tpatilHere, if HA_Enabled metadata key is not set to the instance, then by default considered as False and if evacuate_all_instances is set to True,  all instances from the failed compute host will be evacuated04:09

*** slaweq has quit IRC04:16
tpatilYes, if HA_Enabled is True, it will evacuate that instance04:16
tpatilAnother work item: Evacuate non-recovery (’HA_enabled = False’) instances in shutoff status at host failure except specified tenants04:16
tpatil#link : https://blueprints.launchpad.net/masakari/+spec/evacuate-non-recovery-instances-in-shutoff-status-at-host-failure-except-specified-tenants04:16
tpatilI have understood about introducing another new config option to tell masakari engine to evacuate the instance to shutoff state if HA_Enabled metadata set to the instance is False.04:17
tpatilSecond part of this blueprint is not clear about adding new config option to specify tenants04:18
*** ykatabam has joined #openstack-meeting04:18
tpatil#action: tpatil to check with samP about this particular requirement04:19

*** tesseract has quit IRC16:32
slaweqonce some timeout when processing neutron request16:32
slaweqso there are various random issues there16:32
slaweqI think that we should first move this job from legacy to zuulv316:32
slaweqand than maybe run only neutron related tests on it16:32
njohnstonmakes sense16:32
slaweqthan it should be hopefully better16:32

njohnstonno, never seena. timeout there16:38
slaweqlogstash also shows only this one occurence of such issue16:39

slaweq#topic Tempest/Scenario16:41
*** openstack changes topic to "Tempest/Scenario (Meeting topic: neutron_ci)"16:41
slaweqI found few issues from last week16:41
slaweqfirst of all, funny issue with tempest-slow-py316:41
slaweqit seems that on compute node it still runs on python 2.716:41
slaweqI found it where I checked logs: https://ba2b4fc750309c3f0760-e6e77a9441ae9cccde1b8ed58f97fc24.ssl.cf2.rackcdn.com/690098/6/check/tempest-slow-py3/4a5cd35/compute1/logs/screen-q-agt.txt.gz16:42
slaweqon controller node py36 is used already16:42
slaweqI will propose patch to fix that this week16:42
slaweq#action slaweq to fix python version in tempest-slow-py3 job16:44
slaweqfrom other issues, I checked why this dvr mutltinode jobs is failing 100% of times16:44
slaweqit seems that it is failing every time on neutron_tempest_plugin.scenario.test_migration.NetworkMigrationFromHA tests16:44
slaweq    I think this is related (again) to some wrong rootwrap filters:16:45
slaweq    https://12dcf03ddbc1f4ac6c48-3214406b4544fce2f9d807df6ea4fe3f.ssl.cf2.rackcdn.com/677166/13/check/neutron-tempest-plugin-dvr-multinode-scenario/31d556c/compute1/logs/screen-q-l3.txt.gz16:45

clarkbLast week was the summit. I am feeling extra zombie like after that trip. The jet lag has been harsh. I expect others are in a similar position19:02

