hongbin#link https://review.openstack.org/#/c/499534/03:15
mkraiGot feedback from Hongbin on checking the virtualization flag before installing03:15
mkraiSince CC can't run inside VM03:15
mkraii didn't do much last week. I will update the patch this week03:15
mkraithat's all from me. Any questions?03:16
hongbinmkrai: no from me, thanks for the patch to devstack-plugin-container03:16
mkraihongbin: I have one question about gate03:16
hongbinmkrai: go ahead03:16
mkraiwe can't setup a gate for CC if we want because infra sets up devstack inside VM. Right?03:17
hongbinyes, as far as i know, infra CI are all in VM03:17
mkraiOk thanks03:18
hongbinthe only way to setup CC in CI is third-party CI03:18
mkraiwhich is difficult to get I assume03:18
hongbinthat means a spornor needs to contribute the resource for that03:18
spni have the setup to try out03:18
mkraispn: dedicate those hardwares to infra team. do you mean?03:19
mkraiOr just for testing now?03:19

*** openstack changes topic to " (Meeting topic: senlin)"13:02
openstackThe meeting name has been set to 'senlin'13:02
ruijie_here we go ..13:02
longkb_Hi everyone! It nice to meet you guys13:02
ruijie_please feel free to add items to the agenda13:02
ruijie_hi longkb_13:02
ruijie_let's wait for a while :)13:03
*** chenyb4_ has joined #openstack-meeting13:03
ruijie_hi chenyb4_13:03
*** s3wong has joined #openstack-meeting13:04
ruijie_okay, let's get started13:04
ruijie_hi Qiming, we discussed about the extra field/policy to add hook to scaling process13:05
*** hashar_ has joined #openstack-meeting13:06
*** bobh has joined #openstack-meeting13:07
ruijie_so, that policy could contains how to get approved or how to send notifications?13:07
Qimingthere are two sub-topics here13:08
*** hashar has quit IRC13:08
Qimingone is about how to inject something into an API request to indicate whether a request is an "original" one13:08
*** amotoki_ has quit IRC13:09
Qimingthe other one is about how to add hooks (possibly a general policy) that examines this 'something' and decide whether a hook will be triggered13:09
*** toscalix has quit IRC13:09
Qimingwe are supposed to be following the global api-wg guidelines, for api requests and responses13:10
ruijie_by the "original" request, you mean we will send a request or notification to someone, and they will call back?13:10
ruijie_once the "original" comes in, we need to record it somewhere to wait for callback, after that the process could pass to next step?13:13
*** gouthamr has joined #openstack-meeting13:13
*** StefanPaetowJisc has joined #openstack-meeting13:14
Qimingwe don't wait13:15
*** toscalix has joined #openstack-meeting13:15
Qimingthat request has been "processed" and "redirected"13:15
Qimingthese kind of info are have to be either sent in the body or embedded in the header13:17
Qimingif we carry these info in header, it would be something like this: https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS13:18
ruijie_request(with special field) --> create action with special status --> return/call/notify ; callback to trigger that action --> scale in/out13:18
Qimingthe original request doesn't have to be changed13:20
Qimingmost of the time, requests should be processed as usual13:21
Qimingit is only those requests mutated by a third party software that need a special tag13:21
ruijie_okay, Qiming, may need to look forward to it :) thought it a little bit simple13:23
Qimingto get it done in a disciplined way is not straightforward13:24
Qimingalthough get it done in an adhoc way is simple enough13:24
Qimingreference: http://specs.openstack.org/openstack/api-wg/guidelines/headers.html#avoid-proliferating-headers13:25
ruijie_yes Qiming13:25
Qimingalso this: http://specs.openstack.org/openstack/api-wg/guidelines/http.html13:26
Qimingwe are supposed to return a proper status code for this13:26
QimingI don't think we should add an 'extra' field to each and every API request ...13:28
*** alexchadin has quit IRC13:28
Qimingit is gonna be dirty13:28
*** felipemonteiro_ has joined #openstack-meeting13:28
*** felipemonteiro__ has joined #openstack-meeting13:29
*** markvoelker has joined #openstack-meeting13:30
ruijie_thanks Qiming, let's talk about it a little bit later :)13:30
ruijie_another one is about this patch https://review.openstack.org/#/c/504830/13:30
ruijie_to revisit the documentation of event dispatcher13:31
*** ykatabam has quit IRC13:31
ruijie_the developer part of the event dispatcher looks good now?13:31
Qimingyes I think so13:32
*** felipemonteiro_ has quit IRC13:33
Qiminghowever, I think we are supposed to split that rst file into two13:33
Qimingone for user, one for developer13:33
ruijie_this one is about how to extend the event plugin13:34
ruijie_Qiming, you mean we may need to divid the user reference to 2 parts?13:34
Qimingthe contents under 'contributor' subdir are there for developers13:34
Qimingthe one in your patch is targeting users13:35
ruijie_yes Qiming13:35
QimingI see, we already have guide for developers13:35
ruijie_yes Qiming :)13:36
ruijie_next one. the tempest-plugin13:36
ruijie_the patch is already there, will keep checking it13:37
ruijie_that's all from my side :)13:38
ruijie_I noticed longkb_ is here :)13:39
Qimingwe will need to revise some gate jobs later when the github project is migrated13:39
ruijie_yes Qiming, after that, will move the gate jobs from senlin to the plugin step by step13:39
Qimingto be honest, I'm not sure13:40
Qimingthe gate jobs are there to ensure changes to senlin repo won't break anything, they are not there to protect the tempest plugin13:41
Qimingso maybe the jobs are supposed to be revised to invoke tempest plugin project, and they still vote for senlin patches13:41
*** coolsvap has quit IRC13:42
Qimingalso speaking of your event doc improvement13:43
Qimingwhen reading this: https://docs.openstack.org/senlin/latest/user/events.html13:43
QimingI felt that we may need a subsection for the dispatcher configuration so that users will easily find the info13:43
ruijie_one for the database and another for the messaging13:44
Qimingwe need a subsection in that article13:44
Qimingfor readability's purpose13:45
Qimingjust a quick thought13:45
ruijie_okay, that makes sense13:45
*** hoangcx_ has joined #openstack-meeting13:45
ruijie_next one is about the meetup13:46
*** ijw has joined #openstack-meeting13:46
ruijie_we can organize the meetup in Beijing in the 2nd/3rd week of Oct13:47
Qimingany suggestion on the date/location ?13:47
ruijie_how about 15th Oct13:48
ruijie_Queens-1 milestone :)13:49
Qimingit is okay for me13:49
QimingI may have a conflicting schedule but not yet fixed13:49
*** ijw has quit IRC13:50
*** cleong has joined #openstack-meeting13:50
ruijie_the date could be discussed, will send an email to mailing list. I think the location could be Beijing :)13:50

