| 17:06:57 | ratailor | gibi, I already submitted changes for sdk and client here https://review.opendev.org/q/topic:%22bp/image-props-in-server-show%22 but the tests are failing, because not sure how to add 'image_properties' attr to class Server in openstacksdk with 2.98 version specific. | |
| 17:07:25 | ratailor | gibi, could you please check and provide your feedback, when you have time ? | |
| 17:09:41 | opendevreview | sean mooney proposed openstack/nova master: move nova-ovs-hybrid-plug to deploy with spice and fix qxl default https://review.opendev.org/c/openstack/nova/+/940873 | |
| 17:11:05 | sean-k-mooney | melwitt: bauzas ^ squased into one comment, with release note updated. this is the review that was used for depends on before and i have abandoned the first patch | |
| 17:11:43 | sean-k-mooney | ok so next on my list is dans patch | |
| 17:12:04 | melwitt | sean-k-mooney: cool, thanks. will look | |
| 17:40:43 | sean-k-mooney | dansmith: bauzas im good with https://review.opendev.org/c/openstack/nova/+/942214 | |
| 17:41:14 | sean-k-mooney | just waiting on zuul beofre +w | |
| 17:41:27 | sean-k-mooney | with that said | |
| 17:41:51 | sean-k-mooney | it would be nice to see this used in https://review.opendev.org/c/openstack/nova/+/940642 | |
| 17:41:55 | sean-k-mooney | before we merge | |
| 17:42:09 | sean-k-mooney | so perhaps we shoud wait to merge until the other patches are on top | |
| 17:42:43 | dansmith | yep, fine to wait until it's used | |
| 17:42:50 | bauzas | sure, I'm working on the rebase | |
| 17:42:59 | bauzas | and then I'll need to end for the day | |
| 17:56:26 | gmann | In case anyone interested, TC is short of one candidate for this election. nomination ending in ~6 hrs from now https://governance.openstack.org/election/ | |
| 18:00:09 | dansmith | gmann: a non-redhat person is needed I assume :) | |
| 18:02:17 | gmann | dansmith: I think we still have one member capacity for RH member. slaweq is not re-running and no new RH member nominated yet | |
| 18:07:08 | MengyangZhang[m] | sean-k-mooney: I may need some help with implementing this min version check you mentioned for this patch https://review.opendev.org/c/openstack/nova-specs/+/932653. I have two ideas to do this:... (full message at <https://matrix.org/oftc/media/v1/media/download/AViM5KuzefB-19EfrDbw71k64XnKJJpP_G9sobaeS8NH-AJhP8DfPwD665n9DmazUuyKEk2lk1KiimNHIqjb0xpCeVZ31wDgAG1hdHJpeC5vcmcvcUdQVElMSnlsTUNLTWFJUVFDaFpmdERR>) | |
| 18:09:00 | sean-k-mooney | MengyangZhang[m]: oh so you cant really do that properly. my expection was cidner qos would never change out side of spawn/attach or perhaps volume retype | |
| 18:09:38 | sean-k-mooney | we coudl do it for spawn and attach in https://github.com/openstack/nova/blob/master/nova/compute/api.py | |
| 18:09:56 | sean-k-mooney | but cidner will end up bypassing any proection we put in place... | |
| 18:10:28 | sean-k-mooney | so im not sure what to do about that | |
| 18:10:54 | sshmlbrg | Hi? | |
| 18:11:07 | sean-k-mooney | sshmlbrg: o/ | |
| 18:11:24 | sshmlbrg | I have a question about the 'attach volume to shelved instance' functionality. How does it work if an instance in the 'shelved_offloaded' status has no availability zone, but when attaching, the availability zones of the instance and the volume are checked? The documentation states that this functionality works starting from microversion 2.20. | |
| 18:12:28 | sean-k-mooney | sshmlbrg: i dont think we supprot attach ro deation for shleve_offloaded but i would have to check | |
| 18:13:29 | sshmlbrg | ok, thanks | |
| 18:13:43 | sean-k-mooney | maybe we do i might be confusing that with snapshosts | |
| 18:14:34 | sshmlbrg | https://docs.openstack.org/api-ref/compute/?expanded=attach-a-volume-to-an-instance-detail#attach-a-volume-to-an-instance | |
| 18:14:47 | sean-k-mooney | ok so yes we do suprot it basedon the api refe as you said form 2.20 | |
| 18:15:01 | sean-k-mooney | you were asking about aviablity zone checks | |
| 18:15:13 | sshmlbrg | but it doesn't work | |
| 18:15:31 | sean-k-mooney | so by default htere are no aviablity zone checks for nova and cinder voluems. | |
| 18:15:46 | sean-k-mooney | we have a config option to opt into the non default beahvior of preventign cross az attach | |
| 18:16:18 | sean-k-mooney | its possible this only works when cross az atach is allow or when an instance is pinned to an az | |
| 18:19:53 | sean-k-mooney | ill see if i can quickly test it | |
| 18:20:27 | sshmlbrg | But this function lacks a cross-AZ check, and we proceed to compare the availability zone of the volume and the instance. https://github.com/openstack/nova/blob/master/nova/compute/api.py#L5143 | |
| 18:22:07 | sean-k-mooney | so cross_az attach is a comput enode option | |
| 18:22:19 | sean-k-mooney | a shevle offloaded instance does not have a compute service | |
| 18:22:41 | sean-k-mooney | so you cant actuly reason about if this shoudl or shoudl not work | |
