mdihhi there, if using ceph as the storage cluster for cinder, would there be a flag or option to freeup unused blocks? seems like fstrim doesn't work07:10
*** rcernin has quit IRC07:11
mdihoh okay, found a link sorry for my previous question. seems like discard support has not been supported in cinder yet. or at least as of 2015. but is it supported now?07:45
mdihugh, nevermind, okay it has been supported already, at least in mitaka..sorry for my question hehe..thanks07:52

tommylikehuhey geguileo, do you mind to share the discussion and next step for the placement stuff for cinder?08:25
tommylikehuthere should be a topic on Friday with Nova guy, but I didn't get a chance for that:)08:27
geguileotommylikehu: Hi, we had a summary session on the Cinder room at some point, I think it's summarized there08:40
geguileotommylikehu: but there was no Friday meeting in the end08:40
geguileotommylikehu: Jay was going to write an email explaining what they did08:40
geguileoI'm still checking emails, so I don't know if he sent it or not08:40
tommylikehugeguileo:  ok, thanks, let's check jungleboyj's email:)08:41
geguileotommylikehu: The email will be from Jay Pipes08:47
tommylikehugeguileo: ooh, misunderstood:), so basically you will handle this in Stein?08:48

jungleboyjtommylikehu: and geguileo  I had a chat with Jay Pipes after the Crosss Project session and answered a number of questions.  I am thinking he got the info he needed then and that is why we didn't have the follow up meeting.12:11
jungleboyjtommylikehu: geguileo  Basically he is proposing that we set up a field in the database to increment a generation per pool and keep the pool information there.  When an update comes in, if it changes the pool information changes then the generation is updated.12:12
jungleboyjtommylikehu: geguileo  If the generation changes between when the data is looked up and when the process tries to save data then the scheduler will have to get the latest information and make the scheduler request again.12:14
geguileojungleboyj: oh, is that all???  then it's something similar to what I do with the workers table iirc12:14
jungleboyjgeguileo:  Yeah, it really didn't sound that bad from what he said.12:15
jungleboyjgeguileo:  I would watch for an e-mail from him to make sure I am right or send something out as follow up.12:15
geguileojungleboyj: I'll try to find the code in the placement project and see if I understand it12:15
jungleboyjIt sounded like he was still planning to send it.12:15
geguileojungleboyj: great  :-)12:15
jungleboyjgeguileo:  :-)  Let me know if there is anything else I can do to help.12:16

smcginnisjungleboyj: I'm going to send something to the ML asking infra to delete the driverfixes/ocata branch now that we can use stable/ocata.14:48
smcginnisjungleboyj: Any objection to doing that now?14:48
jungleboyjsmcginnis:  No, that is a good idea.  Avoid confusion there.14:49
smcginnisWe synced all patches, so I want to make sure we don't accidentally push something into driverfixes when it should go to stable.14:49
smcginnisjungleboyj: Cool, thanks.14:49
jungleboyjYeah.  Thank you for working on making that all happen.14:49

jungleboyjgeguileo: or jbernard  Since Eric is out do you guys know anything about Andreas' question about this failing from last night?
smcginnisThat's been failing for some time. I think eharney was looking into it, but I don't know the current status or if anything was found.17:52
jungleboyjsmcginnis:  Ok.  If it has been failing for a while it can wait until Eric gets back.17:52
smcginnisStill would be good to have it working. ;)17:53
geguileojungleboyj: I think this is the Swift credentials issue Eric mentioned on the PTG...17:53
smcginnisAh, that sounds familiar.17:53
smcginnisI think Eric might have been looking at a devstack change to fix this.17:53
jungleboyjHmmm, don't remember that one.17:54
jungleboyjsmcginnis:  Oh, I do remember him saying something about needing to change devstack.17:54
*** david-lyle has joined #openstack-cinder17:54
geguileoLooks like a credentials issue17:54
geguileoHe was thinking about looking into it17:55
geguileoor he was trying to get me curious enough about it to have a look17:55
geguileoone or the other   XD17:55
jungleboyjHe he he.17:55
smcginnisIIRC, admin credentials are set up, but this doesn't call swift as admin. Something along those lines.17:56

imacdonnanyone else able to access this?
imacdonnI can get Wednesday and Friday, but not Thursday :/20:51
smcginnisStuck on "Loading..." for me.20:51
imacdonnyeah, that's what I'm getting20:51
smcginnisMust be everyone doing their PTG recaps. ;)20:51
imacdonnI was looking for the discussion about cascading deletes20:52
imacdonnwas that Thurs ?20:52
smcginnisI missed the morning, so maybe it was then.20:52
imacdonnI think you were there (or at least here)20:53
imacdonntalking about deleting a snapshot that has dependent child volumes20:53
smcginnisI don't recall that being discussed again. I thought we took care of that a cycle or two ago.20:53
smcginnisYeah, I think I was there. :)20:54
smcginnisThat some drivers need to internally do a clone instead so that the snapshot can actually be deleted before its dependent volume.20:55
smcginnisNow I remember.20:55
imacdonnI was thinking "one of us must be losing it" :)20:55
smcginnisThat would be me. ;)20:55
imacdonnso yeah ... I was reviewing the skipping of tests for ZFSSA CI (as promised)20:55
imacdonnI believe I'm down to two, and they're both due to that issue20:55
smcginnisI'm really not sure how we should proceed on that.20:55
smcginnisIt's an incredible speed advantage for many backends that creating a volume from a snapshot is almost instantaneous,20:56
smcginnisWhile creating a clone will be a much longer operation.20:56
imacdonnyes ... that's one of our main reasons for booting from volume at all20:56
smcginnisYeah, that's a big one. I know when I worked on Dell SC, boot from cached image was really quick because of the ability to just instantly have a boot volume.20:57
imacdonnright ... combined with our obnoxiously large images ("our" => my day job), it makes a big difference20:58
smcginnisI think I may have had some experience with your obnoxiously large images. ;)21:03
*** raunakkumar has joined #openstack-cinder21:04
*** prashkre has quit IRC21:06
imacdonnhmmm ok :)21:06
imacdonnso yeah, we'll have to figure out what to do about that .. meanwhile I'll have at least these two tests disabled21:09
imacdonnthis is the obvious one: tempest.api.volume.test_volume_delete_cascade.VolumesDeleteCascade.test_volume_from_snapshot_cascade_delete21:10
imacdonnthis one also fails: tempest.scenario.test_volume_boot_pattern.TestVolumeBootPattern.test_create_server_from_volume_snapshot21:10
imacdonnit appears that it's trying to delete the snapshot before nova is done deleting the child volume21:10
smcginnisThat last one might require an update to the tempest test to actually wait for the deletion to finish. There have been other cases of that.21:12
imacdonnyeah. I'm not sure where the deletion is happening, actually ... it must be some sort of automatic cleanup21:12
imacdonntest is
imacdonnbut it doesn't explicitly delete anything (AFAICT)21:14
smcginnisYeah, probably in the cleanup handling.21:14
