jgriffiththingee: avishay__ can eithe ro fyou explain to me what this actually "means"?03:54
jgriffiththingee: avishay__ there's no multi-attach, thus the described sequence isn't even valid03:54
jgriffiththingee: avishay__ and the bug should be that we don't allow volume->image for attached volumes period03:55
jgriffiththingee: avishay__ but wondering if I'm misreading something?03:55
avishay__jgriffith: checking03:55
*** avishay__ is now known as avishay03:55
avishayjgriffith: volume->image using the dd method makes no sense at all, but with a clone it does. not easy to differentiate.03:56
jgriffithavishay: hmm... so it's valid for one driver, but not another?  I thought we weren't going to do that sort of thing?03:56
jgriffithavishay: or am I still confused maybe?03:56
avishayjgriffith: i didn't say anything about we should do (yes we should have a common API that is not broken for most drivers), i said what makes sense in terms of not being broken :)03:58
jgriffithavishay: LOL03:58
avishayjgriffith: if all you're doing is taking a snapshot, that's fine. if you're dd'ing while writes are coming in, that's not going to work03:58
avishayjgriffith: how to handle that is another issue03:58
jgriffithavishay: hmm... I don't think that change should have ever landed03:58
jgriffithavishay: and I surely don't think it should be backported to Kilo, Juno and Icehouse :(03:59
*** asselin_ has joined #openstack-cinder04:00
avishayjgriffith: this does fix a bug.  cinder currently allows you to do something questionable, i agree.  however that behavior had a bug.04:01
*** dannywilson has joined #openstack-cinder04:01
avishayjgriffith: changing the API behavior is a bigger change to solve a different issue04:01
jgriffithavishay: hmm... I guess I"m still confused04:02
jgriffithavishay: so first, there's no way for this to work in most cases that I am aware of04:02
jgriffithavishay: but more importantly it seems you disagree with me, which means I need to rethink04:03
avishayjgriffith: it's a behavior that is questionable, i agree.  for it to work with dd, data would need to be flushed and no writes happening until the upload finishes.  that's crazy.04:03
jgriffithavishay: well, even without dd...04:04
avishayjgriffith: HOWEVER, given this crazy behavior, there is a bug :)04:04
jgriffithavishay: the problem is you can't multi-attach a volume04:04
jgriffithavishay: so even if it's not LVM, local whatever04:04
avishayjgriffith: wait, let me look at the test, which was the basis for your question04:04
jgriffithavishay: the point is you can't actually attach a volume twice04:04
jgriffithavishay: sorry... I should probably link the bug04:04
openstackLaunchpad bug 1406703 in Cinder kilo "Deleting VM with an attached volume during copy-volume-to-image causes the volume remains in-use state" [Medium,In progress]04:05
jgriffithavishay: and, I mean... "Yeah" it's in-use because it has to be attached to do an upload to Glance04:05
jgriffithduhhhh :)04:05
avishayjgriffith: so you're saying that the upload process is like an attachment, which should be illegal?04:05
avishayOK :)04:05
*** krtaylor has quit IRC04:06
jgriffithavishay: exactly... because the upload process IS an attach04:06
*** dannywilson has quit IRC04:06
jgriffithavishay: unless you're using some crazy thing like a converged storage thing that is both Glance and Block04:06
jgriffithand does it all internally04:06
avishayjgriffith: again, i agree that the API should be changed.  Maybe an exception could be made for those that do clone, but Cinder doesn't really do those exceptions.04:06
jgriffithavishay: ahh... yeah, I see what you're saying now too04:08
avishayjgriffith: yea we're agreeing :)04:08
jgriffithavishay: so yeah, that's the sticky point right04:08
jgriffithavishay: one-off exceptions create "problems" IMO04:08
jgriffithavishay: but yeah... we tend to agree in the end :)04:08
jgriffithavishay: BTW... how have you been?04:08
avishayjgriffith: i agree that when you have two backends and one supports the behavior and the other doesn't, the API behaves strangely04:09
avishayjgriffith: perhaps a config option that would be applied globally to all backends in the deployment - either you support volume->image for attached, or not - not per backend04:09
avishaydoing well, working on my "converged storage thing that is both Glance and Block" :P04:10
*** krtaylor has joined #openstack-cinder04:11
openstackgerritJohn Griffith proposed openstack/cinder: Revert "Get volume from db again before updating it's status"
*** patrickeast has joined #openstack-cinder04:15
avishayjgriffith: don't agree with the revert.  given the behavior that cinder allows, the patch fixes a bug.  the fact that the behavior shouldn't be allowed is a bigger issue.04:19
jgriffithavishay: yeah, I know nobody is going to agree with it :)04:19
jgriffithavishay: that's ok04:19
avishayjgriffith: but people are apparently doing this, so it should at least not mess up volume states04:20