haleybi just rebooted, but remember it ~20%16:04
ihrachyshaleyb, you mentioned in the bug there is still a fix to land16:04

ihrachyscan you post it in LP?16:04
*** dprince has joined #openstack-meeting16:04
haleybyes, it needs a quick re-spin to address a comment16:04
ihrachysI am at loss with all those dvr fixes you have with Swami :)16:04
ihrachyshaleyb, is it required to fix the gate failure?16:05
ihrachysor it's just nice to have?16:05
*** sridharg has quit IRC16:05
haleybit's required to fix the server side, we only worked around it in the agent16:05
ihrachysok. I remember we make the job non-voting. I assume we will get it back after the server side fix?16:06
*** rbowen has quit IRC16:06
haleybi hope so, if the failure rate is still good16:07
ihrachysI recollect we had a revert for that somewhere.16:07
ihrachysbut now I fail to find it16:07
*** rbowen has joined #openstack-meeting16:07
jlibosvaI don't think we do16:07
haleybactually the dvr-multinode job is 0%, it's the regular multinode job that's at 20% failure16:07
*** hashar_ is now known as hashar16:08
jlibosvathis is the original - https://review.openstack.org/#/c/500567/16:08
ihrachysok, I created a revert for tracking purposes16:08
*** Apoorva has joined #openstack-meeting16:08
jlibosvahaleyb: which could also mean we're not collecting data correctly, 0% failure is always suspicious to me as we have infra issues or catching regression failures etc.16:09
ihrachyshaleyb, hm... should we break it back so that we are on the same failure rate? :p16:09
haleybwhat, you don't believe DVR is better? :-p16:09
ihrachysit is. it's just that the base line we compare with was always rather low. :p16:09

ihrachysapi job is at 20% failure rate on 7days sliding window chart16:11
ihrachysnot sure what causes that16:11
ihrachyscould it be the skip_checks issue?16:11
ihrachysI mean this: https://review.openstack.org/#/q/I1c0902e3c06886812029fae0e4435bb6674f57df16:11

