| tonyb | \o | 07:00 |
| tonyb | mattoliverau: how is Germany? | 07:00 |
| mattoliverau | Kinda, at a hotel at breakfast.. and still need to make it to the office, so might need to leave early | 07:00 |
| mattoliverau | Yeah NUE is really nice. | 07:00 |
| mattoliverau | Hotel is in the old town, so beautiful. | 07:01 |
| tonyb | mattoliverau: pfft you can't leave! | 07:01 |
| tonyb | mattoliverau: cool | 07:01 |
| mattoliverau | tonyb: lol | 07:01 |
| cmurphy | morning | 07:01 |
| diablo_rojo | Don't have a ton to discuss this week so it shouldn't take the whole hour I don't think. | 07:01 |
| mattoliverau | If I was roaming I'd meeting while walking. But don't need to leave for about 30 - 40 mins | 07:02 |
| * tonyb will *try* to not be a distraction | 07:02 | |
| mattoliverau | Good luck :p | 07:02 |
| diablo_rojo | #link https://wiki.openstack.org/wiki/First_Contact_SIG#Meeting_Agenda Meeting Agenda | 07:02 |

| *** yamamoto has joined #openstack-meeting | 07:03 | |
| mattoliverau | So I've been distracted and haven't done my homework this week, :s | 07:03 |
| tonyb | None for me ... noone new loves the projects I can help with | 07:04 |
| *** rcernin has quit IRC | 07:04 | |
| diablo_rojo | I definitely didn't do my homework either. | 07:04 |
| diablo_rojo | I was bad. | 07:04 |
| mattoliverau | There looks like a swift one from December.. ill go make sure it's getting some love. And I'll try and hit up some others if I get some spare time today. | 07:05 |
| diablo_rojo | Thanks mattoliverau | 07:06 |
| *** lpetrut has joined #openstack-meeting | 07:06 | |
| diablo_rojo | Okay well.. I guess we should all try to go look at patches when we get ten spare minutes at some point today/tomorrow | 07:06 |
| diablo_rojo | Moving on... | 07:06 |
| diablo_rojo | #link Ask.o.o Monitoring | 07:07 |
| diablo_rojo | oops | 07:07 |
| diablo_rojo | lol | 07:07 |
| diablo_rojo | #topic Ask.o.o Monitoring | 07:07 |
| *** openstack changes topic to "Ask.o.o Monitoring (Meeting topic: fc_sig)" | 07:07 | |
| diablo_rojo | There we go. | 07:07 |
| diablo_rojo | I blame the nap I took that made me more tired. | 07:07 |
| diablo_rojo | Anyone do this homework? | 07:07 |
| diablo_rojo | I think I added another softball question for someone to answer | 07:08 |
| mattoliverau | No, but can look now :p | 07:08 |
| *** yamamoto has quit IRC | 07:08 | |
| diablo_rojo | mattoliverau, after the meeting works too | 07:08 |
| * tonyb always forgets that homework | 07:09 | |
| diablo_rojo | Even though it stays in the agenda ;) | 07:09 |
| diablo_rojo | I suppose it is a completely separate site | 07:10 |
| tonyb | diablo_rojo: Yeah I need to bookmark it so I at least go there daily | 07:10 |
| mattoliverau | Or wedsday arvo tonyb :p | 07:11 |
| diablo_rojo | Daily is pretty steep, but if you can manage it go for it. | 07:11 |
| tonyb | mattoliverau: +1 | 07:11 |
| diablo_rojo | So I guess moral of the story here is go find my easy question and answer it. Winner gets a beer in Denver from me. | 07:12 |
| diablo_rojo | Moving on? | 07:12 |

| *** openstack changes topic to "Sandbox Bot (Meeting topic: fc_sig)" | 07:12 | |
| mattoliverau | I asnwered the non code contribution question ;) | 07:12 |
| mattoliverau | Man I can't type today | 07:13 |
| mattoliverau | I'll blame the fact that I'm jetlagged and on my phone :p | 07:13 |
| * tonyb hasn't done anything about the bot :( | 07:14 | |
| tonyb | ... which is silly because I was looking for fun stuff last week | 07:14 |
| diablo_rojo | Hopefully you are looking for something fun for the rest of this week? or next week tonyb? :) | 07:15 |
| tonyb | diablo_rojo: I hope so | 07:16 |
| tonyb | diablo_rojo: probably my Friday morning | 07:16 |
| diablo_rojo | Nothing else on this topic then for now? | 07:17 |
| mattoliverau | Nope | 07:17 |
| *** alex_xu has joined #openstack-meeting | 07:18 | |

| diablo_rojo | #topic Reqs for Organisations Contributing to OpenStack | 07:18 |
| *** openstack changes topic to "Reqs for Organisations Contributing to OpenStack (Meeting topic: fc_sig)" | 07:18 | |
| diablo_rojo | Still waiting on the board of directions elections to complete before proposing it for an agenda item | 07:19 |
| mattoliverau | Kk | 07:19 |
| diablo_rojo | Basically just kept this topic so that I could remind you all to vote in the election. | 07:19 |
| tonyb | they have less than a week left right? | 07:19 |
| diablo_rojo | Yeah | 07:20 |
| * diablo_rojo looks for end date | 07:20 | |

| diablo_rojo | #topic People to Reach Out to | 07:23 |
| *** openstack changes topic to "People to Reach Out to (Meeting topic: fc_sig)" | 07:23 | |
| * tonyb did not reach out to his person | 07:23 | |
| diablo_rojo | Looks like I had a todo, tonyb had a todo, and so did mattoliverau | 07:23 |
| diablo_rojo | I didn't do it yet but I will this week | 07:24 |
| mattoliverau | I emailed the person.. so far no response :( | 07:24 |
| mattoliverau | I emailed pre Christmas. Maybe time for a polite follow up | 07:24 |
| diablo_rojo | I feel like we should make an etherpad or ethercalc to keep track of these people and if we have contacted them, when we did, etc. | 07:25 |
| diablo_rojo | Someone want to do that? | 07:25 |
| * tonyb will | 07:25 | |
| tonyb | Well I'll create the EtherCalc y'all will need to fill it in ;P | 07:26 |
| diablo_rojo | #action tonyb will make an etherpad/calc for tracking people to contact & details of contacting them | 07:26 |
| diablo_rojo | Can do | 07:26 |
| diablo_rojo | Anything else here? | 07:27 |
| mattoliverau | Not from me | 07:29 |
| tonyb | nope. saving myself for open discussion | 07:29 |
| diablo_rojo | #topic Open Discussion | 07:29 |
| *** openstack changes topic to "Open Discussion (Meeting topic: fc_sig)" | 07:29 | |
| diablo_rojo | WRT Denver | 07:30 |
| diablo_rojo | mattoliverau, gonna do OUI? | 07:30 |
| mattoliverau | Yes!.. well I'll ask SUSE to let me go and take it from there :) | 07:30 |
| tonyb | Pfft I was going to ask that | 07:30 |
| * tonyb feels redundant :/ | 07:30 | |
| mattoliverau | tonyb: are you going to do OUI? | 07:31 |
| *** apetrich has joined #openstack-meeting | 07:31 | |
| tonyb | mattoliverau: Yup | 07:31 |
| cmurphy | is OUI going to be sat+sun before summit? | 07:32 |
| tonyb | mattoliverau: Well I have the travel request in it hasn't been approved yet | 07:32 |
| diablo_rojo | tonyb, gotta type faster ;) | 07:32 |
| diablo_rojo | cmurphy, yep | 07:32 |
| diablo_rojo | Can you come too? :) | 07:32 |
| cmurphy | tentatively | 07:32 |
| tonyb | \o/ | 07:32 |

