| 13:14:15 | mgariepy | https://paste.openstack.org/show/bP2oY2IOe4lNvj6wGB8w/ | |
| 13:14:51 | mgariepy | what is resolving the alias ? is it dont by the scheduler directly ? | |
| 13:15:27 | sean-k-mooney | that depends on the request | |
| 13:15:47 | mgariepy | my flavor has alias stuff in in. | |
| 13:15:49 | sean-k-mooney | but no i think its doen in the compute or the api | |
| 13:16:53 | sean-k-mooney | https://docs.openstack.org/nova/latest/admin/pci-passthrough.html#configure-nova-api | |
| 13:17:07 | sean-k-mooney | so for ne vm request this is usd by the nova-api not the scheduler | |
| 13:17:30 | sean-k-mooney | and for rezize its used form teh compute | |
| 13:17:45 | sean-k-mooney | so if you are udataing this you need to restart the nova-api not the scheduler | |
| 13:18:26 | sean-k-mooney | the scheudle reciveds a fully popultated RequestSepc object which has the pci resuets embeeded in it | |
| 13:19:38 | mgariepy | but me resquest doesn't receive the device_type :/ | |
| 13:23:12 | sean-k-mooney | did you restart the nova-api processes after updating hte alias | |
| 13:24:02 | mgariepy | i did restart the nova slice. let me try juste putting the same config accross all the cluster to see if it changes something. | |
| 13:32:19 | mgariepy | what driver shoud be loaded fo the pci dev ? | |
| 13:32:56 | mgariepy | pci-stub or vfio-pci ? | |
| 13:32:58 | sean-k-mooney | the driver should not matter to the schduler | |
| 13:33:13 | sean-k-mooney | that woudl only matter on the compute node but yes either of those shoudl work | |
| 13:33:18 | mgariepy | ok | |
| 13:33:36 | sean-k-mooney | the important part is that the framebuffer is not initallised by xorg/wayland as that woudl prevent the passthough | |
| 13:33:53 | mgariepy | ha ok. | |
| 13:34:13 | sean-k-mooney | vfio-pci is what kvm/qemu will use when its being passthough through | |
| 13:34:26 | sean-k-mooney | so prebinding to that is generally not a bad idea but often not required | |
| 13:34:46 | mgariepy | i did some stuff with passthrough with el-cheapo gamer gpus. but with older openstack release. | |
| 13:35:50 | sean-k-mooney | thre is nothing really that has changed that would impact this | |
| 13:36:06 | sean-k-mooney | the alias and whitelist/device list syntax is the same | |
| 13:36:22 | sean-k-mooney | and your reporting that its fialing in the pci filter os its not related to the placment part | |
| 13:36:31 | sean-k-mooney | since it passes that to get to the point where its failing | |
| 13:37:09 | mgariepy | yeah i'll retest in like 30 minutes.. meeting time ;) | |
| 15:04:23 | mgariepy | sean-k-mooney, it works now Thanks a log for your help. | |
| 15:04:47 | mgariepy | with the type-PF and all my server with the same config it's almost magical :D | |
| 15:21:51 | sean-k-mooney | awsome | |
| 15:21:52 | opendevreview | Sylvain Bauza proposed openstack/placement master: Update 2023.2 reqs to support os-traits 3.0.0 as min version https://review.opendev.org/c/openstack/placement/+/895186 | |
| 15:22:21 | sean-k-mooney | the reqeust was proably being accpeted by a not restarted instace | |
| 15:22:29 | mgariepy | yeah | |
| 15:23:01 | bauzas | dansmith: sean-k-mooney: forgot to propose the requirements update for the new traits : https://review.opendev.org/c/openstack/placement/+/895186 | |
| 15:23:05 | mgariepy | any tips on debugging that sort of stuff when multiple instance of every service are running ? | |
| 15:23:08 | bauzas | we need it before RC1 | |
| 15:23:39 | dansmith | bauzas: aren't we past requirements freeze? | |
| 15:23:46 | dansmith | is that in u-c already? | |
| 15:24:41 | bauzas | dansmith: os-traits was delivered in March | |
| 15:24:46 | bauzas | and u-c already has it | |
| 15:24:52 | dansmith | okay | |
| 15:24:56 | bauzas | https://opendev.org/openstack/requirements/raw/branch/master/upper-constraints.txt | |
| 15:25:13 | dansmith | ack, cool | |
| 15:25:20 | bauzas | so we just need to say 'look, for Bobcat, we need to accept only 3.0 since we use a trait in it" | |
| 15:25:40 | bauzas | I haven't checked tho whether we really use this trait in Placement but I'm assuming it | |
| 15:26:11 | dansmith | bauzas: wait you're not sure if we need the new traits? :) | |
| 15:26:58 | dansmith | we just bumped for this a few weeks ago: https://review.opendev.org/c/openstack/nova/+/873221 | |
| 15:38:38 | opendevreview | Gorka Eguileor proposed openstack/nova master: Fix load_validators https://review.opendev.org/c/openstack/nova/+/895189 | |
| 15:39:12 | opendevreview | Gorka Eguileor proposed openstack/nova master: Fix debug options https://review.opendev.org/c/openstack/nova/+/895190 | |
| 15:39:12 | opendevreview | Gorka Eguileor proposed openstack/nova master: Logs cinderclient requests when debugging https://review.opendev.org/c/openstack/nova/+/895191 | |
| 15:39:40 | opendevreview | Gorka Eguileor proposed openstack/nova master: Fix guard for NVMeOF volumes https://review.opendev.org/c/openstack/nova/+/895192 | |
| 15:53:20 | bauzas | dansmith: so, I made a few researches, my bad, just followed blindly a pattern from Antelope when I did https://review.opendev.org/c/openstack/placement/+/874080 | |
