| 19:42:18 | mriedem | i just need to move the testing along, so i'm ok for now | |
| 19:44:57 | ildikov | mriedem: is there anything stvnoyes can help out or you're dedicated to make this one work? | |
| 19:45:35 | mriedem | i'm ok for now, wait until i'm stuck or don't have time to look | |
| 19:46:12 | stvnoyes | ok, that's fine. If there's something else I can help with, let me know. | |
| 19:46:19 | ildikov | mriedem: ok, cool, tnx | |
| 19:47:01 | mriedem | stvnoyes: have you read my comments in https://review.openstack.org/#/c/271047/ ? | |
| 19:47:04 | openstackgerrit | Chris Dent proposed openstack/nova master: Document lack of side-effects in AllocationList.create_all() https://review.openstack.org/530997 | |
| 19:47:17 | mriedem | could use more eyes on what, if any, restriction we're going to put in the compute api for multiattach and the new microversion | |
| 19:47:58 | stvnoyes | mriedem: i haven't looked at it yet. I'll take a look. | |
| 19:57:58 | mriedem | oh nice, | |
| 19:57:59 | mriedem | http://paste.openstack.org/show/637525/ | |
| 19:58:06 | mriedem | trying to attach a volume to more than one instance results in a 500 | |
| 20:01:05 | mriedem | Unable to create attachment for volume (Invalid volume: Volume 373c2a29-f6e7-4931-adda-6b87a193e9f9 status must be available or downloadi | |
| 20:03:42 | ildikov | mriedem: for a multiattach volume? | |
| 20:03:51 | mriedem | no, not multiattach | |
| 20:03:59 | mriedem | i wanted to make sure that still is prohibited | |
| 20:04:16 | openstackgerrit | Chris Dent proposed openstack/nova master: Fix documentation nits in set_and_clear_allocations https://review.openstack.org/531001 | |
| 20:04:37 | ildikov | oh, ok :) | |
| 20:08:53 | mriedem | hmm, why would i get a 400 in the case of os-reserve but a 500 from cinder in the case of attachment_create? | |
| 20:10:25 | mriedem | i would think the ResourceExceptionHandler would be used in both cases | |
| 20:10:33 | mriedem | that converts InvalidVolume to a 400 response | |
| 20:44:46 | openstackgerrit | Lance Bragstad proposed openstack/nova master: Simplify logic in get_enforcer https://review.openstack.org/531008 | |
| 20:55:10 | edleafe | mriedem: got a minute to talk about resize? | |
| 20:55:35 | mriedem | sure | |
| 20:56:42 | edleafe | we recently changed it to do 'replace_allocation_with_migration' to have the allocations use the migration uuid | |
| 20:57:19 | edleafe | It checks to verify that the instance is allocated against the source node, and if it isn't raises an error | |
| 20:57:57 | edleafe | But with claiming in the scheduler, select_destinations will claim against the target host | |
| 20:58:09 | edleafe | So the replace method always fails | |
| 20:58:56 | mriedem | edleafe: i can see that being true in the reschedule case, | |
| 20:59:12 | edleafe | exactly | |
| 20:59:16 | mriedem | because on the 2nd loop through conductor, the source node allocation will be held by the migration uuid and the first chosen and failed host is owned by the instance | |
| 20:59:33 | edleafe | (I forgot to mention that I'm working on functional tests for reschedules | |
| 20:59:50 | mriedem | ah - i was going to start working on a functional test this afternoon but got sidetracked with cinder | |
| 21:00:12 | mriedem | edleafe: so, we should (1) report a bug for the thing and (2) fix it separately before your alternate hosts patch for resize i think | |
| 21:00:17 | edleafe | I've been working on it, but it took a while to track down exactly why they were all failing | |
| 21:00:22 | mriedem | i was going to push the functional test before your alternate hosts patch in the series | |
| 21:00:39 | mriedem | yeah we need the functional resize + reschedule test regardless of alternate hosts | |
| 21:00:47 | mriedem | because it would have caught this earlier | |
| 21:00:55 | edleafe | makes sense | |
| 21:00:59 | mriedem | cool | |
| 21:01:23 | edleafe | so have you started on it? Should I wait and rebase on top of yours? | |
| 21:01:28 | mriedem | i haven't started | |
| 21:01:50 | mriedem | so feel free to report the regression bug and push a patch in nova/tests/functional/regressions | |
| 21:01:53 | mriedem | for that bug | |
| 21:02:06 | edleafe | ok, I can do it. I only have a little time left today, thanks to IBM adding a 2-hour each way commute to my schedule | |
