| lyarwood | not a Nova bug | 16:04 |
| lyarwood | but https://bugs.launchpad.net/tempest/+bug/1905725 is blocking the ceph job at the moment on master | 16:05 |
| openstack | Launchpad bug 1905725 in tempest "test_attach_scsi_disk_with_config_drive fails during cleanup when using RBD for Glance and Nova" [Undecided,New] - Assigned to Lee Yarwood (lyarwood) | 16:05 |
| lyarwood | https://review.opendev.org/c/openstack/tempest/+/764337 posted and I've asked for reviews in #openstack-qa | 16:05 |
| gibi | I hope gmann can look at it | 16:05 |

| lyarwood | I'll add an er for that last issue after the meeting | 16:08 |
| gibi | lyarwood: thanks | 16:08 |
| gibi | this is pretty low, and got even lower this week, meaning we have a lot of failures that has no e-r signature | 16:09 |
| gibi | Please look at the gate failures, file a bug, and add an elastic-recheck signature in the opendev/elastic-recheck repo (example: #link https://review.opendev.org/#/c/759967) | 16:09 |
| gibi | any gate bug we need to talk about? | 16:09 |
| gibi | personally I got hit by https://bugs.launchpad.net/nova/+bug/1823251 this week so I spend days running func tests locally in random order but I still cannot reproduce it locally | 16:10 |
| openstack | Launchpad bug 1823251 in OpenStack Compute (nova) "Spike in TestNovaMigrationsMySQL.test_walk_versions/test_innodb_tables failures since April 1 2019 on limestone-regionone" [High,Confirmed] | 16:10 |
| *** slaweq has quit IRC | 16:10 | |
| gibi | what I see is that the test cases in question takes a long time to run on the gate but also the runtime is varying a lot | 16:11 |
| stephenfin | I've seen a couple of the unit test failures due to eventlet, but I don't think there's much to be done about that that isn't serious work | 16:11 |
| gibi | like 50sec - 800sec | 16:11 |
| lyarwood | gibi: yeah I've also hit that one | 16:11 |
| lyarwood | and the negative evacuation bug elod has listed in the stable section of the meeting | 16:11 |
| gibi | lyarwood: for the evac one there is a comment in the bug with a suggestion | 16:12 |
| *** slaweq has joined #openstack-meeting-3 | 16:13 | |
| gibi | or at least with an observation | 16:13 |
| lyarwood | gibi: ack yeah I'm looking at it now, it's weird how this is being seen more on the older bionic nodes | 16:13 |
| lyarwood | gibi: I'll push an ER and update the change shortly | 16:14 |
| gibi | cool | 16:14 |
| gibi | thanks | 16:14 |

| gibi | #topic Open discussion | 16:19 |
| *** openstack changes topic to "Open discussion (Meeting topic: nova)" | 16:19 | |
| gibi | we have two items | 16:19 |
| gibi | (lpetrut): Hyper-V RBD support | 16:19 |
| gibi | The upcoming Ceph release will include RBD Windows support, so we'd like to add Hyper-V driver support | 16:19 |
| gibi | specless bp: https://blueprints.launchpad.net/nova/+spec/hyperv-rbd | 16:19 |
| gibi | lpetrut: as far as I understand it only impact the hyperv driver | 16:20 |
| lpetrut | yep | 16:20 |
| lpetrut | the nova changes are minimal | 16:20 |
| lpetrut | basically just letting the driver know that RBD is supported while os-brick handles the plumbing | 16:20 |
| sean-k-mooney | my main concern was testing | 16:20 |
| sean-k-mooney | i think it makes sense to proceed as a specless blueprint | 16:21 |
| sean-k-mooney | but it would be nice to see it tested in third party ci | 16:21 |
| sean-k-mooney | you expalined you plan to test it in os-brick | 16:21 |
| sean-k-mooney | so my main question is does the nova team feel that is enough | 16:21 |
| sean-k-mooney | or do we want the same job to run on changes to the hyperv driver | 16:21 |
| lpetrut | we already have a Hyper-V CI testing all the OpenStack projects that support Windows (e.g. nova, neutron, cinder, os-brick) | 16:22 |
| sean-k-mooney | lpetrut: yep but you are only doing lvm testing | 16:22 |
| lyarwood | sean-k-mooney: nope, they use os-brick on Windows now | 16:22 |
| lyarwood | sean-k-mooney: so I assume this is using their full blown third party setup | 16:22 |
| lpetrut | what Sean's saying is that the Nova job only covers iSCSI while we have os-brick test jobs for other backends | 16:23 |
| sean-k-mooney | yep | 16:23 |
| sean-k-mooney | there are 3 os-brick jobs for hyperv | 16:23 |
| sean-k-mooney | only the isusi one triggers on nova | 16:23 |
| sean-k-mooney | if we are fine with that then cool | 16:23 |
| lpetrut | we're trying to limit the number of jobs because of the available infrastructure. any nova change that breaks other storage backends will be caught by os-brick | 16:24 |
| sean-k-mooney | only after the change merges | 16:24 |
| lpetrut | that's ok, 3rd party CIs aren't voting anyway | 16:24 |
| sean-k-mooney | right but we do look at them | 16:24 |
| sean-k-mooney | as i siad im +1 on this porposal | 16:25 |
| sean-k-mooney | just wanted to bring up that point | 16:25 |
| lyarwood | ah right sorry misunderstood the issue, I'd assume we would want a simple third party job still to catch any virt driver breakage early | 16:25 |
| lyarwood | within Nova | 16:25 |
| lpetrut | sean-k-mooney: definitely, thanks for raising those concerns | 16:25 |