| 18:23:50 | sean-k-mooney | the az check i enabeld by this check https://github.com/openstack/nova/blob/master/nova/compute/api.py#L5065 | |
| 18:23:56 | sean-k-mooney | *this default | |
| 18:24:02 | sean-k-mooney | because we are not passsing that variable | |
| 18:24:35 | opendevreview | Sylvain Bauza proposed openstack/nova master: Add a new ImagePropertiesWeigher https://review.opendev.org/c/openstack/nova/+/940642 | |
| 18:24:36 | opendevreview | Sylvain Bauza proposed openstack/nova master: per-property ImageMetaPropsWeigher https://review.opendev.org/c/openstack/nova/+/941601 | |
| 18:24:47 | bauzas | dansmith: sean-k-mooney: rebased as asked | |
| 18:25:27 | sshmlbrg | Then, should we disable this option so that attach works for shelved_offloaded VMs? | |
| 18:25:51 | dansmith | bauzas: okay did you want me to make the mods to use the new method? | |
| 18:26:03 | sean-k-mooney | there is more context here | |
| 18:26:24 | sean-k-mooney | sshmlbrg: https://github.com/openstack/nova/commit/07a24dcef7ce6767b4b5bab0c8d3166cbe5b39c0 | |
| 18:27:20 | sshmlbrg | i need a few minutes to get it :) | |
| 18:28:39 | sean-k-mooney | sshmlbrg: it looks like the curent check was added to fix https://bugs.launchpad.net/nova/+bug/1694844 | |
| 18:28:57 | sean-k-mooney | but it may have broken seveled atatch in the process | |
| 18:29:59 | sean-k-mooney | skimming the patch it maybe looks like the intent was to fall back to the default schduler zone | |
| 18:30:31 | sean-k-mooney | i think in this sepcific case it woudl be valide to pass false | |
| 18:31:00 | sean-k-mooney | if an donly if instnace.az was None in either the request spec or the instance table in teh cell db | |
| 18:31:35 | sean-k-mooney | basically if the isntance is shelve_offloaded. and it not pinend to any az | |
| 18:32:04 | sean-k-mooney | then we can possibly disable the afinity check | |
| 18:32:33 | sean-k-mooney | but that may lead to issue unshevling | |
| 18:32:46 | sean-k-mooney | unless we pinned the shleved instance to the relevent az | |
| 18:33:10 | sean-k-mooney | that is only vailid to do however if cros_az_attach=false | |
| 18:34:17 | sean-k-mooney | since we can now unshlve to an az | |
| 18:34:27 | sshmlbrg | Yes, and also, we can unshelve the VM to another AZ, and I’m not sure how the volumes will behave in that case. | |
| 18:34:45 | sean-k-mooney | the workaround for tha twould be to return an error and make the user explictly request the az they want to unshvle to and that woudl have to match the volume az | |
| 18:35:07 | sean-k-mooney | sshmlbrg: its blocked if you use the non default beahvior | |
| 18:35:30 | sshmlbrg | ok | |
| 18:35:34 | sean-k-mooney | sshmlbrg: teh reals fix is to delete the ablity for nova to prevent cross_az entirly | |
| 18:35:44 | sean-k-mooney | that never shoudl have been a per compute config option | |
| 18:36:02 | sean-k-mooney | it should be a attibute on the cinder volume | |
| 18:36:25 | sean-k-mooney | i.e. when attaching a volume you shoudl be able to choose if cross az storage is allowed or not | |
| 18:36:35 | sean-k-mooney | the reason it snot that way, beyond legacy | |
| 18:36:55 | sean-k-mooney | is as a end user you dont knwo if the strage backend is accable from the current host | |
| 18:37:41 | sean-k-mooney | its tricky | |
| 18:38:35 | sshmlbrg | ok, i hope i got it, need to summarize it. Is it bug or ...? | |
| 18:49:35 | sean-k-mooney | its proably a but im just not sure how to fix it | |
| 18:50:06 | sean-k-mooney | im inclided to say pass false and then requrie pepoel to unshlve to the same az fi thats how the clodu is confiugred | |
| 18:51:08 | sean-k-mooney | we shoudl have a better solution to this, that the problem with config driven api bevhior and why we dont add it anymore if we can avoid it at all costs | |
| 18:53:30 | sshmlbrg | I was thinking about storing the old AZ, writing the AZ to it when shelving, and releasing it when unshelving. Then, when attaching the volume, we could check that specific availability zone. | |
| 18:54:04 | sean-k-mooney | so that not correct | |
| 18:54:25 | sean-k-mooney | instnace that dont request a az shoudl not be pinned to one by default | |
| 18:54:32 | sshmlbrg | understand why | |
| 18:55:20 | sean-k-mooney | if they have a cidner volume and land on a host with cross_az_attach=false and it does not violate the requirement nova will pin it | |
| 18:56:34 | sean-k-mooney | sshmlbrg: did the instance have a voluem before it was shelved? | |
| 18:56:50 | sshmlbrg | yes, volume-backed instance | |
| 18:57:03 | sean-k-mooney | ok then it should be pinned already | |
| 18:57:21 | sean-k-mooney | so the bug is that its proably not usign the az form the request spec if its not set in the host | |
| 18:57:28 | sean-k-mooney | * in the instance table | |
| 18:58:07 | sshmlbrg | yes | |
| 18:58:37 | sean-k-mooney | ok so tha that specific edge case is fixable | |
