| 15:09:40 | bauzas | gibi: any reason why you don't provide the VGPU inventory first ? | |
| 15:19:41 | openstackgerrit | Kashyap Chamarthy proposed openstack/nova master: libvirt: Drop MIN_LIBVIRT_PARALLELS_SET_ADMIN_PASSWD https://review.openstack.org/632514 | |
| 15:39:14 | gibi | bauzas: sorry I was dragged away from the keyboard | |
| 15:39:24 | bauzas | gibi: heh, we all are | |
| 15:39:38 | bauzas | or, rather, always dragged from upstream | |
| 15:42:56 | gibi | bauzas: if https://review.openstack.org/#/c/631559/5/nova/tests/functional/libvirt/test_reshape.py@130 fails then it means that the reshape does not moved the VGPU resource away from the compute RP to the GPU RP | |
| 15:43:15 | gibi | bauzas: https://review.openstack.org/#/c/631559/5/nova/tests/functional/libvirt/test_reshape.py@123 should trigger the reshape | |
| 15:43:41 | bauzas | I'll dig into pdbing it | |
| 15:43:58 | bauzas | in the meantime, lemme mark my series as -2 | |
| 15:54:04 | openstackgerrit | Alexandra Settle proposed openstack/nova master: Adding cross refs for config options in scheduler filter guide https://review.openstack.org/636635 | |
| 15:59:07 | gibi | bauzas: http://logs.openstack.org/59/631559/5/check/nova-tox-functional/100cfb6/job-output.txt.gz#_2019-02-13_11_19_37_215302 here is when the compute is restarted and should do the reshape | |
| 16:02:00 | openstackgerrit | Jack Ding proposed openstack/nova master: Flavor extra spec and image properties validation https://review.openstack.org/620706 | |
| 16:24:19 | melwitt | o/ | |
| 16:50:45 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Use math.gcd starting with python 3.5 https://review.openstack.org/636669 | |
| 16:51:40 | melwitt | mriedem: there's a patch proposed to add basic info about projects to the openstack-map, if you're interested in reviewing the nova info https://review.openstack.org/636604 | |
| 17:01:46 | openstackgerrit | Vlad Gusev proposed openstack/nova stable/queens: Handle unicode characters in migration params https://review.openstack.org/636678 | |
| 17:09:09 | mriedem | melwitt: commented | |
| 17:09:13 | mriedem | dansmith: replied on https://review.openstack.org/#/c/469675/ | |
| 17:09:34 | mriedem | dansmith: for sanity, i think we likely just want to stop using check_availability_zone in both the api and compute | |
| 17:09:39 | mriedem | and write an api-specific version of that | |
| 17:10:26 | mriedem | from the api, gather all the precreated volumes and their azs, | |
| 17:10:30 | mriedem | if any are different, it's an error | |
| 17:10:38 | mriedem | if any are different from the requested server az, it's an error | |
| 17:10:58 | mriedem | if the server is created without a specific az, and the volumes all have the same az, then put that on the request spec | |
| 17:12:32 | dansmith | mriedem: yeah, collect the data and make the call in the compute api | |
| 17:12:55 | dansmith | mriedem: like I said, if the "user requested an az and it doesn't match the volume" case still needs to be handled deep for cleanup reasons, then okay, | |
| 17:13:34 | dansmith | but (a) default_az means something totally different to me when reading the compute/api code and (b) I don't expect either of these mismatch checks to happen so deep down in that file | |
| 17:14:03 | dansmith | so if you don't want to refactor this at all, I'd at least ask that you change the name of that parameter with commentage up in compute/api aboutit | |
| 17:15:28 | mriedem | "the "user requested an az and it doesn't match the volume" case" is what would be in nova-compute after a volume is created | |
| 17:15:33 | mriedem | so yeah i think that remains | |
| 17:16:01 | dansmith | wait | |
| 17:16:23 | dansmith | oh right, yeah | |
| 17:17:00 | mriedem | which reminds me of https://bugs.launchpad.net/nova/+bug/1497253 | |
| 17:17:02 | openstack | Launchpad bug 1497253 in OpenStack Compute (nova) "different availability zone for nova and cinder when AZ is not explicitly given" [Low,Fix released] - Assigned to Dan Smith (danms) | |
| 17:19:21 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Remove get_config_vhostuser https://review.openstack.org/565471 | |
| 17:19:32 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Validate bandwidth configuration for other VIF types https://review.openstack.org/636383 | |
| 17:19:44 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Further de-dupe os-vif VIF tests https://review.openstack.org/636384 | |
| 17:21:12 | stephenfin | gibi: Trivial doc fix here, if you fancy taking a look https://review.openstack.org/#/c/636635/ | |
| 17:26:09 | mriedem | dansmith: right so i'm thinking leaving the nova-compute behavior the same, and probably move that check_availability_zone method to nova.virt.block_device where it's actually used | |
| 17:26:16 | mriedem | and writing something new in the API | |
| 17:26:22 | dansmith | makes sense | |
| 17:26:25 | mriedem | that has the user-requested (or not) AZ context | |
| 17:26:59 | mriedem | having said that, it's pot-pie-o-clock and i've got a physical this afternoon (first in 10+ years) so my attendance will be spotty | |
