dulekgeguileo: I'm asking because I see 315541 as a rather dangerous one. And it breaks Python's explicit is better than implicit.12:03

geguileodulek: And we have a lot of code duplication12:04

openstackgerritPranali Deore proposed openstack/cinder: Add logging when filtering returns nothing  https://review.openstack.org/30628512:04
geguileodulek: And for every new OVO we introduce we introduce even more12:04
geguileodulek: Well, those are mostly comments12:04
geguileodulek: Because we almost had none of those12:04
geguileodulek: And when I add the Cluster OVO it removes a lot of code12:05
geguileodulek: Because the Cluster create, save, delete, don't need to be added12:06
dulekYou're probably right on the comments… Okay, I'll take look on whole chain to judge that.12:06
geguileodulek: The chain is broken right now...12:07
dulekSure, but it still should give me a better picture.12:07
geguileodulek: Because I had a longer chain, but with the job distribution changes I just have a couple so that we could check the general idea of the new stuff12:07
geguileodulek: Ok12:07

smcginnisdulek: Ah, OK.13:51
johnthetubaguyildikov: I just think we need a little more background on what its doing, I think thats technically a cinder only API13:51
ildikovjohnthetubaguy: if possible I would like to minimise the round trips between Nova and Cinder13:52
*** jbernard_ is now known as jbernard13:52
ildikovjohnthetubaguy: so I'm definitely on the side of getting more background and do what's necessary13:53
johnthetubaguyildikov: I suspect we really should be doing more storing of the volume info in the BDM, to stop all the extra cinder calls, but thats a different thing, but agreed!13:54
ildikovjohnthetubaguy: from the weekly meetings it seems to me that we're on the way to understand how Cinder and Nova interacts as it got a bit out of control13:54
johnthetubaguyyeah, +113:54
ildikovjohnthetubaguy: and also we should keep things on Cinder side that belongs there13:55
ildikovjohnthetubaguy: whenever and wherever w can simplify Nova and clean up the responsibilities we should do that13:55
johnthetubaguyildikov: +113:56
smcginnisildikov: Definitely +113:56
smcginnisI think the lines of responsibility really got blurred.13:57
smcginnisOr started out that way with cinder coming out of nova.13:57
jgriffithsmcginnis: nah.. back then it was easy :)13:57
smcginnisjgriffith: Heh, no doubt.13:57
johnthetubaguywe didn't do stability or error handling then, life was easy going13:57

ildikovjgriffith: or at least I would be happy to chime in :)14:01
jgriffithildikov: I keep reworking things14:01
jgriffithildikov: so what I did last night was try and simplify things under the assumption of no multi-attach and using nova as is today14:02
*** ducttape_ has joined #openstack-cinder14:02
jgriffithildikov: I think have a patch for nova, cindreclient, and another for cinder to implement a new way of attach/detach14:02
ildikovjgriffith: sure, but for instance I can play with unit tests in one patch while you're working on refactoring some items, etc14:02
jgriffithildikov: keeping the cinder code so that an older nova will stil work14:02
jgriffithildikov: oh... well if someobdy wants to volunteer to help on the unit test madness (and it is madness) I'll push some WIP code up when I get to my desk14:03

jgriffithildikov: haha... yeah, they're pretty awful14:05
smcginnisjgriffith: Do they block it now?14:05
jgriffithsmcginnis: yeah, because theyr'e not unit tests at all14:05
smcginnisOh, I meant the xenial comment.14:05
jgriffithsmcginnis: oh sorry :)14:05
smcginnisjgriffith: But yeah, I get you on the "unit" tests.14:06
jgriffithsmcginnis: so they added a check now and it stops devstack from running, but you can set "FORCE" and it'll work14:06
savihousmcginnis: WRT dulek's note regarding the non-voting tag (ZadaraStorage CI); is there any concern with it? I've sent out earlier todat a voting rights nomination request for it ..14:06

*** baumann has quit IRC14:06

*** dansmith is now known as Guest2162114:12
ildikovsmcginnis: jgriffith: two items are in question, which is the volume_snapshot_create API in Nova and the other one is a Cinder API microversion which we think will be required for multi-attach14:12
*** jwcroppe_ has joined #openstack-cinder14:13
ildikovsmcginnis: jgriffith: from the two items myself I'm certainly not educated on the volume_snapshot one14:13
smcginnisildikov: Yeah, we'll need a microversion bump for the API changes.14:13
ildikovsmcginnis: jgriffith: do you happen to have any background on that one?14:13
* smcginnis looking now...14:13
*** Guest21621 is now known as dansmith14:14
*** diogogmt has joined #openstack-cinder14:14

