| 19:23:35 | melwitt | I think so | |
| 19:23:43 | sean-k-mooney | im wonderign if that should go to the end with an api check? or if your confidnet we can merge that | |
| 19:24:33 | sean-k-mooney | ok then lets try and minimise the code curn by keepign the order and addign functional tests either inline or as followups at the end where you feel it fits best | |
| 19:24:59 | melwitt | it could. it's pretty simple really, the thing migrations needed to work is to have the libvirt secrets available on the destination and until that patch it wasn't creating them on the dest (and deleting them on the source) | |
| 19:25:23 | sean-k-mooney | ah ok | |
| 19:25:40 | melwitt | I've been trying to cut things down as small as possible because this stuff is complicated imho | |
| 19:26:00 | sean-k-mooney | i ran out os steam this morning but my goal is ot have reviewd each patch at least once by the end of the week | |
| 19:27:08 | melwitt | ack. I'm trying to get the next rev pushed sometime today/tonight | |
| 19:30:00 | sean-k-mooney | ok if you dont its not the end of the world. much of the content will be the same so i can still review to some degree | |
| 19:30:59 | melwitt | ack | |
| 20:00:59 | sean-k-mooney | ok i think its time for me to finish for today | |
| 20:01:05 | sean-k-mooney | o/ | |

| 00:31:13 | tonyb | Thanks to sean-k-mooney[m] I managed to reduce the list of stale/stuck/corrupt VMs from 28 to 12 (It took a while because I was *very* careful with my db manipulations) | |
| 00:32:37 | tonyb | Now I have 12 instances that are in the building/scheduling vm/task state. | |
| 00:33:23 | tonyb | Some have entries in nova_api.instace_mappings pointing at cell0 some at the real cell (which has a NULL name?) | |
| 00:34:41 | tonyb | AFAICT the instances don't have any allocations in placement | |
| 00:35:43 | tonyb | What is the "most correct"/"least horrible" DB update I can do to let nova know those instances are gone? | |
| 00:39:07 | tonyb | I was thinking of something like update instances set vm_state='ERROR', set task_state=???, set updated_at=now(), set deleted_at=now() where uuid in (....) ? | |
| 02:17:20 | clarkb | tonyb: I wonder if we just set vm state to active if a delete woudl work | |
| 03:16:51 | tonyb | I didn't try that. | |

| 08:37:23 | sean-k-mooney[m] | tonyb: to mark an instance as deleted in nova you set deleted=id | |
| 08:38:06 | tonyb | thanks that's basically what I did. | |
| 08:39:01 | sean-k-mooney[m] | so there is no way to take an instance from cell 0 and do anything other then delete it | |
| 08:39:32 | sean-k-mooney[m] | cell0 is basically a gravyard for instnce we were unable to boot | |
| 08:39:54 | sean-k-mooney[m] | and they should not have any allocaations in placement if they are in cell 0 | |
| 08:40:19 | sean-k-mooney[m] | for the ones in schduling they have not had a host selected so they willl not be in any cell db | |
| 08:40:33 | sean-k-mooney[m] | they will just have a build request in the api db | |
| 08:41:06 | sean-k-mooney[m] | the ones in the real cell in building likely failed because of the rabbit outage | |
| 08:41:40 | sean-k-mooney[m] | i assume you just want them gone so you can boot new vms with nodepool | |
| 08:42:05 | tonyb | yup that's the aim. I did get rid of them | |
| 08:42:58 | sean-k-mooney[m] | if they are in building and are in a really cell then they likely have allocations so you would mark them as deleted in the cell db then delete there allocations in placement | |
| 08:43:15 | sean-k-mooney[m] | ok in that case are they all now cleanned up? | |
| 08:43:57 | tonyb | yup. I did discover some other nodes that have allocations but are gone. | |
| 08:44:25 | tonyb | I'll figure that out tomorrow, but it should be easy to find them in placement | |
| 08:44:33 | sean-k-mooney[m] | we have two related command nova-manage heal allocatiosn and audit | |
| 08:44:48 | sean-k-mooney[m] | the heal allocation command creates alloctions that are missing | |
| 08:45:04 | sean-k-mooney[m] | the audit command removes allocatons that should nolonger exist | |
| 08:45:15 | tonyb | oh! cool. | |
| 08:45:17 | sean-k-mooney[m] | and has a dry run mode by default that just prints them | |
| 08:45:37 | tonyb | that's perfect for tomorrow! | |
| 08:45:59 | tonyb | sean-k-mooney[m]: thanks for all your help | |
| 08:46:16 | sean-k-mooney[m] | https://github.com/openstack/nova/blob/stable/victoria/nova/cmd/manage.py#L2695 | |
| 08:52:23 | tonyb | sean-k-mooney[m]++ | |