| 21:02:24 | mriedem | how about report the bug and push what you have for the test | |
| 21:02:39 | mriedem | can work on a fix and such tomorrow | |
| 21:02:41 | edleafe | ok, I can do that. | |
| 21:02:44 | mriedem | thanks | |
| 21:05:38 | mriedem | i should probably start thinking about an rc1 bugs etherpad... | |
| 21:20:04 | openstackgerrit | Hongbin Lu proposed openstack/nova master: Handle not found error on taking snapshot https://review.openstack.org/511074 | |
| 21:26:02 | edleafe | mriedem: https://bugs.launchpad.net/nova/+bug/1741125 | |
| 21:26:03 | openstack | Launchpad bug 1741125 in OpenStack Compute (nova) "Instance resize always fails when rescheduling" [High,New] - Assigned to Ed Leafe (ed-leafe) | |
| 21:27:11 | mriedem | thanks; resize in general is probably just broken for the CachingScheduler | |
| 21:31:31 | mriedem | dansmith: we probably can't error out here https://github.com/openstack/nova/blob/f95f165b49fbc0efe29450b0e858a3ccadecedea/nova/conductor/tasks/migrate.py#L47-L48 | |
| 21:32:01 | mriedem | we won't have allocations if you're using the caching scheduler | |
| 21:32:35 | dansmith | hrm | |
| 21:33:27 | dansmith | and not create them either? that'll kinda screw with all the downstream logic for confirm/delete/undo-swap | |
| 21:33:29 | edleafe | if we do check, we should check against the instance or the migration | |
| 21:33:53 | mriedem | dansmith: compute won't create them once everything is pike+ | |
| 21:34:44 | dansmith | that's not what I meant, | |
| 21:35:00 | dansmith | but I guess we can't create the new allocations (on the dest) if we don't have some to copy from the source | |
| 21:35:03 | mriedem | edleafe: i think we can handle the logic in the conductor task based on whether or not we know we're doing a reschedule | |
| 21:35:41 | mriedem | edleafe: in the case of a reschedule, we'd swap the allocation from desthost1 to desthost2 for the migration uuid | |
| 21:35:51 | mriedem | and just leave the instance uuid allocation on the source node | |
| 21:36:34 | mriedem | not really a swap, just an update to the allocations for the migration consumer | |
| 21:37:29 | edleafe | yeah, I knew what you meant | |
| 21:39:16 | dansmith | reschedule of a migration is changing the instance uuid's allocation though not the migration one | |
| 21:39:45 | mriedem | oh right yeah, got those mixed up | |
| 21:39:55 | mriedem | migration stays on the source node, instance goes to the eventual dest host | |
| 21:40:01 | dansmith | so just need to update the instance's allocation for the new node | |
| 21:40:03 | dansmith | right | |
| 21:41:08 | melwitt | mriedem: what did you mean by your comment here? https://review.openstack.org/#/c/481700/7/nova/db/sqlalchemy/api.py@1867 update what, model_query? | |
| 21:42:43 | mriedem | the comment | |
| 21:42:51 | melwitt | oh, k | |
| 21:42:57 | mriedem | there is no 'deleted' in 'tags' or 'consoleauthtoken' tables | |
| 21:43:10 | melwitt | thanks | |
| 21:47:59 | mriedem | stvnoyes: got further on the multiattach tempest test; it appears to be failing to create the 2nd attachment | |
| 21:52:09 | openstackgerrit | Ed Leafe proposed openstack/nova master: Change compute RPC to use alternates for resize https://review.openstack.org/526436 | |

| 21:52:14 | edleafe | mriedem: ^^ resize reschedule func test | |
| 21:52:27 | mriedem | ok | |
| 21:58:37 | rybridges | Hey Guys! Had a really quick question. Is ephemeral GB included in snapshots for VMs? | |
| 22:58:16 | clarkb | I am pretty sure only the root device is snapshotted | |
| 22:58:27 | clarkb | (but I'm saying that as a user of random clouds not a nova dev that would know for sure) | |
| 23:19:36 | openstackgerrit | Merged openstack/nova master: Add test for assignment of uuid to a deleted BDM https://review.openstack.org/530774 | |

| 00:23:10 | mriedem | nailed it http://logs.openstack.org/67/529867/1/check/tempest-full/23d2919/controller/logs/screen-n-sch.txt.gz#_Dec_22_18_14_13_693048 | |
| 00:23:34 | mriedem | jaypipes: could you have guessed the stats / num_instances / host_state.instances stuff could have all gotten screwy? | |
| 00:26:58 | jaypipes | mriedem: not surprised. | |
| 00:31:00 | mriedem | heh "Reported number of instances (0) does not match the tracked number of instances (3)." | |
| 00:31:03 | mriedem | not even close | |