| tonyb | .me will have to find more RedHatters to come | 07:33 |
| diablo_rojo | Gonna be a party! | 07:33 |
| diablo_rojo | The only other thing I have to mention before wrapping up is the CFP is open still | 07:37 |
| tonyb | I have one more thing .... | 07:37 |
| diablo_rojo | so if there is anything we wanted to submit, should probably think about that soon | 07:37 |
| diablo_rojo | tonyb, what is it? | 07:38 |
| tonyb | What's the preferred landing page to point people at to find the FC SIG | 07:38 |
| diablo_rojo | the wiki as of right now | 07:38 |
| tonyb | I pointed a person at: | 07:38 |
| tonyb | [1] https://governance.openstack.org/tc/reference/help-most-needed.html | 07:38 |
| diablo_rojo | I saw the thing on Docs for SIGS | 07:38 |
| tonyb | [2] https://www.openstack.org/community/ | 07:38 |
| tonyb | [3] https://wiki.openstack.org/wiki/First_Contact_SIG | 07:38 |
| tonyb | but the last one doesn't really tell people how to find us | 07:38 |
| diablo_rojo | I suppose we could be more direct. | 07:39 |
| tonyb | I'm gladd I didn't miss it | 07:39 |
| diablo_rojo | Email whoever fits your tz better or jump in #openstack dev and ping us | 07:39 |
| tonyb | We could add a section at the bootom of that wiki page | 07:39 |
| mattoliverau | Good idea | 07:39 |
| diablo_rojo | I think I would put it right under the chairs and members\ | 07:40 |
| tonyb | Okay, it's a wiki so I'll add something and we can bikshed on it :) | 07:41 |
| diablo_rojo | Perfect :) | 07:42 |
| diablo_rojo | Oh, I do have one more thing I guess | 07:42 |
| diablo_rojo | How much time, if any do we think we want/need at the PTG? | 07:42 |
| tonyb | quick mattoliverau's gotta go ;P | 07:43 |
| * diablo_rojo waits for an answer and then will end meeting right after | 07:43 | |
| tonyb | 0.5 days + hallway track? | 07:43 |
| mattoliverau | At least I catch up session, maybe a who are we (intro session). | 07:43 |
| tonyb | Or perhaps just the hallway track | 07:43 |
| mattoliverau | Contribution and company guide update/next steps? | 07:44 |
| diablo_rojo | Okay I will request a half day then | 07:44 |
| *** iyamahat has joined #openstack-meeting | 07:44 | |
| *** imsurit_ofc has quit IRC | 07:45 | |
| mattoliverau | Tho yeah, that could be covered in 0.5 and or hallway | 07:45 |
| diablo_rojo | Nothing for the CFP though? | 07:46 |
| diablo_rojo | we can talk about Forum sessions next time | 07:46 |
| *** radeks has quit IRC | 07:46 | |
| tonyb | Sounds like a plan | 07:46 |
| gmann | o/ sorry missed the meeting. | 07:47 |
| mattoliverau | Oh maybe.. I gotta go, I'll think about it and let's chat maybe if we think of something in the oui channel | 07:47 |
| mattoliverau | Re: cfp | 07:47 |
| diablo_rojo | If you have an idea for the cfp ping me, otherwise I will consider it a no | 07:47 |
| * gmann will read log | 07:47 | |
| mattoliverau | Kk | 07:47 |

