#openstack-nova - 2017-01-27
18:01:01 cdent figleaf, jroll, johnthetubaguy: sorry guys I gotta go. I haven't eaten enough and starting to fade badly. If there's something I can do on sunday or in the UK morning monday, let me know, either by email to os-dev or direct to me.
18:02:01 jroll cdent: no worries man, I'll just leave anything I find on gerrit
18:02:09 jroll looks like it submits inventory correctly
18:02:10 johnthetubaguy cdent: figleaf: I am going to run soon too, similar comments about monday morning
18:02:28 cdent best of luck
18:02:42 johnthetubaguy jroll: well, not sure, once we get bauzas's change in, you will no longer be able to pick iroinc nodes if the current proposal merges
18:02:59 johnthetubaguy figleaf: I attempted to add a summary comment about what I think we should do
18:03:02 jroll johnthetubaguy: ... O_o
18:03:09 figleaf johnthetubaguy: cdent: ok, thanks for opening up this can of worms! (Seriously! It would have really sucked to let this out like this)
18:03:50 johnthetubaguy there may be 40% nonsense in my current suggestion, but lets see if that makes things clearer or not
18:05:17 jroll johnthetubaguy: lgtm, I think
18:06:22 johnthetubaguy figleaf: are you on board with the plan I sketched out in https://review.openstack.org/#/c/404472?
18:13:21 openstackgerrit John Garbutt proposed openstack/nova: Scheduler calling the Placement API https://review.openstack.org/417961
18:13:53 figleaf johnthetubaguy: sorry, working on a different fix atm. Looking now...
18:14:22 johnthetubaguy figleaf: so as I understood it, this is one of the two remaining FFEs, hence my focus on it
18:14:58 jroll fwiw I'm just getting lost in this code at this point
18:15:12 figleaf johnthetubaguy: I was thinking similarly - getting rid of the cleanup of old-style inventory
18:15:23 figleaf jroll: welcome to the club!!
18:16:05 figleaf johnthetubaguy: and trying to ensure that both old- and new-style can coexist
18:16:40 figleaf johnthetubaguy: and then add back the cleanup in Pike, remove it in Queens
18:16:54 johnthetubaguy figleaf: cool, yeah, I think we just report the new resources, for the first step
18:17:39 johnthetubaguy figleaf: yeah, the clean up can only be added after we start scheduling and claiming using the new resource class, I think, we can probably drop reporting the old ones at that point, but not 100% sure
18:18:30 johnthetubaguy actually the scheduling can happen first, then we can start claiming the new style, then we drop reporting the legacy resource classes
18:18:38 johnthetubaguy I think
18:23:51 openstackgerrit Dan Smith proposed openstack/nova: Avoid redundant call to update_resource_stats from RT https://review.openstack.org/424305
18:41:44 openstackgerrit Ed Leafe proposed openstack/nova: placement: RT now adds proper Ironic inventory https://review.openstack.org/404472
18:42:30 figleaf ^^ This just fixes the client bugs jroll found
19:15:41 openstackgerrit John Garbutt proposed openstack/nova: Added instance.reboot.error to the legacy notifications https://review.openstack.org/411816
19:29:26 bauzas superdan: johnthetubaguy: I'm now in the train back to Grenoble, what's the current situation for the scheduler change?
19:30:17 superdan bauzas: sdague wants the grenade change refactored, so I'm working on that
19:30:32 superdan bauzas: the scheduler thing passed multinode grenade before I started, johnthetubaguy was going to fix up the pep8 and unit tests
19:31:38 bauzas okay, thanks for both you
19:31:52 bauzas the pep8 issue is really easy
19:32:08 bauzas not sure I understand an unittest problem
19:32:08 sdague superdan: yeh, the placement add patch seems good now, pending tests
19:32:25 superdan sdague: I think it's still not working yet, but getting closer
19:32:36 sdague superdan: ok
19:32:48 superdan bauzas: see all the red FAILED on the patch
19:33:41 superdan I have to run out to meet someone in a little bit, but I will pick it up when I get back
19:33:56 superdan this person says they have a nice minimum wage job flipping burgers and I am SUPER INTERESTED
19:35:02 figleaf superdan: much less stress, for sure
19:35:34 superdan aye
19:48:58 bauzas oh man, the internet connection in the my train is so terrible :(
19:52:45 openstackgerrit Artom Lifshitz proposed openstack/nova: Pass APIVersionRequest to extensions https://review.openstack.org/425876
19:52:48 superdan well, it upgraded placement without exploding, we'll see if it actually works
19:53:43 bauzas superdan: so you modified grenade by adding a new placement service? heh, okay
19:54:03 bauzas I thought it was within nova, but fine by me
19:55:00 bauzas FWIW, I'd need to rebase the top patch since matt wrote a new PS for the bottom one
19:55:45 openstackgerrit Artom Lifshitz proposed openstack/nova: Pass APIVersionRequest to extensions https://review.openstack.org/425876
19:57:46 openstackgerrit Artom Lifshitz proposed openstack/nova-specs: Fix tag attribute disappearing https://review.openstack.org/426030
20:10:00 openstackgerrit Jim Rollenhagen proposed openstack/nova: DNM: hack ironic with resource providers https://review.openstack.org/426296
20:10:26 jroll figleaf: rebased that on your better patchset ^
20:10:55 figleaf jroll: working better?
