zhiyuan#startmeeting tricircle01:06
openstackMeeting 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

zhiyuan#topic new-l3-model01:06
*** openstack changes topic to "new-l3-model (Meeting topic: tricircle)"01:06
zhiyuanfirst I would like to discuss the new l3 modle01:06
*** donghao has joined #openstack-meeting01:07
zhiyuanas we know, currently a router only support one external gateway01:07
zhiyuanbut in our new model, we need to associate one router with more than one external networks01:07
zhiyuanYipei, is that correct? that's our current problem01:08
*** rcernin has joined #openstack-meeting01:09
Yipeiyes, 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 hint01:10
*** donghao has quit IRC01:12
Yipeiso maybe we need to find another way to add the external network to the non local router01:12
zhiyuanin 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 users01:13
zhiyuanand we automatically create the local and non-local routers01:13
*** Neptu_ has quit IRC01:13
*** slaweq has joined #openstack-meeting01:13
Yipeii think the non local router can be created by users01:14
*** felipemonteiro__ has quit IRC01:14
zhiyuanif so, how to trigger tricircle to attach the local router to bridge network?01:15
*** Neptu has joined #openstack-meeting01:16

Yipeioh, i see. i was oblivious to the case01:17
*** bobmel has joined #openstack-meeting01:17
*** slaweq has quit IRC01:18
zhiyuanyeah, in the new model, both EW and NS traffic need to go through the non-local router01:18
*** ricolin has joined #openstack-meeting01:19
*** gongysh has joined #openstack-meeting01:19
zhiyuanso I suggest to expose only one router01:19
*** pzchen has joined #openstack-meeting01:20
*** yangyapeng has joined #openstack-meeting01:21
*** ricolin has quit IRC01:21
Yipeiyou 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 router01:23
Yipeithe local routers are transparent to users01:24
zhiyuantenant networks and external networks are all attached to the exposed router01:24
Yipeiso the non local router must be created first01:24
zhiyuanno need to distinguish local and non-local01:25
Yipeiok, i see01:25
zhiyuan"tenant networks and external networks are all attached to the exposed router", this is in the user perspective01:26
Yipeiok, i see01:26
*** jamesmcarthur has joined #openstack-meeting01:26
*** liyi has joined #openstack-meeting01:27
zhiyuanhowever, 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-meeting01:29
zhiyuanthere 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 segments01:29
*** diablo_rojo has quit IRC01:30
*** markvoelker has joined #openstack-meeting01:30
Yipeiok, i think i need to investigate the two solutions01:31
zhiyuanI 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 region01:33
*** zhongjun has joined #openstack-meeting01:34
Yipeiok, i will do some research on the routed network solution and update the spec01:35
*** caisan_ has joined #openstack-meeting01:35
zhiyuanfine, you can check if the data model of routed network has some space for us to save the region info01:36
zhiyuannext let's move to the resource deleting patch01:36
zhiyuan#topic reliable resource deletion01:36
*** openstack changes topic to "reliable resource deletion (Meeting topic: tricircle)"01:36
zhiyuanI check the log and find the reason for the error01:37
*** mriedem_afk is now known as mriedem01:37
songI have checked use neutron 40401:37
songbut last day also failed01:37
*** caisan has quit IRC01:37
zhiyuanthe 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 exception01:39
songyes, i think my code is so.01:41
zhiyuanoh, this analysis  is based on your code submitted, after you change the exception to neutron exception, the local neutron still raise exception?01:42
songI have send the error last night in wechart.01:43
zhiyuanso it doesn't ignore the 404 response and return directly in "delete-network"01:43
songit is raised in get network.01:44
songwhen request come from local.01:44
xuzhuangwhat's the exception raised in local neutron?01:46
zhiyuanit's fine for get-network to raise not-found exception, this exception will be wrapped as a 404 response01:47
songin the neutron client line 92 exception_handle_v2.001:47
songI submit a new path today use the neuron exception so you can see the log.01:48
*** cdub has joined #openstack-meeting01:48
*** fnaval has joined #openstack-meeting01:50
*** haint_ has joined #openstack-meeting01:51
zhiyuanok, let's check the log after that.01:53
*** salv-orlando has joined #openstack-meeting01:53
xuzhuangwhen I run the unit test of delete_sg, raise DBNonExistentTable: (sqlite3.OperationalError) no such table: securitygroupportbindings.01:53
xuzhuangI think it should configure the table of securitygroupportbindings in unit test, but haven't worked.01:53
*** Tom-Tom has joined #openstack-meeting01:53
songto xuzhuang have you rerun stack.sh01:54
songif you change database table you need rerun it01:54
*** kiennt26 has joined #openstack-meeting01:54
xuzhuangunit test also need rerun
*** haint93 has quit IRC01:55
*** fnaval has quit IRC01:55
zhiyuanneutron db operation in unit test is simulated in tricircle/tests/unit/utils.py01:55
songI mean if you change the database table after run devstack.01:56
zhiyuansong, xuzhuang's problem is that the needed neutron table in not created in unit test01:56
xuzhuangoh, i haven't changed table01:57
songoh i miss understand it sorry.01:57
*** wanghao has quit IRC01:57
*** salv-orlando has quit IRC01:57
zhiyuanafter you register the table in tests/unit/, what error occurs?01:58
*** wanghao has joined #openstack-meeting01:58
xuzhuangyou mean configed portbinds in _resource_list? I have try this solution, but it haven't worked.01:59
zhiyuanso I am asking the error01:59
zhiyuanyou may also modify " def add(self, model_obj):"01:59
xuzhuangok, i will have a tryp02:00
zhiyuanto save the related resource in self.store_map02:00
*** cdub has quit IRC02:00
xuzhuangI have learned about the mapping of default security group between central and local. But I haven't known02:01
xuzhuangthe relation ship of normal security group between central and local. There is no create_security_group in tricircle,02:01
xuzhuangshould i add this function?02:01
zhiyuantests/unit/ 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 file02:01
xuzhuangok, Got it02:02
zhiyuannetwork/ already inherit securitygroups_db.SecurityGroupDbMixin, no new definition means that the base function is used02:03
*** gongysh has quit IRC02:03
zhiyuanyou can create new SEG via tricircle02:03
xuzhuangok, when deleting security group should i delete the rules belonged this sg firstly?02:04
zhiyuanfor this, you can check if deleting a SEG will delete all the rules under it in Neutron first02:05
zhiyuanif so, you just delete the SEG02:06
xuzhuangok, Got it02:06
zhiyuanso much for today, thanks for attending02:07

