| 17:52:36 | openstackgerrit | Matt Riedemann proposed openstack/nova stable/queens: Add policy rule to block image-backed servers with 0 root disk flavor https://review.openstack.org/563692 | |
| 18:01:53 | openstackgerrit | Matt Riedemann proposed openstack/nova stable/pike: Add policy rule to block image-backed servers with 0 root disk flavor https://review.openstack.org/563700 | |
| 18:16:13 | crazik | huh, finally. all services in pike. | |
| 18:16:25 | crazik | i was a looong and hard journey | |
| 18:16:27 | dansmith | mriedem: hmm, did you know a migration record can go into "pre-migrating" state because of the resource tracker? | |
| 18:17:05 | crazik | dansmith: or other issue | |
| 18:17:11 | crazik | like DB schema mismatch | |
| 18:17:17 | openstackgerrit | Matt Riedemann proposed openstack/nova stable/ocata: Add policy rule to block image-backed servers with 0 root disk flavor https://review.openstack.org/563719 | |
| 18:17:18 | dansmith | huh? | |
| 18:17:48 | dansmith | mriedem: I mean "will go" by the way | |
| 18:17:54 | mriedem | dansmith: i'm fairly sure that's on page 374 of the nova core handbook | |
| 18:18:34 | mriedem | why, what is it breaking? | |
| 18:18:49 | dansmith | mriedem: since you updated the comment above the list of filters, I challenge the fact that you knew that :P | |
| 18:19:11 | dansmith | mriedem: well, a migration can be in pre-migrating state, and thus neither of accepted or done, | |
| 18:19:18 | mriedem | what filters? | |
| 18:19:21 | dansmith | so the source compute may not find it if it comes up at the exact time | |
| 18:19:39 | dansmith | mriedem: https://review.openstack.org/#/c/500144/ | |
| 18:19:41 | mriedem | i assume you're referring to something else, like evac on startpu | |
| 18:20:03 | dansmith | yes, that's what I'm talking about | |
| 18:21:16 | mriedem | ok yeah i guess rebuild_claim will put the migration into pre-migrating status for evac | |
| 18:21:18 | dansmith | so it will go accepted->pre-migrating -> done -> completed | |
| 18:21:20 | dansmith | yeah | |
| 18:21:34 | mriedem | sorry i didn't have the full evac migration task state in my head when writing that comment... | |
| 18:21:45 | dansmith | well, I never knew it would do that | |
| 18:21:55 | dansmith | although I wonder if it would when I wrote that, because we did rebuild_claim recently, IIRC | |
| 18:22:30 | mriedem | as in 2015? https://review.openstack.org/#/c/200485/ | |
| 18:22:39 | dansmith | oh | |
| 18:22:58 | dansmith | I thought we added that while cleaning things up for placement, but maybe not | |
| 18:23:15 | mriedem | no, it was part of this https://review.openstack.org/#/q/topic:bug/1417667+(status:open+OR+status:merged) | |
| 18:23:42 | dansmith | yep, okay | |
| 18:24:00 | mriedem | i semi remember looking at that recently because of https://review.openstack.org/#/c/560467/ | |
| 18:24:23 | mriedem | and because we log a warning during every live migratoin | |
| 18:25:08 | mriedem | artom_: artom__: you might care about ^ | |
| 18:28:28 | artom | Sorry, moving around between rooms in the office :( | |
| 18:28:43 | artom | mriedem, thanks for the tip, I *would* care about that, but what's the context? | |
| 18:29:23 | mriedem | artom: RT claims code with live migration | |
| 18:29:27 | mriedem | which is now your thing | |
| 18:30:36 | artom | Sorta (see http://lists.openstack.org/pipermail/openstack-dev/2018-June/131605.html) | |

| 20:24:15 | anupn | Hi Folks, I am trying to schedule an instance over my baremetal node which is in "Available" state, but "host not mapped to any cell" error is coming upon scheduling an instance. Could you please point me how to map the host to the nova_cell1? | |
| 20:25:03 | anupn | I tried running "nova-manage db sync", and "nova-manage cell_v2 simple_cell_setup" but no luch | |
| 20:25:06 | anupn | *luck | |
| 20:25:31 | mriedem | anupn: see the discover_hosts command https://docs.openstack.org/nova/latest/cli/nova-manage.html#nova-cells-v2 | |
| 20:27:31 | anupn | mriedem: Yes I did, and I don't see any hosts there | |