*** yushiro has quit IRC16:12
ihrachysI believe we made some significant progress lately with fixing and triaging failures16:13
ihrachysI believe the main issue that is causing 100% failure rate right now is the one where test_trunk_lifecycle fails because ovs agents clean up ports that don't belong to them16:13
openstackLaunchpad bug 1687709 in neutron "fullstack: ovs-agents remove trunk bridges that don't belong to them" [High,In progress] - Assigned to Armando Migliaccio (armando-migliaccio)16:13
ihrachysand armax had a WIP patch for that16:14
ihrachysthe idea there is to introduce a test only option that will set a prefix for agent ports16:15
ihrachysthen configure each fullstack test case with a unique prefix16:15
ihrachysthen ovs agent would filter those ports with the prefix16:15
ihrachysnot ideal, but should be an easy fix16:15
*** dmacpher has joined #openstack-meeting16:15
ihrachysand then we can follow up with filtering them on ovsdb level, or something else16:15
ihrachysjlibosva, with that patch, do we still want to follow up?16:16
jlibosvaI just don't like that we're having "monkey patch hack" at one agent and "config hack" in other agents. I'd rather have it unified16:16
jlibosvaand moving towards removing those hacks longterm but the goal of the idea is neat16:17
ihrachysjlibosva, that's not ideal. but do you agree testing the actual production code is better than monkey patching the agent?16:17
*** dmacpher has quit IRC16:17
jlibosvaimho it's moot16:17
ihrachysmoot point?16:17
ihrachysas in - longterm both are bad?16:18
*** donghao has joined #openstack-meeting16:18
jlibosvano, I mean if you have a code that's parametrized and never used in production - or you patch the code. It's still the same16:18
jlibosvajust written differently16:18
jlibosvabut if we get rid of monkey patching and replacing it with no-prod config values, I'm good. But in my opinion it's the same as monkey patching16:19
*** ad_rien_1 has joined #openstack-meeting16:19
*** ad_rien_ has quit IRC16:20
ihrachysjlibosva, I remember I had complications with monkey patched agents when switching to rootwrap because I needed to configure rootwrap to allow those dirs for exec_dirs16:20
ihrachysof course now it's solved somewhat16:21
ihrachysbut it left bitter taste in my mouth16:21
*** lbrune has joined #openstack-meeting16:21
ihrachysso to the question of follow up - is it smth we want to still track?16:21
ihrachysor we will pretend we can live with the hacks?16:21
jlibosvais it the last issue? I thought we still have some l3 east-west failing IIRC16:21
ihrachysthere are some issues that show once in a while16:22
jlibosvaor you mean to track the isolation stuff that I was working on?16:22
ihrachysI was hoping that we tackle this one to finally have a reasonable chart that is not 100% always16:22
*** donghao has quit IRC16:22
ihrachysand then can meaningfully assess progress16:22
ihrachysbut yes, there are others16:22
jlibosvasounds good16:22
jlibosvabtw the trunk failure shouldn't be 100%, it's a race condition16:22
ihrachysre follow up, I meant the isolation and/or the filtering of ports on ovsdb query level16:22
ihrachyssome decent fix that would allow us to kill the test option16:23
ihrachysjlibosva, sometimes the job rate falls to 95%, yes :p16:23
jlibosvaI'll keep it in my backlog16:23
jlibosvaah, nice :) I like progress16:23
ihrachysok, good. it's a nice thing to have, but I believe not a critical thing right now, especially considering all the other priorities we tend to have16:24
ihrachysanother bug that affected the job was https://bugs.launchpad.net/neutron/+bug/171758216:24
openstackLaunchpad bug 1717582 in neutron "fullstack job failing to create namespace because it's already exists" [Undecided,In progress] - Assigned to Slawek Kaplonski (slaweq)16:24
ihrachysand slaweq has a fix: https://review.openstack.org/#/c/503890/16:24
ihrachysas we learned, netlink is async and hence doesn't provide guarantee that after netns add the namespace is present16:25
ihrachysso we need to spin16:25
*** lbrune has quit IRC16:26
ihrachysI need to get back to the patch, seems like slaweq has reasonable replies to my concerns16:26
jlibosvathomas has ideas how to avoid the race16:27
jlibosvait's in PS616:27
*** bobh has joined #openstack-meeting16:27
*** StefanPaetowJisc has quit IRC16:27
ihrachysok, will check16:27