*** openstack changes topic to "preemptible instances in OpenStack (Meeting topic: scientific-sig)"11:18
oneswigtoday's main event!11:18
oneswigbelmoreira: how's your reaper project developing?  can you describe it?11:19
belmoreiraI will give the floor to ttsiouts11:19
ttsioutsbelmoreira: thanks!11:19
ttsioutsCurrently, the operators use project quotas for ensuring the fair sharing of their infrastructure.11:20
*** rfolco|off is now known as rfolco11:20
ttsioutsThe problem with this, is that quotas pose as hard limits.11:20
ttsioutsThis leads to actually dedicating resources for workloads even if the resources are not used all the time.11:20
ttsioutsWhich in turn leads to lower cloud utilization11:20
ttsioutsSo there are idle and unused resources when at the same time, the users ask for more resources.11:21
*** donghao has quit IRC11:21
ttsioutsThe concept of Preemptible Instances tries to address to this problem.11:21
*** mdbooth has quit IRC11:21
ttsioutsThis type of servers can be spawned on top of the project's quota, making use of the idling resources.11:21
* johnthetubaguy whoops in agreement11:21
*** wanghao_ has joined #openstack-meeting11:21
oneswigttsiouts: how often does the CERN cloud run out of hosts?11:21
*** andreas_s has quit IRC11:22
belmoreirawe manage quotas and expectations to not happen11:22
ttsioutsHere in Cern we have compute intensive workloads such as batch processing.11:23
ttsioutsFor those, currently we use projects with dedicated quota.11:23
*** mdbooth has joined #openstack-meeting11:23
ttsioutsso 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 IRC11:24
b1airo"dedicated" means that <committed quota> == <available resource> ?11:24
johnthetubaguyI like to think of this as slicing your cloud, like pizza, using quota. you don't want the unused bits going to waste11:24
strigazib1airo it depends on the user11:24
belmoreirab1airo for compute processing yes11:25
ttsioutsjohnthetubaguy: yes11:25
b1airogot it - i understand this might not be true for general purpose instances11:25
*** jamesmcarthur has joined #openstack-meeting11:25
belmoreirab1airo correct11:25
b1airoi assume you control this by segmenting the offerings across AZs or something?11:25
johnthetubaguyso some enterprises hit issues when departments co-fund a cloud, but want to keep the bits they paid for11:26
belmoreiracompute is segmented through cells11:26
*** kopecmartin has joined #openstack-meeting11:26
b1airojohnthetubaguy: yeah we have that problem too11:26
b1airoplease continue ttsiouts11:27
*** andreas_s has joined #openstack-meeting11:27
belmoreirajohnthetubaguy yeah, that is also our main issue11:27
ttsioutsSo currently we are prototyping a service to orchestrate the preemptible instances.11:27
ttsioutsThe "reaper" service!11:27
*** martial_ has joined #openstack-meeting11:27
ttsioutsAs proposed by the Nova team in the latest PTG, the service is external to Nova.11:27
ttsioutsThe 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
ttsioutsThere are various things that have to be addressed here.11:28
ttsioutsThere is the need to tag the preemptible servers with a preepmptible property at creation time.11:29
*** ijw has quit IRC11:29
ttsioutsAnd the property should be immutable.11:29
armstrong@ttsiouts: does CERN uses OpenStack cloud?11:29
*** alexchadin has joined #openstack-meeting11:29
*** jamesmcarthur has quit IRC11:29
belmoreiraarmstrong yes11:30
ttsioutsarmstrong: yes! Openstack is a big thing for Cern.11:30
johnthetubaguyThe 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 things11:30
ttsioutsjohnthetubaguy: +111:31
oneswigttsiouts: johnthetubaguy: can we go over what works and what doesn't?11:31
johnthetubaguythat preemptable property is a good point11:31
oneswigI believe it only partially protects against running out of capacity, right?11:31
*** martial_ has quit IRC11:32
*** alexchadin has quit IRC11:32
johnthetubaguyits more about maximizing utilization, I believe11:32
*** martial_ has joined #openstack-meeting11:33
johnthetubaguyi.e. only stop being able to build servers when you really have no more room11:33
b1airowhat happens when an on-demand request comes in for capacity that is currently filled by preemptible instances?11:34
davehollandhow 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
oneswigjohnthetubaguy: but with an external service, is there an issue that preemptible instances might not be harvested in time when availability requires it?11:34
johnthetubaguyyes, we have the scheduler no valid host triggering the reaper11:34
johnthetubaguyttsiouts: ?11:34
johnthetubaguydid I just make that up :)11:35
ttsioutsThe 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 disconnected11:35
davehollandso the expectation is that the reaper reaps fast enough to be within the overall scheduler timeout?11:35
oneswigttsiouts: From your tests, do higher-level services like Heat cover for the occasional No Valid Hosts, and hide it from the user?11:36
ttsioutsdaveholland: Hopefully yes11:36
*** andreas_s has quit IRC11:36
ttsioutsoneswig: Actually we try to avoid the NoValidHosts exception11:36
*** jamesmcarthur has joined #openstack-meeting11:36
ttsioutsWe trigger the reaper as soon as the placement return no allocation candidates11:37
belmoreiraoneswig this should be hidden for the user11:37