| oneswig | #topic AAI for Medical Research Computing | 11:20 |
| *** openstack changes topic to "AAI for Medical Research Computing (Meeting topic: scientific-sig)" | 11:20 | |
| oneswig | We have a guest speaker today - Xi0s from Oxford Big Data Institute | 11:20 |
| oneswig | Thanks for coming Xi0s | 11:20 |
| oneswig | I saw his talk at CIUK 2018 and found it really informative | 11:21 |
| Xi0s | No problem, I hope the content will be of some use to folks | 11:21 |
| oneswig | #link Presentation slides https://www.dropbox.com/s/kvszibl5c0ijk13/AAI%20in%20Rescomp.pptx?dl=0 | 11:21 |
| oneswig | Xi0s: could you give a bit of context on what you were wanting to do? | 11:21 |
| noggin143_ | thanks, i'll pass it on to our AAI team | 11:21 |
| Xi0s | Sure, so we're moving from simple genomics compute into a world of increasingly sensitive data requirements as we expand to support medical sciences at the university, and as such we've been building a lot of new services to support this | 11:22 |
| oneswig | This line looks key today: "Single user identity and password store across all services" | 11:23 |
| Xi0s | Core to this is a new OpenStack deployment, for which we wanted to implement a proper AAI underneath that could do 2FA for anyone and everyone in an enforceable and audit-able way | 11:23 |
| *** ttsiouts has quit IRC | 11:24 | |
| Xi0s | exactly that, so single identity across the cluster, with a single password and single 2FA token registration, rather than per-service implementations | 11:24 |
| oneswig | What was the second factor - a token to a mobile? | 11:25 |
| Xi0s | it depends, mobile token (google authenticator) is easy, but has it's limitations | 11:25 |
| Xi0s | no less, a boss that uses a Nokia 3310 - so we also support physical tokens (Yubikey for example) | 11:25 |
| noggin143_ | did you need a special sshd or was the 2FA standard? | 11:26 |
| Xi0s | standard | 11:26 |
| Xi0s | one of the driving requirements was that we can't afford the pain of distributing custom clients to users | 11:26 |
| Xi0s | so openssh on the clientside supports the multi-factor auth as does the sshd on the server side | 11:28 |
| oneswig | The second factor is described as optional (slide 13), what happens if it is not supplied? | 11:28 |
| *** t0rrant has joined #openstack-meeting | 11:28 | |
| Xi0s | depends on the authentication protocol being used, but in summary, when the auth server receives the request, it will check your account as to whether 2FA is required (at the account or host or other level) and then act appropriately based on that | 11:29 |
| Xi0s | because sshd<->sssd integration is pretty good, when you authentcate using ssh the client will (more or less) be aware as to whether your 2FA is required or not, and inform the user as to whether they have to specify it or not | 11:30 |
| oneswig | So you can still have machine-to-machine service accounts which can authenticate in a non-interactive way | 11:30 |
| Xi0s | yes, in theory, though we've not seen that in practice yet | 11:31 |
| oneswig | How does this play with things like Ansible? | 11:31 |
| Xi0s | support for ssh-keys and certificate-based auth is in there too | 11:31 |
| Xi0s | in what context? (our deployment of all the actors in the AAI was done by ansible - though we don't use any service provided in this for credential store for ansible) | 11:32 |
| oneswig | If I wanted to configure instances deployed with 2FA enabled, for example. | 11:33 |
| oneswig | (as a user) | 11:33 |
| Xi0s | interesting question - in theory if you are deploying 2FA you should apply it to _all_ instances and services you run as an admin, else you have a weak link that could be exploited | 11:34 |
| daveholland | is the 2FA service intended for user-created instances/websites; or did you apply it to the OpenStack API/Horizon too? | 11:34 |
| Xi0s | it will be applied to the API/Horizon, but also available for user-created instances | 11:35 |
| Xi0s | so, because we have a number of auth-proxies, we can more or less support whatever service the user wants to enable, whether its a web-service or desktop login, etc | 11:35 |
| Xi0s | however, this is a manual process, to ensure that you don't end up exposing user credentials to a maliciously crafted service | 11:36 |
| Xi0s | (see: OAuth credentials leak from Google Docs ~2017?) | 11:36 |
| oneswig | Where is the policy on whether an account requires 2FA stored? Is it possible to be more selective (eg, using source address)? | 11:37 |
| Xi0s | policy is done at the central auth server (freeIPA), and in _theory_ you could have step-up authentication either at a service level, host level, or indeed source address (though the latter is not implemented) - however due to limitations on the LDAP authentication protocol and the _current_ intergration with the web-proxy we have to either force on or force off for an account | 11:38 |
| Xi0s | which, for us, meets the requirement of flagging users who have access to potentially sensitive data - however there is more work to be done on these tools for a more versatile service | 11:39 |
| Xi0s | the key limitation (for us) is that Keycloak<-->sssd integration doesn't account for password expiry | 11:39 |
| oneswig | You mention federated accounts - what can you do for those? | 11:40 |
| Xi0s | so I love federation, the idea of not having to deal with user-password enquiries makes me excited - so we do have support for federated identity to a point | 11:41 |
| Xi0s | so, allowing github or facebook authentication and linking those identities to our internal identities so that users can authenticate from an external source | 11:41 |
| oneswig | EGI Checkin? | 11:41 |
| Xi0s | yes, for sure | 11:42 |
| Xi0s | however, it would only work for the web-based authentication at the moment | 11:42 |
| oneswig | true. Although I thought Indigo-DataCloud had a solution for the command line - noggin143_? | 11:42 |
| Xi0s | while we have plans to support non-web federation, there is no fully versed solution for this (other than X509 certs, which I don't think is the future there) | 11:42 |
| oneswig | Do you use levels of assurance in your user/role mappings? | 11:43 |
| Xi0s | ldap-facade is also around, but basically there is no clientless solution that does not expose credentials to the "service" | 11:43 |
| Xi0s | LoA is not something we use, because we don't have any way of passing that kind of data to the service as yet | 11:44 |
| Xi0s | and realistically, unless the service can respond dynamically to the LoA there's no benefit to passing it as a number, though storing it is good for internal audit purposes | 11:44 |
| *** liuyulong has quit IRC | 11:44 | |
| oneswig | Do you also manage posix user ids as part of this service? | 11:44 |
| Xi0s | yes, the identity service manages all of those within a set range | 11:45 |
| oneswig | nice :-) | 11:45 |
| Xi0s | another challenge we are about to face is how we integrate the userID mapping of a service like Lustre in a sensible fashion | 11:46 |
| janders | I was about to ask about exactly that... | 11:46 |
| janders | do you use manila? | 11:46 |
| Xi0s | despite multiple meetings on the topic, i still have yet to gain clarity on how best to manage that | 11:46 |
| Xi0s | not something we've explored yet - we're in discussions to have a test-deployment of a 'secure lustre' so we can see how to get things flowing right | 11:47 |
| verdurin | janders: that's still to be decided | 11:47 |
| Xi0s | personally, I dont see how kerberos tickets dont just solve the problem out of the box, and why an ID translation service is required | 11:48 |
| janders | cool! | 11:48 |
| oneswig | Xi0s: verdurin: have you seen the work of daveholland and team on Lustre/OpenStack integration: http://bit.ly/2stawpN | 11:48 |
| Xi0s | but that could still be my naivety about lustre still | 11:48 |
| verdurin | oneswig: yes, I've seen several iterations of their talk | 11:49 |
| oneswig | thought so... | 11:49 |
| verdurin | One of the reasons why we're looking at Lustre now | 11:49 |
| oneswig | Do we have more questions for Xi0s? | 11:50 |
| oneswig | Is your configuration documented in more detail than the presentation? | 11:50 |
| oneswig | How would you suggest other people replicate your work? | 11:51 |
| daveholland | what user feedback have you had so far? (usability, reliability, features, ...) | 11:51 |
| *** bobh has joined #openstack-meeting | 11:51 | |
| Xi0s | very little so far, we're in a horrible transition world right now where we're running the new auth in parallel with our existing auth for the batch HPC, so i dare say if I was to poll now, feedback would be pretty poor | 11:52 |
| Xi0s | if you wanted to replicate, we're not in a position to share a playbook just yet, but hopefully one day that could be of value | 11:53 |
| daveholland | understood :) I would be interesting in seeing configuration too | 11:53 |
| oneswig | Thanks Xi0s, I hope you'll keep us updated if you do get to publish more information | 11:53 |
| Xi0s | Sure thing | 11:54 |

| *** yamamoto has joined #openstack-meeting | 11:55 | |
| oneswig | For a couple of years SIG members have successfully run a BoF at Supercomputing in the US | 11:55 |
| oneswig | There was a suggestion that something similar ought to be done for ISC (in Frankfurt). | 11:55 |
| oneswig | I don't think that can be decided now, (there's about a month before the submission deadline) | 11:55 |
| *** bobh has quit IRC | 11:56 | |
| oneswig | I'm interested to know if any SIG members attend? | 11:56 |
| janders | I'd give it about 30% probability at the moment. Will see what's the interest in the team though | 11:56 |
| daveholland | We sometimes send someone, no decision yet for this year though | 11:57 |
| oneswig | I am aware of a few others who usually go. If there's enough to run a BoF, I'll ask around | 11:57 |
| verdurin | I'm closer to going than I have been. | 11:58 |
| oneswig | verdurin: do you go to ISC? | 11:58 |

| *** openstack changes topic to "AOB (Meeting topic: scientific-sig)" | 11:59 | |
| oneswig | We are practically on the hour but anything to raise? | 11:59 |
| janders | I wonder if you have any observations of RDMA latency fluctutations for small message sizes. Was playing with SRIOV/IB a bit again. Next week? | 12:00 |
| janders | I should have some decent benchmarks by then | 12:00 |
| oneswig | janders: I'd be interested to hear more on that. I have an old blog post on bandwidth but didn't cover latency. | 12:00 |
| janders | great! | 12:00 |
| janders | I mostly focused on bandwidth till now, too | 12:00 |
| oneswig | Let's get it onto the agenda, thanks janders | 12:00 |
| janders | ok! let's chat more on that next week | 12:00 |