ihrachys(looking through the list of fullstack bugs) one other thing I had for the suite is switching to using SIGTERM instead of SIGKILL for all services: https://bugs.launchpad.net/neutron/+bug/148754816:28
openstackLaunchpad bug 1487548 in neutron "fullstack infrastructure tears down processes via kill -9" [Low,In progress] - Assigned to Ihar Hrachyshka (ihar-hrachyshka)16:28
*** rwsu has quit IRC16:28
ihrachysI have https://review.openstack.org/#/c/499803/16:28
ihrachysbut I need to rework it so that if SIGTERM doesn't kill in a minute, we SIGKILL16:28

*** julim has joined #openstack-meeting16:32
*** bobh has quit IRC16:32
*** VW_ has quit IRC16:32
ihrachysafaik there were two fronts - one dvr fixes from haleyb and Swami and another router migrations from anilvenkata16:32
jlibosvaI think only Anil has some patches for router migrations16:32
ihrachyswould be nice to have a list of things we believe are related16:32
*** lbrune has joined #openstack-meeting16:32
ihrachysjlibosva, afaiu some dvr fixes for grenade were effectively also helping scenarios16:33

*** ralonsoh has quit IRC16:33
jlibosvacool, two birds with one stone16:33
haleybSwami just sent out https://review.openstack.org/#/c/505324 as well as he noticed there are some edge cases still broken16:33
haleybi think he had opened a new bug for that, will check16:34
ihrachysthe flow of dvr fixes both encourages and scares16:35
ihrachysit's encouraging that we fix that16:35
ihrachysbut... it's like... broken since ever?16:35
*** sshank has joined #openstack-meeting16:35
*** sdague has quit IRC16:35
haleybrouter migrations are complicated.  this is new since the dvr_snat_bound code merged in pike16:35
*** dprince has quit IRC16:35
ihrachysjlibosva, haleyb you think it would make sense to have a list of scenario related fixes somewhere so that we can prioritize them somehow?16:36
jlibosvaI can take an AI to do16:36
*** sdague has joined #openstack-meeting16:36
ihrachys#action jlibosva to prepare a list of scenario related fixes16:36
ihrachysjlibosva, thanks!16:36
haleybyes, either a single bug and/or topic i guess16:36
ihrachyshaleyb, ^ please help Jakub with that, I believe you have a good grasp of dvr side of things16:37
haleybwill do16:37
*** mikal has quit IRC16:37
jlibosvamaybe we could create a short-term LP tag to get the list quickly16:37
ihrachysjlibosva, apart from it, are we aware of any other fixes? how close would the fixes we have in pipeline get us in terms of failure rate?16:37
ihrachysjlibosva, good idea. we can create a new tag, no need to have a permanent one16:38
*** pcaruana has quit IRC16:38
jlibosvathere is a fix for remote security groups that iwamoto is working on16:38
ihrachyshttps://review.openstack.org/#/c/492404/ ?16:39
jlibosvathis should also bring some peace16:39
ihrachysI thought it's just perf optimization?16:39
ihrachysok I see in the commit message: "that filtering16:40
ihrachysare correctly performed"16:40
ihrachysso I guess it's functional too16:40
jlibosvano, it's a new regression caused by conjunctions16:40
*** unicell has quit IRC16:40
jlibosvaalso slaweq has a patch for qos for better logging in the test: https://review.openstack.org/#/c/491244/16:40
ihrachysjlibosva, it affects pike+?16:40
ihrachysI mean the conjunctions16:41
jlibosvait's been merged to pike16:41
ihrachysanother regression, good16:42
ihrachysbut it seems like we are not close to complete there?16:42
ihrachysso I guess I will need to release .1 without it16:42
ihrachysjlibosva, re the qos test patch, my concern was that it hides the issue. is it correct?16:43
ihrachysit retries over and over. shouldn't we expect it to work correctly?16:43
ihrachysinstead it hangs in the middle16:43
jlibosvayep, we could have some mechanism to retry few times16:44
jlibosvabut importantly, it adds some logging messages that could reveal more information about the issue16:44
*** Qiming has quit IRC16:45
ihrachysjlibosva, but can't we raise after logging?16:46
jlibosvawe can :)16:46
ihrachysotherwise it seems like the test will pass if it works after e.g. 5th attempt16:46
jlibosvaor make a loop16:46
jlibosvaI see16:46
ihrachysit can also loop now indefinitely16:47
ihrachysbefore, the timeout would bubble up to test runner16:47
ihrachysnow it's swallowed16:47
jlibosvaI was thinking about trying several times but you're right, that failing the test would make more sense16:47
jlibosvaand we should log the exception too16:47
*** mikal has joined #openstack-meeting16:47

