| 16:54:37 | sean-k-mooney | neutron also spanc all cells/AZs | |
| 16:54:49 | fungi | pretty sure the same can be said for the host running your vcenter api in a vmware environment | |
| 16:55:16 | sean-k-mooney | yep so it depens on your defintion of failure domains and if your inlcuding the contol plane in that | |
| 16:55:38 | sean-k-mooney | i.e. workload failrue domains vs netwrok vs storage vs contolplane | |
| 16:55:51 | sean-k-mooney | cinder backend are stroage level failure domains | |
| 16:56:39 | sean-k-mooney | of couse that is only true if you access them over seperate stoage networks | |
| 16:57:07 | fungi | or have some sort of high availability for the storage network | |
| 16:57:23 | sean-k-mooney | yep | |
| 16:57:45 | mnaser | sean-k-mooney: workload failure domains | |
| 16:57:46 | sean-k-mooney | mlag or similar with two diffent top of rack switch ectra | |
| 16:57:53 | mnaser | im thinking a scheduler hint maybe of some sorts + a filter? | |
| 16:57:57 | fungi | like cross-chassis lag | |
| 16:58:30 | sean-k-mooney | mnaser: we brifly discussed having somethign like cephs cluster map | |
| 16:58:37 | mnaser | yeah | |
| 16:59:11 | sean-k-mooney | basically building a tree of host aggrates and grouping things in a heriachy then allowing affintiy/anti affinity ectra | |
| 16:59:17 | mnaser | exactly | |
| 16:59:27 | mnaser | im thinking server group + an extra scheduler hint other than `group` to get that | |
| 16:59:39 | mnaser | but im wondering if im walking a path someone tried before and I can pick up work from or | |
| 16:59:56 | sean-k-mooney | we said it was proably too complex and out of scope of nova but that was also like 6 years ago so thngs have changes somewhat | |
| 17:00:18 | sean-k-mooney | the last time we really talks about this properly was pre/start of the pandmeic | |
| 17:00:51 | sean-k-mooney | mnaser: there is a request ot do az anti affinty this/last cycle | |
| 17:01:28 | mnaser | working in this case, it feels odd to have 1 az per rack | |
| 17:01:28 | sean-k-mooney | in generally i woul dnot be agsint this in principal. it just would not be high on my list of thing to do next | |
| 17:01:50 | mnaser | like that feels like its brute forcing the az feature if you're on rack level | |
| 17:01:52 | sean-k-mooney | az's are just named aggreates | |
| 17:02:37 | mnaser | yeah but I feel like in the perspective of a consumer of the cloud they might be like "oh isn't this like a azure/aws/etc az?" | |
| 17:03:08 | sean-k-mooney | and the answer to hell no | |
| 17:03:20 | sean-k-mooney | but i get that persective | |
| 17:03:42 | sean-k-mooney | so what i would say is we could and might want to make nova eand other services better able to supprot that usecase | |
| 17:03:57 | mnaser | cause like maybe it would be nice to be like.. this is an az .. but also you can have different fault domains | |
| 17:04:06 | sean-k-mooney | but i think we would need some feature in placment to do it effeictly | |
| 17:04:24 | sean-k-mooney | doing it in a filter or weigher would likely be slow an maybe buggy | |
| 17:05:40 | sean-k-mooney | im not saying we could not do it in nova alone but we would need to becareful with how we design it | |
| 17:05:44 | fungi | in retrospect it was probably a mistake to call them availability zones when the implementation wasn't equivalent to aws's az concept, because we've had to fight that confusion ever since, but it'd be hard to change now (i still refer to projects as tenants, after all) | |
| 17:06:35 | sean-k-mooney | nova still has instance_type and flavor depending on what your looking at | |
| 17:06:44 | fungi | indeed | |
| 17:07:20 | sean-k-mooney | so i think an aggerate groups feature is definlty doable and i like cpehs model | |
| 17:07:38 | fungi | we just missed rounding out the suite of renames with "color" and "texture" and maybe "odor" | |
| 17:07:48 | sean-k-mooney | i just feel like crambing that into the existing filters/weither might be sub optimal | |
| 17:09:04 | sean-k-mooney | im sure if we renamed flavors to Terroir it would confuse noone | |
| 17:23:45 | mnaser | sean-k-mooney: I think the path of least resistance is a filter that checks if there is a server group assigned, and a scheduler hint called `different_failure_domain` .. and that goes over host aggregates which have a `failure_domain` attribute and ensures that the hosts in the server group dont end up in that same host aggregate | |
| 17:24:51 | sean-k-mooney | mnaser: i really dont like schduler hits | |
| 17:24:58 | sean-k-mooney | btu thats an option | |
| 17:25:22 | mnaser | sean-k-mooney: could also use `rules` for server groups to have `different_failure_domain` too | |
| 17:25:29 | opendevreview | Dan Smith proposed openstack/nova master: Add iso file format inspector https://review.opendev.org/c/openstack/nova/+/923533 | |
| 17:25:29 | opendevreview | Dan Smith proposed openstack/nova master: Reproduce iso regression with deep format inspection https://review.opendev.org/c/openstack/nova/+/923507 | |
| 17:25:31 | mnaser | but that would mean an api change | |
| 17:25:34 | sean-k-mooney | server group/instance wawere filteres are some of the most ram/compute intesitve you can create | |
| 17:27:29 | mnaser | yeah | |
| 17:27:37 | mnaser | that is for sure going to be a busy one | |
| 17:28:17 | mnaser | im not sure if there's another approach | |
| 17:43:44 | fungi | 923287 failed out on nova-next and nova-multi-cell: https://zuul.opendev.org/t/openstack/buildset/0a50e0745e3e4759bf743b39208ed1dc | |
| 17:44:07 | fungi | i've reenqueued it and repromoted | |
| 18:02:10 | opendevreview | Dan Smith proposed openstack/nova master: Add iso file format inspector https://review.opendev.org/c/openstack/nova/+/923533 | |
| 18:27:44 | dansmith | fungi: confirmed at least one of those was a guest kernel panic so obviously unrelated | |
| 18:28:03 | fungi | exciting! | |
| 18:28:25 | fungi | and good to know, thanks for taking a look | |
| 18:28:26 | dansmith | not really, we see guest kernel panics way too often :( | |
| 18:28:42 | fungi | yeah, my excitement was understated sarcasm really, sorry | |
| 18:28:49 | dansmith | heh, okay | |
| 18:29:48 | fungi | i've about worn out all other tools at my disposal, so sarcasm is what's left at this point | |
| 18:30:27 | dansmith | yeah, you don't have to apologize to me for that.. I'm beyond exhausted.. I dunno what's after that before death, maybe "acceptance" ? | |

| 20:11:30 | fungi | 923290 hit a package install error, and that knocked out 923291 as a child commit. i'll get them both back into play but they're the only changes left from the ossa | |
| 20:13:42 | fungi | waiting to promote them to the front since there's a stack of 5 succeeding changes that are due to merge in the next 10 minutes | |
| 20:14:08 | fungi | but once those land i'll shuffle them up | |
| 20:27:34 | fungi | and done | |

| 22:32:05 | fungi | yay!!! | |
| 22:44:43 | dansmith | fungi: thanks for all your work, I didn't appreciate how much that would involve you and your clicky finger | |
| 22:45:14 | fungi | no worries, it was thoroughly calloused already | |
| 22:46:02 | fungi | (no actual clicking was done, unless you count the clickity-clack of my mechanical keyboard) | |
| 22:46:29 | fungi | like all real software, zuul has a proper cli | |