| jungleboyj | We are now past milestone 2 so no more driver merges and we should have all the specs merged. | 16:03 |
| jungleboyj | One exception is for the encryption spec given that we are still waiting on core review of that I believe. | 16:03 |
| eharney | https://review.openstack.org/#/c/621465/ still has review priority set and is close? | 16:04 |
| jungleboyj | LisaLi commented but we were waiting for eharney to also respond. | 16:04 |
| *** walshh_ has joined #openstack-meeting | 16:04 | |
| jungleboyj | eharney: That is a separate discussion we will get to later. | 16:04 |
| eharney | ok | 16:04 |
| jungleboyj | eharney: Can you take a look at the volume encryption spec and see if your concerns have been addressed? | 16:05 |

| jungleboyj | Beuhler ... ... Beuhler ? | 16:12 |
| rosmaita | how do you mean? | 16:13 |
| jungleboyj | If anyone else has asked if they can attend. | 16:13 |
| jungleboyj | Anyway, it looks like we have the attendance list. | 16:14 |

| jungleboyj | If anyone wants to join us at the meetup, please sign up and add your name to the list. | 16:15 |
| jungleboyj | Then we can coordinate getting there. | 16:16 |
| jungleboyj | rosmaita: smcginnis eharney hemna Would you guys like to also do the one on Tuesday night or should we do our own thing? | 16:16 |
| eharney | i haven't looked at any of this stuff | 16:16 |
| smcginnis | The Tuesday night one looks potentially more interesting to me. But I would also be fine just going out for a beer with folks too. | 16:17 |
| jungleboyj | eharney: Ok, take a look and update the etherpad. | 16:17 |
| jungleboyj | smcginnis: I had that thought too. | 16:17 |

| jungleboyj | #topic May can consider leverage hardware accelerator in image conversion before uploading and after downloading | 16:21 |
| *** openstack changes topic to "May can consider leverage hardware accelerator in image conversion before uploading and after downloading (Meeting topic: cinder)" | 16:21 | |
| jungleboyj | LiangFang: Are you here? | 16:21 |
| LiangFang | yes | 16:21 |
| jungleboyj | The floor is your's. | 16:21 |
| LiangFang | currently the new server platform may containing compression hardware accelerator | 16:21 |
| jungleboyj | Right. | 16:22 |
| LiangFang | so we may can leverage such kind of hardware to do the image conversion | 16:22 |
| LiangFang | in order to do this, we may need to introduce new format of image, such as zip | 16:22 |
| eharney | what does the hardware do exactly? | 16:22 |
| LiangFang | e.g. | 16:23 |
| LiangFang | currently if upload volume to image | 16:23 |
| LiangFang | cpu do the format change, from raw to qcow2, for example | 16:24 |
| LiangFang | at this time, the server cpu is highly used, and the response is slow for other user | 16:24 |
| *** pcaruana has quit IRC | 16:25 | |
| jungleboyj | So you are thinking that the image conversion could be offloaded to the specialized hardware? | 16:25 |
| LiangFang | yes | 16:25 |
| LiangFang | if the hardware is there, then use it | 16:25 |
| smcginnis | LiangFang: Do you have a proposed change for this? Or just asking if it makes sense to pursue something like this? | 16:25 |
| eharney | but only for certain image formats, which maybe aren't used currently? | 16:25 |
| LiangFang | smcginnis: I want to do this, here ask your opinion | 16:26 |
| jungleboyj | It is interesting and also has impacts to RSD applications. | 16:26 |
| LiangFang | eharney: yes, the format should be some standard compression format, such as zip | 16:27 |
| smcginnis | In general, taking advantage of FPGAs sounds great. I guess I would have to understand better how that would be implemented though. | 16:27 |
| jungleboyj | smcginnis: ++ | 16:27 |
| LiangFang | I there's no objection here, I will go ahead to prepare spec | 16:27 |
| LiangFang | if | 16:27 |
| jungleboyj | Could picture this being interesting to telco where they are moving images to edge sights. May have FPGAs there that could then be used to speed image expansion. | 16:28 |
| jungleboyj | LiangFang: I think there is a lot to consider and a spec would be the best place to start. | 16:28 |
| LiangFang | yes, so I will prepare spec | 16:28 |
| jungleboyj | Anyone have an objection to that approach? | 16:29 |
| eharney | would need more details to have an objection :) | 16:29 |
| jungleboyj | eharney: :-) | 16:29 |
| rosmaita | eharney: ++ | 16:29 |
| jungleboyj | Ok, so it sounds like it is worth your time to propose the spec with additional details. | 16:29 |
| jungleboyj | LiangFang: ^ | 16:29 |
| LiangFang | ok ok | 16:29 |
| jungleboyj | #action LiangFang to write a spec proposing the functionality. | 16:30 |

| jungleboyj | whoami-rajat: Your turn. | 16:31 |
| jungleboyj | whoami-rajat: Did we lose you? | 16:32 |
| whoami-rajat | So recently a lot of gate failures occurred and one of the most common was testing the eventlet.tpool thread list. I've listed my findings about what might have been caused in the bug. | 16:32 |
| whoami-rajat | jungleboyj: no no, just typing :) | 16:32 |
| jungleboyj | Ok. Cool. | 16:32 |
| whoami-rajat | any feedback on the bug is appreciated. | 16:33 |
| smcginnis | Based on the notes in the bug report, sounds like those unit tests should probably just be removed. | 16:33 |

| geguileo | I am here | 16:34 |
| jungleboyj | Yay! | 16:35 |
| geguileo | sorry, I wasn't paying attention :-( | 16:35 |
| jungleboyj | Thoughts? | 16:35 |
| jungleboyj | #link https://bugs.launchpad.net/cinder/+bug/1811663 | 16:35 |
| openstack | Launchpad bug 1811663 in Cinder "Gate failure : AssertionError: Lists differ: [] != [<Thread(tpool_thread_0, started daemon 14[1123 chars]56)>]" [Undecided,In progress] - Assigned to Rajat Dhasmana (whoami-rajat) | 16:35 |
| *** LiangFang has quit IRC | 16:36 | |
| jungleboyj | It appears that removing the test for now is the appropriate first step. | 16:36 |
| geguileo | could be related to https://review.openstack.org/#/c/630971/ | 16:37 |
| geguileo | But I'd have to read more carefully the bug | 16:37 |
| geguileo | Sorry, not that one | 16:37 |
| geguileo | XD | 16:37 |
| geguileo | https://review.openstack.org/#/c/615934/ | 16:37 |
| geguileo | ^ that one | 16:37 |
| eharney | we could just modify the test to assert that the pool is at least X big, instead of exactly X, right? | 16:38 |
| jungleboyj | #link https://review.openstack.org/#/c/615934/ | 16:38 |
| jungleboyj | eharney: That could work too. | 16:38 |
| e0ne | smcginnis: I thinks we should fix these tests instead of removing them | 16:38 |
| smcginnis | eharney: Not sure if that would work if it was already initialized with a smaller number though. | 16:38 |
| e0ne | eharney: we can just mock all tpool calls in these tests | 16:38 |
| geguileo | it could be that we are not clearing the threads between tests... | 16:39 |
| whoami-rajat | eharney: i think it's not caused by the size rather than the list of threads getting started by some other test. | 16:39 |
| e0ne | geguileo: +1 | 16:39 |
| smcginnis | But if we have concurrent tests running, we would still have this issue even if the threads were cleared, right? | 16:40 |
| whoami-rajat | geguileo: it would still be a task to find the tests triggering the threads to start as the tpool.execute method exists in multiple places in code. | 16:40 |
| e0ne | smcginnis: do we use threads in tests? we should use processes for concurrent run | 16:41 |
| davidsha | smcginnis: are the threads mocked out in the unit tests? | 16:41 |
| whoami-rajat | smcginnis: +1. The async backup tests failing being the example. | 16:41 |
| *** ekcs has joined #openstack-meeting | 16:41 | |
| smcginnis | e0ne: Not sure how that is handled in tox. | 16:41 |
| smcginnis | davidsha: I'm not sure if they are everywhere. | 16:42 |
| *** macza has joined #openstack-meeting | 16:42 | |
| geguileo | looks like somebody removed code from cinder/test.py | 16:42 |
| geguileo | and that broke it | 16:42 |
| jungleboyj | geguileo: What was that? | 16:42 |
| * geguileo probably wrong, I'll look more carefully at the issue | 16:42 | |
| davidsha | smcginnis: kk, you could try purging whatever package you're using for threads and see which tests throw the error? | 16:42 |
| jungleboyj | Ok, geguileo So you will work with whoami-rajat on this? | 16:43 |
| eharney | setUp() in test.py does do a tpool.killall to try to start clean for each run | 16:43 |
| geguileo | eharney: but maybe eventlet has changed the code and now they don't do what they used to? r:-?? | 16:44 |
| davidsha | anything not mocked would show up. | 16:44 |
| geguileo | because I added that in there when I introduced the tests | 16:44 |
| jungleboyj | Ok. We have other topics we should get to. If you could help look into this geguileo it would be appreciated. | 16:45 |