AJaegerlots of open changes in the queue to review...19:04
jeblairmordred is continuing to work on migration script19:04
jeblairmordred: i think it emits actual job output now?19:04
jeblairmordred: do you think we can, say, run some nova check jobs tomorrow or something?19:04

jeblairandreaf wrote a basic native v3 tempest job that builds on the basic native v3 devstack job19:05
jeblairi haven't reviewed that yet, but hope to soon19:05
*** felipemonteiro has joined #openstack-meeting19:05
jeblairthat's in devstack-gate repo (for now; we'll move it to tempest soon)19:05
clarkbis that the first job addition from outside of zuul development?19:05
*** VW has quit IRC19:06

*** StefanPaetowJisc has joined #openstack-meeting19:06
*** felipemonteiro__ has joined #openstack-meeting19:06
jeblairbut having andreaf self-bootstrap into writing a v3 job is awesome :)19:06
* fungi cheers19:06
jeblairtristanC showed us his in-progress dashboard work which will be important once we finish the cutover19:07
jeblair(hopefully we're not far away from having a job history dashboard)19:07
jeblairwe have some ideas of how it and openstack-health can be complementary19:07
jeblairtobias has patches in progress to nodepool to improve quota support19:08
jeblairthat will allow us to use smaller flavors for, say, pep8 jobs19:08
mordredjeblair: yes - there is a giant stack of patches I'll bug people about tomorrow when this migration is done19:08
jeblair(and therefore increase our apparent capacity)19:08
jeblairmordred: awesome!19:08
clarkbfor us to make use of that we may need some quota changes (as we have instance quotas that line up with ram use in most cases)19:09
jeblairclarkb: yeah, but it'll be a good problem to have :)19:09
dmsimardI have a series of patches that should be mostly ready to land as far as multi node in v3 in concerned19:09
*** felipemonteiro has quit IRC19:09
*** cloudrancher has quit IRC19:10
jeblairwe also did a roadmap exercise at the end of the week.  we were exhausted, so it's only in rough etherpad form at this point.  some time this week or next, i'll write it up for further discussion, so we can all get on the same page for what we do between the openstack cutover and v3 release, and what comes after.19:10
dmsimardzuul-jobs has the role bits while the jobs/integration testing is in openstack-zuul-jobs19:10
jeblairdmsimard: great!19:10
dmsimardpabelanger and I discussed that it's worth thinking about when and where we'll want to trigger the base-integration and multinode-integration jobs (filtering on files?)19:10
*** cloudrancher has joined #openstack-meeting19:11
jeblairi need to track down problems with logstash job submission.  that's the only transition blocker (aside from migration script) that i'm aware of19:11
mordredstack of patches related to migration script from me ends with: https://review.openstack.org/#/c/50496819:11
clarkb#link https://review.openstack.org/#/c/504968 Zuulv3 job migration scripting19:11
clarkb#link https://review.openstack.org/#/q/topic:zuulv3-multinode Native zuulv3 multinode jobs19:12
dmsimardOnce the zuulv3-multinode stack has landed, I'll try and see how hard it would be to bring up a native devstack multinode19:12
jeblair#link https://etherpad.openstack.org/p/zuulv3-roadmap rough draft post-cutover roadmap19:12
mordredhrm - I'm going to re-topic migration patches to zuulv3-migration19:12
fungirather than just zuulv3?19:13
clarkb#link https://review.openstack.org/#/q/topic:zuulv3-migration Also for migration scripting19:13
fungioh, right, they're on the feature/zuulv3 branch already19:13
fungiso show up in queries that way19:14
*** slaweq has quit IRC19:14
*** slaweq has joined #openstack-meeting19:14
dmsimardit's probably trivial to filter on topic:^zuulv3.* or something regardless19:14
dmsimardbecause those patches are not necessarily on the zuul repo with feature/v3 branch19:14
dmsimardi.e, project config, zuul jobs, etc19:15
fungii guess i should update my query19:15
jeblairif folks could use 'zuulv3' as the topic for any patch not on a feature/zuulv3 branch, that would be great19:15
jeblairon feature/zuulv3, a topic *other than* zuulv3 is helpful.  :)19:15
clarkb#action everyone use 'zuulv3' as the topic for any patch not on a feature/zuulv3 branch, that would be great. on feature/zuulv3, a topic *other than* zuulv3 is helpful.19:16
dmsimardhmm, at first glance it doesn't seem like it's possible to put a regex for the topic field search :/19:16
jeblair(so mordred's zuulv3-migration here is great)19:16
*** pchavva has quit IRC19:17
mordredjeblair: WELL - except that zuulv3-migration has a bunch of patches on project-config too - it's a tricky little devil19:17
dmsimardoh, gerrit has an 'intopic' search parameter so https://review.openstack.org/#/q/intopic:zuulv3 works19:17
*** Sukhdev has joined #openstack-meeting19:17

