stvnoyeso/16:01
xyang1Hi16:01
ildikovok, let's start :)16:02
ildikovthe open reviews are here: https://review.openstack.org/#/q/topic:bp/cinder-new-attach-apis+status:open16:02
ildikovsmcginnis: I payed attention to 'open' this time :)16:02
ildikovjungleboyj: did you get there yesterday to cut a new client release?16:02
jungleboyjildikov:  I did.  I haven't checked to see if it went through.16:03
jungleboyjildikov:  https://review.openstack.org/#/c/499282/16:03
jungleboyjNot yet.16:03
ildikovok, I guess it shouldn't take that long16:04
jungleboyjsmcginnis:  Anything you can do to get that through?16:04
ildikovso until we don't have the new client we still won't see clean test runs on the gate, but we're pretty close now16:05
ildikovmriedem: I proposed the spec for Queens16:06
ildikovmriedem: also commented on the begin_detaching one16:06
mriedemok16:06
smcginnisildikov, jungleboyj: I'll push that through. No need to hold off at this point.16:07
ildikovsmcginnis: sounds good, thanks!16:07
ildikovsmcginnis: do we need a g-r patch too?16:07
smcginnisildikov: The new package will automatically generate an upper-constraints update, but yes, we will need to raise the minumum g-r if we want to make sure the right version is always used.16:08
ildikovsmcginnis: ok, got it16:08
ildikovsmcginnis: jungleboyj: will either of you handle that?16:09
smcginnisI can if jungleboyj doesn't jump on it.16:09
jungleboyjsmcginnis:  Another learning op for me?16:09
smcginnisjungleboyj: Sure, we can work on that together.16:10
jungleboyjsmcginnis:  Thanks.  All new to me.16:10
ildikovjungleboyj: smcginnis: cool, thanks!16:10
ildikovbeyond this we have a bug report from stvnoyes on when to have the attachment_id appearing in the volume details16:11
mriedemjungleboyj: bumping a minimum version in g-r is new to you after all these years?!16:11
ildikovas currently we only have attachment_id when the attachment is crated and connected on both sides16:12
jungleboyjOh, in global-requirements.16:12
jungleboyjI guess not.16:12
smcginnismriedem: Looks like this should probably just be abandoned: https://review.openstack.org/#/c/466184/16:12
jungleboyjNow that I think about it.16:12
stvnoyesildikov- that bug was addressed by this - https://review.openstack.org/#/c/498055/ and was merged16:12
jungleboyjLet me go tackle it.  Just been a while.16:12
mriedemsmcginnis: i think i already -2d or abandoned another similar one for mitaka from him16:13
mriedemsomeone is playing the backport fork game16:13
ildikovsmcginnis: I asked Ashish in Boston to upload their code to see whether we can reuse anything for multi-attach16:13
smcginnismriedem: Annoyance level high.16:13
ildikovsmcginnis: mriedem: it's not for merge16:13
mriedemi realize16:13
mriedembut16:13
mriedemit's not helpful either16:13
smcginnisjungleboyj: We'll need the release go through first, then we can make the g-r bump Depends-On the upper-constraints patch.16:13
ildikovsmcginnis: mriedem: my bad, next time I will tell people to use an own repo for this purpose16:13
ildikovmriedem: and yeah, I didn't know in advance whether it will be or not... :)16:14
ildikovthe patch itself can be abandoned16:14
jungleboyjsmcginnis:  Ok.16:15
ildikovmriedem: I thought to look into the old multi-attach spec and re-propose an updated version for Queens16:15
ildikovmriedem: if you're not against the idea16:15
mriedemildikov: that's fine16:16
ildikovmriedem: ok16:16
ildikovstvnoyes: but you reported another bug since that16:18
ildikovstvnoyes: with attachment_id not in volume details until attachment_complete is called16:19
stvnoyesthat was https://bugs.launchpad.net/cinder/+bug/1713521 - where the attachment disappears after update but before complete16:19
openstackLaunchpad bug 1713521 in Cinder "v3 attach, volume shows no attachments for a short period during migrate" [Undecided,Confirmed]16:19
stvnoyesnot the actual attach, but how it is reported16:19
stvnoyesis anyone looking at that? I thought jgriffith would be interested, but it seems he's not around?16:20
ildikovstvnoyes: well, it's not there until complete, which means that for live_migrate there's a window where you don't have that data in the volume details16:20
stvnoyescorrect16:20
stvnoyesi would guess it also happens during attach, not just migrate (but I haven't checked that)16:21
stvnoyesif john's away, I'll take a look into it16:21
ildikovI think it's a bit of a philosophical question as well on when we want that data to be present16:23
ildikovas we're mostly using the volume ref on the Nova side I think it would make sense to have it listed from the moment of reserving the volume16:24
ildikovdoes anyone have a strong opinion on this?16:24
stvnoyesok, let me see why it's doing that. then we can have a better idea if what we should do16:25
stvnoyesif=of16:25
ildikovstvnoyes: sounds good, thanks!16:26
ildikovthat was it from me for today16:26
ildikovI hope the client gets through and we can get the reviews move forward too16:26
ildikovwould be great to have this in shape by the PTG and merge things there the latest16:27
ildikovso we can move to the multi-attach bits16:28
ildikovok, I think that's it for today then :)16:29
ildikovthank you all16:30
smcginnisThanks ildikov!16:30
ildikovkeep in touch on the channels till next week! :)16:30