rakesh_mishra_I just want to know if i create a snapshot of a volume then what will be the size of the snapshot in file system04:45
jgriffithrakesh_mishra_: what driver?04:46
jgriffithavishay: bahh04:51
jgriffithavishay: apparantly that _feature_ has been there *forever*04:51
avishayjgriffith: moo04:51
rakesh_mishra_LVM and ceph for both04:51
jgriffithrakesh_mishra_: so those are two different things for starters :)04:51
jgriffithLVM a snap takes no new space04:52
avishayjgriffith: sorry i saw "bahh" and thought we were doing animal noises04:52
jgriffithrakesh_mishra_: snaps are COW files04:52
avishayjgriffith: yes04:52
jgriffithavishay: LOL04:52
jgriffithavishay: now I get it!04:52
jgriffithsheep, cow04:52
avishayhaha :)04:52
jgriffithrakesh_mishra_: copy on write04:53
jgriffithrakesh_mishra_: and it's not "on the file system"04:53
jgriffithrakesh_mishra_: it's an LV carved out of the Volume Group04:53
jgriffithrakesh_mishra_: Ceph is a different beat04:53
jgriffithrakesh_mishra_: but they do similar things04:53
rakesh_mishra_jgriffith:  LV carved?04:54
jgriffithrakesh_mishra_: sounds like you might want to do some research on how all of this works before you worry about snapshots and filesystem allocation04:55
rakesh_mishra_jgriffith: if i create 5 snapshots of 50 GB volume then total available quota should decrease na?04:55
jgriffithrakesh_mishra_: You didn't ask about quota, you asked about filesystem04:56
jgriffithrakesh_mishra_: that's entirely different04:56

jgriffithrakesh_mishra: you're back :)04:59
jgriffithrakesh_mishra: so... what I was saying was04:59
jgriffithrakesh_mishra: quotas in Cinder are completely different04:59
jgriffithrakesh_mishra: and we have quotas for both snapshots and volumes04:59
jgriffithrakesh_mishra: those quotas are both "count" and "capacity"04:59
rakesh_mishrajgriffith: yes04:59
jgriffithrakesh_mishra: so there's "snapshot space in Gig", "volume space in Gig" and count fo rboth05:00
rakesh_mishraso when i create 5 GB of volume and create the snapshot then what should be the size of the snapshot , it just has a pointer to point volume or it copy full volume05:00
*** patrickeast has quit IRC05:01
jgriffithrakesh_mishra: the actual size of the snapshot is basically zero05:02
jgriffithrakesh_mishra: but the quota used is 5 GB05:02

rakesh_mishra__t copy full volume , so whenever i create the volume it decrease my total available quota but it does not do the same thing in case of snapshots05:27
jgriffithrakesh_mishra__: I don't know how else to say it, but to say it again:05:27

*** vilobhmm1 has joined #openstack-cinder15:58
hemnaso it's 3 different versions we poop out that are important15:58
jgriffithwell then add the third one to your driver :)15:59

hemnasure, but I still think it's a valuable thing for other drivers do have no ?15:59
jgriffithOr actually, I'll add it as part of that patch if you want15:59
hemnaI was just trying to be consistent for everyone when I added the init_host logging.15:59
jgriffithhemna: nah... I think it's noise.  But, I was hoping others would review15:59

xyang1hemna: Can you help review them?17:46
hemnaxyang1, ok I'll look them over :)17:46
xyang1hemna: Thanks!17:46
jungleboyjxyang1: I don't see the consistency group BP referenced.17:46
xyang1jungleboyj: It is there
eskerjgriffith: thx17:47
jgriffithesker: sure17:47
jungleboyjYes, but I can't find the actual BP.17:47
xyang1jungleboyj: That is not my fault, once api changes are merged, the link is wrong17:48
jungleboyjOh, it is because the cinder side changes already went in?17:48
xyang1jungleboyj: Yes17:49
xyang1jungleboyj: That is why I want the client side to be in kilo as well17:49
xyang1jungleboyj: Bp is still there, but the auto link is wrong after the bp is complete17:50
hemnaxyang1, do_consisgroup_update17:50
hemnathere is no output or for that one ?17:50
xyang1hemna: What do you mean?17:51
hemnaso when someone calls it from the cmdln what output do they see if it works?17:51

