| 17:22:17 | sean-k-mooney | oh just read back you just upgraded? | |
| 17:22:39 | sean-k-mooney | i need to check one thing | |
| 17:22:44 | ygk_12345 | yes | |
| 17:22:49 | ygk_12345 | from stein to train | |
| 17:22:54 | ygk_12345 | one compute node is fine | |
| 17:23:02 | ygk_12345 | the rest three are having this problem | |
| 17:23:10 | ygk_12345 | not listing all the domains | |
| 17:23:28 | ygk_12345 | after a reboot | |
| 17:23:41 | ygk_12345 | i have to manually mount the lvm | |
| 17:23:54 | sean-k-mooney | ya so im not sure which release we changed it in but we fixed a bug with evacuation a couple of release ago where we did not properly clean up domains. but the side effect of that is if you did an evacuate and it failed and you did a reset state | |
| 17:23:55 | ygk_12345 | on to the /var/lib/nova/instances | |
| 17:24:13 | sean-k-mooney | then after upgrade the domain could be deleted | |
| 17:24:28 | ygk_12345 | but they are intact in one compute | |
| 17:24:47 | ygk_12345 | i still see the disk files with nova uuids present | |
| 17:24:53 | sean-k-mooney | it only affected instance where the operator incoorect did reset state | |
| 17:24:59 | ygk_12345 | but onl;;y virsh domains vanished | |
| 17:25:19 | sean-k-mooney | basically im wondering if the period jobs deleted the vms | |
| 17:25:25 | ygk_12345 | many vms went into ERROR state | |
| 17:25:35 | ygk_12345 | no such crons | |
| 17:26:06 | sean-k-mooney | ygk_12345: its not a cron job we have a period task in the nova compute agent | |
| 17:26:16 | ygk_12345 | ok | |
| 17:26:24 | sean-k-mooney | that looks for stale domains form evacuation or migratiosn and deletes them | |
| 17:26:25 | ygk_12345 | can we restore these vms now ? | |
| 17:26:44 | ygk_12345 | these were active vms before the upgrade | |
| 17:28:03 | ygk_12345 | i still see the active base files in the log for these vanished domaisn | |
| 17:28:59 | sean-k-mooney | yes but there are cases where they can be active because you did "nova reset-state" to put them in active but did not clean up migrations or evac | |
| 17:29:21 | ygk_12345 | no ididn't do any reset either | |
| 17:29:30 | ygk_12345 | i still see the base disk files intact | |
| 17:30:32 | sean-k-mooney | ygk_12345: you dont see a log message like this do you https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L9851-L9853 | |
| 17:31:15 | ygk_12345 | which message to be exact ? | |
| 17:32:13 | ygk_12345 | i see these vms in ERROR state | |
| 17:32:32 | sean-k-mooney | "Destroying instance as it has been evacuated from this host but still exists in the hypervisor ..." | |
| 17:32:57 | sean-k-mooney | or "Destroying instance with name label " | |
| 17:32:58 | sean-k-mooney | "'%s' which is marked as " | |
| 17:33:00 | sean-k-mooney | "DELETED but still present on host." | |
| 17:33:07 | ygk_12345 | nope | |
| 17:33:23 | ygk_12345 | its just in ERROR state | |
| 17:36:42 | sean-k-mooney | ok i was makeing sure it was not related too https://github.com/openstack/nova/commit/c4988cdabf311d29cf64af732091068cfabeedaa | |
| 17:36:58 | sean-k-mooney | which fixes https://bugs.launchpad.net/nova/+bug/1764883 | |
| 17:36:58 | openstack | Launchpad bug 1764883 in OpenStack Compute (nova) queens "Evacuation fails if the source host returns while the migration is still in progress" [Medium,Fix committed] - Assigned to Lee Yarwood (lyarwood) | |
| 17:37:22 | sean-k-mooney | but its not | |
| 17:38:22 | sean-k-mooney | that cause some vms in the active state to be deleted if operators incorrectly started an evacuation which failed and then reset the vm state. | |
| 17:38:57 | sean-k-mooney | ygk_12345: in this case im not aware of a bug that would result in the domains being deleted as part of a upgrade | |
| 17:39:43 | ygk_12345 | we did not evacuate. just upgraded from stein to train. one of the four computes is fine | |
| 17:40:09 | ygk_12345 | only virsh domains on these three computes vanished | |
| 17:40:14 | ygk_12345 | but the disk files are there | |
| 17:41:52 | artom | ygk_12345, so `virsh list` is empty? What about `virsh list --all`? | |
| 18:33:21 | sean-k-mooney | artom: it only has 2 domains out of like 30 | |
| 18:33:30 | sean-k-mooney | so something undefiend all the domains | |
| 18:33:59 | sean-k-mooney | and since the log message for the only code that i know of in nova that will do that is not present i dont really know why that happened | |
| 18:34:25 | sean-k-mooney | e.g. it was not the evac cleanup code or the preiodic take for deleted instances | |
| 18:35:02 | sean-k-mooney | so something undefiend the domains | |
| 18:39:08 | artom | sean-k-mooney, and since ygk are gone, we'll never know what happened :P | |
| 18:39:45 | sean-k-mooney | ya i dont really know how you woudl fix this either | |
| 18:40:03 | sean-k-mooney | i think the root disk files are already deleted | |
| 18:40:21 | sean-k-mooney | so im not sure there is much you can do at this point | |
| 21:59:15 | jharris | hey, I am trying to get a nova profile working, and having trouble with blockmapping | |
| 21:59:18 | jharris | do I need to put the image in the block mapping as well as the volume I want to mount? | |

| 09:38:33 | bauzas | good morning Nova | |
| 10:33:42 | stephenfin | lyarwood, bauzas: would you do me the honours? https://review.opendev.org/#/c/710238/ | |
| 10:34:12 | stephenfin | hahaha | |
| 10:34:18 | bauzas | "would you do me the homous" ? | |
| 10:36:45 | gibi | I got an interesting support case downstream. Does nova calculate the disk usage of its own image cache on the compute? | |
| 10:37:20 | stephenfin | gibi: I don't think nova includes anything except instances in those calculation | |
| 10:37:21 | stephenfin | *s | |
| 10:37:33 | gibi | all the non-nova disk usage should be configured in reserved_host_disk_mb | |
| 10:37:44 | stephenfin | I'd expect image cache to be included in the reserved host config | |
| 10:37:48 | stephenfin | yeah | |
| 10:38:00 | gibi | for that I would need to know the maximum size of the image cache | |
| 10:38:02 | bauzas | stephenfin: I'm not a multi-attach specialist | |
| 10:38:16 | bauzas | but I wonder why we were avoiding QEMU>2.10 | |
| 10:38:26 | gibi | do we have a way to maximize the size of the nova image cache? | |
| 10:38:38 | gibi | I mean limit | |
| 10:38:52 | stephenfin | bauzas: I think kashyap explained that to me at some point. Let me look | |
| 10:38:57 | stephenfin | it's a weird conditional, for sure | |
| 10:39:11 | stephenfin | gibi: I'm not aware of any, but I suspect there must be something. /me looks | |
| 10:39:48 | gibi | I tried to find it but I failed | |
| 10:39:57 | bauzas | stephenfin: yeah I suspect something was borked | |
| 10:40:12 | bauzas | but this whole comment is confusing | |
| 10:40:20 | bauzas | it's an "or" clause | |
| 10:40:36 | bauzas | so in theory, we should only support multiattach if QEMU<2.10 | |