| jungleboyj | #topic follow-up on "remove policy checks at DB layer?" from 5 December meeting | 16:47 |
| *** openstack changes topic to "follow-up on "remove policy checks at DB layer?" from 5 December meeting (Meeting topic: cinder)" | 16:47 | |
| jungleboyj | rosmaita: Your turn. | 16:47 |
| rosmaita | this will be fast | 16:47 |
| rosmaita | the quick recap is that our DB layer policy checks were making it difficult to do a commonly requested policy configuration (to have a read-only admin) | 16:47 |
| rosmaita | we decided that since there are so many of these checks currently in there, it would be too destabilizing to mess with them until we have more tests in place | 16:48 |
| rosmaita | plus, there *is* a way to do this via the policy configuration file, *and* the workaround is valid into all the stable branches (and beyond) | 16:48 |
| rosmaita | so i wrote up a "howto" for the cinder docs and revised it after i got some feedback from lbragstad | 16:48 |
| rosmaita | it's available for your reviewing pleasure: https://review.openstack.org/#/c/624424/ | 16:48 |
| *** hongbin has quit IRC | 16:48 | |
| rosmaita | should be a pretty quick read, just explains some concepts and then walks through how to configure the policy file | 16:48 |
| rosmaita | that's all i got | 16:49 |
| jungleboyj | #link https://review.openstack.org/#/c/624424/ | 16:49 |
| jungleboyj | rosmaita: Ok. Thank you. | 16:49 |

| jungleboyj | The driver has missed the official deadline for inclusion. | 16:51 |
| jungleboyj | They have continued to work on resolving the issues. | 16:51 |
| jungleboyj | Getting a little closer each day. | 16:51 |
| jungleboyj | We need to decide how to proceed. | 16:51 |
| smcginnis | Still code issues being found as recently as yesteday. | 16:51 |
| smcginnis | Last third party CI run failed. | 16:52 |
| jungleboyj | smcginnis: Yeah, that is concerning. | 16:52 |
| jungleboyj | They are down to 7 tests failing. | 16:52 |
| *** ttsiouts has quit IRC | 16:52 | |
| jungleboyj | #link http://52.27.155.124/cinder/rsd/621465/31/testr_result.html.gz | 16:52 |
| smcginnis | I would say with the state it's in now and how far we are past the driver freeze, it's missed stein. | 16:53 |
| smcginnis | It would be one thing if there was a small issue that got resolved in a day or two after the deadline. | 16:53 |
| davidsha | These are issues in the backend rather than the driver, we've been engaging with the backend team to help resolve these. | 16:53 |
| smcginnis | But it still doesn't appear ready. | 16:53 |
| jungleboyj | So these are problems being found in the storage itself? | 16:54 |
| davidsha | Yup | 16:54 |
| jungleboyj | eharney: e0ne_ Other core team thoughts here? | 16:55 |
| davidsha | It's still being worked atm and we're providing the feedback from the CI to the backend team to help resolve it. | 16:55 |
| jungleboyj | If the backend itself is having issues it seems it needs some more burn-in time and could merge as soon as Train opens if things get resolved. | 16:56 |
| e0ne_ | if backend itself is non-stable and deadline is missed I recommend to move it to T release | 16:56 |
| jungleboyj | eharney: You brought the topic up first. | 16:56 |
| smcginnis | There's nothing preventing this driver being available out of tree for Stein users, then added in the Stein release. | 16:57 |
| eharney | yeah, was asking about it because i was just reviewing it and noticed it was about done | 16:57 |
| jungleboyj | smcginnis: You mean Train release? | 16:58 |
| e0ne_ | smcginnis: +1 | 16:58 |
| davidsha | We have the backend team working on a patch we think might address the last 7 issues, it should be redeployed by COB tomorrow. | 16:58 |
| jungleboyj | I think that we should defer acceptance. The patch will be out there for people to pull it down to use out of tree and we can merge in Train once we have seen the CI running stably for a while. | 16:59 |
| jungleboyj | It is consistent with what we have done for other drivers in the past. | 17:00 |
| smcginnis | I think the driver will be a great addition. But we are past the deadline and we've enforced that in the past and made other new drivers adhere to it. | 17:00 |
| jungleboyj | smcginnis: ++ | 17:00 |
| jungleboyj | Ok. We are out of time. If we need to further discuss we can do it in the cinder channel. | 17:01 |