oneswigah, so the failure never makes it back to the API request?11:37
ttsioutsoneswig: yes11:38
oneswigAre you able to signal preemptible instances before they get terminated, or is there simply no time for a grace period?11:38
ttsioutsIf the reaper fails, then we have the NoValidHosts exception raised11:38
johnthetubaguyyeah, this all happens after the create server API has returned11:39
*** markvoelker has joined #openstack-meeting11:39
johnthetubaguybut server will go to error if you can't find room11:39
oneswigjohnthetubaguy: ah, of course, thanks11:39
priteauttsiouts: And that's done without any modification to the nova scheduler code?11:39
johnthetubaguythese are the changes we want to make to nova11:39
b1airoso 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-meeting11:39
johnthetubaguyI think this is in the conductor rather than the scheduler, at least ideally, but thats a technicallity11:40
ttsioutspriteau: the only modification we've done is the triggering of the reaper11:40
ttsioutspriteau: with the same request that is placed to placement11:40
priteauI would love to see the code if you have it public somewhere11:40
johnthetubaguyme too, would love to review where we are11:41
*** tpsilva has joined #openstack-meeting11:41
*** jamesmcarthur has quit IRC11:41
ttsioutspriteau, johnthetubaguy: this is pretty early development stage11:41
johnthetubaguythats all good, just a github branch is fine11:41
belmoreirattsiouts isn't our repo public?11:41
oneswigttsiouts: 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-meeting11:42
ttsioutsbelmoreira: there are several things to be done..11:42
belmoreirayeah, I know. But I though we made it public few time ago11:43
*** thiagomanel has joined #openstack-meeting11:43
ttsioutsI guess we can make it public..11:43
oneswigttsiouts: belmoreira: are there assumptions about cern's use case or is it already generalised11:43
*** alexchadin has quit IRC11:44
oneswigIt seems to have huge potential for many use cases.11:44
johnthetubaguywhere I can see this getting tricky is deciding who gets deleted by the reaper11:44
belmoreiraoneswig initially we would like to run p-instances in dedicated projects11:45
*** Fubica has joined #openstack-meeting11:45
*** jamesmcarthur has joined #openstack-meeting11:45
ttsioutsoneswig: For this prototype the flavors used for spawning this kind of servers are tagged as preemptible.11:45
johnthetubaguybelmoreira: good call out, that's a simplification we can work through later11:45
b1airobelmoreira: we have the same desire - would meet 80% of our need11:45
davehollandI like the flavour/flavor approach, that's easy for users to understand11:45
johnthetubaguyb1airo: interesting11:46
belmoreirajohnthetubaguy just to mentioned that our usecase is not that generic (at least initially)11:46
b1airowe even started spec'ing out a similar project, albeit without the integration and just having a pool of resource dedicated for temporary instances11:46
johnthetubaguydaveholland: +1 (although its a shame you create so many flavors!)11:46
johnthetubaguybelmoreira: +1 although its more general that it first seems11:46
priteaujohnthetubaguy: It would be nice to have a configurable reaper decision engine, like Nova scheduler weighters11:46
johnthetubaguypriteau: I am tempted to go simpler than that, but +1 on the customizable part of that11:47
ttsioutspriteau: Actually we are experimenting with two strategies for selecting servers.11:47
*** thiagomanel_ has joined #openstack-meeting11:47
oneswigHas this got the attention of the public cloud folks yet?11:47
*** thiagomanel has quit IRC11:47
johnthetubaguyttsiouts: I am curious where you settled with that11:47
ttsioutsThe first one maps servers to hosts.11:48
ttsioutsThen it selects a host that could provide the requested resources.11:48
johnthetubaguyoneswig: good point, worth reaching out to that SIG (someone must do reserved instances and live-migrates)11:48
belmoreiradaveholland for our use case we don't see a need for many flavors. We think a small/generic flavor will be enough11:48
martial_oneswig: the PTG is a good option to do just that11:48
ttsioutsand as a last step finds a combination of preemptible servers that will be killed to free up the resources11:48
*** yamamoto_ has quit IRC11:48
ttsioutsThe second strategy tries to eliminate the idling resources.11:48
oneswigHi martial_  - morning11:48
oneswig#chair martial_11:48
openstackCurrent chairs: b1airo martial_ oneswig11:48
ttsioutsSo 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
johnthetubaguymartial_: often don't get many SIG folks at the PTG, at least it feels that way most times11:48
martial_(thanks Stig, been listening)11:49
*** alexchadin has joined #openstack-meeting11:49
*** jamesmcarthur has quit IRC11:49
martial_johnthetubaguy: Tobias (part of the Public Cloud WG) reached out, so I know he is going to be there11:49
oneswigjohnthetubaguy: true, I don't know if they've booked time at the PTG11:49
johnthetubaguymartial_: ah, excellent11:49
oneswigah good11:50
davehollandwe 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 though11:50
* johnthetubaguy hopes we get to flavor decomposition eventually!11:50
belmoreirajohnthetubaguy ahaha :)11:51
oneswigIn an Ironic use case (if indeed there is one), processes like node cleaning could make this a seriously lengthy build time11:51