clarkb#topic OpenDev19:05
*** openstack changes topic to "OpenDev (Meeting topic: infra)"19:05
clarkbWe need to renew the opendev.org cert19:05
clarkbI think we can manage to do that via LE now19:05
clarkbwe'll just need a handler that restarts gitea backends when the cert updates (and maybe we can serialize those?)19:05
clarkbfiguring that out is likely to be my tomorrow task19:06
*** AJaeger has joined #openstack-meeting19:06
clarkband we have plenty of time to sort it out and if we can't for whatever reason can always buy another cert for a yer19:06
* AJaeger waves late19:06
fungiyeah, it's still something like 2.5 weeks out19:07
ianwi guess each gitea host will have it's own cert?19:07
clarkbianw: yes I think so19:07
*** ociuhandu has joined #openstack-meeting19:08
fungias long as le doesn't scoff at 8 hosts requesting ssl certs for the same name19:08
clarkbthat should be well within the rate limits iirc.19:09
ianwfungi: i don't think it will matter; each will get a different txt value to put into _acme-challenge, and it should "just work"19:09
ianwfamous last words :)19:09
fungithat'll presumably be easier than refactoring things to have ssl terminated on the lb19:10
clarkbwe can also have an altname that matches each backend specifically to help distinguish them?19:10
fungitrue19:10
clarkbthat may also make LE happier if the records are different each time19:10
fungiif it works the way we've done it for other services, i think that happens by default19:11
*** ociuhandu has quit IRC19:12
clarkb#topic Update Config Management19:14
*** openstack changes topic to "Update Config Management (Meeting topic: infra)"19:14
clarkbI'm not sure this has been called out elsewhere yet but was mentioned at the PTG. Apparently mordred thinks we shouldn't wholesale move to podman yet19:14
AJaegeroh, why?19:15
clarkbwe'll be getting dev builds via the ubuntu ppa for podman and some commands don't work as before. Idea is to try it a bit first with review(-dev)19:15
AJaegerso, "compatibility" ?19:15
clarkbI think we are happy with compatibility since rhel8 docker command is podman so it must be fairly compatible. More just that we aren't sure if the dev packaging from the ppa poses any concerns yet and users will need to get back to using docker commands instead of docker-compose commands and so on19:16
clarkbThen when we are happy with the results we can do broader changes19:17
AJaegerI see...19:17
*** bbowen has joined #openstack-meeting19:17
fungilack of an interleaved log viewer was noted as an unfortunate loss for switching away from docker-compose19:17
clarkbAnything else on this topic or should we move on?19:19
* fungi has nothing19:19
ianwso for new work, like testing out the nodepool-builder images, should we use docker or podman?19:19
ianwor in that case, does it not matter so much?19:19
clarkbianw: aiui mordred thinks we should use docker for now and keep podman to review(-dev)19:19
clarkbbut I may have misunderstood and maybe he meant just don't go changing existing docker usage yet19:20
clarkbmy hunch is that its probably ok for any new use of containers19:20
ianwok19:21
clarkb#topic Storyboard19:22
*** openstack changes topic to "Storyboard (Meeting topic: infra)"19:22
clarkbfungi: ^ anything new from storyboard? I expect not given the summit19:23
fungithere was an sb onboarding session at the ptg, but nobody showed up so diablo_rojo_phon and tonyb turned it into an openstack technical election officials working session19:23
fungiother than that, nothing new i'm aware of19:23
clarkb#topic General topics19:24
*** openstack changes topic to "General topics (Meeting topic: infra)"19:24
clarkb#link https://etherpad.openstack.org/p/OpenDev-Shanghai-PTG-2019 PTG Notes19:24
clarkbI/we tried to take notes at the summit/forum/ptg19:24
clarkbThe item on my todo list before opendev.org LE certification is to write up a summary and send it to the infra list19:25
clarkbI did want to point out that the etherpad is there for people to browse too and that if you have questions about specific topics feel free to ping me nowish and I'll add it to the summary or you can followup on that thread when it exists19:25
clarkbOur meeting with the gitea maintainers went well. We were able to show them some of our build and test tooling to test out the elasticsearch indexing19:26
clarkbfrom that we discovered that the china golang and google golang proxies had different content for the CORS package :/19:27
fungithat's scary19:27
clarkbthey also acknowledged that the performance issues we've hit are a major problem and they have other users struggling with that too. I hope that means we continue to see improvements with performance19:27
fungithough we also upgraded19:28
fungiand the new version should have at least some performance improvement over what we were running before last week19:29
clarkbAlso their community is largely on discord and is activ ethere if we want to communicate with them further19:30
clarkbI've got a discord account somewhere, but I should prbably set that up for gitea now19:31
*** Shrews has joined #openstack-meeting19:31
clarkband I'll try to write all this up properly between now and tomorrow sometime19:32
clarkbfungi: seems like there were wiki changes prior to leaving for the summit. Were you able to check on those?19:32
funginope19:32
fungii mean yep some changes merged, nope i did not find time yet to follow up further19:33
clarkbFor static.openstack.org mnaser volunteered to do the job changes on the openstack side of things19:34
clarkbianw: AJaeger ^ I think that means our next step is to create afs volumes, then mnaser can upate jobs to publish to afs and static.o.o, we verify content, then flip things over site by site?19:35
AJaegerclarkb: I did the first jobs already, happy to hear that mnaser will do the rest!19:35
AJaegerclarkb: https://review.opendev.org/#/q/status:open+project:openstack/project-config+branch:master+topic:static-services19:35
clarkbthanks!19:35
ianwok, i can look at the volumes for ^19:35
AJaegergetting those jobs done helped to answer a couple of questions and finish the spec ;)19:36
clarkbI think we should be able to have both sites exist in parallel and then flip dns when we are happy with the new side of things19:36
AJaegerplease check also whether those jobs are really doing what we wanted19:36
clarkbAnd finally we get to ask.openstack.org19:38
clarkb#link http://paste.openstack.org/show/785843/ Some logs19:38
clarkbthese logs (that frickler collected?) seem to show there are segfaults19:38
ianw"or similar nasty error"19:40
ianwthat's oddly unspecific19:40
clarkbone thing we can try if it is the log rotate that causes this is to ensure we are using copy truncate19:41
clarkband not the rotate in place behavior19:41
ianwsystemd-sysv-generator[6394]: Overwriting existing symlink /run/systemd/generator.late/jetty8.service with real service.19:42
ianwwhat does that mean?19:42
ianwit must be coming from puppet, it's very frequent19:42
clarkbianw: if jetty is a sysv init script that may be a result of it setting up the compat shims19:43
ianwthere's a /etc/init.d/jetty8~ file19:45
ianwi've removed that19:45
clarkbk19:45
*** ykatabam has joined #openstack-meeting19:46
ianw /etc/init.d/jetty is a symlink to /etc/init.d/jetty819:46

