chenyingHi I have a question about the filed disable of object services. Does it only mark the status of a service enable/disable? What's the use?  when the service is up, it still can respond to user requests.07:53

dulekchenying: It's just used by scheduler - disabled cinder-volume won't accept new volumes.08:02
dulekchenying: It will however still respond to other requests - like deleting a volume.08:02
chenyingdulek: I see. I do a test just now.  I modified the stauts of a scheduler service 'disable = true' in cinder db. But a volume still can be created.08:08

swamireddyIs cinder supports multiple storage backends like lvm + ceph at the same time? mean I want to give a  few users lvm access and a few users ceph access?11:18
swamireddye0ne: Hi11:18
e0neyes, it does11:18
e0neyou can configure several backends for each cinder-volume11:19

e0nedulek: thanks for the links11:21
e0nedulek: you google faster than me11:22
duleke0ne: Here to help. ;)11:22
swamireddye0ne: dulek: Thank you very much. I am planning to use the 3 back-ends11:22
*** gcb has quit IRC11:23
swamireddye0ne: dulek: like ceph, lvm and 3rd party cluster. And set the storage cluster access based on the users. For ex: user1 to user10 - ceph, user11-user20 - lvm and user21-user30 - 3rd party cluster11:25
dulekswamireddy: You should be able to do that using multi backend, 3 volume types and granting permissions for different VTs to different users.11:27

diablo_rojosmcginnis: Good to know.14:38
e0nesmcginnis: do we plan to cut new python-cinderlient version before M-3?14:41
smcginnise0ne: Is there something in there we need to get out?14:42
smcginnisI would imagine we probably would by m-3 though.14:42
e0nesmcginnis: nothing that I know about it14:42
*** dslev has joined #openstack-cinder14:42
smcginnise0ne: If it's nothing critical for now, I think we probably wait until M-3, then do a final M release to get any bug fixes, etc. out.14:43
e0neI've got one patch to it and just want to get it in in a next release wherever it will be14:43
* smcginnis would check what's merged if gerritt worked :/14:43
e0neM-3 is a final deadline for clients14:44
*** baumann has joined #openstack-cinder14:44
smcginnise0ne: Yep. So if we cut a release immediately after M-3 there shouldn't be any other changes for M.14:46

bardiaasselin__: patrickeast and smcginnis suggest it might be the nodepool image and after I checked the nodepool image rebuilds had been failing and the image was still the original image which I suspect to be the cause of test failures21:21
asselin__bardia, still...you're the first confirmed person that I know of (other than me) that got it working!21:21

aorourkemudassirlatif, patrickeast ping22:36
patrickeastaorourke: pong22:37
aorourkepatrickeast, I have a question, I see Pure's implementation of v2 replication is unmanaged only and it is dependent on the patch that would allow recovering replicated volumes. Do you plan to support fail-back eventually?22:37
*** IlyaG has quit IRC22:38
patrickeastaorourke: with that patch to recover the replicated ones, yea22:38
patrickeastiirc we can flip back and forth between them with22:39
patrickeastwith both of those patches22:39
aorourkepatrickeast, Have you thought about how to deal with things such as someone creating a snapshot after a fail-over, so on the secondary array, then failing back? Anything cinder then does to those snapshots will not exist back on the primary array. Same goes for creating from snapshot, managing snapshots, etc.22:39
patrickeastaorourke: heh yea, i was chatting with hemna about this a bit yesterday22:39
aorourkepatrickeast, oh i must have missed that conversation :p22:39
patrickeastaorourke: basically by configuring our cinder driver for replication the driver is now managing multiple arrays22:39
aorourkeI will check scrollback22:40
patrickeastaorourke: so we can handle snapshots/volumes mixed across any of the configured replication targets22:40
patrickeastaorourke: iirc there are some issues with snapshots due to not having a provider_location or something though22:40
patrickeastwhich i'm not sure we have a great solution for atm22:40
patrickeastmudassirlatif: ^ that line up with whats actually going on?22:41
* patrickeast is still catching up a bit on where our impl is at22:41
*** IlyaG has joined #openstack-cinder22:41
aorourkeI see. so you are basically maintaining where these snapshots/volumes are located and going to that array. so if a snapshot was created after a fail-over, and you fail-back, anything done to that snapshot will still go to the array it was created on22:42
patrickeastyea22:43
aorourkeah, ok22:43
patrickeastaorourke: imo its pretty loosey goosey and we are probably going to get burned... but for now thats how the v2 replication works22:43
*** jdurgin has joined #openstack-cinder22:44
patrickeastaorourke: then for managed arrays we end up basically doing the same thing22:44
patrickeastaorourke: the code isnt up for review yet, but basically either cinder driver can manage the other ones array22:45
mudassirlatifpatrickeast: aorourke: yes, with the patch we are able to flip back and forth, we still need to figure out how to handle the “orphaned snapshots”22:45
aorourkeyeah, starting to look at that as well . fun fun fun22:47

sbezverkHello, quick question about a volume migration. Is it normal that cinder migrate from backend2 to backend3 cinder tries to allocate space in backend1 which is the default backend?23:26
sbezverkand not creating new volume in backend3 and then copying data..23:26