johnthetubaguyoneswig: its a good point, you may have to wait!11:53
*** salv-orlando has joined #openstack-meeting11:53
johnthetubaguyI like the idea of dropping a mail to the ML for public and scientific SIG, linking to the prototype code11:53
oneswigme too11:53
*** alexchadin has joined #openstack-meeting11:53
b1airothis 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
johnthetubaguyb1airo: +1 bite our tail or something11:54
oneswigThere's a good deal of that!11:54
belmoreiraoneswig never though about an ironic usecase... interesting. But that seems more tricky11:54
*** fnaval has quit IRC11:55
oneswigbelmoreira: signalling the instance on reaping might be harder, there's an nmi that can be injected but who knows what effect it would have11:55
b1airottsiouts: 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-meeting11:56
*** alexchadin has quit IRC11:56
oneswigb1airo: you're right, a good design would provide a nice separation of policy and mechanism11:56
johnthetubaguymost of the extra things seem to boil down to priority of different spot instances11:56

b1airoanyone know how to force the tcp window size default on Windoze servers ?11:59
* johnthetubaguy points at the registry, runs away11:59
b1airoi have some long fat pipe problems to solve between a Windows-based instrument PC and a Linux HPC system in different States...11:59
oneswigb1airo: you may be on your own there :-)12:00
b1airoi guessed as much - for some reason the Windows end doesn't auto-scale the tcp window12:00
oneswigOK, looks like time's up12:00