| sean-k-mooney | lyarwood:that was basically what i was asking | 16:26 |
| lyarwood | right, I'd vote to have it assuming rbd will be as popular with hyperv as it is with libvirt | 16:26 |
| lyarwood | but it shouldn't block it either way | 16:26 |
| lyarwood | as long as it's covered somewhere | 16:26 |
| sean-k-mooney | yep if capstity is a concern then i think its fine to rely on os-brick but even a nightly or weekly nova run of all 3 jobs might be nice | 16:27 |
| gibi | I'm OK to go forward with the bp. lpetrut if it is possible try to provide CI coverage in nova for the RBD track too | 16:27 |
| gibi | a periodic run like sean-k-mooney suggest could be a minimal extra load on your infra | 16:28 |
| lpetrut | gibi: you mean testing RBD for one in every X patches ? | 16:28 |
| lpetrut | that would work | 16:28 |
| sean-k-mooney | lpetrut: yep so trigger a run once a week or once a night | 16:28 |
| gibi | lpetrut: running the RBD job once a day | 16:29 |
| gibi | or so | 16:29 |
| *** e0ne has quit IRC | 16:29 | |
| lpetrut | ok, we can do that | 16:29 |
| sean-k-mooney | lpetrut: its mainly to narrow down the set of possible problem patches | 16:29 |
| gibi | then I don't see any objects. So I will approve the bp without spec after the meeting | 16:30 |
| gibi | lpetrut: thanks for pushing tihs | 16:30 |
| lpetrut | thanks! | 16:30 |
| sean-k-mooney | https://review.opendev.org/c/openstack/nova/+/763550 is the change for those that are intersted in reviewing | 16:30 |
| gibi | sean-k-mooney: you have a topic too | 16:31 |
| lpetrut | one difference compared to libvirt is that we're mounting the disk, hyper-v can't use librbd as qemu does. we're exposing a virtual SCSI disk | 16:31 |
| sean-k-mooney | yes basiclly for the libvirt driver we currentl use the metadat element in the xml to store some useful info for debugging | 16:31 |
| lpetrut | gibi: I've just set the topic to "hyperv-rbd" | 16:32 |
| gibi | lpetrut: ack thanks, the implementation details can be discussed in the review | 16:32 |
| gibi | sean-k-mooney: yes | 16:32 |
| lpetrut | definitely, just thought that it might be worth mentioning | 16:32 |
| sean-k-mooney | was waiting for previous topic to finish | 16:33 |
| gibi | lpetrut: thanks | 16:33 |
| gibi | sean-k-mooney: I think we can move to your topic | 16:33 |
| sean-k-mooney | lpetrut: we do somethign simiar in livbirt in that the gust sees a virtio device or scie device depneing on the bus selected anyway i dont think that is a problem | 16:33 |
| sean-k-mooney | cool | 16:33 |
| sean-k-mooney | am so ya today we store info like the flavor name and how many cpus we have in the medata in the libvit xml | 16:34 |
| sean-k-mooney | but we dont store the flavor extra spec or image properties | 16:34 |
| sean-k-mooney | when we review reports form cosutoem we often have the logs | 16:35 |
| sean-k-mooney | with the xmls but no access to the api to get the flavors | 16:35 |
| sean-k-mooney | so i want to start storign the falvor extra specs and image prperties in the xml | 16:35 |
| sean-k-mooney | and normalise soem ot the other element | 16:35 |
| sean-k-mooney | for example we have the flavor name but not uuid but image uuid but not name | 16:35 |
| sean-k-mooney | so i want to put both | 16:35 |
| gibi | make sense to me | 16:36 |
| sean-k-mooney | i would like to do this as a specless blueprint and discuss in the code patch but i can do a small spec if required | 16:36 |
| lyarwood | I'm okay with that if it doesn't bloat the XML | 16:36 |
| lyarwood | otherwise we can just log it at an INFO level within the driver | 16:36 |
| lyarwood | during the build | 16:36 |
| sean-k-mooney | it should not extend it much | 16:36 |
| lyarwood | but I guess that doesn't persist as well | 16:36 |
| lyarwood | as logs rotate etc | 16:37 |
| sean-k-mooney | we dont typically have more then ~10 extra specs | 16:37 |
| lyarwood | kk | 16:37 |
| sean-k-mooney | and the xml is only logged at debug level | 16:37 |
| lyarwood | right but if we ever need it again we can just dump it from the domain | 16:37 |
| gibi | sean-k-mooney: I'm OK to have this as a specless bp as this only change a freeform part of the domain xml | 16:37 |
| sean-k-mooney | yep its technically not part of any public api we provide its just debug metadata | 16:38 |
| sean-k-mooney | ok ill file the blueprint after the meeting and submit a patch | 16:38 |
| sean-k-mooney | we can discuss futher in gerrit and if there are concerns we can create a spec if need | 16:39 |
| gibi | also as we discussed earlier when the flavor and image data changes then also the domain is regenerated | 16:39 |
| gibi | so it is easy to keep it up tod ate | 16:39 |
| gibi | to date | 16:39 |
| sean-k-mooney | yep in rebuild and resize we already regerneate teh xml and metadata | 16:39 |
| gibi | Ok | 16:40 |
| gibi | anyhing else for today? | 16:40 |
| sean-k-mooney | that looks like a no | 16:41 |
| sean-k-mooney | nothing else from me in anycase | 16:41 |
| gibi | then thanks for joining today | 16:41 |
| sean-k-mooney | o/ | 16:41 |
| gibi | have a nice rest of the day! | 16:41 |
