#openstack-nova - 2023-10-03
13:32:20 sean-k-mooney bauzas: i didnt say we will i said i wanted to get them ready before the ptg
13:32:34 bauzas okay
13:33:06 sean-k-mooney i would very strongly like to do this however
13:34:44 bauzas tbc, I'm okay with a new project, my only concerns are around to Nova
13:35:10 sean-k-mooney im mainly concerned about nova and our deliverables
14:56:00 atmark Hello! Yesterday, I upgraded Victoria to Wallaby using kolla-ansible. Out of 48 computes, I found 2 computes duplicated entries in `openstack compute service list`. It won't let me delete rouge entry
14:57:51 atmark I tried deleting the resource allocations and tried to do heal allocations but it throws an error
14:58:56 dansmith atmark: won't let you delete service records because why? it thinks they have instances running on them?
14:59:03 atmark dansmith: yes
14:59:45 atmark these are duplicate entries https://paste.openstack.org/show/bBM1U8uQkSgpsNh6gLFU/
15:00:03 bauzas reminder : nova meeting in 1 hour by now here
15:01:54 dansmith atmark: okay you'll want to find the instances that are assigned to the orphaned computes
15:02:12 dansmith I'm surprised to see that they have identical names
15:02:12 atmark compute01's nova-compute.log https://paste.openstack.org/show/bGYG9FcesMGyFRgYH08x/
15:04:39 opendevreview Merged openstack/nova-specs master: Amend spec to add more details around encryption secrets https://review.opendev.org/c/openstack/nova-specs/+/887905
15:06:02 dansmith huh okay I guess we can have duplicate hostnames in service records, even for the same binary
15:06:07 atmark dansmith: so I found the and tried to heal allocations but throws not descriptive `Error:` https://paste.openstack.org/show/bFSAcoAlJvZdpCrxzRyh/
15:06:23 atmark found the instances*
15:06:33 dansmith atmark: yeah that's not going to help because they have different nodes in the DB as well
15:08:00 dansmith atmark: so the best thing you can do, if able, is to migrate the affected instances away from the duplicate services and then delete the dupes after they're empty
15:11:51 atmark Cold migrate? Getting `No server with a name or ID of '' exists. when doing live migrate
15:12:17 dansmith any migration
15:12:39 dansmith is that the whole error message?
15:13:29 atmark yes, that's from the openstack client
15:15:27 opendevreview Merged openstack/nova-specs master: Re-propose using extend volume completion action for 2024.1 https://review.opendev.org/c/openstack/nova-specs/+/895648
15:15:58 dansmith like it's complaining about the instance id being unknown?
15:16:11 dansmith are you able to do a server show on that instance?
15:24:06 atmark dansmith: disregard the previous error, my for loop syntax to live migrate was wrong
15:24:20 atmark getting `Compute service of compute25.cnco1 is unavailable at this time.`
15:24:23 dansmith heh okay
15:24:46 dansmith atmark: is that just live or did you try cold as well?
15:24:53 atmark live
15:24:56 atmark let me try cold
15:25:43 dansmith so I think this might be because you've got these duplicated service records, so it's probably picking the wrong one.. usually what happens is people get duplicated *node* records, but the service record shows as up, so this works
15:26:25 dansmith picking the wrong one meaning it thinks the compute node is down even though it's not (obviously).. the migrating is what we need to correct the node mismatch, which you *also* have
15:26:34 atmark `Service is unavailable at this time.` for cold migrate
15:29:00 dansmith can you select out the host and node fields for one of the affected instances direct from the database?
15:35:22 atmark dansmith: https://paste.openstack.org/show/b0oiRoqWDHHgataIK7jO/
15:37:40 dansmith atmark: and can you query out the relevant records from services and compute_nodes?
15:38:22 dansmith it's weird that the compute is having trouble finding the right compute node record (placement errors in the compute logs) and that the instance is being associated with the downed duplicate service record
15:38:29 atmark these are instances affected https://paste.openstack.org/show/bM6wA9HPHbuNzGmNEqPB/
15:39:28 dansmith yeah so just a little background, we associate instances, nodes and services very loosely with these hostnames, which is terrible and fragile, as you're noticing.. work has been done recently to try to make this better (if that's any consolation)
15:43:13 atmark services and compute_nodes table https://paste.openstack.org/show/bujkfzse6gko5nV197ue/
15:44:24 dansmith hmm, okay, so there is only one non-deleted service of each name right?
15:44:55 dansmith a record is deleted when there is a non-zero value in the deleted column
15:47:08 dansmith I'm not sure why you're seeing them in the services list through the openstack client in that case
15:47:31 atmark for compute01, I ran `openstack resource provider allocation delete $consumerid`, deleted the resource provider for the compute, restarted the nova compute to let it recreate resource provider entry a
15:47:58 atmark upon healing allocation, it wont just throws an error
15:48:13 atmark it just throws an non descriptive error*
15:48:34 dansmith yeah, well (a) you shouldn't have done that but (b) I think it's failing to create a new provider with the same name
15:49:12 dansmith also that has nothing to do with these records, FWIW
15:49:22 dansmith atmark: your compute nodes list doesn't show the deleted field, can you update with that field?
15:50:26 atmark https://paste.openstack.org/show/b6Ng2S3XwYQoL8G0mJvr/ with deleted field
15:52:57 dansmith so the uuid in our compute01 logs shows a node uuid of bf7a7e8e-c486-42b2-8dc4-00b2d5f70f86
15:53:08 dansmith but I don't see that in your nodes list
15:53:15 dansmith can you see if any compute node has that uuid in the DB?
15:53:24 dansmith atmark: I guess I should also ask - do you have multiple compute cells?
15:53:49 atmark (a) - I followed what's in RH KB https://access.redhat.com/solutions/5308941. After the upgrade, nova-compute on those was throwing `Conflicting resource provider name`
15:54:33 dansmith are you running OSP?
15:55:03 atmark atmark: Yes, two cells: cnco1 and cnco2 but I only use cnco1 cell
15:55:35 atmark dansmith: No. I have kolla-ansible deployment
15:55:39 dansmith meaning there are no compute nodes in the other cell? but it's mapped?
15:56:08 atmark show databases https://paste.openstack.org/show/b26YFJxzw33hNLa9pVLw/
15:56:22 opendevreview Elod Illes proposed openstack/nova stable/victoria: libvirt: Abort live-migration job when monitoring fails https://review.opendev.org/c/openstack/nova/+/837321
15:56:39 dansmith re: cells I'm just trying to suss out if there are any duplicates happening because of that.. can you check the services table in the other cell to see if any of them have the same hostname of either of these affected ones just to be sure?
15:56:42 atmark nova_cnco1 is where all computes are mapped
15:57:29 dansmith atmark: we're going to have to pause here for the compute meeting in a few minutes but if you're still around after we can resume
15:57:53 atmark got it
15:57:57 atmark appreaciate the help
15:58:33 atmark re: can you check the services table in the other cell - nova_cell0?
15:59:57 dansmith no you said you have a cnco2 cell
16:00:01 atmark nova_cell0 https://paste.openstack.org/show/by9WvQgKARdZRppniRoY/
16:00:06 dansmith cell0 is a different thing