ad_ri3n_1So 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 expect15:05
ad_ri3n_1I will come back later as I would like to ask you to go and comment it.15:05
ad_ri3n_1Regarding the edge sessions that are done simultaneously, the meeting has been cancelled yesterday15:05
ad_ri3n_1so nothing new15:05

ad_ri3n_1finally regarding the presentations I listed the ones I'm aware about it15:06

ad_ri3n_1if you are aware of others please can you add them.15:07
ad_ri3n_1kgiusti:  ansmith maybe some edge presentations from redhat have been already planned to be submitted ?15:07
kgiustiI'm not specifically aware of any, but we'll ping the right people - ansmith?15:08
ansmithI am not aware but will look into it15:08

ad_ri3n_1can you give us an overwiew?15:10
kgiustiYes - there's interest in adding oslo.messaging support for dragonflow project15:10

kgiustiwe're talking dragonflow btw15:11
ad_ri3n_1kgiusti:  please go ahead ;)15:11
msimoninGood timing oanson :)15:11
oansonGreat! I'll catch up now :)15:11
kgiustioslo.messaging's current API is not exactly a good fit15:11
*** alex_xu has quit IRC15:11
kgiustito 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
kgiustinow investigating different approach - possible have a bespoke AMQP 1.0 driver for dragonflow instead15:12
*** alex_xu has joined #openstack-meeting15:13
kgiustior a quick 'n' dirty POC over oslo.messaging to get an accurate sense of cost15:13
kgiustithat's about it15:13
oansonMy understanding was that rabbitmq can't handle the distributed load we need?15:13
oansonOr did I miss something?15:13
msimoninkgiusti: you know I'm in for the new oslo.messaging api15:14
*** pcaruana has joined #openstack-meeting15:14
msimoninI really think other project can benefit from it15:14
kgiustioanson: amqp + router may be able to scale higher15:14
oansonSure. That makes sense15:14
kgiustioanson: for a distributed use case, but msimonin et. al. is testing that ATM15:15
kgiustimsimonin: yeah I think it would be very handy too15:15
oansonI see. That's the ombt project?15:15
msimoninrabbitmq is probably not a good fit in a massively distributed environment15:15
ad_ri3n_1ok what are the actions to conduct? I guess kgiusti you willl discuss about this point during the PTG?15:15
kgiustiad_ri3n_1: 2 things: propose new API at oslo PTG, and build a POC for dragonflow to kick the tires a bit15:16
msimoninkgiusti:  +115:16
kgiustisadly next week I'm stuck in meetings so I probably won't get much real work started until week after :(15:16

kgiustiad_ri3n_1: yep I think that's reasonable15:17
kgiustimsimonin: 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

*** kiennt26_ has quit IRC15:18
ad_ri3n_1I  was not sure you can attend today.15:18
ad_ri3n_1OK maybe I can give a few words regarding the gap analysis, especially because I add a todo for myself regarding dragonflow15:19
ad_ri3n_1kgiusti:  anything else? Can i move to the next topic?15:19
kgiustitake the floor, sir!15:19
ad_ri3n_1#topic ongoing-action-gap-analysis15:19
*** openstack changes topic to "ongoing-action-gap-analysis (Meeting topic: fog-edge-massively-distributed-clouds)"15:19
ad_ri3n_1so we spent a couple of hours with Inria and Ericsson folks to produce the following etherpad15:20
ad_ri3n_1so our goal was to conduct a gap analysis of the different deployment scenarios administrators can leverage to operate a middle edge infrastructure15:21
ad_ri3n_1so first part we defined the topology we consider15:21
ad_ri3n_1second 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_1We defined different levels actually 715:22
ad_ri3n_1The first level include the simplest operations such as provisioning a VM locally15:22
ad_ri3n_1The last level address interoperability challenges15:22
ad_ri3n_1in the third part, we analysed different scenarios (i.e. openstack vanilla, cells, regions, federations) according to the aforementioned expected features15:23
*** samP has joined #openstack-meeting15:23
ad_ri3n_1It would be great if you can go through the analysis and give us comments/feedbacks15:23