oneswigThere was some concern in the corridors about changes to the t&cs here https://grafana.com/trademark-policy/ which mean products incorporating grafana now require the written permission of grafana labs.21:19
*** ociuhandu has quit IRC21:19
martialoh weird21:19
oneswigindeed, weird.  We don't make a product so the details somewhat passed me by.21:20
martialhow do you define "incorporating"? ... started as part of a docker-compose?21:20
oneswigI would have thought more generally than that. If it's installed as part of something you sell.21:21
martialwe do not sell products per say so still kind of hard to "grasp" but thanks will pass the info along21:21
martialwas Blair there with you?21:21
*** bbowen has joined #openstack-meeting21:22
oneswigNo, not this time.  Sam Morrison and Andy Botting were holding the fort for the antipodeans, did a great job.21:22
*** ociuhandu has joined #openstack-meeting21:23
oneswigThe major disappointment for the SIG was the scheduling of SIG time.  It was a table in the PTG, which meant there weren't many operators around.  But also, there were almost no locals in the PTG.  And there wasn't a cross-project time when (eg) the Ironic cores could come along and join in.21:24
oneswigAs a result, there were ~4 of us compared with ~100 on a good summit.21:24
jmloweIt's so much easier for a number of us to go to, well, anywhere but China21:26
oneswigjmlowe: yeah, that was a running theme.21:27
rbuddenheh21:27