*** jwcroppe has quit IRC14:14
*** julim has quit IRC14:15
smcginnisildikov: So the snapshot question is around the Nova side with OS assisted snapshot? Am I understanding that right?14:16
*** takedakn has joined #openstack-cinder14:16
ildikovsmcginnis: kind of yes14:16
*** merooney has quit IRC14:16
jgriffithildikov: I think the current proposals for multi-attach are all wrong14:17
ildikovsmcginnis: johnthetubaguy pointed out that this snapshot API is mainly for Cinder to use14:17
smcginnisildikov: So that part I think would be tricky (OS assisted) but on the cinder side we can snap no problem.14:17
jgriffithildikov: I don't think it needs be that hard14:17
jgriffithjust a second... have to pay attention to this part of the meeting :)14:17
*** sheel has joined #openstack-cinder14:18
ildikovjgriffith: well, there aren't too many restrictions there by now I think, but we can discuss14:18
ildikovsmcginnis: in what sense do you mean it's tricky?14:18
smcginnisildikov: If it's not OS assisted then we can just snap the volume, so no big deal there.14:20
smcginnisildikov: But if it is OS assisted...14:20
smcginnisildikov: And we have multiple attachements...14:21
smcginnisildikov: Then it seems we would need some kind of coordination across the multiple attached OS's for that.14:21
ildikovsmcginnis: in what cases OS assisted is used?14:21
smcginnisildikov: Just not a 1:1 relationship anymore.14:21
smcginnisildikov: I don't have a lot of experience there, so maybe someone else can chime in.14:21
smcginnisildikov: But from my understanding, the OS will do some work to flush IO so we can make sure the snapshot is good consistent data.14:22
*** lprice has joined #openstack-cinder14:22
smcginnisildikov: Without OS involvement there is no guarantee that all IO has been written to disk at the time it is snapped.14:23
ildikovsmcginnis: is that used for "local" volumes as pointed out in the comments?14:23
*** diogogmt has quit IRC14:23
ildikovsmcginnis: or it can be applicable for all types?14:24

*** jungleboyj has quit IRC16:03
ildikovwow, I did look that deep into it16:03
ildikovI only started to wonder why we're not using the regular attach for BFV, at least to the case when we're attaching an already existing Cinder volume at boot time16:04
*** jungleboyj has joined #openstack-cinder16:04
hemnaso, the other thing is16:04
hemnachanging that code causes a failure, because check_attach is called later and the volume is already in attaching16:04
hemnaso we'll have to change other places to account for it16:04
hemnabut maybe that's not such a bad thing16:04
hemnayet another race in nova->cinder16:05

ildikovbut the second check_attach should not be there at all16:06
ildikovI would assume at least16:06
ildikovI mean we have an option to use the regular attach flow I would guess, but maybe BFV is too messed up for that already16:07
hemnathat's the call that gets made16:07
hemnaduring BFV16:08
ildikovif not then we need to figure out when to call reserve and remove all the check_attach calls16:08
hemnahave to figure out how to get that flag to be false16:08
hemnait defaults to True16:08
hemnait would be nice to eliminate it all together from that function16:08
ildikovbut do we need that check_attach call?16:08
hemnabut I could be starting down a rabbit hole16:08
hemnanot with my changes16:08
ildikovI mean by using reserve everywhere we should be good with the True case16:09
hemnaI just don't know all of the other cases to this attach() call where they expect check_attach to happen16:09
ildikovand we don't need it when it's set to False anyway, which will be the moving cases I guess we talked about yesterday16:09
ildikovcannot we use the functest suit or tempest to identify when that thing is called?16:10
*** dustins has joined #openstack-cinder16:10