ad_ri3n_1for instance dragonflow and regions15:24
ad_ri3n_1how this behaves?15:24
*** samP has quit IRC15:24

ad_ri3n_1that's all from my side ;)15:25
oansonSure. I'll let you know one way or the other.15:25
msimoninWhat you mean ad_ri3n_1 is to get tenant network spanning different regions ?15:25

ad_ri3n_1Level 315:26

oansonFrom 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 hosts15:30

*** openstack changes topic to "Cisco FC ZM Driver (Meeting topic: cinder)"16:23
jungleboyjSo, Cisco is working on getting CI working.16:24
*** ad_ri3n_ has joined #openstack-meeting16:24
jungleboyjIt isn't pretty but it is reporting and they have been working on this.16:24
smcginnisThey do have one (and only one) test running.16:24
jungleboyjsmcginnis: Ok, it is something.16:24
*** oidgar has quit IRC16:24
jungleboyjI wanted to get an idea of what you think smcginnis  and if anyone else has opinions.16:25
smcginnisI 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
smcginnisI think that should apply to Cisco as well.16:25
e0neI'm ok with this if CI is stable and reporting to the needed patches16:25
smcginnisI need to try to find that though. That was like 2 years ago.16:25
smcginnise0ne: OK with it now with one test?16:26
smcginnisNot disagreeing, just clarifying.16:26
jungleboyjsmcginnis:  That sounds reasonable.  They should do the same thing as the other FC ZM.16:26
*** jbernard has joined #openstack-meeting16:27
smcginnisThat said, I don't think Brocade is reporting anymore now either since the Broadcom acquisition.16:27
*** samP has joined #openstack-meeting16:27
jungleboyjsmcginnis:  *Laughing*16:27
e0nesmcginnis: one tests doesn't look good enough16:27
*** msimonin has left #openstack-meeting16:27
smcginnisI would be willing to accept "good enough for now" with the understanding that they need to add more tests.16:27
e0neI'm not expert in FC at all, but I would like to see FC-related tests with some volume backend tests16:28
jungleboyjsmcginnis:  ++ and then we should follow up with Angela on Brocade.16:28
smcginnisIf either is still around...16:28
* jungleboyj shakes my head16:29
smcginnise0ne: At least the one they have running is volume attach/detach, so it is at least covering the main happy path.16:29
jungleboyjsmcginnis:  I feel like marking it unsupported had the desired effect.16:29
jungleboyjsmcginnis:  Do you have bandwidth to continue working with Liqin Dong?16:30
smcginnisThermo 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
jungleboyjI am not a fan of Thermo Nuclear options.16:31
smcginnisjungleboyj: 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-meeting16:31
smcginnisACtually, now that I think of it, I might have been smart enough to add that to the wiki.16:31
* smcginnis checks...16:31
Swansonsmcginnis, 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 IRC16:32
e0nesmcginnis: 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 deployments16:32

