redesign where object-expirers for legacy style tasks should run on. This is impact for operator. | 21:29 |
| m_kazuhiro | 2: If swift operators forget to update object-server's [object-expirer] section, there will be error message 'Unable to find object-expirer config section in object-server.conf'. Then, no object-expirers will run. Can we accept the behavior? | 21:29 |
| m_kazuhiro | I want to discuss above points. | 21:31 |
| mattoliverau | thanks m_kazuhiro | 21:31 |
| notmyname | yes, thank you | 21:31 |
| mattoliverau | So in the ehterpad you talk about 2 choices. | 21:31 |
| notmyname | so it's about what happens in a cluster that is using expiring objects after they upgrade to a release that has a task queue | 21:31 |
| mattoliverau | make people migrate to the new expirer configuration or run 2 sets (legacy) and task queue expirers. The former looking at the old config. | 21:32 |
| kota_ | morning | 21:32 |
| *** links has quit IRC | 21:32 | |
| kota_ | sorry slept too much | 21:32 |
| notmyname | kota_: no worries | 21:32 |
| mattoliverau | Having 2 different expirers seems more confusing then just fixing it up on upgrade to me. | 21:33 |
| notmyname | but on the other hand "run this legacy one until the queue is gone" does sound simple | 21:33 |
| mattoliverau | I mean what do we call them, and if people are using automated swift-init or there own systemd init scripts then they may all need to be renamed | 21:34 |
| mattoliverau | yeah | 21:34 |
| notmyname | I suppose the queue may never be gone, if someone has a 7 year expiry or something, though | 21:34 |
| mattoliverau | So it really depends on where your running expirers | 21:34 |
| mattoliverau | it's pretty smooth if it's already on object servers. But obviously more effort on people running them elsewhere (line rledisez I believe) | 21:35 |
| mattoliverau | I put this in the etherpad, while brain storming the steps involved (I might have missed some?) | 21:35 |
| mattoliverau | - Move or create '[object-expirer]' section to object-server configuration (on all object server nodes) | 21:35 |
| mattoliverau | - drop a '/etc/swift/internal-client.conf' if it doesn't exist, or define an internal client location with 'internal_client_conf_path'. | 21:35 |
| mattoliverau | - If you need legacy expirers (not green field and want to clean up old legacy locations): | 21:35 |
| mattoliverau | - if old expirers where on some of the object servers: | 21:35 |
| mattoliverau | - add 'execute_legacy_task = true' to only them so they will still work and take advantage of old existing 'processes' and 'process' settings. | 21:35 |
| mattoliverau | - else: | 21:35 |
| mattoliverau | - pick the same number of expirers to do legacy work. Then you can use the same 'processes' and 'process' settings. Or just pick 1 to do legacy work and don't define 'processes' and 'process'. | 21:36 |
| mattoliverau | - Optionally, if you wish to choose a different task queue account prefix of expirer queue name prefix do so now: | 21:36 |
| mattoliverau | task_account_prefix = ? (default 'task') | 21:36 |
| mattoliverau | expirer_task_container_prefix = ? (default 'expirer'). | 21:36 |
| acoles | is it ok for more than one new style expirer to have execute_legacy_task=true | 21:36 |
| mattoliverau | ok that didn't paste the best.. go look in the etherpad :P | 21:36 |
| mattoliverau | yup, but if you do, you need to use the old legacy processes and process | 21:37 |
| acoles | I mean, per server | 21:37 |
| rledisez | acoles: i should be, I guess it's then needed to set the processes and process | 21:37 |
| rledisez | *it | 21:37 |
| mattoliverau | otherwise we could dos outselves (all hitting the legacy namespace at once) | 21:37 |
| mattoliverau | tho the good news is, even if you decided to only have 1 in legacy mode, we aren't adding to the legacy queue so it'll eventually get through it all | 21:38 |
| timburke | "eventually" | 21:38 |
| mattoliverau | lol | 21:39 |
| mattoliverau | yup | 21:39 |
| mattoliverau | which is why processes and process hasn't disapeared.. just only legacy options now. | 21:39 |
| rledisez | could we decide to have a fixed numbers of legacy process (eg: 32). if there is not 32 object servers, then the values for process/processes would adapt automaticaly | 21:40 |
| rledisez | it would avoid to overload the legacy account/containers, while having some parallelization | 21:40 |
| timburke | maybe legacy processes could process *all* queue entries... if we haven't hit the expiration yet, add an entry to the *new* queue and pop from the old... | 21:41 |
| acoles | anyone wha ran an expirer before is going to want a legacy mode, correct? and potentially forever? | 21:41 |
| rledisez | yes | 21:41 |
| timburke | i hate that "potentially forever" part... | 21:41 |
| acoles | timburke: right, I wondered if legacy tasks could be migrated somehow | 21:42 |
| acoles | but it seems like having legacy mode automatically enabled would be nice | 21:42 |
| *** samP has quit IRC | 21:43 | |
| mattoliverau | but controlling some ellection of nodes to handle legacy starts getting complicated. Because we don't want too many to hit the same legacy namespace. | 21:43 |
| mattoliverau | we could say replica 0 of each.. but at 24 part power that's still alot of servers hitting | 21:44 |
| notmyname | so how should we move forward with this? keep discussing in here? discuss in irc in -swift? keep it in the etherpad? | 21:44 |
| mattoliverau | well firstly.. | 21:44 |
| *** tpsilva has quit IRC | 21:45 | |
| mattoliverau | if legacy might be around "potentually" forever. then in the case of this discussion, I think we want option 2. | 21:45 |
| mattoliverau | only 1 set of expirers (the new ones). | 21:45 |
| mattoliverau | that need to handle legacy | 21:45 |
| *** ansmith has quit IRC | 21:45 | |
| mattoliverau | otherwise we have 2 different expirer daemons and 2 sets of configs | 21:45 |
| kota_ | too bad :'( | 21:46 |
| mattoliverau | I'd rather 1 and either configure them in the why people used to for legecy or some automatic way. | 21:46 |
| mattoliverau | *way | 21:46 |
| *** salv-orlando has joined #openstack-meeting | 21:47 | |
| mattoliverau | It sounds like that where the discussion was going.. so we might be able to progress the question at hand | 21:47 |
| mattoliverau | but happy to take it offline, into etherpad, and definitely discussions at PTG :) | 21:48 |
| rledisez | option 1 is my choice, and we will always have code related to legacy (either legacy expirer or conversion code, because we will never know if everything i converted in all clusters over the world) | 21:48 |
| notmyname | enter the checkpoint release conversation... :-) | 21:48 |
| rledisez | :) | 21:49 |
| mattoliverau | lol | 21:49 |
| *** samP has joined #openstack-meeting | 21:49 | |
| kota_ | lol | 21:49 |
| notmyname | ok, so mattoliverau and rledisez both say option 1 for now, based in part on the concerns from timburke and acoles. so that sounds like a good plan for now | 21:49 |
| mattoliverau | well, offline/etherpad it is ;) | 21:49 |
| notmyname | and we can readdress it at the PTL? (and of course in the etherpad or IRC before then) | 21:50 |
| notmyname | *PTG | 21:50 |
| m_kazuhiro | mattoliverau: Thank you for your leading discussion. | 21:51 |
| acoles | I need to digest this some more, and we should definitely give it time at PTG if not before | 21:51 |
| notmyname | I agree | 21:51 |
| kota_ | acoles: +1 | 21:51 |