| SotK | oauth 3.0.0 is breaking things and we need to solve that | 19:06 |
| SotK | thanks fungi for starting to look at it | 19:06 |
| diablo_rojo | I think I saw a patch from fungi? | 19:06 |
| * diablo_rojo goes to double check | 19:06 | |
| SotK | yup! | 19:06 |
| SotK | I think its a work in progress though | 19:06 |
| diablo_rojo | FOr now we just pinned the version to be less than 3.0.0 | 19:06 |
| fungi | yeah, the patch from me is just to be able to recreate the errors so we can work on squashing them | 19:07 |
| diablo_rojo | #link https://review.openstack.org/#/c/631260/ WIP | 19:07 |
| fungi | looks like there are several basic test failures in there, a couple of which might be interrelated | 19:07 |
| diablo_rojo | Yeah I think the one I saw in unit tests wasn't the one you were hitting, but it was still related to OAuth | 19:08 |
| fungi | one of them is actually | 19:08 |
| fungi | the story i opened quotes the version from the test failure | 19:08 |
| fungi | just for consistency and ease of investigation | 19:09 |
| diablo_rojo | Got a story link? | 19:09 |
| fungi | but it's the same exception i saw in production (well, on a new dev server deployment at least) | 19:09 |
| fungi | #link https://storyboard.openstack.org/#!/story/2004789 InvalidRedirectURIError with oauthlib 3.0.0 | 19:10 |
| diablo_rojo | Thanks! | 19:10 |
| fungi | figured that gives us a better place to collaborate, and possibly to point a github issue/pr at if we determine it's a legit oauthlib regression and not just us doing things wrong | 19:10 |
| diablo_rojo | good thinking | 19:11 |
| SotK | yep, good idea | 19:11 |
| fungi | the good news is that now https://storyboard-dev.openstack.org/ is being served from a server named storyboard-dev01.opendev.org (note the different domain name for the machine) running ubuntu xenial | 19:13 |
| diablo_rojo | That's super awesome :) | 19:13 |
| fungi | once i figured out the oauthlib problem, that was the last blocker | 19:13 |
| SotK | nice! | 19:13 |
| fungi | so i can now proceed with the database move on storyboard-dev and confirm that's happy | 19:14 |
| diablo_rojo | That's exciting :) | 19:14 |
| fungi | oh, actually we're also getting an error emitted from puppet about characterset collation settings for the db, which i need to dig into first i suppose | 19:14 |
| fungi | but it doesn't seem to be causing any actual service issues | 19:14 |
| fungi | may affect raw query result ordering/sorting from sql | 19:15 |
| diablo_rojo | Interesting | 19:16 |
| fungi | i doubt it's an issue with the migrations, probably just with one of the db configuration parameters we're setting in the puppet manifest | 19:16 |
| *** gouthamr_ has joined #openstack-meeting | 19:16 | |
| fungi | but i need to reacquaint myself with the error details since i was focused more on the openid auth problem | 19:17 |
| diablo_rojo | That's fair. Still making good progress it sounds like :) | 19:18 |
| *** brault has quit IRC | 19:18 | |
| SotK | indeed, thanks for working on all these things :) | 19:18 |
| diablo_rojo | I can try to look into the OAuth failures a little more to see whats up there. | 19:19 |
| fungi | thanks, one is just an http response code mismatch between 400 vs 401 | 19:20 |
| diablo_rojo | Yeah I was gonna start with the easy stuff first :) | 19:20 |
| fungi | that one is likely easy to fix. definitely take a look at the oauthlib changelog though | 19:20 |
| *** efried has joined #openstack-meeting | 19:21 | |
| fungi | #link https://github.com/oauthlib/oauthlib/blob/master/CHANGELOG.rst oauthlib changelog | 19:21 |
| diablo_rojo | Yeah that was going to be my starting point. Thanks for the link again! | 19:21 |
| fungi | also the flowchart and explanation in rfc 6749 are a good reference to explain how that stuff is supposed to work | 19:22 |
| diablo_rojo | Noted | 19:22 |

| SotK | #topic In Progress Work | 19:25 |
| *** openstack changes topic to "In Progress Work (Meeting topic: storyboard)" | 19:25 | |
| fungi | note the oauthlib story isn't not urgent, just worth supporting latest oauthlib eventually | 19:25 |
| fungi | er, is not urgent | 19:26 |
| SotK | diablo_rojo: thanks for the reviews and merges | 19:27 |
| diablo_rojo | My pleasure :) | 19:27 |
| SotK | and sorry I've not done any myself again | 19:27 |

| diablo_rojo | I know I have a few patches out there that need attention | 19:33 |
| diablo_rojo | I probably shouldn't approve my own ;) | 19:33 |
| SotK | probably not :) | 19:33 |
| * SotK sticks a "DO CODE REVIEW" post-it above his screen | 19:33 | |
| SotK | does anyone have anything else to discuss or shall we end the meeting? | 19:36 |