smcginnise0ne: Oh, good point.16:33

*** openstack changes topic to "Provisioning report bugs: (Meeting topic: cinder)"16:34
jungleboyjtpsilva: Take it away.16:34
tpsilvaso, as part of the provisioning improvements, we went through all the drivers checking what they were reporting16:35
jungleboyjAlright ...16:35
tpsilvaand we came up with a list of bugs16:35
tpsilvafor each driver that had incorrect provisioning reports16:36
tpsilvamost of the bugs are pretty simple to fix, so it shouldn't take much16:36
jungleboyjtpsilva:  Excellent.16:36
tpsilvabut vendors should check this list to see if their drivers are affected16:36
*** samP has quit IRC16:36
jungleboyj#action Vendors need to check if their drivers are impacted and make changes.16:37
eharneyit 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 anymore16:37
e0neand we should be careful with RemoteFS driver since it can broke some other drivers16:37
jungleboyjeharney:  I am ok with that.16:38
smcginnistpsilva: I think I saw about 5-6 bugs go through. Does that sound right?16:38
*** gongysh has quit IRC16:38
tpsilvasmcginnis: I opened 8 bugs16:38
erloneharney, some of the changes deal with some internal driver logic and we didnt wanted to mess with that16:38
tpsilvathe complete list is on the meeting agenda etherpad16:38
smcginnistpsilva: OK, thank you.16:39
jungleboyjsmcginnis:  List is in the meeting notes.16:39
*** ad_ri3n_ has quit IRC16:39
*** sinese has quit IRC16:39
*** pcaruana has quit IRC16:39
erloneharney, and, changing drivers without having the hardware to test means to rely on their CIs, and that use to be a pain16:40
jungleboyjerlon:  What is the impact of leaving them as is?16:41
eharneyerlon: well that is one of the main reasons that we have all of these CIs...16:41
*** ad_ri3n_ has joined #openstack-meeting16:41
*** andreas_s has joined #openstack-meeting16:42
jungleboyjeharney:  True.  Assuming they work.16:42
eharneydon't they?16:42
jungleboyjeharney:  Some do.  :-)16:43
jungleboyjeharney:  That is a whole other discussion though.16:43
*** samP has joined #openstack-meeting16:43
erlonjungleboyj, true16:43
eharneyseems like a reasonable assumption given the numerous man-years put into dealing with them, but i dunno16:43
jungleboyjerlon:  Did you see the question about what the impact of leaving drivers as they are?16:43
erlonjungleboyj, I have done some work through several drivers and waiting on CIs to get things tested is very time consuming16:44
erloneharney, 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 etc16:45
jungleboyjerlon:  Ok.16:45
erlonthe idea of have then fixed is to have a consistent behaviour on thin provisioning supported drivers16:45
jungleboyjerlon:  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
jungleboyjHuawei is one of them.  I know someone with connections there.  :-)16:47
jungleboyjStorwize, same thing.16:47
*** dustins has joined #openstack-meeting16:47
jungleboyjSo, let me take this and follow up with people to get it attention.16:48
*** sinese has joined #openstack-meeting16:48
jungleboyjKeep this on the meeting agenda to track progress.16:48
jungleboyjI don't think we want drivers with inconsistent behavior.16:48
erlonjungleboyj, nice! Its good to have vendors involved16:48
jungleboyjerlon:  Yeah, I feel they should be involved.  If you have patches, that is great, they should review them.16:49
jungleboyjLucian is active on SMBFS.16:49
jungleboyjeharney: e0ne  You guys have the most experience with remotefs.  Right?16:49
jungleboyjThat is the one kind-of concerning one as it impacts multiple drivers.16:52
jungleboyjerlon: How complicated is the change there?16:52

*** openstack changes topic to "releases (Meeting topic: swift)"21:02
notmynamefirst up, releases21:02
notmynamewe've done a swiftclient release (it took a long time in the gate, but it's done now)21:03
notmynameand swift itself is getting ready for a 2.17.0 release21:03
notmynameI know I may have given the impression of doing the 2.17.0 release sooner, but I was waiting on a patch and I was traveling :-)21:03
mattoliveraunext swift client release will need to support different tempurl hashes, cause that just landed in swift21:04
notmynameand we arent under time pressure (yet) for it. we were on a schedule for the client release, so i did that one first21:04
notmynamemattoliverau: good point21:04
notmynameyeah, so a few last-minute things landing ins wift for 2.17.021:04
notmynamethe multiple hashes for tempurls is cool21:04
mattoliverauyeah, in no hurry.. we might be able to land some more things so notmyname has to update the changelog again :P21:04
notmynameand the data segements in SLOs is really nice :-)21:04
notmynameyeah, I'll get the changelog updated today or tomorrow and do the tag when it lands21:05
timburkethanks again mattoliverau and cschwede, for looking at the tempurl stuff! i suppose i ought to start on a similar patch for formpost...21:05
notmynamelooking ahead to the official queens release...21:05
notmynameI do not know yet if we'll do another 2.18. or 2.17.1 release before the queens deadline21:06

notmynameif we do anything, I suspect it would only be a 2.17.121:06
notmynameIIRC the deadline for that release is only a couple of weeks away anyway21:06
mattoliverauI added a basic part diff tool.. though maybe it isn't useful to people. It was fun to write tho :P21:06
notmynameso maybe we'll just call this one an early queens release :-)21:06

mattoliverauJust from a discussion on channel the other week. so you can compare builders and rings to see whats different in the replica2parts2dev tables21:08
notmynameyeah, that could be quite useful21:09
mattoliverautho I don't know if the verbose option is useful.. but is fun :P21:09
notmynamewhen `swift-recon --md5` gives an error, this tool could tell you how bad it is21:09
mattoliveraumight need to add a device diff too. but you can just use ring builder for at least that list21:10

