patrickeastildikov: kinda around, whats up?18:11
* patrickeast looks at the review18:11
ildikovpatrickeast: the above review came up on our Cinder-Nova meeting today18:11
ildikovpatrickeast: stvnoyes would be happy to hand it over to experts :)18:12
ildikovpatrickeast: I added a comment to it, I believe jgriffith is also planning to look into it18:12
patrickeastildikov: ew yea, that ones kind of a pain18:12
ildikovpatrickeast: basically my thinking is to figure out what the drivers need to provide and fix this for lvm18:13
ildikovand also give clean instructions to the drivers on what we expect there18:13
ildikovI don't know whether this approach could work, but I cannot think of anything else at this point18:13
patrickeastildikov: yea, thats tricky because it leaves a lot up to interpretation and relies on like client (nova/ironic/etc) sychronization to prevent things from breaking18:14
patrickeastildikov: in theory the idea that the drivers knows when its safe to detach is perfect.. but the time it says its safe and the time the client does something about it with os-brick are different enough to open it up for some sketchy stuff18:14
jgriffithpatrickeast does it though?18:15
patrickeastjgriffith: yea, if you are detaching, and someone else attached a new volume, that bool of "no more volumes" from the driver may not be correct by the time it reaches the client18:15
ildikovpatrickeast: for multi-attach surely18:15
patrickeasteven in single-attach scenarios18:15
ildikovpatrickeast: we hit this not with lvm and live_migrate18:16
jgriffithpatrickeast Yeah... I suppose that's reasonable; but I'm not sure I see how it's problematic?18:16
ildikovpatrickeast: oh, ok, I missed the nit per volume aspect of this I think :(18:16
jgriffithpatrickeast worst case scenario you're stale and you "think" you need to keep it around18:16
jgriffithat some point though we have a sequential delete of the attachment record18:17
jgriffithand vice versa18:17
jgriffithor is your point that we have the madness and limbo of being stuck over in brick land somewhere?18:17
patrickeastjgriffith: mostly that, it leaves us open to all the race conditions and stale volume attachments we have today (well, new a different ones maybe)18:18
jgriffithhmmm... I guess I don't understand those races then18:18
dhineshany idea, when can new drivers can be submitted for queens release or when the code can be submitted for reviews?18:18
jgriffithbecause now, we're requiring a unique atachment for every connection to solve many of those races.  BTW, I'm not discounting what you're saying, I just want to fix this and get it merged :)18:19
jgriffithand I may not have the right insight to do that based on what you're saying18:19
ildikovpatrickeast: would that make sense to explore the scenarios for like Pure and lvm and see what we could come up with that solves the issue?18:19
patrickeastjgriffith: one sec, i'm double checking how this ended up being implemented18:20
patrickeastjgriffith: want to make sure i'm about to explain something correctly18:20
jgriffithpatrickeast well that's actually a good idea :). With all the churn I'm not sure I remember myself :)18:20
patrickeastjgriffith: haha yea, as i was looking i saw new things18:21
patrickeastjgriffith: mmm so it kinda looks like the "has_shared_attachment" only means multi-attach right now? I remember there being something about like the host-based targets w/ multiple luns and reporting whether or not it was time to tear that down18:24
patrickeastjgriffith: and at some point there was a like flag we needed to send to nova (or whoever) to indicate they needed to do sequential attach/detach on a initiator-wide basis...18:25
*** eharney has quit IRC18:25
*** kaisers_ has quit IRC18:25
patrickeastjgriffith: my main concern is that some of these are bleeding together18:25
ildikovpatrickeast: is this all independent from the new attach API?18:26
patrickeastildikov: nah, these were things that were part of the attach api18:27
ildikovpatrickeast: you mean the new one18:27
patrickeastildikov: haha, yea :)18:28
ildikovpatrickeast: ok :)18:28
ildikovpatrickeast: got unsure as we never really fixed the issues just brainstormed about it18:28
jgriffithpatrickeast yeah, so let's ignore that patch for a second18:29
jgriffithpatrickeast johnthetubaguy raised a concern about shared attachments on the nova side a while back18:29
jgriffithjust in a standard non-multi-attach and non-migrate case18:29
patrickeastyep18:30
jgriffithso I had some comments in the code and such pointing out that there was an identified issue/concern18:30
jgriffithbut that I had no idea WTF to do about it or exactly how it all worked :)18:30
jgriffithfor LVM and SolidFire for example the only time this matters is multi-attach or the special case of live-migration (although it's too bad we do LM the way we do)18:31
ildikovjgriffith: you mean having the two connections exist simultaneously?18:31
jgriffithso the problem for me is; I'm stuck, only because I don't know enough about how/if cinder drivers share a single target for multiple volumes18:31
*** jwcroppe has joined #openstack-cinder18:31
jgriffithildikov yes18:31
patrickeastjgriffith: yea i think its only for some backends... but the more i'm looking at this the more i think it may not matter, without any os-brick changes things might just work the way they did before18:31
