#openstack-nova - 2018-05-02
23:28:27 melwitt okay. well, I'm just saying verifying the traits in placement seems like the only correct thing to do
23:30:38 arvindn05 ideally yes, but a rebuild request never gets to placement api with any of the options described in the thread i think
23:31:34 arvindn05 is there an different alternative where verifying the traits can happen in placement code in case of rebuild?
23:32:49 melwitt what? some of the options involve calling placement
23:35:01 arvindn05 sorry if its unclear...i meant if there is way to utilize the matching logic of placement instead of trying to duplicate that in the conductor/schedulers
23:39:15 melwitt if there's a way to ask placement "do these providers have these traits?" then that's what we need right? we need to ask if the providers hosting our current allocations have the traits requested in the image
23:40:11 melwitt if we could ask it that way, placement would do the matching. but I don't have deep knowledge the placement APIs
23:41:10 melwitt that is, I don't know if there's an available API like that
23:41:24 arvindn05 As i understand it its not just "do these providers have these traits?"...its also "do we have allocations from these providers for those traits?"
23:42:07 arvindn05 since we cannot do allocations during rebuild...we need to make sure our existing allocations satisfy all the trait requirements
23:42:15 melwitt it is, and that's what I tried to say. we have to 1) know our allocations 2) know what providers are hosting our allocations 3) know what traits the providers in 2) have
23:44:22 melwitt so I guess it would be 1) query for own allocations by consumer == our instance 2) use the providers returned by that to ask 2) do these providers have these traits. again, I'm making up the second query, I don't know if one like that exists
23:44:54 melwitt maybe I made up the first one too, but you get the idea
23:45:45 arvindn05 yea...that was what efried had...
23:47:36 arvindn05 2. we need to need to account for handling preferred traits or granular resource traits if we decide to implement them for images at some point...
23:47:36 arvindn05 1.the rebuild may or may not succeed, depending on how well the original allocations match up with the new requirements.
23:47:36 arvindn05 the only 2 cons for this approach
23:47:39 arvindn05 see http://lists.openstack.org/pipermail/openstack-dev/2018-May/130087.html
23:48:12 arvindn05 to see why 1 may occur....
23:51:35 melwitt are traits the same as properties? do they replace properties or?
23:51:42 melwitt *image properties
23:53:13 arvindn05 they are an addition to image properties...
23:53:34 arvindn05 maybe long term they can start to replace some of the image properties....
23:53:58 melwitt okay. was just thinking about whether 1. would be a regression on how it behaves today. you can rebuild with a new image with new image properties if they pass scheduler filtering
23:54:41 melwitt if image property == image trait then if you reject any rebuild with new traits, then that's a step backward from what's possible today
23:56:23 arvindn05 nope traits are independent of image properties...they use the same key:value and are expressed as such in the image properties...but not the same
#openstack-nova - 2018-05-03
00:01:23 arvindn05 i think either of the 2 options we boiled down to work for me....i put this in open dicussion for tommorow's meeting...hopefully we get concensus then :)

08:23:49 gibi bauzas: could you look at a small spec template update that already has +2 from mriedem? https://review.openstack.org/#/c/562265/
08:24:11 bauzas sure
08:24:50 gibi bauzas: thanks
08:25:41 bauzas done
08:25:47 bauzas with a comment but +Wd
08:27:37 gibi bauzas: I can quickfix your nit then you can fastapprove it
08:28:23 bauzas gibi: nah, no worries
08:28:29 bauzas I understand what's an API entity
08:28:34 bauzas no need for a followup
08:28:41 bauzas and I'm not a API SIG expert ;)
08:28:54 bauzas but I use a vocabulary
08:29:05 bauzas REST verbs : GET, PUT, etc.
08:29:12 gibi bauzas: OK then let's merge it as is :)
08:29:15 bauzas REST resource : /servers, etc.
08:29:46 gibi bauzas: I think your vocabulary is the correct one
08:29:55 bauzas actions are not RESTful
08:30:12 bauzas but let's call it a subcollection
08:30:28 kashyap Those who can +2 backports, can you put this through please: https://review.openstack.org/#/c/565668/
08:30:33 kashyap (It already has a +2.)
08:31:11 bauzas kashyap: just did
08:31:25 kashyap bauzas: Fantastic. I've got two more, mind looking there too?
08:31:39 bauzas kashyap: see matt's comment
08:32:03 bauzas kashyap: https://review.openstack.org/#/c/565670/1
08:32:30 openstackgerrit Merged openstack/nova-specs master: Suggest when to propose notification changes https://review.openstack.org/562265
08:32:44 kashyap bauzas: Actually, that's what I did
08:32:48 kashyap But let me double-check
08:33:07 gibi bauzas: subcollection sound weird. as PUT and GET is called verb, the 'action' term for our unRESTful actions makes more sense to me
08:36:42 kashyap bauzas++
08:38:24 bauzas gibi: fair enoguh
08:38:34 bauzas gibi: let's call it an API action
08:38:47 gibi bauzas: action on an API resource :)
08:38:50 bauzas gibi: but not a REST action, which is an oxymore
08:39:18 bauzas anyway, we're furiously ratholing
08:39:51 gibi a good morning rathole to get us up to speed
