03:41:39 alex_xu stephenfin: with the current upgrade plan, does it means we lose the ability LM the instance?
03:42:47 alex_xu stephenfin: since the control-plane is asking PCPU, then there is no way to do that. If the opeartor is going to upgrade the OS also, then he need LM the existing instance to other host. But we there is PCPU on old nodes also.
03:43:51 alex_xu stephenfin: except we required the operator to do a upgrade of openstack first before upgrade OS. But I don't know whether it works always, is there any case the user have to upgrade the OS first before upgrade OpenStack since some dependence only available on the new version of OS
03:47:24 alex_xu sean-k-mooney: efried ^
04:22:40 HagunKim Can I delete them manually?
04:22:40 HagunKim In mariadb, there are many vm instances with vm_state=deleted. (more than 4000 over)
04:22:40 HagunKim Hello, I have a question for using openstack nova.
04:23:52 alex_xu HagunKim: you should use nova-manage db archive_deleted_rows
04:42:03 openstackgerrit ya.wang proposed openstack/nova master: vCPU model selection https://review.opendev.org/670298
04:42:04 openstackgerrit ya.wang proposed openstack/nova master: Support reporting multi CPU model traits https://review.opendev.org/670300
04:42:04 openstackgerrit ya.wang proposed openstack/nova master: Add compatibility checks for CPU mode and CPU models and extra flags https://review.opendev.org/670299
04:51:06 HagunKim eg. DELETE from shadow_instance_actions_events;
04:51:06 HagunKim Can I delete all data in shadow tables manually?
04:51:06 HagunKim alex_xu: Thanks. I have some duplicated data in shadow tables. So "nova-manage db archive_deleted_rows" occurs an error and not working.
04:51:47 alex_xu HagunKim: you can use nova-manage db purge to purge the shadow table when you think those data is useless for you
04:52:50 HagunKim alex_xu: Because I use ocata version, I think I don't have purge command in nova-manage.
04:52:59 alex_xu HagunKim: ah
04:53:11 alex_xu HagunKim: probably you only can manually delete
04:53:29 alex_xu HagunKim: why there are duplicated data?
04:56:42 HagunKim alex_xu: Well.. I don't know why. But there are datas with same id value.

07:26:04 ileixe Hi nova!
07:26:42 ileixe Does anybody has an environment which assure CPU QoS within Nova?
07:27:18 ileixe I mean have anybody ever used CPU pinning in production or something else to prevent noisy neighbors?
07:28:16 ileixe I want to hear any experience which will be really appreciated for us
07:58:57 openstackgerrit ya.wang proposed openstack/nova master: Support reporting multi CPU model traits https://review.opendev.org/670300
08:19:55 openstackgerrit Matthew Booth proposed openstack/nova master: libvirt: Fix service-wide pauses caused by un-proxied libvirt calls https://review.opendev.org/677736
08:34:18 openstackgerrit Brin Zhang proposed openstack/nova master: Add delete_on_termination to volume-attach API https://review.opendev.org/673133
09:15:31 stephenfin alex_xu: Well, you can't migrate pinned instances at the moment anyway, so that's not an issue :)
09:16:10 stephenfin alex_xu: However, assuming artom fixes it, we have that option to disable the translation feature in the scheduler
09:16:27 stephenfin alex_xu: So if the operator sets that, the scheduler will keep requesting VCPUs
09:18:33 alex_xu stephenfin: okay, I thought people my blind to live migrate dedicated instance in case they have same hardware :)
09:18:51 alex_xu stephenfin: we don't have that option in the current version, right
09:19:22 alex_xu stephenfin: probably we can ask people live migration the instance before upgrade if they want
09:19:33 stephenfin No unless you explicitly set '[workarounds] enable_numa_live_migration'
09:19:36 stephenfin *Not
09:19:56 alex_xu oh, totally forget that option
09:20:17 stephenfin alex_xu: nah, if all they do is upgrade their compute nodes, nothing will change. They'll still be reporting and consuming VCPUs
09:20:55 openstackgerrit Gorka Eguileor proposed openstack/nova master: Use os-brick locking for volume attach and detach https://review.opendev.org/614190
09:20:57 stephenfin Things only change when the operator sets cpu_dedicated_set or cpu_shared_set on the controller, and set the as-yet-unnamed option on the controller
09:21:41 stephenfin when 'cpu_dedicated_set' is set, the compute node will start reporting PCPUs and transform existing inventory of pinned instances (if any) from VCPU to PCPU
09:21:50 alex_xu right
09:21:52 stephenfin not before that though
09:22:07 alex_xu stephenfin: so we still have that workaround option, in case people need it
09:23:31 stephenfin alex_xu: Yes, see https://review.opendev.org/#/c/671801/32/nova/conf/workarounds.py
09:23:42 stephenfin I'm going to have to rename and move that though, of course
09:24:35 bauzas stephenfin: you got hit by a merge conflict FWIW
09:24:36 bauzas https://review.opendev.org/#/c/671793/16
09:24:45 stephenfin yeah, I'll tackle that shortly
09:24:48 stephenfin expecting a lot of those
09:25:54 alex_xu stephenfin: ok, if the operator wants to upgrade the host os, then he can rolling upgrade the host os and nova-compute, without PCPU translating and cpu_dedicated_set. After all the nodes upgrade the new os and new nova-compute, then update the cpu_dedicated_set, to reshape the inventory, is that correct?
09:26:11 stephenfin yes
09:26:19 alex_xu so cool
09:26:44 alex_xu stephenfin: we really document those somewhere, like release note upgrade section?
09:27:28 stephenfin alex_xu: I've started here https://review.opendev.org/#/c/671793/16/releasenotes/notes/cpu-resources-d4e6a0c12681fa87.yaml
09:27:32 stephenfin But I'll add more as I go
09:27:38 bauzas alex_xu: yeah that's the plan
09:27:41 alex_xu stephenfin: cool
09:27:49 bauzas alex_xu: nothing changes unless the operator triggers it
09:28:07 alex_xu bauzas: yea, that is much simpler
09:28:08 bauzas but when they trigger, then it'll be a reshape
09:28:27 bauzas stephenfin: and that also implies we need to provide some nova-status check command
09:28:37 bauzas for upgrading to Unicorn
09:28:42 alex_xu stephenfin: also something fun https://review.opendev.org/#/c/674895/22/nova/virt/libvirt/driver.py, due to I updated a wrong option
09:29:18 sean-k-mooney alex_xu: dsid stephenfin answer your os upgrade question
09:29:31 alex_xu sean-k-mooney: yes, perfectly answered
09:30:59 gibi bauzas, stephenfin: hi! there are +2s from mriedem on the next couple patches in the support-move-ops-with-qos-ports series. starting here https://review.opendev.org/#/c/655110/
09:31:23 bauzas gibi: yeah, I was planning to put my eyes on your series after stephenfin's one
09:31:32 gibi bauzas: cool, thanks
09:44:39 yaawang stephenfin: alex_xu Hi, I had update the patches of vCPU models selection, can you take a look if you have time :) https://review.opendev.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/cpu-model-selection
09:45:27 alex_xu yaawang: got it, will check it again
09:45:49 yaawang alex_xu: thk :)