notmyname#topic task queue: upgrade impact21:23
*** openstack changes topic to "task queue: upgrade impact (Meeting topic: swift)"21:23
notmynamem_kazuhiro: this is a topic you added to the agenda21:23
notmynamem_kazuhiro: the floor is yours21:23
m_kazuhironotmyname: thank you21:23
m_kazuhiroAt first, I explain background.21:23
m_kazuhiroI'm implementing patch to update object-expirer now.
patchbotpatch 517389 - swift - Update object-expirer to use general task queue sy...21:25
m_kazuhiroThis patch makes expier to use general task queue.21:25
m_kazuhiroWith 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-meeting21:25
m_kazuhiroThe expiratoin tasks are assigned to object-expirers according to partition numbers which their object-server have.21:26
m_kazuhiroTo 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_kazuhiroHidden 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_kazuhiroTo 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 IRC21:27
m_kazuhiroAfter the patch, no legacy style expiration tasks are created. Expiration tasks are created only into general tasks queue.21:27
*** ganso has quit IRC21:28
m_kazuhiroAbout 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_kazuhiroI want to discuss above points.21:31
mattoliverauthanks m_kazuhiro21:31
notmynameyes, thank you21:31
mattoliverauSo in the ehterpad you talk about 2 choices.21:31
notmynameso it's about what happens in a cluster that is using expiring objects after they upgrade to a release that has a task queue21:31
mattoliveraumake 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
*** links has quit IRC21:32
kota_sorry slept too much21:32
notmynamekota_: no worries21:32
mattoliverauHaving 2 different expirers seems more confusing then just fixing it up on upgrade to me.21:33
notmynamebut on the other hand "run this legacy one until the queue is gone" does sound simple21:33
mattoliverauI 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 renamed21:34
notmynameI suppose the queue may never be gone, if someone has a 7 year expiry or something, though21:34
mattoliverauSo it really depends on where your running expirers21:34
mattoliverauit'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
mattoliverauI 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
acolesis it ok for more than one new style expirer to have execute_legacy_task=true21:36
mattoliverauok that didn't paste the best.. go look in the etherpad :P21:36
mattoliverauyup, but if you do, you need to use the old legacy processes and process21:37
acolesI mean, per server21:37
rledisezacoles: i should be, I guess it's then needed to set the processes and process21:37
mattoliverauotherwise we could dos outselves (all hitting the legacy namespace at once)21:37
mattoliverautho 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 all21:38
mattoliverauwhich is why processes and process hasn't disapeared.. just only legacy options now.21:39
rledisezcould 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 automaticaly21:40
rledisezit would avoid to overload the legacy account/containers, while having some parallelization21:40
timburkemaybe 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
acolesanyone wha ran an expirer before is going to want a legacy mode, correct? and potentially forever?21:41
timburkei hate that "potentially forever" part...21:41
acolestimburke: right, I wondered if legacy tasks could be migrated somehow21:42
acolesbut it seems like having legacy mode automatically enabled would be nice21:42
*** samP has quit IRC21:43
mattoliveraubut 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
mattoliverauwe could say replica 0 of each.. but at 24 part power that's still alot of servers hitting21:44
notmynameso how should we move forward with this? keep discussing in here? discuss in irc in -swift? keep it in the etherpad?21:44
mattoliverauwell firstly..21:44
*** tpsilva has quit IRC21:45
mattoliverauif legacy might be around "potentually" forever. then in the case of this discussion, I think we want option 2.21:45
mattoliverauonly 1 set of expirers (the new ones).21:45
mattoliverauthat need to handle legacy21:45
*** ansmith has quit IRC21:45
mattoliverauotherwise we have 2 different expirer daemons and 2 sets of configs21:45
kota_too bad :'(21:46
mattoliverauI'd rather 1 and either configure them in the why people used to for legecy or some automatic way.21:46
*** salv-orlando has joined #openstack-meeting21:47
mattoliverauIt sounds like that where the discussion was going.. so we might be able to progress the question at hand21:47
mattoliveraubut happy to take it offline, into etherpad, and definitely discussions at PTG :)21:48
rledisezoption 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
notmynameenter the checkpoint release conversation... :-)21:48
*** samP has joined #openstack-meeting21:49
notmynameok, 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 now21:49
mattoliverauwell, offline/etherpad it is ;)21:49
notmynameand we can readdress it at the PTL? (and of course in the etherpad or IRC before then)21:50
m_kazuhiromattoliverau: Thank you for your leading discussion.21:51
