13:47:47 efried JulienCornuwel: Note that things involving the existing PCI passthrough subsystem are going to be difficult to get approval for, because we're trying to get rid of that whole thing.
13:47:54 sean-k-mooney stephenfin: yep
13:47:56 mgariepy so if the cell_v2 mapping was done in the upgrade, (and the create_cell returns 2, it would be right to skip the map_instances
13:48:39 JulienCornuwel efried: In favor of? Cyborg?
13:48:39 efried JulienCornuwel: That said, I think you could do what you want without really hitting that code; and in such a way that it would be transferrable to placement-based device passthrough in the future.
13:48:58 pooja_jadhav efried: After looking at the code changes done by Dan, its not taking disk_gb resource. When allocation candidates returns the response.
13:49:07 efried JulienCornuwel: Well, yes, but more generally placement.
13:49:17 mordred stephenfin, sean-k-mooney the trick is putting -c{env:UPPER_CONSTRAINTS_FILE:https://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt} into the deps list
13:49:19 mordred not the install_command
13:49:40 tssurya mgariepy: yes exactly
13:49:41 mordred like http://git.openstack.org/cgit/openstack/openstacksdk/tree/tox.ini
13:49:41 sean-k-mooney mordred: ya that is sneaky i like it
13:49:50 mgariepy thanks :)
13:50:06 mordred sean-k-mooney: it's the necessary trick for the self-constraint problem ;)
13:50:07 tssurya mgariepy: no problem
13:50:10 efried pooja_jadhav: It sounds like you should downvote the patch (it needs a rebase anyway, so you won't be the only thing holding it up) and explain what you're seeing.
13:50:33 efried pooja_jadhav: What would be even better is if you could come up with a functional test that demonstrates the behavior.
13:50:40 mordred tox installs the deps line separate from the current project - but it uses install_command for both things
13:50:52 sean-k-mooney mordred: it should also work on cygwin which the install script version did not
13:50:57 mordred so by putting constraints in deps, it winds up on the command line for the deps - but not for the install of the current project
13:51:01 mordred sean-k-mooney: yup
13:51:05 pooja_jadhav efried: But at https://github.com/openstack/nova/blob/master/nova/objects/build_request.py#L64 I can see in this db_instance the root_gb=1 value is going.
13:51:29 mordred sean-k-mooney: there are many reasons we don't like those install script wrappers - we forget to communicate all of them :)
13:52:07 pooja_jadhav efried: ok
13:52:28 openstackgerrit Takashi NATSUME proposed openstack/nova master: Transform volume.usage notification https://review.openstack.org/580345
13:53:06 JulienCornuwel efried: thanks, we'll look into that
13:53:12 sean-k-mooney mordred: well os-vif never used the install script because it broke my cygwin workflow at the time.
13:53:31 tssurya jaypipes: you appear to be the only spec core online now; whenever you get the time could you please have a look at https://review.openstack.org/#/c/581243/ ? It a very easy not fix follow-up on a merged spec
13:53:54 tssurya nit*
13:54:36 mordred sean-k-mooney: \o/
13:57:11 openstackgerrit Takashi NATSUME proposed openstack/nova master: Transform volume.usage notification https://review.openstack.org/580345
13:59:23 efried JulienCornuwel: To be a bit more specific: your notification listener would conceivably start the cleanup process, and also register the device in some kind of cache ("reserved devices"). Add logic to your get_available_resource method to look at that cache and skip reporting any devices therein.
13:59:23 efried So when we make the move to placement-based device reporting, the latter logic would go into update_provider_tree instead of get_available_resource, but everything else would stay the same.
13:59:23 efried There may still be a race in this setup, because there may be a delay before get_available_resource/update_provider_tree is run. I suppose you could get around this by making your spawn method add the device to the "reserved" list, and then have your notification listener thingy only be responsible for removing it when done.
13:59:38 openstackgerrit sean mooney proposed openstack/os-vif master: add upper_constraitns support https://review.openstack.org/583582
14:00:12 sean-k-mooney we should backport ^
14:01:48 sean-k-mooney ok going to grab lunch brb
14:02:09 openstackgerrit do3meli proposed openstack/nova master: docs: add nova host-evacuate command to evacuate documentation https://review.openstack.org/578040
14:06:12 efried sean-k-mooney: We should spell it right, though.
14:08:01 stephenfin efried: It's the main reason we keep jaypipes around, tbh
14:08:03 sean-k-mooney dambit hehe ill fix that when i get back
14:08:16 efried sean-k-mooney: I'll push the edit right quick.