| 20:27:55 | mriedem | did you run it with the --by-service option? | |
| 20:28:20 | openstackgerrit | Dan Smith proposed openstack/nova master: Fix MigrateData object tests for compat routines https://review.openstack.org/576256 | |
| 20:28:21 | dansmith | zcorneli: ^ | |
| 20:29:01 | zcorneli | dansmith: Was just looking at jaypipes suggestion for that. | |
| 20:29:43 | dansmith | zcorneli: basically just what I did | |
| 20:29:44 | anupn | mriedem: Nope, i ran without it and I got a user warning "UserWarning: The psycopg2 wheel package will be renamed from release 2.8......" | |
| 20:29:45 | dansmith | except better | |
| 20:30:00 | mriedem | anupn: well, try running with it, since it's for ironic nodes | |
| 20:30:08 | zcorneli | Yep. I like the lambda, makes it more clear, I think. | |
| 20:30:19 | anupn | mriedem: still the same | |
| 20:30:29 | dansmith | zcorneli: I spent my time writing code, else I'd have committed my comment before jaypipes :P | |
| 20:30:53 | anupn | mriedem: Should i run "nova-manage cell_v2 map_cell1"? | |
| 20:30:53 | mriedem | anupn: did you run it with --verbose to see if it actually mapped anything? | |
| 20:30:59 | mriedem | no | |
| 20:31:12 | zcorneli | dansmith: Do we want to follow his other suggestion as well, and do the associated AssertIn's? | |
| 20:31:14 | mriedem | unless the host is actually in some other db | |
| 20:31:22 | dansmith | zcorneli: I did | |
| 20:31:47 | dansmith | zcorneli: well, what I meant was, I added a positive assertion in each case | |
| 20:31:55 | anupn | mriedem: Okay so with --verbose, I see it finds two cells - cell0 and cell1 | |
| 20:32:00 | dansmith | zcorneli: no need to assert the presence of all the things for the latest version, IMHO | |
| 20:32:07 | dansmith | zcorneli: just one to make sure you're not looking at the wrong level of the structure | |
| 20:32:07 | anupn | it is skips cell0 as no hosts in that | |
| 20:32:42 | anupn | " | |
| 20:32:42 | anupn | Found 0 unmapped computes in cell: 182677b0-4e7d-416b-a47b-57c2f33e090e | |
| 20:32:42 | anupn | and from cell1 I see - "Getting computes from cell 'cell1': 182677b0-4e7d-416b-a47b-57c2f33e090e | |
| 20:33:01 | zcorneli | Seems like the positive assertion for every field is "clear" - It should be covered elsewhere in the tests as well, but ensures "It was there before making compatible, and not there after" | |
| 20:33:10 | mriedem | anupn: what does this give you? nova-manage cell_v2 list_hosts 182677b0-4e7d-416b-a47b-57c2f33e090e | |
| 20:33:19 | mriedem | does the compute host that's hosting that baremetal node show up in the list? | |
| 20:33:41 | zcorneli | dansmith: The single definitely helps fix the previous issue we had through with the false positives | |
| 20:33:50 | dansmith | right | |
| 20:34:14 | dansmith | zcorneli: you're welcome to positive-assert your property if you want, but I don't think it's that necessary | |
| 20:35:17 | anupn | mriedem: yes | |
| 20:35:26 | mriedem | anupn: ok so then the host is mapped to cell1 | |
| 20:35:32 | anupn | I see the hostname of my node | |
| 20:35:39 | mriedem | anupn: try scheduling now | |
| 20:35:54 | zcorneli | dansmith: I'm OK with the statement that the positive side is covered elsewhere. | |
| 20:36:38 | anupn | mriedem: Okay, wait but "openstack hypervisor list" shouldn't it show my ironic type hypervisor? | |
| 20:36:38 | openstackgerrit | Artom Lifshitz proposed openstack/nova master: DNM: Use claim context during live migration https://review.openstack.org/576222 | |
| 20:36:57 | mriedem | anupn: yes | |
| 20:36:59 | anupn | mriedem: oh yeah, it shows now | |
| 20:37:06 | mriedem | whew | |
| 20:37:16 | anupn | mriedem: so I think scheduling should work now | |
| 20:37:20 | mriedem | i hope so | |
| 20:37:28 | anupn | mriedem: what commands, made this magic? | |
| 20:37:34 | mriedem | discover_hosts --by-service | |
| 20:37:35 | mriedem | presumably | |
| 20:37:52 | anupn | mriedem: Ah, that's interesting, worth making a note | |
| 20:43:25 | anupn | mriedem: Instance got scheduled like charm :) | |
| 20:43:40 | anupn | thanks | |
| 20:44:26 | mriedem | anupn: cool, yw | |
