#openstack-nova - 2018-01-23
14:23:55 rgerganov cdent, you mean that we can't have VCPU in both parent and childs?
14:23:57 mriedem jroll: nope
14:24:23 alex_xu gibi: thanks, will try to submit a separate followup tomorrow
14:24:24 jroll yay
14:24:48 cdent rgerganov: it can be in both places, but they cannot overlap. Any inventory of the same type associated with the child provider needs to be subtracted from the parent.
14:25:03 mriedem Roamer`: i still have the tab open
14:25:13 rgerganov cdent, this is not the problem that I have now
14:25:30 rgerganov cdent, when you start nova-compute udpate_provider_tree is being called twice
14:25:37 cdent rgerganov: yeah, I get that, was just noting it for future reference
14:26:03 cdent first in init and then in the periodic job?
14:26:54 rgerganov cdent, both calls come from _update_available_resource in the RT
14:28:08 rgerganov cdent, on the first call the provider tree seems to be correct and both parent and child RP are updated in placement
14:28:23 rgerganov cdent, on the second call I get 409 from placement
14:28:31 gibi alex_xu: I'm +2 on the last patch too, thanks for the reno
14:28:41 alex_xu gibi: thanks for the review!
14:29:15 rgerganov cdent, because it tries to create the nested RP again
14:29:36 cdent rgerganov: how close together are those jobs, by timestamp?
14:30:19 rgerganov cdent, they are far away because I am tracing the code
14:30:39 rgerganov cdent, like couple of seconds away
14:30:56 cdent It seems like the provider tree isn't getting a chance to update its cache of the rp generation
14:31:05 rgerganov cdent, correct
14:31:35 cdent It behaves the same way with the debugger not involved?
14:31:43 rgerganov yes
14:32:07 rgerganov on the first call the provider tree has both parent and child and the call to placement succeds
14:32:53 rgerganov on the second call it has only the parent and when the driver adds the child and placement is called, we get 409
14:34:44 cdent rgerganov: and the message with the 409 is what?
14:35:24 rgerganov cdent, Failed to create resource provider record in placement API for UUID 4be176f1-b09f-48dd-82d7-d9c1c86fb68b. Got 409: {"errors": [{"status": 409, "request_id": "req-69d31b34-bc50-4178-a569-ebaef4734cbd", "detail": "There was a conflict when trying to complete your request.\n\n Conflicting resource provider name: vdc already exists. ", "title": "Conflict"}]}.
14:37:00 cdent rgerganov: thanks, looking at the calling code now
14:44:47 edmondsw gibi tx for reviewing the powervm SEA patch! Are you planning to look at the powervm vscsi patch as well?
14:45:02 openstackgerrit Jackie Truong proposed openstack/nova master: Add trusted_certs object https://review.openstack.org/489408
14:45:02 cdent rgerganov: on the second request, when the provider tree doesnt have the child, have you traced what's happening in _ensure_resource_provider. It seems like in there is where it could be going awry and not creating a full tree
14:46:05 gibi edmondsw: I cannot promise that it will fit before the feature freeze
14:47:19 edmondsw gibi ok. If you get to it, thanks. If not, maybe someone else will
14:48:55 gibi edmondsw: please ping me daily, that will help me not to forget
14:49:28 edmondsw gibi you asked for it... ;)
14:49:34 edmondsw thanks
14:50:55 edmondsw stephenfin do you also want daily reminders? ;)
14:50:58 gibi :)
14:51:22 stephenfin edmondsw: Nope, it'll be done :)
14:51:33 openstack bugzilla.redhat.com bug 1534669 in openstack-nova "emulator_threads_policy needs improvement when hyper threading is enabled" [Medium,New] - Assigned to sfinucan
14:51:43 edmondsw stephenfin thanks!
14:51:56 rgerganov cdent, correct, this method doesn't fetch the full tree on the second call
14:52:13 rgerganov cdent, self._refresh_associations doesn't do what we expect
14:58:34 edmondsw bauzas johnthetubaguy any chance you could look at https://review.openstack.org/#/c/526094/ adding powervm cinder volume support?