jgriffitheharney: LOL17:53
eharneyjgriffith: hmm?17:53
jgriffitheharney: I just went to log a bug for notification counts, launchpad informed me I was stupid and it's already logged... by me :)17:53
jgriffitheharney: but the good news is, it's assigned to you :)
openstackLaunchpad bug 1412513 in Cinder "Intermittent unit test failures for incorrect notifier count" [Undecided,Confirmed] - Assigned to Eric Harney (eharney)17:54
eharneyjgriffith: oh yeah... i haven't seen that one crop up much lately17:54
jgriffitheharney: I hadn't either, that's why I forgot about it... BUT17:54
jgriffitheharney: I've now hit it 4 or 5 times in the last 24 hours17:54
jgriffithbetween gate and local17:54
eharneyi've never managed to hit in in a local env17:54
jgriffitheharney: yeah, it's tricky... I can't make it repeat at all17:55
eharneyi also poked around in there and couldn't really ever find a probably source of the problem17:55
jgriffitheharney: only thing I'm noticing is that it does seem to always be in consistency group tests17:55
eharneyi think something is broken somewhere with our mocking/fake_notifier stuff where data from some tests maybe leaks into others... but i don't know where17:56
jgriffitheharney: I'll check if we have an ER and if not create one, so we can get more stats17:56
jgriffitheharney: yeah, sadly I think we have A LOT of that (leakage)17:56
eharneyjgriffith: i don't think there is one, but it should be easy to make one now17:56
jgriffitheharney: yeah, I'll see if I can't do that here shortly17:56

smcginnisjgriffith, jungleboyj: Just skimming through what I missed while away. Someone was just talking about block driver recently.18:14
smcginnisjgriffith, jungleboyj: DuncanT was involved in the conversation if I remember correct.18:14
jgriffithsmcginnis: cool18:15
smcginnisSOmeone is using it and has it for some special solution.18:15
jgriffithsmcginnis: Mirantis is the only one I know of18:15
jgriffithsmcginnis: they use it for hadoop service18:15
smcginnisjgriffith: It could quite possibly Mirantis. Wish I could remember who that was.18:15
smcginnisHadoop, that was it.18:15
jungleboyjsmcginnis: Ok.18:15
jgriffithMixed on whether that should've been left in or not, but not my biz18:15
smcginnisjgriffith: Apparently they test it internally a lot.18:15
jgriffithsmcginnis: they test it internally against *their* use case, not ours :)18:16
jgriffithsmcginnis: it's just a matter of time before a customer files a bug18:16
smcginnisjgriffith: Would that be considered one of the "open source solution" drivers that should be added to Jenkins? Kinda like sheepdog and ceph?18:16
jungleboyjsmcginnis: Seems like that should be made exnternally avaialable.18:16
smcginnisjungleboyj: I agree.18:16
jgriffithsmcginnis: yeah, but the real problem is it "can't" do Cinder things18:16
smcginnisjgriffith: Oh, true.18:17
jgriffithsmcginnis: in other words the test file would look kinda funny with all the skips in it ;)18:17
smcginnisIt's a limited driver, isn't it.18:17
jgriffithvery much so yes18:17
* smcginnis hasn't actually looked at the code.18:17
jgriffithsmcginnis: and I still argue on a regular basis that if you use a good dedicated 10G iSCSI network that's not typically the bottle-neck18:17
smcginnisjgriffith: I agree. Especially locally, iscsi shouldn't have _that_ much overhead.18:18
jgriffithnah.. I did a bunch of benchmarks on that a while back18:18
jgriffithnegligible diff between local, iscsi and FC18:18
jgriffithbut it does require a dedicated iSCSI network at least 10G with Jumbo Frames18:19
smcginnisI wonder if they've actually tried it and benchmarked for their solution.18:19
jgriffithsmcginnis: they said they did18:19
jgriffithanyway, not my problem :)18:19
smcginnisWell, it is always more difficult when you have to get the networking guys involved. :)18:19
jgriffithsmcginnis: ain't that the truth.. they're almost as bad as the Storage Folks18:19