| 17:27:14 | mriedem | oh and (don't tell laura) i have to get a valentine | |
| 17:27:44 | dansmith | mriedem: you might be approaching that age where the doctor starts wanting to take your relationship to the next level | |
| 17:27:58 | mriedem | i'm holding out for my 40s | |
| 17:28:03 | dansmith | heh | |
| 17:34:32 | tzumainn | hi! quick question about the expected behavior with nova and ironic; I have four baremetal nodes, and I've created one server that runs on one of the nodes, but if I run "nova hypervisor-servers" against each node, that server shows up for every single node | |
| 17:40:36 | melwitt | tzumainn: are you running one nova-compute service for all four baremetal nodes? if so, I think that might be why it shows up for every node | |
| 17:41:08 | melwitt | I'd have to look into the code to find how the hostname => server lookup is done to confirm | |
| 17:41:30 | melwitt | jroll ^ | |
| 17:41:43 | tzumainn | melwitt, ah, yeah, I am | |
| 17:42:44 | jroll | I'm not sure what "nova hypervisor-servers" is | |
| 17:42:56 | jroll | but yeah, probably only goes by compute service hostname, not node name | |
| 17:43:26 | melwitt | it's a command to get a list of servers given a hostname | |
| 17:46:29 | bauzas | dansmith: stop me 1 sec, do we now need to set the host mappings when deploying with devstack ? | |
| 17:46:56 | dansmith | bauzas: devstack should do that for you | |
| 17:47:06 | jroll | melwitt: ah, sounds like a bug in that API response | |
| 17:47:26 | bauzas | dansmith: that was my assumption but I got a Host 'XXX' is not mapped to any cell | |
| 17:47:54 | dansmith | bauzas: on a vanilla devstack setup? shouldn't happen afaik | |
| 17:48:30 | bauzas | technically, a reinstalled devstack but with a ./clean.sh and a reclone=true | |
| 17:48:38 | melwitt | jroll: I get what you mean now, might be returning host instead of node | |
| 17:48:41 | bauzas | weirdo | |
| 17:49:02 | jroll | melwitt: yeah | |
| 17:49:34 | melwitt | thanks | |
| 17:50:39 | bauzas | dansmith: nevermind, looks like a rabbit issue | |
| 17:50:50 | mriedem | bauzas: i'm pretty sure clean.sh isn't maintained | |
| 17:50:54 | mriedem | i never use it | |
| 17:51:13 | bauzas | mriedem: okay, how do we clean the data then ? | |
| 17:51:16 | bauzas | rm -rf ? | |
| 17:51:19 | melwitt | tzumainn: ok, there might be a bug there. I can do some digging later to confirm and check if we have any open bugs or patches about it already | |
| 17:51:46 | mriedem | bauzas: if i need a clean slate i create a new devstack vm | |
| 17:51:54 | bauzas | lucky you :p | |
| 17:52:09 | mriedem | lemme guess, you're running devstack on baremetal with gpus | |
| 17:52:12 | bauzas | here I'm talking of some internal server that I got by accident | |
| 17:52:37 | bauzas | mriedem: yeah, I want to test the reshape series on real hardware | |
| 17:53:11 | bauzas | -where we have RHEL7.5... - | |
| 17:53:22 | bauzas | but anyway, will continue to look | |
| 17:53:35 | tzumainn | melwitt, thanks! I didn't see an existing bug, but looking at https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/hypervisors.py#L167-L168 maybe what I'm seeing is intended behavior, and it's matching based on the hypervisor host_ip (which is the same for all four baremetal nodes)? | |
| 17:55:09 | mriedem | tzumainn: it's a fuzzy search on hypervisor hostname https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/api.py#L680 | |
| 17:55:42 | mriedem | for ironic nodes that should actually be a uuid | |
| 17:55:47 | tzumainn | mriedem, yep, that's what I'm using | |
| 17:56:47 | mriedem | and the API code is taking that compute node record and getting all instances on that compute_nodes.host | |
| 17:56:50 | mriedem | which is the same for all of your nodes | |
| 17:57:05 | mriedem | compute_nodes.host == nova-compute service hostname == instances.host | |
| 17:57:22 | mriedem | so it's working as expected, i.e. that API is not ironic-aware | |
| 17:57:25 | mriedem | nor is most of the compute API | |
| 17:57:27 | mriedem | hence MOGAN | |
| 17:57:30 | melwitt | tzumainn: yeah, internally in nova we have hypervisor "hostname" which is associated with the nova-compute service and we have "nodename" which is the ironic nodename. if you're not using ironic hostname == nodename. else, it will be different and to get the right answer (better answer?) for ironic, we'd need to do a lookup based on nodename, not "hostname" | |

| 17:59:54 | tzumainn | mriedem, melwitt gotcha - okay, thanks! | |
| 18:00:16 | mriedem | tzumainn: without an api change the best we can do right now is document the wrinkle in the api reference | |
| 18:01:11 | tzumainn | mriedem, would an API change be possible in the longer-term, or would you consider this a tragic wrinkle in how nova/ironic interact? | |
| 18:01:42 | mriedem | tzumainn: i think it could be a possible change on a new microversion - if the resulting compute node we found is of type ironic, we have to lookup instances by nodename, not host | |
