gibithe https://bugs.launchpad.net/nova/+bug/1882521 has been marked Critical16:02
openstackLaunchpad bug 1882521 in OpenStack Compute (nova) "Failing device detachments on Focal" [Critical,Confirmed] - Assigned to Lee Yarwood (lyarwood)16:02
gibilyarwood opened a qemu bug https://bugs.launchpad.net/qemu/+bug/189480416:02
openstackLaunchpad bug 1894804 in QEMU "Second DEVICE_DELETED event missing during virtio-blk disk device detach" [Undecided,New]16:02
bauzaswell, technically, we haven't regressed and our gate isn't broken16:04
*** lyarwood has joined #openstack-meeting-316:04
lyarwood\o16:04
bauzasso the Critical status is remarkable16:04
gibido we consider this as release critical? shall I mark it with  victoria-rc-potential tag?16:04
lyarwoodwhich bug is this sorry?16:04
gibihttps://bugs.launchpad.net/nova/+bug/188252116:04
openstackLaunchpad bug 1882521 in OpenStack Compute (nova) "Failing device detachments on Focal" [Critical,Confirmed] - Assigned to Lee Yarwood (lyarwood)16:04
lyarwoodso how is this is not critical?16:05
bauzasmy point was, I totally understand this being a priority16:05
lyarwoodfocal is the supported os from V16:05
lyarwoodfor*16:05
bauzasis this used in the gate ?16:05
lyarwoodyes16:05
bauzasok, then tagging the bug16:05
bauzasif so, nothing to complain16:06
bauzasdo we have a logstash query ?16:06
lyarwoodI can write one up if it's required16:06
bauzastrying to see how much this impacts16:06
gibilyarwood: it is actually not breaking the gate right now, is it?16:06
lyarwoodat the moment we've added the failing tests to a blacklist on a number of jobs16:07
bauzasgibi: to answer your question, looks like it's a good candidate indeed16:07
bauzasgibi: that's my whole question16:07
gibilyarwood: and we have the intention to remove them from the backlist before V?16:07
*** sean-k-mooney has joined #openstack-meeting-316:07
bauzasCriticals are for either regression or gate failures16:07
gibiif so then it is release critical16:07
bauzasagreed on this one16:07
lyarwoodgibi: right that's my understanding16:07
gibiOK16:07
gibithen I added victoria-rc-potential to the bug too16:08
bauzasagain, I think we need to identify the impact16:08
bauzasI haven't seen personnally the gate borked by this one but I could be wrong16:08
sean-k-mooneyby which?16:08
gibibauzas: it is not borked as the test is turned off16:08
sean-k-mooneymissed the start16:08
lyarwoodbecause it hasn't moved to focal yet16:08
sean-k-mooneyoh focal16:09
lyarwoodsean-k-mooney: the focal detach bug16:09
lyarwoodsean-k-mooney: https://bugs.launchpad.net/nova/+bug/188252116:09
openstackLaunchpad bug 1882521 in OpenStack Compute (nova) "Failing device detachments on Focal" [Critical,Confirmed] - Assigned to Lee Yarwood (lyarwood)16:09
sean-k-mooneyya so we think that likel a cirros/qemu bug not nova right16:09
bauzasok, now I have a better understanding, thanks16:09
sean-k-mooneyi know we may be able to adress it in nova better16:09
sean-k-mooneybut the difference in behavior on focal is likely cause by somethign external to nova16:09
sean-k-mooneyi dont think we should be holding swapting the gate jobs to focal because of this16:10
lyarwoodwell the knock on impact is that we lose some coverage in the gate16:10
bauzassean-k-mooney: is that 100% reproducible when you detach a device on Focal ?16:10
sean-k-mooneyif we really need too we could run a centos-8 job for the test coverage16:10
lyarwoodbut you're right there's not a lot we can do about it in Nova16:10
sean-k-mooneybauzas: not 100%16:11
lyarwoodsean-k-mooney: what about Fedora? /s16:11
sean-k-mooneybauzas: you need suffenct load16:11
sean-k-mooneylyarwood: no16:11
sean-k-mooneyi dont think we shoudl have gating jobs on fedora16:11
gibiso we move to focal, keep the test disabled, and if qemu or us figure out a fix then we build an RC+1 out of it16:11
lyarwoodnote the /s16:11
lyarwoodgibi: ack16:11
sean-k-mooneycentos-8 has the same verion of qemu and libvirt as focal16:11
bauzassean-k-mooney: lyarwood: so the logstash query is like super important16:11
gibi#action lyarwood to provide a logstash query16:12
bauzasgibi: is there something we need to do from a nova perspective ?16:12
gibican we move on?16:12
gibibauzas: handle the communication in the qemu bugreport?!16:12
bauzasbecause from my understanding, I don't see anything actionable from nova during RC116:12
sean-k-mooneybauzas: we may be able to handel the detach more gracefully16:12
lyarwoodsean-k-mooney: that still wouldn't fix it btw16:12
bauzasor requiring a patch to be shipped in RC1, if you prefer16:12
bauzasmy whole point16:13
bauzasI don't see a need for us to leave a Critical bug unresolvable on our side16:13
gibibauzas: if qemu devs could point out a workaround that is implementable on nova side then we can release that16:13
lyarwoodthere's nothing in Nova at the moment but I think we still need to track this to remove tests from the blacklist before GA if QEMU is fixed16:13
sean-k-mooneyok so maybe just drop critical and make it high16:14
lyarwoodsure if it's going to stop us going around in circles ;D16:14
sean-k-mooney:)16:14
gibilets back to this next week16:14
gibimoving on16:14
bauzasthe point is, we're going to track this bugreport as something due for RC116:14
bauzasbut if that doesn't bother people here...16:14
bauzas:)16:15
gibiI think we would like to track it16:15
gibianyhow16:15
gibibeside this single bug there are  36 new untriaged bugs (+7 since the last meeting): https://bugs.launchpad.net/nova/+bugs?search=Search&field.status=New16:15
gibiso there are inflow we have to look at16:15
gibiand triage16:15
gibiif you see regressions then please tag them with victoria-rc-potential16:16
gmannyeah that is one the blocker for Focal migration - http://lists.openstack.org/pipermail/openstack-discuss/2020-September/017104.html16:16
bauzasgibi: I'm on bug triaging next week16:16