| tdasilva | hi | 21:01 |
| notmyname | welcome | 21:02 |
| notmyname | two quick logistical points to address before we get intot he main meeting topic | 21:02 |
| notmyname | first, FYI, I'll be tagging the stable branches soon. I know I've been saying that, but the last patch just landed, and I realized that I need to do changelog updates. so I'll get that done asap (but it may be while I'm on a plane this weekend | 21:03 |
| mattoliverau | well you'll have a long enough flight :) | 21:04 |
| clayg | hahaha! | 21:04 |
| notmyname | second, I'll be traveling for the next two weeks (LCA next week and holiday the week after), so for the next two meetings, it's up to the rest of you to figure out if there is a meeting and who's leading it | 21:04 |
| mattoliverau | if it makes you feel better, I'll be flying much longer this weekend :P | 21:04 |
| clayg | 👃 👈 | 21:04 |
| notmyname | mattoliverau: it doesn't ;-) | 21:04 |
| mattoliverau | lol | 21:04 |
| clayg | Hahah | 21:04 |
| *** igordc has joined #openstack-meeting | 21:05 | |
| notmyname | any questions or comments about those two things? | 21:05 |
| *** lpetrut has quit IRC | 21:05 | |
| notmyname | ok, no questions, let's move on | 21:05 |
| notmyname | #topic Reconstructor can rebuild to too many primaries | 21:05 |
| *** openstack changes topic to "Reconstructor can rebuild to too many primaries (Meeting topic: swift)" | 21:05 | |
| notmyname | https://review.openstack.org/#/c/629056 has been proposed by clayg, and he'd like to discuss it this week | 21:05 |
| patchbot | patch 629056 - swift - NEED HELP: Rebuild frags for unmounted disks - 3 patch sets | 21:06 |
| *** jamesmcarthur has quit IRC | 21:06 | |
| notmyname | clayg: you've got the floor. | 21:06 |
| clayg | it's related to https://bugs.launchpad.net/swift/+bug/1510342 | 21:06 |
| openstack | Launchpad bug 1510342 in OpenStack Object Storage (swift) "Reconstructor does not restore a fragment to a handoff node" [Medium,Confirmed] | 21:06 |
| clayg | which maybe some people have been aware of... | 21:06 |
| clayg | basically our EC design doesn't support fail-in-place (i.e. unmount a primary disk and worry about ring changes later) | 21:06 |
| clayg | replication does support this strategy for dealing with disk failure and it's been pointed out for awhile that difference is maybe annoying or frustrating or confusing for operators... | 21:07 |
| clayg | for awhile it seemed like there was other more important stuff to work on with improving EC - but eventually we fixed that stuff :D | 21:07 |
| notmyname | "we ran out of easier stuff to fix" | 21:07 |
| clayg | I got to thinking about it and couldn't really come up with a good excuse NOT to do this - so I started to look at if that was worth doing and decided it might be pretty good! | 21:07 |
| clayg | Does anyone have any questions about the bug or priority before I talk about implementation/design challanges that I'd like some help with before I continue coding on it? | 21:08 |
| *** radeks has quit IRC | 21:08 | |
| *** jamesmcarthur has joined #openstack-meeting | 21:08 | |
| kota_ | the challenge sounds so nice | 21:08 |
| clayg | ok, great! so assuming we're onboard with maybe it's worth spending some braincells on it... | 21:09 |
| clayg | (rledisez i know you do EC rebuild sorta different? you may have some different perspective here?) | 21:09 |
| clayg | one issue that was interesting is I had to "index" handoff nodes | 21:10 |
| clayg | we don't want two unmounted causing partner nodes to try and rebuild different fragments to the first handoff | 21:10 |
| notmyname | how'd you do that? enumerate handoffs and assign them frag indexes based on a MOD or something? | 21:11 |
| clayg | so instead if node index 0 is unmounted node index -1 and 1 will rebuild to first handoff, index 1 rebuilds to "second" handoff etc | 21:11 |
| clayg | notmyname: exactly right - minor change in ring code - but it worked out fine... biggest issue seems to be finding all our "fake ring" implementations and teaching them to assign index to handoffs | 21:12 |
| clayg | that part is just worth knowing - i think it's fine | 21:12 |
| notmyname | kk | 21:12 |
| clayg | my challange right now is that the "current" design for primary suffix syncing is... bananas | 21:12 |
| clayg | go look t this code please -> https://review.openstack.org/#/c/629056/3/swift/obj/reconstructor.py | 21:12 |
| patchbot | patch 629056 - swift - NEED HELP: Rebuild frags for unmounted disks - 3 patch sets | 21:12 |
| zaitcev | I'm too scared to look. | 21:13 |
| clayg | when we tell a primary to check it's left and right hand partners we stuff that in job['sync_to'] - a list of two nodes then we ... extend the list of nodes we check... with ALL the other nodes!? | 21:13 |
| clayg | so the idea is that if our partners respond OK, we're done - but if there's *ANY* kind of error (timeout, rejected for concurrency, or even 507) we'll keep going until we do 2 successful syncs ... or run out of primaries to try | 21:14 |
| clayg | that's not right... I think me or paul was just like... we have to do SOMETHING on failure - this can't be "wrong" although it's probably not optimal | 21:14 |
| clayg | then it sat like that for... whatever 3-4 years? | 21:15 |
| clayg | Now that I'm changing it so that if our left partner responds unmounted we'll actually sync to a handoff instead - it seems like *just* doing our left and right partner might be sufficient!? | 21:15 |
| clayg | or maybe we could also check with maybe one more "partner" like maybe on the other side of the ring? then we have a total of three nodes checking on every given fragment... | 21:16 |
| clayg | 3 is still < ALL OF THEM so I guess I was leaning that way | 21:16 |
| clayg | but I could see arguments being made for all kinds of other ideas | 21:16 |
| clayg | so I was hoping we could have some of that debate now - instead of after I wrote it | 21:16 |
| clayg | Anyone have an opinons/ideas/concerns/questions (that's kinda all I got) | 21:16 |
| notmyname | good summary, thanks | 21:17 |
| notmyname | and it sounds like a hard problem | 21:17 |
| notmyname | if the fragment handoff is MOD the fragment index, doesn't that mean that you "only" need to check every N+M nodes, not all of them? eg with 8+4, you only need to check every 12th one (+frag_index)? hmm, but that means handoffs likely wouldn't be found after a rebalance | 21:17 |
| notmyname | clayg: there's a step you described that I could use more detail on | 21:18 |
| *** priteau has joined #openstack-meeting | 21:18 | |
| clayg | i don't know that putting frags further out in the handoff chain makes them any more or less likely to be reachable in the handoff chain after a rebalance | 21:18 |
| notmyname | Now that I'm changing it so that if our left partner responds unmounted we'll actually sync to a handoff instead - it seems like *just* doing our left and right partner might be sufficient!?" | 21:18 |
| notmyname | good point re handoffs. it's randomish rebalancing anyway | 21:19 |
| notmyname | clayg: can you explain the "just doing our left and right partner" part? what is "doing" in this case? | 21:19 |
| clayg | yes... the big change is that if we get a 507 specifically when syncing with a partner node we'll rebuild/sync to a handoff (and keep the handoff in-sync as long as it's mirroed primary is unmounted until a ring change) | 21:19 |
| *** ganso has quit IRC | 21:20 | |
| mattoliverau | Sounds good.. but to be honest, I'd need to go read the code and think on it. I might be a little jetlagged and may also may have had a few beers with dinner as I forgot about this meeting. | 21:21 |
| clayg | "doing" means making sure that A SET of our left partners frags are rebuild *somewhere* - either on the primary where it belongs, or if it's unmounted we'll actively find another node and rebuild fragments there... that's what enables fail-in-place | 21:21 |
| *** TxGirlGeek has quit IRC | 21:21 | |
| notmyname | so after a rebalance, the handoff frag will attempt to put to the primary, which may still be unmounted. then the primary neighbor will choose a new handoff location which will again be kept in sync until a rebalance? sounds like a risk for "replication bumbs" | 21:22 |
| clayg | mattoliverau: right... it'd be nice if we could go over something like this around a white board. Except I'd not like a TON of work regardless of what we decide - and we could change it later - so I was hoping to have a direction settled in the next week or so and code it up for review with a couple of weeks tops | 21:22 |
| clayg | notmyname: with a fail-in-place strategy you *remove* unmounted drives from the ring before rebalance | 21:23 |
| clayg | notmyname: also, with EC after a rebalance you almost certainly should be in handoffs_only mode (no rebuilds) until you finish shuffling data around | 21:23 |
| notmyname | I like that second point. not sure I agree with the first | 21:24 |
| clayg | so... those handoff nodes with the rebuild fragments will *probably* be the guy that ships the frags to their new primary | 21:24 |
| notmyname | yeah, that makes sense | 21:24 |
| *** priteau has quit IRC | 21:25 | |
| clayg | notmyname: there is zero value in having a "dead" drive in the ring... you might leave the failed drive unmounted in the chassis - but having it assigned parts is kinda mad | 21:25 |
| *** cloudrancher has joined #openstack-meeting | 21:25 | |
| notmyname | so with replicas, drive fails and gets 507s internally and swift works around it. if you remove it from the ring, things get faster, but leaving it doesn't stop any durability things. and with EC you're *required* to remove dead drives before rebalance? | 21:25 |
| *** ralonsoh has quit IRC | 21:26 | |
| clayg | yeah... so the closest thing i can think of we have to a "durability config option" is handoffs_delete | 21:26 |
| notmyname | if that's true, I'm not sure it's bad, but I just want to make sure I clearly understand :-) | 21:26 |
| clayg | so i'm not sure having "reconstructor extra sync nodes" option is a good idea - and I'm leaning towards 3... but it's a bit different than what we're doing now... and I don't think what we're doing now is very smart | 21:27 |

| clayg | uhh... no i don't guess you're "required" to remove dead drives... but I guess I hadn't considered throughly what happens if you DON'T because it seemed odd not to | 21:28 |
| notmyname | gut-reaction, it seems like more "special knowledge" that should be more built-in. makes the "how to run swift" question harder (and it's already hard). | 21:29 |
| clayg | on replicated - yes any part-replicas still assigned to the unmounted drive (which could change but also might be largely the same) would have to be re-replicated to a new handoff | 21:29 |
| notmyname | or rather, I wonder what sort of automation could be more built in (eg only running handoffs-only for ec policies after a rebalance) | 21:29 |
| clayg | the handoff from the last ring will try to sync back to the primaries... and might fail to reap unless you have handoffs_delete set to two | 21:30 |