ildikovjgriffith: as you need to switch over I'm not sure how we could do that in any other way18:32
jgriffithpatrickeast so my thought was that if nothing else we're at status-quo18:32
patrickeastjgriffith: yea, i think so18:32
jgriffithdetach it and reattach it for real... but anyway, different discussion18:32
jgriffithpatrickeast the one thing I did do was add the ability to return the 'safe-to-detach'18:32
jgriffithwhich defaulted to true18:33
patrickeastjgriffith: ok, which means i'm not so crazy,  i'm sticking to my guns on this concern that the return value from terminate connection is mixing up two things then18:33
jgriffiththen the drivers that had problems or needed something different could change that18:33
patrickeastjgriffith: imo the distinction between a volume being connected more than once and a connection being shared should be more clear18:33
jgriffithpatrickeast so yeah, the terminate connection thing is the outlier here that screws everything up due to live-migration actually holding 2 attachments at once without actually creating new attachment records18:33
jgriffithpatrickeast I think that's a pretty valid point18:34
patrickeasthaha yea, live migration is definitely the outlier18:34
jgriffithI'm beginning to wonder if what we actually need is just a "shared" flag in the attachment object18:34
ildikovpatrickeast: so shared connection can be two attachments to two different volumes on one back end?18:34
patrickeastjgriffith: were there plans to change it to be less insane?18:34
patrickeastildikov: yea18:35
jgriffiththat would make it clear whether it's multiple connections vs shared connections18:35
jgriffithand that could be used by LM to get around some of the ambiguity18:35
patrickeastildikov: and alternatively two connections to a single volume might actually be more than one connection (some systems can setup distinct targets)18:35
*** ChubYann has joined #openstack-cinder18:35
patrickeastjgriffith: +118:35
jgriffithpatrickeast I believe 3par works that way for example18:35
jgriffithildikov ^^18:36
jgriffithOk, let me look at the possibility of adding another field.  Of course with micro-versions and object-versions and umpty-squat versions that might be much easier said than done18:36
ildikovpatrickeast: I know that part and that does not cause issues, so I just ignored that case for now :)18:37
patrickeastjgriffith: haha true18:37
ildikovjgriffith: I'm not sure I fully followed the flag part18:37
*** Swanson has joined #openstack-cinder18:38
*** gus has quit IRC18:38
ildikovre the multiple vs shared connections18:38
jgriffithildikov the idea being that the attachment object actually has an indication of whether it's using a shared-connection18:38
jgriffithildikov in other words are there multiple attachments, or are we sharing a single connection across multiple hosts18:38
patrickeastjgriffith: i could have sworn we did that at some point, or talked about it18:39
jgriffithpatrickeast I thought so too... but who knows18:39
*** salv-orl_ has quit IRC18:39
*** salv-orlando has joined #openstack-cinder18:39
ildikovjgriffith: would that describe the nature of the driver? or the actual connection?18:40
*** gus has joined #openstack-cinder18:40
patrickeastildikov: both i guess, its a hint to the client as to how they should handle its connection workflow18:40
jgriffithildikov both, but honestly I need to look at things a bit to see if it even works anyway :)18:41
patrickeastildikov: which i think is (and may be) different than the returned value from attachment delete18:41
jgriffithhmmm18:42
ildikovalthough if the problem can be per back end it's pretty tough to figure out just by the notion that soemthing is shared18:42
ildikovI mean if the flag only tells about behavior and not actual state18:43
jgriffithhttps://github.com/openstack/cinder/blob/master/cinder/volume/manager.py#L430618:43
ildikovI guess I'm overcomplicate this, but someone need to represent johnthetubaguy's concerns :)18:43
*** salv-orlando has quit IRC18:43
jgriffithwas what I'd originally hoped would solve this18:43
jgriffithI need to check out for a bit, be back in a bit18:46
ildikovI guess we're a bit stuck on what we actually want that flag to represent18:46
jgriffithildikov FTR I'm not stuck at all :)18:47
jgriffithI know exactly what I want it to do18:47
ildikovthen just my thoughts got stuck :)18:47
jgriffithtell the caller whether they can safely nuke the connection on their side or not18:47
jgriffithNah, I over simplify :)18:47
ildikovok, then make me understand the middle version, when you're back :)18:48
jgriffithhaha18:48
ildikovI hope it's not an all afternoon meeting series you'll be back in a bit form... :)18:48
jgriffithok18:48
ildikovok, I admit my brain is not the fastest on the planet, but not hopeless either :)18:48

jgriffithildikov back19:46
jgriffithildikov so the difficulty I'm having is i don't know "what" problem people want to solve here19:47
ildikovlike the live_migration issue19:47
jgriffithok, so is that what we want to solve?19:47
ildikovthat is one appearance of the issue we want to solve19:48
ildikovaccording to earlier discussions in case of different back ends we migh tend up with different scenarios19:48
ildikovbut for lvm for now that's what I would like to solve19:48
ildikovI mean figure out what to do on high level and solve the lvm specific parts in lvm I guess19:49
