tommylikehuhey smcginnis, I found a etherpad which talks about cross project user nofications, do you happened to know the current situation of that idea?00:50
tommylikehuhttps://etherpad.openstack.org/p/liberty-cross-project-user-notifications00:50
smcginnistommylikehu: Hmm, no. I hadn't seen that one.00:51
tommylikehusmcginnis: ok, so you may never heard that we would have a individual project which focus on this kind of stuff?00:52
smcginnistommylikehu: No. Probably an idea someone had that never took off I'm guessing.00:53
smcginnistommylikehu: If you're interested in seeing if you can get something going, might be good to post on the mailing list and see if anyone has any background on it.00:54

isaacbxinli: Hi13:41
xinliisaacb: hi13:41
isaacbxinli: in https://review.openstack.org/448159 I'm trying to understand what are the implications of having a volume with type replication_enables on the driver functionality13:42
isaacbxinli: if the group is not a CG, does the driver need to do anything if there are volumes with type replication_enabled?13:44
xinliisaacb: to be honest with you, I am not familiar with XIV driver, I can't answer this Q. sorry for not help.13:47
isaacbxinli: Let me put it this way: if the group is not CG, then from the storage point of view, all the volumes in this group are not connected to each other. if one of the volumes is replicated, how the manager deals with it?13:50
smcginnisisaacb: Are you actually looking for xyang?13:51
xinliissaacb: if the group is not CG, then no need to synchronize them with each other, the other volumes in the pool should keep their original status. right?13:53

geguileoisaacb: nothing yet, sorry15:30
*** xyang has quit IRC15:30
geguileoisaacb: but the basic idea is that you need to review you current locks to see which ones need to be shared among all the nodes that share the backend15:31
geguileoisaacb: and change those to use the DLM15:31
geguileoisaacb: then you need to look for cases where you could get into trouble if 2 operations/actions could happen on different nodes15:31
geguileoisaacb: and also look into caching issues when data is different between the nodes15:32

isaacbxyang: ping17:40
xyangisaacb: hi17:41
isaacbxyang: Hi. question about VGS.17:41
isaacbxyang: if a group is not CG is it enough to raise NotImplementedError()17:42
xyangisaacb: for example, if you raise NotImplementedError() in create_group in your driver, it will be routed to call the default implementation, which is just a group of volumes but not supporting consistent group snapshot17:43
isaacbxyang: right. What if one of the volumes has type replication_enabled?17:44
xyangisaacb: in that case, your driver should handle it properly17:45
isaacbxyang: you mean for CG?17:45
xyangisaacb: no17:46
xyangisaacb: there's no replication group support in cinder yet.17:46
isaacbxyang: I know. but if deal with generic group, why this is not the responsibility of the manager?17:47
isaacbxyang: For example who checks this situation for drivers that don't implement create_group17:48
xyangisaacb: What exactly is the situation?  when you are in create_group in the driver, if the type does not have consistent_group_snapshot_enabled set to True?17:51
isaacbYes. and one of the volumes has the type replication_enabled17:52
isaacbxyang: ^17:52
*** links has joined #openstack-cinder17:52
xyangone of the volumes?  when you are in create_group(), it should be an empty group17:53
*** mvk has joined #openstack-cinder17:53
isaacbxyang: you right. I meant  update_group17:54
xyangisaacb: so you have a volume in add_volumes in update_group and that volume type has replication_enabled?17:55
isaacbxyang: yes. Is it enough to raise NotImplementedError() or the driver need to raise exception here?17:56

thingeeit's kind of hard to see the slide but basically everything is mashed into qos specs for volume type20:39
thingeeinstead of just using volume type specs20:39
jgriffiththingee what's that guy presenting on there?20:39
thingeejgriffith: basically a middle man implementation to both block/object storage.20:40
jgriffiththingee yeah, just curious which one20:40
thingeehttp://www.hedviginc.com/20:41
jgriffithOh!  Them20:41
jgriffithso I don't recall the conversation we had on this, but I don't see what he's doing that we don't typically do/recommend with Cinder20:41
jgriffithCreate a type... assign extra-specs.... create a qos-spec; assign qos-spec to the type20:42
thingeetheir key feature is they they're a proxy to any protocol.20:42
thingeewhich I was like .... ok...20:42
thingeeaside from replication stuff20:42
jgriffiththingee oh, yeah... that part20:42
jgriffithI got your point there20:43
thingeeI deploy FC storage backends, but oh no I don't have the right interfaces on my nodes so I need to have this go through another machine that has the right interface and provide it via iscsi20:44

mriedemif the scality volume driver isn't in cinder, i don't see why we even have the vendor driver in nova23:17