| rledisez | notmyname: on that last point, we do that by distributing the builder (it's dirty, but efficient): https://review.openstack.org/#/c/389676/ | 21:30 |
| patchbot | patch 389676 - swift - WIP: reconstructor: do not sync recently moved parts - 2 patch sets | 21:30 |
| clayg | yeah having to manage your ec rebalance modes is super annoying 😡 | 21:30 |
| *** jamesmcarthur has quit IRC | 21:30 | |
| *** a-pugachev has quit IRC | 21:31 | |
| notmyname | I think my questions/comments/thoughts are a bit of a slight distraction from your original question. you're basically asking if the proposed strategy has obvious correctness issues | 21:31 |
| *** jamesmcarthur has joined #openstack-meeting | 21:32 | |
| *** jamesmcarthur has quit IRC | 21:32 | |
| clayg | well, I don't think it has "obvious correctness" issues - I think the existing code is "obviously superfluous" - i was hoping maybe we might agree "yeah that code should change, go ahead" and then if I'm lucky I'd hear "yeah 3 nodes checking on each frag is probably about right" or "shouldn't it work like XYZ" | 21:33 |
| *** macza has joined #openstack-meeting | 21:33 | |
| notmyname | to the correctness question, as long as neighboring fragments are in different durability zones, then it's probably fine. (right?) for example, you don't want a rack to fail and then have a big enough gap in the available frag set so that they gap doesn't get reconstructed | 21:33 |
| clayg | so handoffs go out of their way to bounce around failure domains - but I can't say for sure there wouldn't be a bad sequence for any given part of any given ring - we're just not that regimented in how we structure handoff sequences - and skipping around the handoffs via modulo might exacerbate the issue for a given frag_index in a given part | 21:35 |
| clayg | but I definitely don't have a better idea there | 21:35 |
| notmyname | that makes sense for handoffs. not sure we can do any better there (and choosing something modulo or random likely won't be any better than neighbors) | 21:35 |
| clayg | ... and even imagining failure domain distribution is imperfect - having a copy of the frag rebuild in ANY failure domain is better than not having the fragment because you're using fail-in-place and didn't know about lp bug #1510342 | 21:35 |
| openstack | Launchpad bug 1510342 in OpenStack Object Storage (swift) "Reconstructor does not restore a fragment to a handoff node" [Medium,Confirmed] https://launchpad.net/bugs/1510342 | 21:35 |
| mattoliverau | Well, disks will fail, and duribiltiy is most important, so yes I agree once we unmount we should do something. We do it in Replication so we should also do it in EC. So I think it's the right move. | 21:36 |
| notmyname | but if frags are only checking neighbors, what if primaries 2, 3, and 4 are down? what does 1 check? what does 5 check? does 3 ever get reconstructed? | 21:36 |
| clayg | @notmyname right - I think that thing (broken chains) is what prompted the weird existing behavior | 21:36 |
| notmyname | existing == check everything? | 21:37 |
| clayg | (yes) | 21:37 |
| *** a-pugachev has joined #openstack-meeting | 21:37 | |
| clayg | 3 is in a tough spot because TWO of the nodes that might check on him are down/unmounted otherwise not checking on him | 21:37 |
| mattoliverau | Getting more nodes from a ring tends to hit the same nodes, so left + right, or L + R + middle sounds good. But seeing as get more nodes should get the same, can't we just use them.. and trust the algorithm to keep them in different domains. | 21:37 |
| clayg | ... so that lead me to maybe we should have *three* nodes check on each frag (i have a picture in my notebook) 😁 | 21:38 |
| clayg | notmyname: also I think you're up-to-speed - you're thinking about the problem I'm worried about - how can I not check everything but still be "good enough" | 21:38 |
| notmyname | clayg: if I understand correctly, then yeah, I like the idea of your 3-way checks. 2 neighbors + one "across" the ring | 21:38 |
| clayg | mattoliverau: yeah I think we can just trust the ring rebalance abstraction from this context until/unless we see a bad behavior (and then we should fix the ring - not the code that's expect it to do it's job) | 21:39 |
| notmyname | and eg with 12 fragments, it's likely good enough without being too expensive. probably should do some mathy things to find the exact numbers | 21:39 |
| clayg | notmyname: right mathy things... kota_ you're good at math!? timburke is too... is he around? | 21:40 |
| notmyname | rledisez: kota_: tdasilva: m_kazuhiro: does all this make sense? | 21:40 |
| clayg | s/all/any of/ | 21:40 |
| notmyname | timburke got sick kids and is on PTO today :-( | 21:40 |
| clayg | we're doomed | 21:40 |
| kota_ | still catching up... now | 21:41 |
| m_kazuhiro | me too | 21:41 |
| mattoliverau | anyway may thoughts are, yup we need to do something. Go make it better. It sounds better then what we have.. well actually a pretty good idea. I'll checkout the code tomorrow and see if I get anymore questions, or bad suggestions ;) | 21:41 |
| rledisez | i *think* i get the idea of the 3-way checks, but I need to think more of it. it's way too complex for my timezone :) | 21:41 |
| notmyname | yeah, that went pretty quickly. I know it's hard to follow fast-moving, technical discussions in your non-native language :-) | 21:41 |
| kota_ | got stomach ache and back here, long logs :P | 21:42 |
| mattoliverau | rledisez: +1 :P | 21:42 |
| clayg | ok good - so maybe this was the sanity check - and I'll keep going - folks can think more about it and maybe next week we'll have something in good shape to discuss... that would work ok with my timelines | 21:43 |
| notmyname | clayg: ok, so assuming kota_ and m_kazuhiro and rledisez and mattoliverau will be able to sleep/wake-up and think more about the code and ideas, did you get answers you can use? | 21:43 |
| notmyname | clayg: good :-) | 21:43 |
| clayg | notmyname: 👍 | 21:43 |
| kota_ | yup | 21:43 |
| m_kazuhiro | ok | 21:43 |
| notmyname | clayg: thanks for working on this. it's a hard problem that's important to solve, and I'm glad you're on it :-) | 21:43 |
| mattoliverau | +1 | 21:43 |
| clayg | no worries | 21:43 |
| notmyname | #topic s3 versioning | 21:43 |
| *** openstack changes topic to "s3 versioning (Meeting topic: swift)" | 21:44 | |
| clayg | zohno, no tim! | 21:44 |
| notmyname | on behalf of tim, I wanted to mention something, but only for "Read this". not to discuss right now | 21:44 |
| notmyname | #link https://gist.github.com/tipabu/4d49516050f6762ce9cf6b2ebb49e545 | 21:44 |
| notmyname | basically, tim is working on getting s3 versioning support. he's run in to a few interesting problems to solve with it. some of which have API implications. so he wrote up that doc to cover the issues and his thoughts on solutions | 21:45 |
| notmyname | I know he'd appreciate people reading over it to understand what's going on so it can be talked about in more detail later | 21:45 |
| notmyname | #topic open discussion | 21:45 |
| *** openstack changes topic to "open discussion (Meeting topic: swift)" | 21:45 | |
| notmyname | any other topics to bring up this week? | 21:46 |
| notmyname | the combined ptg/summit in denver is currently accepting presentation proposals. the deadline is next week | 21:46 |