clarkb(once through general status updates)19:18
jeblairmordred: did you send out that email?19:19
clarkbhe did19:19
dmsimardhe did :)19:19
*** felipemonteiro__ has quit IRC19:19
jeblairthat probably covers the current plan afaik19:20
mordredk. I've updated the zuulv3-migration topic on project-config patches to just be zuulv319:20
*** felipemonteiro__ has joined #openstack-meeting19:20
clarkbok let me dig up a link for it19:20
*** jlk has joined #openstack-meeting19:20
mordredwell - that plan is "planning on doing a rollout on Monday" - we probably want to have a slightly more detailed infra-team plan19:21

*** m-greene_ has quit IRC19:21
clarkbanything else we want to go over on Zuulv3 related items?19:23
mordredwell - lemme say one more quick thing about migration script19:23
*** felipemonteiro has quit IRC19:24
mordredonce the patches from me in zuul, project-config, openstack-zuul-jobs are landed ...19:24
mordredto my knowledge the migration script is good to go19:24
*** felipemonteiro has joined #openstack-meeting19:24
dmsimardmordred: I'd like to test drive some sanity checks against what I feel is most vulnerable -- deployment projects (openstack-ansible, puppet-openstack, kolla, tripleo, etc)19:24
mordredso it's important to start combing through the generated content for bugs19:24
dmsimardCan I go ahead and "whitelist" those projects in main.yaml and submit what would be their "migrated" jobs as zuul.yaml in their repos ?19:25
Shrewsi second mordred's suggestion. there WILL be bugs. some of that script is... complicated19:25
jeblairdmsimard: let's not submit any auto-generated content to project repos19:25
mordreddmsimard: I'd prefer we didn't, as we won't have any way of knowing which things we've submitted to project repos19:25
mordredgah. jeblair said that with less words19:25
jeblairdmsimard: let's put that in project-config and/or openstack-zuul-jobs19:26
dmsimardjeblair, mordred: I'm not planning on merging anything, it will be -W19:26
*** m-greene_ has joined #openstack-meeting19:26
*** felipemonteiro__ has quit IRC19:26
*** jrist has joined #openstack-meeting19:26
dmsimardif we want test drives to be in project-config and openstack-zuul-jobs, that requires merging and reverting things19:26
jeblairdmsimard: i'm fine with that.19:27
dmsimardok, sure.19:27
jeblairi'd rather do that than have people get the mistaken idea that we might want to merge the auto-generated stuff in their repos19:27
Shrewsmordred: perhaps we should outline what to expect for migration script output? like expanded templates, job name changes, etc. might help others review19:27
jeblairthis is a PR issue, not a technical one.  :)19:27
mordredShrews: ++19:27
clarkbShrews: I think that would be helpful19:27
*** StefanPaetowJisc has quit IRC19:28
dmsimardmordred: did that zuul-sphinx zuul.d fix land so we could at least put the tests in a separate file ?19:28
mordredalso - it's worth pointing out that several of the migration script 'fixes' I've made over the weekend were actually fixes or changes to old jobs or just making a new v3 version19:28
jeblairmordred: do you think we need to add anything to the infra-manual migration doc?19:28
AJaegerdmsimard: https://review.openstack.org/#/c/504797/ did not merge yet19:28
mordredoh - right ... jeblair ^^19:28
dmsimardAJaeger: thanks, just added zuulv3 topic19:29
mordredjeblair: zuul-sphinx no support zuul.d19:29
mordredso I think a doc (and/or update to infra-manual) about expected outcome from migration script - as well as a few notes about where these things expect to go ...19:30
mordredlike, migrated project-pipeline stuff goes into project-config zuul.yaml but jobs and project-templates go into openstack-zuul-jobs19:30
mordredand playbooks19:30
jeblairthat sounds helpful19:31
*** tinwood has quit IRC19:31
jeblair("i heard you migrated stuff, where the cloud is it?")19:31