| 15:54:09 | bauzas | so, https://review.opendev.org/c/openstack/nova/+/873221 is using traits-2.10 https://review.opendev.org/c/openstack/releases/+/873106 which is already supported as minimum | |
| 16:10:55 | bauzas | dansmith: so, I think I'll abandon https://review.opendev.org/c/openstack/placement/+/895186 | |
| 16:11:08 | dansmith | bauzas: okay | |
| 16:12:28 | bauzas | I'm actually lost, we created 3.0 in order to no longer support py2.6 and py2.7 | |
| 16:12:31 | sean-k-mooney | bauzas: so https://review.opendev.org/c/openstack/nova/+/831194/37/nova/share/manila.py#43 is returning the connection to via the sdk to talke to manilla | |
| 16:12:59 | bauzas | sean-k-mooney: sec, trying to see whether we need https://review.opendev.org/c/openstack/releases/+/894698 | |
| 16:13:06 | sean-k-mooney | its fine | |
| 16:13:20 | sean-k-mooney | focus on that i was just wonderign where the error was | |
| 16:13:54 | bauzas | sorry I meant https://review.opendev.org/c/openstack/placement/+/895186 | |
| 16:14:26 | bauzas | we'll add a new trait which isn't used yet by Nova | |
| 16:14:44 | bauzas | but we'll also make py3.6 and py3.7 unsupported | |
| 16:20:03 | bauzas | dansmith: sean-k-mooney: okay, I think I sorted it, we eventually need https://review.opendev.org/c/openstack/placement/+/895186 not because of the new trait, but because we want to unsupport 3.6 and 3.7 | |
| 16:20:09 | bauzas | in Bobcat | |
| 16:20:14 | dansmith | okay | |
| 16:20:38 | sean-k-mooney | ok so i should +2w that then right | |
| 16:20:43 | sean-k-mooney | the min version bump to 3.0.0 | |
| 16:24:35 | bauzas | sean-k-mooney: sorry, yeah | |
| 16:24:47 | bauzas | thanks | |
| 16:39:31 | sean-k-mooney | mgariepy: the only real tip is to use the request-id to corralate the requets across diffent services when looking at the logs | |
| 16:40:03 | sean-k-mooney | that and try and use automation like kolla-ansible to ensure you have the same config on all relevent nodes rather then doing manual changes | |
| 16:40:27 | sean-k-mooney | but no not really other then that | |
| 17:03:15 | mgariepy | sean-k-mooney, i'm using openstack-ansible | |
| 17:03:56 | mgariepy | when doing changes that i'm not quite sure i do it manually instead of doing it via osa. | |

| 07:44:11 | sahid | o/ | |
| 07:44:43 | sahid | still with my fighting regarding aggregate and az. There is one thing I wanted to mention | |
| 07:45:52 | sahid | I have noticed the behavior betzeen placement aggregate multitenance isloation in placement and the filter aggregate multitenancy isolation of the sheduler | |
| 07:46:36 | sahid | the filter scheduler accepts host which does not belong to an aggregate with filter_tenant_id | |
| 07:50:08 | sahid | so tenant_id can be scheduled to hosts that do not belong to an aggregate with filter_tenant_id=tenant_id, where in placement tenant_id can *only* be scheduled to hosts that belong to aggregate with filter_tenant_id=tenant_id | |
| 07:50:19 | sahid | i'm not sure I'm clear :-) | |
| 08:44:13 | bauzas | sahid: you're perfectly clear :) | |
| 08:44:26 | bauzas | placement prefilter behaves different from the scheduler filter | |
| 08:55:01 | sahid | bauzas: thanks :-) the question that i have also is that, is there any plan to move all the filters in placement and so remove the scheduler? My point is that, the current AggregateMultitenancyIsolation is limited regarding the number of project_id we can set as part of filter_tenant_id (limited by the db field for value of an aggregate key I guess). Does that make sense to provide a patch to remove | |
| 08:55:07 | sahid | that limitation by adding a logic like we have in placement? | |
| 08:55:10 | sahid | or we just don't want to involve on scheduler fitler anymore? | |
| 08:55:37 | bauzas | sahid: we eventually came to the conclusion that this was impossible and unwantable to move all the filters into placement prefilters | |
| 08:56:11 | bauzas | but everytime we have resources in placement, we shall have prefilters yeah | |
| 08:57:10 | bauzas | back to your question, I'd say that there is no clear stance about the AggregateMultitenancyIsolation filter | |
| 08:57:16 | bauzas | it behaves a bit differently | |
| 08:57:26 | bauzas | so we could keep it and patch it if required | |
| 08:57:36 | bauzas | the limitation you mention is indeed a DB problem | |
| 08:58:18 | bauzas | but I assume placement would also have this limitation (at least it's limited by the length of the URL and the size of the response :) ) | |
| 08:59:05 | sahid | thanks a lot for all those points | |
| 08:59:58 | sahid | for placement filter_tenant_id is a prefix for the key, it searches to match all keys in the aggregate that start with filter_tenant_id | |
| 09:00:17 | sahid | which well remove the limitation :-) | |
| 12:40:28 | bauzas | ralonsoh: looks like some neutron revert is also needed here : https://9646a7fb82b47fbe6288-a22e2178400a1d74c0dfc0d0570ba9cf.ssl.cf2.rackcdn.com/894945/1/check/nova-grenade-multinode/e307f26/testr_results.html | |
| 12:42:35 | zigo | Is there a PBR equivalent to pyproject.toml's : | |