15:02:31 openstackgerrit Jackie Truong proposed openstack/nova master: Add trusted_image_certificates to REST API https://review.openstack.org/486204
15:03:43 mriedem melwitt: want to hit this 3 LOC patch for 2.60 support in novaclient? https://review.openstack.org/#/c/536621/
15:09:45 melwitt mriedem: got it
15:09:47 bauzas mriedem: I can look
15:09:54 bauzas heh, snap
15:10:12 mriedem thanks, that'll likely be it for queens
15:14:39 openstackgerrit Matt Riedemann proposed openstack/osc-placement master: Usage docs and initial release note for osc-placement https://review.openstack.org/536858
15:16:39 openstackgerrit int32bit proposed openstack/nova master: Set server status to ERROR if rebuild failed https://review.openstack.org/536268
15:22:14 openstackgerrit Jackie Truong proposed openstack/python-novaclient master: Microversion 2.61 - Add trusted_image_certificates https://review.openstack.org/500396
15:25:50 alex_xu mriedem: in case you have time https://review.openstack.org/#/q/topic:bp/request-traits-in-nova+(status:open+OR+status:merged), I have last two patches waiting for one more +2, appreciate if you can help it
15:27:56 mriedem alex_xu: ok, also looks like https://review.openstack.org/#/c/536083/4/nova/scheduler/client/report.py overlaps with something dansmith was working on
15:28:05 mriedem to use the 1.12 allocation candidates format for the move operations in the report client
15:29:40 dansmith mriedem: I think that patch just has two remaining failures to look at but I've been kinda absorbed with other things lately
15:31:43 melwitt mriedem: on the set status to ERROR upon rebuild failure patch, do you think it would be worth adding a fault message to the instance along with the ERROR state? I was thinking since the instance is sitting with the wrong imageref, it might be helpful to give some guidance in the fault message in case someone doesn't know how to recover https://review.openstack.org/#/c/536268/
15:32:50 sean-k-mooney stephenfin: for the record that refactor is annoying. i have all but 1 test passing now howerver the pci request spec object has like 8 required field not just the 4 in the alias schema definition
15:32:54 mriedem yeah a fault is probably necessary, i thought we'd have one on there but apparently we only use wrap_instance_fault in the compute manager
15:33:14 stephenfin sean-k-mooney: Really? What are the other ones?
15:33:48 dansmith melwitt: so can you push up a change to add a fault so we can get moving on that?
15:34:07 sean-k-mooney stephenfin: http://paste.openstack.org/show/650978/
15:34:26 melwitt dansmith: yep, let me do that
15:34:44 sean-k-mooney stephenfin: the commented out ones should be deleted
15:35:20 dansmith melwitt: cool
15:35:48 sean-k-mooney stephenfin: also i found that some test use device_id instead of product id so i have to support both and while the alias uses device_type the db uses dev_type so i have to convert when i create the spec
15:37:00 stephenfin sean-k-mooney: You can probably drop capability_type
15:37:06 sean-k-mooney stephenfin: anyway when i get the last test passing ill push up the new revision.
15:37:12 stephenfin Per my comment in nova/pci/request.py
15:37:40 stephenfin But otherwise, yeah, I figured it wouldn't be super easy but it is a much better design long-term, IMO
15:37:44 sean-k-mooney stephenfin: nope you will get an invalid key exception unless i specificlally add code to drop it
15:38:12 stephenfin sean-k-mooney: I'm working through the CPU pinning code again. Every time I go through this, I have to relearn it
15:38:34 stephenfin sean-k-mooney: But nothing except tests use it
15:38:36 stephenfin *set it
15:39:17 stephenfin and we could just filter it out of any '[pci]spec' options with a warning that it must be manually removed
15:39:20 damini 111Pls can anyone tell me how to write tempest test for shelve instance and unshelve .I am new to openstack.
15:39:50 sean-k-mooney haha well now you mention it the code that is failing is in consume_requests a pop from an empty list.
15:40:17 sean-k-mooney stephenfin: ya its easy to ignore it and log a message the way i have it set up instead of a exception
15:41:49 stephenfin damini: Tempest has a helper function for that. You might want to start there https://github.com/openstack/tempest/blob/master/tempest/common/compute.py#L263
15:42:26 stephenfin sean-k-mooney: (y) that would be my recommendation
15:42:34 alex_xu dansmith: do you have the link? I didn't found in the gerrit
15:42:39 stephenfin No point adding something we're going to immediately deprecate
15:42:49 dansmith alex_xu: link for what?
15:43:17 alex_xu dansmith: the 1.12 which mriedem mentioned, I guess you hit 1.12 by this patch https://review.openstack.org/#/c/531517/2
15:43:53 mriedem yeah that's the one
15:46:11 alex_xu mriedem: ah, I got it, dansmith already said he is working on other things. sorry, i misunderstand few words previously
15:46:38 mriedem np, i'm just pointing out you were both working on part of the same problem i think
15:47:24 dansmith alex_xu: why are you only bumping to 1.12 instead of to current?
15:47:31 dansmith alex_xu: because we're just going to have to bump right after this one
15:47:55 alex_xu dansmith: I have followup patch to support traits https://review.openstack.org/536085, which is 1.17
15:48:57 dansmith alex_xu: okay seems like you could just start calling at 1.17 in the first patch, but okay
15:49:02 dansmith I guess I'll rebase mine on your last change