clarkb#topic Gerrit 2.13 Upgrade19:37
*** openstack changes topic to "Gerrit 2.13 Upgrade (Meeting topic: infra)"19:37
clarkbThis mostly happened yesterday19:37
clarkbamazingly we fit it into the allocated outage time even though database migrations took 5 hours19:37
clarkbThank you everyone for helping make that happen19:37
fungithat was nuts19:37
clarkbUnfortunately we've turned over some new and exciting behavior around stream events and gerrit email and memory usage and so on that we are trying to address19:38
jeblairand special thanks to zaro for doing work a year ago to cause us to finish within our window :)19:38
clarkbCurrent issues are being tracked at https://etherpad.openstack.org/p/gerrit-2.13-issues19:38
clarkb#link https://etherpad.openstack.org/p/gerrit-2.13-issues19:38
clarkbFor the most part I think we have a handle on the problems and a good chunk of fixes or attempts at fixes19:38
fungiabsolutely. i don't know for sure that the reindex ordering optimization sped it up, but i'm happy to believe that was it19:39
*** rbowen has joined #openstack-meeting19:39
clarkbMy biggest concerns right now are the memory use and email slowness. I think the memory use is actually likely to be ok based on utilization today. Jeblairs change to bump max memory seemed to get us to a happy place and gerrit isn't leaking memory all over the floor (it decreases even)19:39
*** felipemonteiro__ has joined #openstack-meeting19:40
fungithough the weirdness around edits via api/webui are troubling19:40
clarkbThat all said does anyone think we need to be considering a rollback? For me I think that was on the table before the memory stuff got sorted but am feeling much more comfortable with moving forward and fixing things19:40
*** simon-AS5591 has joined #openstack-meeting19:40
fungii'm still good with rolling forward at this point19:41
jeblairyeah, the problems yesterday may have been caused by some anomolous event (there was a 500mbps outbound spike when it got bad).  or we may have needed more jvm ram.  it's not clear.19:41
jeblairyeah, if we've managed to get this far without a memory catastrophe, i think forward is the way to go19:41
ianwagree ... it's not out of bounds from what we saw with previous release that went mad occasionally too19:42
clarkbok good, I didn't want to put a bunch of effort into fixing problems if we were feeling like a revert is warranted. Glad to know no one is ready to go down that route yet :)19:42
clarkbAfter the meeting we will be applying fixes for a bunch of the problems on that list, hopefully we see improvements.19:43
clarkbOnce again thank you everyone for helping19:43
*** felipemonteiro has quit IRC19:43
clarkbProbably the other big item related to this is that we are not merging new project creation changes19:44
clarkbwant to get everything working and happy before doing that as we have had some puppet related issues around project creation and nodepool image builds19:44
clarkbanything else I've missed here? I guess see everyone after the meeting to do the great service restart of Tuesday September 1919:45
clarkb#topic PTG recap19:46
*** openstack changes topic to "PTG recap (Meeting topic: infra)"19:46
clarkb#topic Infracloud19:46
*** openstack changes topic to "Infracloud (Meeting topic: infra)"19:46
clarkbWe talked about things that weren't zuulv3 at the PTG too. I think one of the more important items was the future of infracloud19:47
clarkbI've summarized the plans around that at http://lists.openstack.org/pipermail/openstack-infra/2017-September/005585.html if you have an interest in infracloud and haven't read that email please do. Feedback is very welcome19:47
*** rbak has quit IRC19:48
clarkbTL;DR is that it probably isn't viable to move existing hardware due to cost and logistcal problems (we need rails..). As a result we likely don't want to put effort into upgrading the current cloud regions and instead let them die on the vine19:48
clarkb#topic PTG recap19:48
*** openstack changes topic to "PTG recap (Meeting topic: infra)"19:48
clarkbOther items that came up were the future of puppet testing. I think we've got a plan where we can replace beaker jobs with something a bit more test suite agnostic and even config management tool independent. This fits into zuulv3 and potentially allows for individuals to write ansible replacements of puppet things and have them be tested in similar manners19:49
clarkbWe also talked about replacing puppetboard with ara. I think dmsimard said there will be a spec up for that19:50
jeblairooh that would be nice19:50
jeblairthat would be nice too19:50
jeblair(my oohs and aahs are lagging)19:50
clarkbThe other big item on my list was talkin about monitoring of control plane srevices19:50
clarkbThere was general agreement this would be ok as long as any alerting was purely opt in by roots and if someone or group would be responsible for tuning things19:50
*** radez has joined #openstack-meeting19:51
clarkbI expect that that will be an interesting spec with probably lots of alternatives weighing the pros and cons of a variety of monitoring tools out there19:51
clarkbdmsimard: ^ you still up to writing those?19:51
ianwclarkb: will you be issuing pagers :)19:52
clarkb(I know everyone is currently busy with zuul and gerrit things so no rush, but expect tosee that in infra-specs at some point if interested or maybe you can even help write the specs)19:52
clarkbianw: please no :) and in fact that was basically that jeblair said. No pager duty19:52
clarkbwe can collect the info and use it but we aren't oncall and shouldn't have our sleep interrupted19:52
clarkbOk I think I managed to get through the entire agenda I had. Sorry if it felt rushed.19:53
clarkb#topic Open Discussion19:53
*** openstack changes topic to "Open Discussion (Meeting topic: infra)"19:53
clarkbanything else for the last ~5 minutes or so of the alotted time?19:53
jlkmonitoring and metrics can help inform future development and such, but shouldn't be waking volunteers up :D19:53
fungigood work on the agenda!19:53
* AJaeger put one item on the agenda:19:54
*** qwebirc62919 has joined #openstack-meeting19:54
AJaegerThere's a discussion about <= mitaka EOL branches at http://lists.openstack.org/pipermail/openstack-dev/2017-August/121432.html19:54
*** galstrom is now known as galstrom_zzz19:54
clarkboh the mitaka eol. Sorry that didn't make it to my local text file19:54
*** qwebirc62919 has quit IRC19:54
AJaegerand mordred has a change up at https://review.openstack.org/#/c/50496419:54
AJaegerDo we want to remove all the regexes etc like in 504964 - or first retire all <= mitaka branches?19:54
fungithere was also something on the agenda about dropping cached git clones (or not) but i think that was from the meeting prior to the ptg?19:55
AJaegeror are those not related?19:55
clarkbfungi: ya I think that is leftovers from last meeting when infra cohosted zuul19:55
clarkbAJaeger: I think we can likely do them independently especially if plan is to remove those branches anyways19:55
clarkbAJaeger: but we can sync up with tonyb later today to make sure that works for him19:55
*** StefanPaetowJisc has quit IRC19:56
AJaegerclarkb: yeah, syncing with tonyb sounds best next step...19:56
ianwAJaeger / tonyb: i can also help with branch removal in our tz if needs be ... i figured it out :)19:57
clarkbAJaeger: I know your timezones don't overlap much. I can try pinging him once not swamped with gerrit related items19:57
clarkboh ++ to ianw19:57
fungion a related note, we're slowly getting feedback on projects okay with us deleting their date-based releases from pypi19:57
*** raildo has quit IRC19:57
fungii did a batch of them right before the ptg where the release team was able to make the call19:57
AJaegerianw: will you take care of it and discuss with tonyb ? Would be best IMHO19:57
fungibut now the ones which aren't under release management are slowly trickling in19:58
mordredAJaeger, ianw: we could also just remove those right before the migration19:58
*** StefanPaetowJisc has joined #openstack-meeting19:58
AJaegerclarkb: want to give ianw an #action?19:58
mordredthe main thing is tht they cause a bunch of projects to not actually use the project-template in v319:58
clarkbas long as ianw is ok with it19:58
AJaegermordred: I don't care about timing, just that it gets done if needed19:58
ianwyes, ok19:58
clarkb#action ianw Work with tonyb to coordinate old stable branch removal from projects19:58
mordredand in v3 we can, should we want, add a branch exclusion to the project-tempalte itself19:58
mordredAJaeger: cool19:58
clarkband we are out of time19:59