20:13:44 jroll figleaf: I couldn't get it going for some reason, and dealing with other stuff since
20:13:56 jroll saw you uploaded that so figured I'd kick my test patch off at least
20:27:08 openstackgerrit Alex Szarka proposed openstack/nova: Transform instance.add_fixed_ip notification https://review.openstack.org/332876
21:28:48 superdan sdague: even though I did a bunch of work on that grenade patch are you cool with me +W when we've got a good run from the nova patch?
21:30:05 sdague superdan: the one I've got a +2 on?
21:30:10 sdague if so, yes
21:30:14 superdan sdague: yup
21:30:53 sdague yep
21:31:28 superdan thanks
21:59:45 diana_clarke superdan: What do you mean by "unmapped due to normally transient state"? https://github.com/openstack/nova/blob/e57714f9f162f60e77222b1ae8e1e78d2cb10a10/nova/cmd/manage.py#L1348
22:00:12 diana_clarke superdan: asking as I try to respond to this review feedback: https://review.openstack.org/#/c/421436/
22:09:46 superdan diana_clarke: like before it's scheduled
22:11:48 diana_clarke superdan: So return code 2 will eventually fix itself, correct? It has an instance mapping, just no cell mapping.
22:13:10 superdan diana_clarke: yeah
22:13:21 diana_clarke So perhaps that should read: "Returns 0 when the instance is successfully mapped to a cell, 1 if the instance is not mapped to a cell, and 2 if the instance is in the process of being mapped to a cell."
22:13:23 superdan it's a really small window
22:13:31 superdan sure
22:13:47 diana_clarke so return code 1 is an error case, right?
22:13:50 superdan I mean if you like less awesome comments
22:14:08 diana_clarke superdan: not changing your comment, trying to write the man page
22:14:10 diana_clarke ;)
22:14:20 superdan they both mean that the instance isn't functional,
22:14:48 superdan and 1 could be a transient case as well I think, let me think about it
22:14:50 superdan I know, I meant "awesome" in the snarky way
22:15:35 openstackgerrit Dan Smith proposed openstack/nova: Scheduler calling the Placement API https://review.openstack.org/417961
22:15:36 openstackgerrit Dan Smith proposed openstack/nova: Block starting compute unless placement conf is provided https://review.openstack.org/425806
22:16:33 superdan diana_clarke: okay, so from here forward, 1 is always an error, but not one we expect to happen, because:
22:16:33 diana_clarke Or asking differently (like johnthetubaguy), what action should be taken for return codes 1 & 2?
22:17:15 superdan in the past, we didn't have instance mappings, so if you have an instance in the database and no mapping, it was created on an older release and you didn't do your homework to patch up all the mappings yet
22:17:31 superdan so the point of that tool is really to verify that you created instance mappings for all of them
22:17:52 superdan however, if you run that while things are going on, you could get retval=2 due to a transient luck-based event
22:18:12 superdan but doing the online migrations should fix both cases up for any non-booting instances
22:18:29 superdan so the answer to "what to do" is run the map command
22:19:13 superdan map_instances for 1 and map_cell_and_hosts for 2 (modulo transientness)
22:19:17 superdan clear as mud?
22:21:13 diana_clarke superdan: I going to re-read that 10 times in a row, and then hopefully it will be ;) much appreciated!
22:21:45 superdan let me say it again linearly now that I have it in my head...
22:22:06 superdan If you get retval=1, that means you need to run map_instances as some instances (which were created with a previous version) don't have instance mappings yet
22:22:48 superdan if you get retval=2, that may be because you're racing with instances that are booting, or it may mean that you are missing cell mappings, which means you need to run map_cell_and_hosts
22:23:24 superdan someone could modify that code to not return 2 if the instance has a building-related task state such that we know it's the former case for retval=2
22:24:49 diana_clarke nice, thx!
22:43:57 openstackgerrit Ed Leafe proposed openstack/nova: placement: RT now adds proper Ironic inventory https://review.openstack.org/404472
22:44:29 figleaf johnthetubaguy: cdent: ^^ adds the workarounds for the problem we identified earlier.
22:48:26 mriedem_beach hola
22:48:55 mriedem donde esta el progresso?
22:49:12 superdan where is the progress?
22:49:21 mriedem si