martialstill a bummer21:28
trandlesHi folks21:29
oneswigI hope the foundation managed to stir up some interest in the open source community among the locals, but it did look like a cultural divide.21:29
oneswighi trandles, just in time :-)21:29
trandlesSorry, home sick today and lost track of the time21:29
oneswigget well soon, you've got a flight to catch21:30
trandlesLol yeah...started on Friday, yesterday was rough but I'm over the hump I think. Should be in the office tomorrow.21:30
trandlesReading back...I haven't seen any formal announcement on upcoming summits, but Vancouver would be good.21:31
trandlesDid anyone (other than Tim Bell) notice that neutron is talking about deprecating linuxbridge support? I know some of this community, including CERN, was using it everywhere.21:31
oneswigyes I saw that and am surprised by it.21:32
oneswigI think it's still the simplest and fastest of the software bridges.21:32
trandlesDefinitely the simplest. Has OVS performance ever caught up?21:32
oneswigNo.21:32
oneswigAt least, it hadn't last week when we last tried it.21:32
rbuddenThis surprises me. It’s definitely the simplest.21:33
oneswigActually, correction, that was OVS vs Tungsten Fabric21:33
trandleshrm...maybe this SIG needs to speak up then21:33
oneswigjmlowe: you still using it at large scale?21:33
rbuddenThough OVS had a decent set of tools for debugging, etc that was nice21:33
jmloweI also picked up a pre SC cold on Friday21:34
trandlesOne of the reasons they cite is feature set falling behind other solutions. Conversely, the simplicity is nice when you care about raw performance.21:34
jmloweI'm not happy about this linuxbridge deprecation21:34
oneswigtrandles: +1 for me21:34
jmloweI'm still using linuxbridge at least through 202021:35
oneswigI think the issue is nobody's stepping in to look after it with the Neutron project.21:35
oneswigThose people are I expect all paid to work on shiny stuff.21:35

jmloweoneswig : ever test the performance of ovs vs ovn?21:37
oneswigFunny you should ask.21:37
oneswigI benchmarked it for Sydney - 2 years ago - using 100G CX5 NICs21:38
oneswig1 sec21:38
*** ykatabam has joined #openstack-meeting21:39
jmlowefor bonus points ever try the ovs offload in connect-x cards?21:39
oneswigyes it's brilliant, like flossing with dynamite21:40
oneswigoccasionally, it blows up :-)21:40
martialoh well the advantage of having disposable hardware :)21:40
oneswigJust uploading the presentation somewhere.21:41
trandlesoneswig, saw the foundation announcement, congrats21:41
oneswigtrandles: thanks :-)21:42
rbudden?21:42
rbuddeni think i missed the memo21:42
oneswigHere's the slides http://www.stackhpc.com/resources/5-ways-with-hypervisor-networking.pdf21:42
oneswigrbudden: we got ourselves on the marketplace and joined the foundation, that's all :-)21:43
rbuddenoh nice :)21:43
jmloweon the upside I did see that sriov live migration is a thing in train21:43
oneswigjmlowe: I believe so, with Netronome smart NICs21:44
*** ociuhandu has joined #openstack-meeting21:44
jmlowebah, I didn't see that qualifier21:44
oneswigOn that presentation linked above, there's OVN vs OVS vs LinuxBridge vs SR-IOV vs ASAP2 - look for a slide titled "TPC/IP performance - iperf"21:44
oneswigNB We tested OVN again last week and it was better than this but still not the quickest thing out there.21:45
oneswigActually, I hear the hardware OVS offload is a good deal more mature now and in production at large scale.21:49
*** ociuhandu has quit IRC21:49
jmlowelooks like ASAP2 might be a real contender21:51
oneswigI think so, potentially.  It would be good to see how performance degrades with increasing numbers of flows but at any level it will beat a software switch by a huge margin.21:53
oneswigWe should talk SC21:53
oneswigAny good schedule picks?21:54
jmloweWell there's this workshop Monday morning21:54
martialwhich one is that?21:55
martialMonday afternoon is CANOPIE21:55
martialon Sunday I will be at "The Next Platform" event21:56
martialah bummer, Monday is also the "NVIDIA 2019 Special Address"21:56
oneswigI'll be keeping an eye out for AMD GPU performance comparisons.21:57

oneswigNearly time to close, alas21:59
rbuddenno idea, but we know the Ramen spot if you’re interested ;)21:59
oneswigI'll be at Sams #3, the diner22:00