b1airoYep, sounds good. I'm just feeding the animals here so will keep one eye on this.21:03
oneswigFlanders mentioned the scientific hackathon is looking for mentors21:04

oneswigWhat else would you do in a dump like Sydney while the jetlag wears off :-)21:04
oneswigNot that we are a mercenary bunch, I did see mention of summit tickets in return...21:05
oneswigHi rbudden21:05

oneswigIs next Tuesday!21:06
oneswigWe have a WG session for those attending.21:06
oneswigProbably not a big win in this time zone...21:07
b1airoGreat to hear oneswig21:07
oneswigI wanted to mention though, we are looking for lightning talks for the BoF, and in customary fashion there is now a small prize for best talk21:07
b1airoHopefully drum up some new members21:08
oneswigI think so too.  Many of the presentations of the main schedule are scientifically oriented.21:08
oneswigAm hoping to meet some new faces.21:08
*** e0ne has joined #openstack-meeting21:08
oneswig(and some old ones, of course)!21:09
priteauoneswig: Do you know if talks will be recorded?21:09
oneswigThey were last year.  They usually are.21:09
oneswigOK, that's all to add there I think.21:10

oneswigHi rajulk, thanks for coming along21:11
rajulkoneswig: thanks for inviting me21:12
oneswigThank martial, but he's missing the fun :-)21:12
*** esberglu has joined #openstack-meeting21:12
oneswigCan you describe the context for your work?21:12
oneswigIs this something used in MOC?21:13
*** powerd has joined #openstack-meeting21:13
rajulkwell we are still working on it and is not ready for use yet21:13
rajulkbut hopefully will soon be in shape21:13
*** thorst has quit IRC21:14
rajulkSo the idea is it use the idle/underutilized resources in OpenStack cloud to be offered as an HTC service21:14
rajulkThis will be a Slurm cluster comprising of virtual machines on OpenStack21:15
oneswigIs it a separate partition in slurm, or a separate instance of slurm altogether?21:15
*** Alex_Staf has quit IRC21:16
rajulkthese VMs will be added/removed from the cluster based on the resource availability driven by the resource utilization of the OpenStack cluster21:16
*** StefanPaetowJisc has joined #openstack-meeting21:16
*** thorst has joined #openstack-meeting21:16
rajulkIt's a seperate instance of slurm -  one that provides HTC service on OS21:16
b1airoHow is the OpenStack resource utilisation monitored?21:17
rajulkwe will be using watcher that will pull metrics from monasca21:17
rajulkand watcher will drive the VM provisioning21:18
oneswigrajulk: you don't have that piece in place yet, or is it currently getting developed?21:18
*** awaugama has quit IRC21:18
rajulkwe have developed an inital watcher strategy that does the job21:19
rajulkbut is yet to be tested21:19
*** thorst has quit IRC21:20
priteauAre the Slurm instances pre-emptible?21:20
rajulkso the way it works is21:21
b1airorajulk: so do you rely on Nova scheduling or force21:21
*** StefanPaetowJisc has quit IRC21:21
rajulkwhenever the utilization goes beyond a certain threshold, the job and node is supended on slurm and then then VM on OS21:21
rajulkwe use nova scheduling21:22
oneswigWhat do you do about re-creating the hpc cluster environment in OpenStack?  What about filesystems etc?21:22
*** abalutoiu__ has joined #openstack-meeting21:23
rajulkwe have used Salt as the config management tool that drives the provisioning and configuration of a new node for Slurm21:23
rajulkthe controller remains static21:23
*** ad_rien_ has joined #openstack-meeting21:24
rajulkWe'll be using an NFS file system mounted on top of swift storage21:25
oneswigsounds interesting.21:26
oneswigIt's an internal filesystem to OpenStack then?21:26
*** abalutoiu_ has quit IRC21:26
rajulkyes. initally that's the plan21:27
rajulkhowever wwe may extend it as required down the line21:27
b1airoHave you looked at any Keystone integration or would this service be seperate from OpenStack from the user's perspective?21:27
*** lakerzhou has quit IRC21:27
rajulkSo at MOC we have developed an UI that deals with these scientific tools21:28
rajulkthat is integrated with keystone21:28
rajulkand whenver a user comes on to use slurm he has to use it via that UI21:28
rajulkas of now, there will be no direct interaction between slurm and a user21:29
b1airoAh ok, so you have a science gateway of some kind21:30
*** martial has joined #openstack-meeting21:30
*** tinwood has quit IRC21:30
oneswigIf you ever get to the point of allowing users to login, I've previously used this to have them authenticated against keystone in PAM: https://github.com/stackhpc/pam-keystone21:31
rajulkit's still in development phase though21:31
martial(back, sorry)21:31
*** armstrong has joined #openstack-meeting21:31
*** noslzzp has quit IRC21:31
b1airoOk, so presumably the OpenStack SLURM is just one computational resource behind that gateway, which would also include traditional HPC systems?21:31
oneswigwelcome back martial :-)21:31
martial(will check the logs for the presentation)21:31
*** tinwood has joined #openstack-meeting21:31
b1airorajulk: what gateway software do you use there?21:32
rajulkAs of now yes, slurm is running behind the gateway for the user21:32
priteaurajulk: when you say utilization goes beyond a threshold, is that looking at per-node utilization (CPU, mem, etc.) or number of instances across the whole cluster?21:33
rajulkthere is a different team working on that but as I know it's built on top of troposphere and atmosphere from cyverse21:33
*** gouthamr has joined #openstack-meeting21:35
rajulkpriteau: it's the utilization across the cluster on CPU and memory for a certain period of time21:35
*** noslzzp has joined #openstack-meeting21:35
priteauAnd how do you decide which VM to kill?21:35
b1airoInteresting possibilities to look for idle VMs in SLURM there...21:36
rajulkpriteau: well there's not logic behind that yet. just pick the first one in the list and we dont kill a VM but just suspend it21:36
oneswigrajulk: your presentation mentions multi-node jobs are future work, what's stopping that?21:37

*** ykatabam has joined #openstack-meeting21:38
rajulkoneswig: theortically nothing.we haven't tried that yet. the only concern that was there initially that should we stop all the nodes in the cluster or just a portion of it21:39
rajulkand if a portion that how to figure that and work around it21:39
rajulkso began with a simpler case of single node jobs21:40

*** ricolin has quit IRC21:46
oneswigIt's coming together - apologies to anyone who has commented and I've not responded for a couple of days.  Quite a bit going on at once.21:46
oneswigmartial: not sure that was me... I've been largely elsewhere today.21:47
rbuddenmight have been me21:48
oneswigI'm working on an SKA infrastructure study to replace the Cray one, should have that in review tomorrow21:48
rbuddeni was making lots of edits before this meeting ;)21:48
rbuddeni sent oneswig an email for review, but any feedback is welcome21:48
oneswigrbudden: looking for the prize for the most up-to-date entry, huh? :-)21:48
martialoneswig: interesting, that person had your face icon ... you are being identity theft-ed on book reviews of your own chapter ... sneaky21:48
hogepodgeSept 29 is the hard deadline21:48
hogepodgeAbsolutely no edits after that. If it's not ready we won't have time to produce the book.21:49
oneswigThanks hogepodge21:49
rbuddenoh nice, i have a few more days ;)21:49
oneswigWe can propose cover images for this edition.21:49
hogepodge(Kathy has entrusted me to remind everyone of that as often as possible... I don't want to let Kathy down) :-D21:49

hogepodgeDenise got stickers approved, so I just need to know who to mail them to for the conference.21:54
rbuddeni can volunteer for that21:54
oneswigIU or PSC booths might be good places to deliver to - rbudden?21:54
oneswigah, great21:54
rbuddenyes, i’ll be at SC Sun-Fri21:54
oneswigb1airo: what's the latest on the BoF?21:54

martialb1airo: our usual BoF / Lightning Talks22:00
oneswigWe upgraded to Pike today, it worked!22:00
b1airomartial: those are already in, I mean the main Forum22:00
oneswigb1airo: might be a good thread for openstack-sigs[scientific]?22:00
martial(I am still confused about this Forum thing then)22:01
martialoneswig: might be especially since we are out of time22:01
priteauoneswig: Anything to look out for before moving to Pike? I keep cherry-picking bug fixes from it into our Ocata deployment22:01
oneswigpriteau: Mark and johnthetubaguy in our team did a fair bit of prep.  We use Kolla.  There were issues with docker_py -> docker.  Also, we had problems with RabbitMQ hosts mangling /etc/hosts with repeated entries.  Finally, a racy problem with updating haproxy which was fixed by a cherry-pick from master22:03
oneswigAnd I forgot to merge a PR I'd left dangling, doh.22:03
oneswigKolla worked really well for us though.22:03
oneswigAh, we are way over time.22:03
rbuddenoneswig: I would be very interested in thoughts/war storries of Kolla22:03
rbuddenfor another time then!22:04