| 09:14:59 | gibi | elodilles, sean-k-mooney[m]: could you check these backports please https://review.opendev.org/q/topic:%22power-mgmt-fixups%22+branch:stable/2023.2 | |
| 09:15:09 | gibi | the master revert landed yesterday (finally) | |
| 09:15:40 | sean-k-mooney[m] | sure just reviewing one of mels patchs ill look at those next | |
| 09:19:10 | gibi | thanks | |
| 09:28:39 | bauzas | sean-k-mooney: gibi: got some devstack issue with ovn, because the package is missing | |
| 09:28:49 | bauzas | (RHEL9.3 here) | |
| 09:29:15 | sean-k-mooney[m] | its in a seperate repo call fast datapath on rhel | |
| 09:29:17 | bauzas | when looking at https://github.com/openstack/devstack/blob/master/tools/fixup_stuff.sh I see that centos9 installs centos-release-openstack-victoria package | |
| 09:29:21 | sean-k-mooney[m] | our you can just enabel the rdo repos | |
| 09:29:46 | sean-k-mooney[m] | i can give you the command for the rdo repos one sec | |
| 09:29:56 | bauzas | I can insdtall rdo-ovn | |
| 09:30:06 | bauzas | it says this is a wrapper for OVN | |
| 09:31:29 | sean-k-mooney[m] | https://github.com/openstack-k8s-operators/edpm-ansible/blob/28f80d2303497972a1d3b493760c4ff1557b973f/roles/edpm_nova/molecule/default/prepare.yml#L40 | |
| 09:31:41 | sean-k-mooney[m] | if you dont have the repos then i belive that will fix it for you | |
| 09:32:18 | sean-k-mooney[m] | change -b antelope to master | |
| 09:32:43 | bauzas | https://paste.opendev.org/show/b95bS56avBrLTeoma0QU/ | |
| 09:32:53 | bauzas | that's what I have | |
| 09:33:30 | sean-k-mooney[m] | ok then devstack already enabled rdo for you | |
| 09:33:38 | bauzas | correct | |
| 09:33:43 | sean-k-mooney[m] | how did it fail exactly | |
| 09:34:02 | sean-k-mooney[m] | you could just go back to ml2/ovs by the way | |
| 09:34:14 | sean-k-mooney[m] | but if you want to keep ovn | |
| 09:34:24 | bauzas | https://paste.opendev.org/show/bkHbTVtFyFTMA34VV1B7/ | |
| 09:34:30 | sean-k-mooney[m] | i can take a look at the error with you in a few minutes | |
| 09:34:46 | bauzas | yeah I think I'll change my local.conf and play with ml2/ovs | |
| 09:35:25 | bauzas | (my local.conf is pretty simple, nothing is told about the networking) | |
| 09:35:44 | sean-k-mooney[m] | oh its the metadata agent not ovn | |
| 09:36:49 | sean-k-mooney[m] | you can always just trun that off and use config drive | |
| 09:37:05 | bauzas | that's my local.conf https://paste.opendev.org/show/bwqKtvfeZhUT9aL1kFoZ/ | |
| 09:37:39 | sean-k-mooney[m] | https://github.com/openstack/nova/blob/master/.zuul.yaml#L192-L201 | |
| 09:37:49 | sean-k-mooney[m] | that is how to swap to ml2/ovs | |
| 09:38:57 | bauzas | q-ovn-metadata-agent.service that's the service which failed | |
| 09:39:12 | sean-k-mooney[m] | oh you need https://github.com/openstack/nova/blob/master/.zuul.yaml#L186-L189 as well | |
| 09:39:27 | bauzas | oh wait, I have ovn installed | |
| 09:39:33 | sean-k-mooney[m] | yes | |
| 09:39:43 | sean-k-mooney[m] | its the neturon metadata agent for ovn that failed | |
| 09:39:52 | sean-k-mooney[m] | not the ovn install | |
| 09:40:00 | bauzas | yeah | |
| 09:40:14 | bauzas | I can try to dig into the logs of that agent, if I'm able to find them | |
| 09:40:27 | sean-k-mooney[m] | they are in the journal like all the rest | |
| 09:40:41 | sean-k-mooney[m] | so just journalctl -u devstack@whatever | |
| 09:41:31 | sean-k-mooney[m] | im stepping away for 5-10 minutes to grab coffee but when im back if you want me to ssh in and take a look with you i can | |
| 09:41:50 | bauzas | yeah | |
| 09:41:55 | bauzas | and thanks | |
| 09:48:58 | bauzas | ahah, found the culprit https://paste.opendev.org/show/bFigNVupZWRpjlmuzXZ9/ | |
| 09:50:21 | sahid | o/ regarding live migrations, we are agree that we can live-migrate vm from compute node that are N-1 to N ? | |
| 09:50:53 | sahid | in a situation of upgrading version of openstack | |
| 09:53:49 | bauzas | sure, not the other way | |
| 09:58:10 | sahid | ack thanks | |
| 10:12:56 | sean-k-mooney | bauzas: ah the privsep helper | |
| 10:13:36 | sean-k-mooney | bauzas: so tht issue is that its not on your path | |
| 10:13:59 | sean-k-mooney | bauzas: i put a path fix in devstack to fix that at one point | |
| 10:14:41 | bauzas | /usr/bin/which: no privsep-helper in (/opt/stack/.local/bin:/opt/stack/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin) | |
| 10:14:41 | bauzas | [stack@lenovo-sr655-01 devstack]$ which privsep-helper | |
