19:20:33 sean-k-mooney josephillips: that is not disto specfic
19:21:09 sean-k-mooney although the charms may or may not configure the plament aggreats for you i have not really looked at how they work in a few years
19:21:15 openstackgerrit Elod Illes proposed openstack/nova stable/train: [train-only] Remove pycodestyle from test requirements https://review.opendev.org/729004
19:22:05 sean-k-mooney josephillips: i would expect that you can either configure it in the compute node cofnig per host using the juju chram for nova or you have to do it manually via placement after the fact
19:22:40 josephillips sean-k-mooney: i lost in your explanation of the AggregateTypeAffinityFilter limitations
19:23:00 josephillips if i have the flavor m1 for the m1 servers they dont have any host aggregate
19:23:09 josephillips m2 flavors only for m2 servers with host aggregate
19:23:20 josephillips m2 flavors can land on m1 servers?
19:23:28 sean-k-mooney yes
19:23:39 josephillips under what circustances?
19:23:45 sean-k-mooney but m1 instance cannot land on m2 servers
19:24:00 sean-k-mooney josephillips: it depend on the weighers
19:24:29 josephillips so the correct way is be specific with nodes m1 and nodes m2
19:24:37 sean-k-mooney if the weigher consider the m1 server to be a better choice because they have more free ram,disk ectra then it will select them
19:24:46 sean-k-mooney josephillips: yes
19:25:25 sean-k-mooney if you want to force it to only land on the specifc set you need to create a general host aggreate with all the m1 host and an m2 host aggreate with just the m2 hosts
19:25:46 sean-k-mooney then in the genral host aggreate list all the flavor excpet the m2 flavor and in the m2 host aggreate only list the m2 flavor
19:26:36 sean-k-mooney josephillips: tl;dr the AggregateTypeAffinityFilter prevent flavor that are not in the list form landing in the aggreate
19:27:02 sean-k-mooney josephillips: it does not force flavor to land on an aggreate
19:28:26 sean-k-mooney three is one thing you could do since your on train
19:28:34 sean-k-mooney to make it slightly simpler.
19:29:04 sean-k-mooney you could create only the aggreate for the special m2 hosts and use teh AggregateTypeAffinityFilter as you are doing now
19:29:48 sean-k-mooney but you caould also add a custom trait to all those hosts in plamcnet and then add trait:CUSTOM_MY_TRAIT=required
19:30:03 sean-k-mooney to the flavor
19:30:26 sean-k-mooney the custom required trait will force plamcent to only slect the hosts where you applied trait
19:30:43 sean-k-mooney and the filter will prevent instnace that dont have the correct flavor form landing there
19:30:56 sean-k-mooney if you put those two things togeter it will do what you want
19:31:25 sean-k-mooney your m2 instance will only land on the m2 host and the m1 instance cant land on the m2 hosts
19:32:03 sean-k-mooney josephillips: im about to leave for the night but one question before i do. your are not trying to use this for tenant isolation are you?
19:33:43 sean-k-mooney josephillips: this feature https://docs.openstack.org/nova/latest/reference/isolate-aggregates.html might be of use to you
19:35:07 sean-k-mooney josephillips: as might https://docs.openstack.org/nova/latest/admin/aggregates.html#tenant-isolation-with-placement if you are interested in the teant isolation case
19:35:42 sean-k-mooney the isolate aggreates feature is what was descibing as the hybrid approch
19:40:09 sean-k-mooney the isolate-aggregates featuer which is new in train might be the only thing you require to achive your goal. it was intended for more or less the same usecase but im not sure as you did not clearly state what you were trying to achive.
19:41:08 josephillips no
19:41:11 josephillips sean-k-mooney: im just looking use a second family of procesors and
19:41:23 josephillips dedicate some nodes for SaaS applicatios
19:42:06 sean-k-mooney https://docs.openstack.org/nova/latest/reference/isolate-aggregates.html shoudl allow you to do that
19:42:54 sean-k-mooney openstack --os-placement-api-version 1.6 trait create CUSTOM_SAS_HOSTS
19:43:22 sean-k-mooney then you can add CUSTOM_SAS_HOSTS to each host that you want to use
19:43:42 sean-k-mooney for sas applcaipton
19:43:54 josephillips and i add these meta to the flavor
19:43:55 josephillips ?
19:44:02 josephillips CUSTOM_SAS_HOSTS
19:44:26 sean-k-mooney in the flavor you set trait:CUSTOM_SAS_HOSTS=required
19:44:32 sean-k-mooney and you set the same in a host aggreate
19:44:59 sean-k-mooney openstack --os-compute-api-version 2.53 aggregate set --property trait:CUSTOM_SAS_HOSTS=required MY_SAS_HOST_AGGREATE
19:45:09 josephillips so im still have to use host aggregate
19:45:10 josephillips ?
19:45:17 sean-k-mooney yes
19:45:26 josephillips without any filter?
19:45:32 sean-k-mooney yes
19:45:43 josephillips mhmmm. i will try this
19:45:59 sean-k-mooney so you enable the featrure in the scudler config scheduler.enable_isolated_aggregate_filtering=true
19:46:44 josephillips just for ask and sorry for ask this but what is exactly the difference doing the filtering by nova or by placement
19:47:07 sean-k-mooney placemnt is faster and the way we want to do this going forward
19:47:28 sean-k-mooney plamcent returns a subset of host which is then processed by the filters in nova
19:47:39 sean-k-mooney so if you do it in placment the filter have much less work to do
19:47:54 josephillips ok
19:48:08 josephillips one las question what is the recommendation
19:48:19 josephillips if i will add more nodes with m2 processors
19:48:23 josephillips for general use
19:48:33 josephillips i create another trait:M2_hosts
19:48:36 josephillips and the flavor
19:48:59 josephillips for these hosts and thats it? is the correct way when you adding new servers with different specs
19:49:05 sean-k-mooney if you take the https://docs.openstack.org/nova/latest/reference/isolate-aggregates.html apporch you just dont add teh custom trait to the m2 hosts you want for general use
19:51:17 sean-k-mooney josephillips: what i would suggest it take a few minutes to read teh spec https://specs.openstack.org/openstack/nova-specs/specs/train/implemented/placement-req-filter-forbidden-aggregates.html and understand teh feature an see if your probelme is adress by it. i think it is and then feel free to come back and ask some quetions about it after you play awound with it a bit in a day or two
19:52:10 josephillips thank you so much
19:52:18 sean-k-mooney there are a few way with verinly level of complexity to achive what you want and different level of operation overhead so really you need to make a value judgement on what is best for you
19:52:53 josephillips you
19:53:09 josephillips you have been very helpful sean-k-mooney at least now i have ideas of how to solve it
19:53:29 sean-k-mooney glad i could help o/
