| 15:16:27 | mnaser | vs seeing it as disabled is pretty obvious to an operato | |
| 15:20:06 | sean-k-mooney | operator feedback was why we change this | |
| 15:20:24 | sean-k-mooney | i tought the old behavior was the correct one | |
| 15:20:57 | sean-k-mooney | i.e. disabling the service ideally with the reason to something the operator would consume | |
| 15:23:49 | sean-k-mooney | mnaser: by the way you shoudl be abel to force that host to be used currently | |
| 15:24:02 | sean-k-mooney | it just wont get selected byt the schduler if there are other options | |
| 15:24:11 | mnaser | sean-k-mooney: well this explains the whole story why when guilhermesp_ tried to spin up a vm on it | |
| 15:24:17 | mnaser | it started accepting requests right away | |
| 15:24:21 | sean-k-mooney | one thing i had considered in the past was having this time out in some way | |
| 15:24:24 | mnaser | it probably reset the failure counter to 0 and its all good to go | |
| 15:24:34 | sean-k-mooney | yep | |
| 15:24:36 | sean-k-mooney | it would have | |
| 15:25:19 | mnaser | this doesnt explain why i was getting the port plugging timeouts that caused this but | |
| 15:25:31 | mnaser | at least this wont just bring a whole bunch of systems out of being scheduled for an extended period of time | |
| 15:25:39 | sean-k-mooney | well the neutron agent on that host might have hadd issues | |
| 15:26:09 | sean-k-mooney | and perhpase they have now been resovled? | |
| 15:26:19 | mnaser | sean-k-mooney: yeah but it's happening across different systems so its a common thing | |
| 15:26:23 | mnaser | and on a stuck box i saw this once | |
| 15:26:24 | mnaser | Agent rpc_loop - iteration:1192598 - ports processed. Elapsed:6685.721 | |
| 15:26:36 | mnaser | 1.85h for the rpc loop? :) | |
| 15:26:46 | sean-k-mooney | nice | |
| 15:26:50 | sean-k-mooney | must be a record | |
| 15:26:59 | mnaser | lol yup | |
| 15:27:17 | mnaser | so i think tehre is something in the interaction between ovs and n-ovs-agent that just started the domino effect | |
| 15:27:27 | sean-k-mooney | what os-vif driver are you usign by the way | |
| 15:27:34 | sean-k-mooney | the navie one or vsctl | |
| 15:28:02 | mnaser | i believe vsctl right now | |
| 15:28:10 | mnaser | i think we should probably flip that over to native at some point soon | |
| 15:28:11 | sean-k-mooney | ya so the reason i brought os-vif up is the ovs python bindings have a bug which i hope is now fixed | |
| 15:28:56 | sean-k-mooney | basically the ovs python bindings actuly made un monkeypatched poll socket calls | |
| 15:29:13 | sean-k-mooney | that could lock up nova when there was a disconnect until it reconnected | |
| 15:29:51 | sean-k-mooney | i think neutron have work around that but depned on the release | |
| 15:30:35 | mnaser | yeah i managed to pull a gmr when neutron was stuck for ~2h | |
| 15:30:50 | sean-k-mooney | mnaser: what release | |
| 15:31:00 | sean-k-mooney | im just checkinng for the neutron workaround | |
| 15:31:39 | mnaser | victoria, i think we're waiting for a few things before going to wallaby (but this is wallaby nova + victoria n-ovs-agent) | |
| 15:32:54 | mnaser | this is part of the culprit https://www.irccloud.com/pastebin/nxc0Uknt/ | |
| 15:33:25 | sean-k-mooney | https://review.opendev.org/c/openstack/neutron/+/794892 | |
| 15:33:53 | sean-k-mooney | i wonder if they only fixed ovn | |

| 15:34:49 | sean-k-mooney | i dont see it here https://github.com/openstack/neutron/blob/57f9822a8b398e92d1efebd85a1bdd4f9b27b046/neutron/agent/ovsdb/impl_idl.py | |
| 15:36:13 | sean-k-mooney | os-vif does it but only if you are using the native imple | |

| 15:37:27 | mnaser | sean-k-mooney: i mean technically since neutron polls so often it might as well be a keepalived | |
| 15:38:39 | sean-k-mooney | so this is worign aroudn a bug in the ovs python bindings | |
| 15:38:57 | sean-k-mooney | we basically trun off the heartbeat | |
| 15:39:02 | sean-k-mooney | and rely on tcp keepalive | |
| 15:39:38 | sean-k-mooney | https://bugs.launchpad.net/os-vif/+bug/1929446 | |
| 15:41:01 | sean-k-mooney | the issue has been fixed in python-ovs 2.16 | |
| 15:41:08 | sean-k-mooney | based on https://review.opendev.org/c/openstack/ovsdbapp/+/818446 | |
| 15:41:24 | sean-k-mooney | the os-vif and neutron fixes were mitigations | |

| 08:24:28 | gibi | sean-k-mooney: when you are up. We can go through the open questions in the PCI tracing spec | |
| 09:10:21 | ralonsoh | gibi, qq if you know that. For live-migration, all libvirt should have the same "virsh secret-list" ? | |
| 09:14:15 | gibi | ralonsoh: o/ good question. I guess you are looking at a situation with encrypted volumes | |
| 09:15:00 | ralonsoh | gibi, yes, I've deployed two nodes with devstack and ceph | |
| 09:18:12 | gibi | hm, I dont seem to find any code in nova that would move the secret | |
| 09:27:41 | gibi | I'm not a sure how this works but seems like barbican is involved too | |
| 09:31:52 | gibi | ralonsoh: as melwitt took over the ephemeral encryption work from lyarwood I expect that she might know more about the volume encryption case as well | |
| 09:32:20 | ralonsoh | gibi, thanks, I'm going to try to deploy this env without encription, if possible | |
| 09:42:59 | opendevreview | Jorhson Deng proposed openstack/nova master: Clear the ignore_hosts before starting evacuate https://review.opendev.org/c/openstack/nova/+/841089 | |
| 09:43:20 | sean-k-mooney | do you mean the ceph secret | |
| 09:43:35 | sean-k-mooney | if so we expect the operator to distibute that | |
| 09:43:57 | ralonsoh | sean-k-mooney, this is in a devstack installation | |
| 09:44:25 | sean-k-mooney | yep | |
| 09:44:47 | ralonsoh | so one compute is requesting its own secret id | |
| 09:45:00 | ralonsoh | and the other compute is asking for other | |
| 09:45:13 | ralonsoh | and I don't know it that should match the ceph.conf fsid | |
| 09:50:25 | sean-k-mooney | hum i could try and deploy this and see. but the devstack roles just copy the keyfiels and config to the compute https://github.com/openstack/devstack/blob/master/roles/sync-controller-ceph-conf-and-keys/tasks/main.yaml | |
| 09:50:54 | sean-k-mooney | then on the compute you set REMOTE_CEPH=True | |
| 09:51:05 | ralonsoh | sean-k-mooney, yes, that's set | |