*** raunak has joined #openstack-cinder16:13

ildikovso in Nova we check volume status whether it's available or not16:26

eharneysmcginnis: i'm curious about https://review.openstack.org/#/c/319965/  -- posted a question there when you have a moment16:31
ildikovhemna: ok, so on your diagram for attach there is a second check_attach call after reserve: https://drive.google.com/file/d/0B1Kp6K43HLHyRkFMZHVHWDJ3amM/view?pref=2&pli=116:31
hemnayah it's done a few times :(16:32
hemnaand that diagram is just for normal volume attach16:32
hemnanot BFV16:32
ildikovhemna: check_attach checks whether the volume is 'available' or not16:32
ildikovhow it gets through the second check after reserve?16:32
hemnait shouldn't need to16:33
ildikovor that's another volume status that reserve sets?16:33
hemnanova shouldn't get that far if it didn't call reserve at the start16:33
hemnaunless that code is called from some other workflow we don't know about16:33
hemnawhich is always what worries me in Nova.16:33
hemnareserve changes the status field16:34
ildikovI just would like to understand what Nova checks there as it checks something else and not what reserve modifies16:34
ildikovhmm, we use the status field as well16:34
ildikovI mean in check_attach16:34
hemnait looks at the volume['status'] field16:35
hemnawhich is what reserve changes to 'attaching'16:35
*** sdake_ has joined #openstack-cinder16:35
ildikovbut check_attach explicitly checks for 'available' state if I saw correctly16:35
*** IlyaG has joined #openstack-cinder16:36

hemnamust be passed in as False16:37
*** GB21 has joined #openstack-cinder16:37
ildikovok, most probably that's what's missing, although I thought that flag is false for the cases, where we have the volume attached for some reason like for evacuate16:38
*** sdake has quit IRC16:38
*** IlyaG has quit IRC16:38
ildikovok, right do_check_attach is set to fals for the normal case16:40
ildikovand it's set to true for BFV if I saw correctly, but if we do reserve or try to use the normal attach flow that's not needed either16:40

eharneysmcginnis: that's what i was trying to figure out -- my only guess is that it worked w/ an older version of mock17:35
eharneysmcginnis: i'm hoping someone has a counterexample for me17:36
smcginniseharney: Looks like gate is using 2.0.0: http://logs.openstack.org/04/319804/1/check/gate-cinder-python27-db/dc79161/console.html#_2016-05-23_09_50_01_59017:36
*** jwcroppe_ has quit IRC17:37
smcginnisJust a little confused how it was there in the first place.17:37
eharneysmcginnis: the gate used to not install the newest version from upper-constraints, right?17:37
smcginniseharney: I think you're right.17:37
eharneysmcginnis: requirements only demands 1.2 as a minimum17:37
smcginniseharney: But if it's now using 2.0, why wasn't every Jenkins run failing with the invalid call in there?17:38
eharneysmcginnis: do we know when the invalid call was introduced?17:38
eharneysmcginnis: https://review.openstack.org/#/c/308626/  right?  that was only merged on may 20...17:39
eharneyand i don't see any other places that this hacking check would have caught17:40
smcginniseharney: Yeah, that should be it.17:40
smcginniseharney: But even that patch that added it was using 2.0 - http://logs.openstack.org/26/308626/7/check/gate-cinder-python27-db/6061ebc/console.html.gz#_2016-05-20_17_46_47_71617:40
smcginniseharney: So I'm just confused then how that didn't fail in the gate.17:41
*** timcl has joined #openstack-cinder17:41
smcginnisUnless 1.3 fails on the invalid call, but 2.0 has a regression where it doesn't...17:41
eharneyhmm, good question17:42
eharneysmcginnis: mock 2.0.0 added assert_called_once17:42
smcginniseharney: LOL17:42
eharneyso it's not a regression, it's just a totally incorrect hacking check17:43
smcginniseharney: OK, yep. Let's pull that out of there. :)17:43
smcginniseharney: But in the mean time, we probably should request the mock minimum be raised to 2.0 so it's not an issue.17:43
eharneysmcginnis: given that this has only occurred once... i'm not sure how interesting the mean time is  (i also have no idea how hard it is to request an openstack-wide bump to 2.0)17:44
smcginniseharney: True. I'll probably request it and see how it goes.17:44
smcginniseharney: But I don't mean reverting the hacking check should pend on that happening.17:44
eharneysmcginnis: this is also kinda amusing: https://review.openstack.org/#/c/200562/17:45
smcginniseharney: Just that it probably should be done as well so if someone adds that call, folks with an older mock installed don't fail.17:45
