fanzhangamrith, are you there ?01:46
fanzhangamrith, the bug number is right. I have updated the bug description. As for .gitignore, is there anything wrong for ignoring .idea directory while do commiting?01:50

amoralejamrith, would it be possible to release a new version of troveclient with https://review.openstack.org/#/c/487417/ before freeze?10:10
amoralejunit tests are failing with 2.11.010:11
amrithamoralej sure thing10:51
amrithwill do it right now10:51
amoralejamrith, thanks!10:51
amrithamoralej I just checked the queue and there's one more change I'd squeeze in if I could10:54
amriththat is this one10:54
amrithhttps://review.openstack.org/48201810:54
amrithit will be a little over an hour before the change merges10:54
amrithInstead of releasing two today, I'll just wait for that one if it is OK with you10:55
amoralejamrith, sure, i can wait10:55
amriththx amoralej I don't think the release team is awake yet :)10:57
amoralejyeah :)10:57

smatzekamrith, the gate-trove-scenario-dsvm-mysql-multi-ubuntu-xenial gate has been failing "Wait for non-affinity replica to fail." a lot in the past few days.  Is this a common sporadic failure point for the gate?15:38
smatzekI spent hours digging into this yesterday, to the point of looking at the implementation of the Nova anti-affinity filter to see exactly how its checking for anti-affinity.15:40
*** itlinux has joined #openstack-trove15:40
smatzekdespite the test case attempting to make a replica of an anti-affinity master with only 1 host, Nova is allowing the replica to be scheduled and become active.  The nova scheduler filter is getting an empty list for the list of hosts in the anti-affinity group.15:41
amrithit is periodic, happens more when the CI is under stress15:42
*** itlinux has quit IRC15:48
smatzekhave you looked into it much, are you thinking it's some Nova race condition, or something in Trove that could be touched up?  i.e. Trove sporadically not passing the Nova server group info correctly?15:48
smatzekif I can get time today between my teleconferences I'm thinking of tossing up a DNM/WIP review to add some more logging in this area to get more hints to root cause15:50
amrithsmatzek, I have. the issue is that trove's gate job spawns many VM's simultaneously and is not deterministic. Under load some tests, and some cleanups take a long time and therefore not having any hosts is a possible outcome. Under no load conditions (say Saturday morning eastern time) your job will pass fine but close to a release milestone, this is always a problem.15:50
amrithsmatzek go for it, have fun15:50
*** harlowja has quit IRC15:51
smatzeksince you're here atm, there is a fix up for review to unwedge one of the gates that Trevor and I worked on yesterday. ^  It's currently failing verify on the anti-affinity failure though.15:52

smatzekamrith, for what its worth, the anti-affinity gate test that keeps failing at load appears to be an issue in Nova, but there is insufficient logging to prove it at this point. In the Trove logs I can see that Trove is creating the anti-affinity master VM with a servergroup, the server group exists. It then waits for it to finish.18:32
amrithyes :)18:33
smatzekabout 2 minutes later the replica is created and the servergroup is correctly passed (based on novaclient's curl debug output in trove log). During scheduling of the replica, Nova's filter does a call to get the hosts of all instances in the server group to ensure it doesn't schedule on those, and gets an empty list.18:33
amrithbeen there, done that, have the t-shirt ... have also turned up logging and and debugged much further.18:33
smatzeknot Trove's problem.18:33
amrithno, it is Trove's problem18:34
amrithbut, ... if you think it isn't please do escalate it as a problem with Nova.18:34
smatzekfor the record, these types of issues bug me, which gives me the drive to keep going on them....18:34
amrithLike I said earlier, go for it, have fun.18:35
amrithwell, for the record, have fun18:35
smatzekif Trove is correctly passing the servergroup on all cases and there is a 2 minute gap between master and slave/replica creation and Nova still doesn't have record of the master's membership in the group, seems to be some problem in Nova.18:35
smatzekany tips on how to inject more logging into Nova while in Trove's gate ? :)18:36
smatzekbtw, can I get one of those t-shirts too ???18:37
smatzekor get a dump of DB table contents?18:39