14:08:39 openstackgerrit Eric Fried proposed openstack/os-vif master: add upper_constraints support https://review.openstack.org/583582
14:08:43 stephenfin spellchecker extraordinaire
14:09:02 efried sean-k-mooney: +2
14:09:18 openstackgerrit Matt Riedemann proposed openstack/os-vif master: add upper_constraints support https://review.openstack.org/583582
14:09:33 efried mriedem: wtf, yo
14:10:23 stephenfin efried: It's alright - we'd missed anyway
14:10:59 sean-k-mooney mriedem: yes you are right ill fix those
14:11:13 efried I'm still not clear that we care about upper constraints (or constraitns or constranits) for doc builds, but okay.
14:12:12 sean-k-mooney oh the pti change has merged that why i missed the others
14:12:40 jaypipes stephenfin: glad to be of service. :)
14:12:41 sean-k-mooney ok got to run to shop back in 15 min ill fix it all up then
14:13:25 stephenfin efried: Yeah, I'm on the fence myself about them, despite suggesting it in the first place
14:13:52 jaypipes tssurya: done!
14:22:17 openstackgerrit Takashi NATSUME proposed openstack/nova master: Transform libvirt.error notification https://review.openstack.org/484851
14:23:48 mriedem tssurya: the handling a down cell changes seem to be kind of all over the place, can you rebase those into a series?
14:23:54 mriedem where the api changes with the microversion come at the end?
14:24:34 mriedem i would do in this order: object change for queued_for_delete -> online data migration -> setting queued_for_delete -> handling a down cell + microversion
14:29:11 efried pooja_jadhav: Are you using DiskFilter?
14:30:00 pooja_jadhav pooja_jadhav: I have checked nova.conf, also nova-cpu.conf.. in that in enable_filters there is no any DiskFilter is added.
14:30:52 openstackgerrit Matt Riedemann proposed openstack/python-novaclient master: Microversion 2.64 - Use new format policy in server group https://review.openstack.org/578261
14:30:53 openstackgerrit Matt Riedemann proposed openstack/python-novaclient master: Add support for microversion 2.65 https://review.openstack.org/583632
14:32:25 mriedem pooja_jadhav: which release are you on?
14:32:26 openstackgerrit Merged openstack/nova-specs master: Fix nits in the handling down cell spec https://review.openstack.org/581243
14:32:39 mriedem master?
14:32:44 pooja_jadhav pooja_jadhav: Current master
14:33:07 pooja_jadhav mriedem: from cuurent master, fetched patch
14:33:23 pooja_jadhav using latest code
14:33:34 mriedem and you boot from volume and nova hypervisor-stats is showing local_gb_used=1?
14:33:42 pooja_jadhav yes
14:33:54 mriedem are you using devstack?
14:33:58 pooja_jadhav yes
14:34:23 mriedem and libvirt driver correct?
14:34:28 pooja_jadhav yes
14:34:36 mriedem does the flavor have ephemeral_gb?
14:35:23 pooja_jadhav using flavor 1 (ephemeral_gb=0, swap=0)
14:35:31 mriedem what is reserved_host_disk_mb set to in nova-cpu.conf?
14:36:20 pooja_jadhav not set any value
14:36:54 tssurya jaypipes: thanks
14:37:47 mriedem pooja_jadhav: efried: oh i see exactly why
14:38:13 efried mriedem: Do tell. I've been staring at this and slowly gleaning understanding, but am still out of my depth.
14:38:18 mriedem https://github.com/openstack/nova/blob/eb4f65a7951e921b1cd8d05713e144e72f2f254f/nova/compute/resource_tracker.py#L1455
14:38:26 mriedem the usage dict doesn't know about bfv
14:38:57 mriedem pooja_jadhav: can you check the resource allocations for that instance to make sure DISK_GB is unset or 0?
14:39:19 mriedem pooja_jadhav: https://docs.openstack.org/osc-placement/latest/cli/index.html#resource-provider-allocation-show
14:39:32 mriedem openstack resource provider allocation show <instance uuid>
14:39:35 tssurya mriedem: so the what I have it now is change for qfd -> migration and setting qfd sit on this. The patch for API changes is just a POC/WIP for nova list which I am working on to include the nova show as well.
14:39:37 mriedem DISK_GB should either not be there or 0
14:39:52 tssurya the way*
14:40:03 pooja_jadhav allocation_candidates not returning DISK_GB
14:40:06 mriedem tssurya: right i don't like how the series diverges
14:40:11 mriedem tssurya: it would be nice to line them all up
14:40:24 mriedem pooja_jadhav: you mean "openstack resource provider allocation show <instance uuid>" doesn't show DISK_GB?
14:40:29 tssurya mriedem: ack,I will rebase them the way you said
14:40:34 mriedem tssurya: thanks
14:41:01 mriedem pooja_jadhav: if that's the case, then it's working as designed in dansmith's change, and we just have a latent bug in the resource tracker for reporting disk uage for volume-backed instances
14:41:06 mriedem which isn't surprising to me
14:41:09 pooja_jadhav its showing {u'VCPU': 1, u'MEMORY_MB': 512}
14:41:13 pooja_jadhav only
