ildikovgood morning :)16:01
ildikovlet's wait a minute to see if anyone else shows up16:02
stvnoyeso/16:02
ildikovok, let's deep dive in :)16:03
ildikovso the list of merged patches are looking good: https://review.openstack.org/#/q/topic:bp/cinder-new-attach-apis16:03
hemnao/16:03
ildikovhemna's os-brick quick fix for the target_lun casting got merged as well IIRC16:03
*** MarkBaker has quit IRC16:03
ildikovso we're slowly progressing towards having a working attach PoC16:04
ildikovmriedem has patches up to figure out what to do with the microversion discocery16:04
hemnaI put up a patch to the brick cinderclient extension yesterday16:04
hemnathat uses the new attach/detach workflow16:05
smcginnishemna: Do you have a link to that?16:05
ildikovhemna: do you have a link handy?16:05
smcginnisjynx16:05
ildikovsmcginnis: ;)16:05
hemnahttps://review.openstack.org/#/c/469594/16:05
ildikovhemna: tnx16:05
*** MarkBaker has joined #openstack-meeting-cp16:06
ildikovhemna: did you run into any issues to discuss here?16:08
hemnanot after the fix I put in for the lun id in brick16:08
ildikovok, cool16:08
ildikovBTW, how does that work with brick, do we need a release now for that fix?16:09
mriedemyes, and min version bump in g-r16:09
mriedemif you need nova to use it16:09
jgriffithI think that's just the extension no hemna ?16:10
hemnajgriffith, correct16:10
jgriffitherr... you mean the lun-id fix16:10
hemnawe need a new release of brick yes16:11
hemnato get that fix in place and then bump the min version for nova16:11
mriedemwhich is the os-brick patch?16:11
ildikovwhen can we have a release?16:11
mriedemhttps://review.openstack.org/#/c/468108/16:11
mriedemright? ^16:11
hemnayup16:11
mriedemyou can propose a release at any point16:12
ildikovI was just wondering whether there's anything we're waiting on to get in before releasing or anything like that16:13
ildikovhemna: smcginnis: can either of you take care of the brick release to get the fix available?16:15
smcginnisThere are a bunch of open reviews of os-brick. Probably the only one that might be good to get in first would be for anew connector for lustre.16:15
smcginnisBut I'm not sure if that has the rest of the things in place that we really need to wait for that.16:16
hemnasmcginnis, ildikov we can work on finishing up reviews and get a new release out soon16:16
smcginnisyep16:16
ildikovsounds good, tnx16:16
ildikovis there anything with microversions that we should touch base on here?16:17
ildikovbesides the patches from mriedem I mentioned above16:18
jgriffith*should*?16:18
jgriffith:)16:18
mriedemthe attach poc needs to be rebased on those16:18
ildikovif there's nothing else with brick beyond, plz review! :)16:18
jgriffithWe have Cinder side things to discuss, but yeah I think mriedem 's solve the problem for now16:18
mriedemi haven't looked at stvnoyes' live migration poc yet16:18
jgriffithmriedem yeah, I'll do that this morning16:18
ildikovstvnoyes: how's the testing going with that?16:19
jgriffithcinder needs to fix the versioning stuff long term though16:19
mriedemstvnoyes opened 2 bugs about regressions in rolling back a live migration, one i invalidated since i didn't see the issue in the code, and one i have a fix up for16:19
ildikovjgriffith: +116:19
stvnoyeshold off on the migration rv. I found some problems during testing and if i can get devstack working after an update I'll get back to it16:19
mriedemok16:19
stvnoyesmriedem: i responded to the bug, it wasn't in my patches16:20
stvnoyesthere is a problem there, (I checked github)16:20
mriedemstvnoyes: ok re-open the bug please16:21
stvnoyesand there's a couple of open issues in the PoC that I left comments for. they don't affect attach/detach but I hit them during migrate16:22
jgriffithstvnoyes I'll check them out16:22
stvnoyesback to New?16:22
ildikovstvnoyes: the error handling bits?16:22
stvnoyesok, back to Confirmed...16:23
stvnoyesI don't recall exactly how I hit those issue. It could have been during rollback.16:23
stvnoyesthe PoC issues... ^16:23
mriedemstvnoyes: back to new, or just link me16:24
ildikovstvnoyes: there are some issues with error handling in that PoC, I found some of those issues as well earlier, but you should not hit them with migrate I would think16:25
ildikovstvnoyes: or well, depends on why you're rolling back I guess16:26
stvnoyesthey were pretty simple bugs, definitely issues16:26
*** mgiles has quit IRC16:28
ildikovthe PoC still needs work, so we'll look into that with jgriffith16:28
mriedemok this one https://bugs.launchpad.net/nova/+bug/169483416:28
openstackLaunchpad bug 1694834 in OpenStack Compute (nova) "libvirt rollback: destroy called with wrong number of args" [Undecided,Confirmed]16:28
stvnoyesy, that's the one16:28
mriedemok anything else for this meeting?16:30
ildikovI think we're mainly good for now16:30
ildikovonce the attach PoC is in a better shape we can think of how to deal with swap16:30
ildikovfor the new flow16:30
ildikovI would guess the live migrate issues can be dealt with offline in case there are no more confusions on the bug report to discuss16:31
ildikovso next steps are to fix the comments in the attach PoC and move it on top of Matt's micrvoersion patches16:31
ildikovfix live migrate issues in parallel and get the brick release out as well16:32
ildikovso I think we have enough home work for next week16:32
ildikovthe Cinder side of microversions can also be discussed outside of this meeting16:33
ildikovanything else I'm missing?16:33
ildikovor that someone would want to raise to discuss?16:33
ildikovI take it as a no16:34
ildikovthanks all!16:34
ildikovkeep on reviewing and testing :)16:34
ildikovhave a good day! :)16:34
