-openstackstatus- NOTICE: Jobs using devstack-gate (legacy devstack jobs) have been failing due to an ara update. We use now a newer ansible version, it's safe to recheck if you see "ImportError: No module named manager" in the logs.09:57

fried_riceedmondsw: That log message is a red herring. If you look right after, it recovers.20:13
edmondswok, good20:14
edmondswso something else going on. You still looking?20:14
edmondswI haven't had a chance to even pull the logs up20:14
fried_riceedmondsw: I'm... multitasking. Which I patently suck at. But yeah, it's somewhere in my swap space.20:19
edmondswfried_rice thanks20:20
fried_riceedmondsw: Um, there's something very wrong here, though. The compute log is way too short to have handled the passing tests.20:21
fried_riceunless none of the 700-odd of the passing tests actually touch the compute service.20:22
fried_riceWhich would beg the question: why do we need them in our CI?20:22
edmondswyeah...20:22
edmondswwe really need to do a scrub of what we test and don't test in CI20:23
fried_ricewell that's easy.20:23
edmondswI don't mean just determining what we test and don't test, but rather figuring out where we test things we shouldn't or don't test things we should and changing accordingly20:24

openstackgerritEric Fried proposed openstack/nova-powervm master: DNM: See what in the CI doesn't need our code  https://review.openstack.org/59906620:30
fried_riceedmondsw: Assuming the compute service will still start, we ought to be able to remove any tests that still pass this ^20:31
fried_rice(well, we *certainly* ought to be able to remove tests that pass if the compute service *doesn't* start...)20:31
fried_riceI guess technically I ought to do the same thing to networking-powervm and ceilometer-powervm.20:32
fried_riceBut I don't seriously expect us to take action on this; just playing around.20:32

fried_riceedmondsw: All the allocation candidate requests are coming back empty. No way to tell at this point without going in and looking at an actual system, but this may be because the allocation ratios are getting zeroed out.20:37
fried_riceedmondsw: How frequent is the failure?20:37
*** openstackstatus has joined #openstack-powervm20:38
fried_riceI'm suspecting https://bugs.launchpad.net/nova/+bug/1789654 btw20:38
openstackLaunchpad bug 1789654 in OpenStack Compute (nova) "placement allocation_ratio initialized with 0.0" [High,In progress] - Assigned to Matt Riedemann (mriedem)20:38
*** ChanServ sets mode: +v openstackstatus20:38
edmondswfried_rice I think esberglu said 90%20:38
fried_riceedmondsw: Well, https://review.openstack.org/#/c/598365/ is the fix. And the fact that it passed our CI is a good sign. I'll recheck that bad boy a time or two and see.20:39
edmondswfried_rice thanks20:45
fried_riceedmondsw: I may have a way to confirm that that's the/a problem. Matt put up a couple of patches with additional debug logs. If we failed CI on those, the logs will tell us if this is the problem. I'm looking now...20:46
fried_riceedmondsw: Bingo: http://184.172.12.213/60/597560/6/check/nova-in-tree-pvm/9b7c798/logs/n-cpu.txt.gz#_Aug_30_16_43_09_41274820:48
fried_riceoo, that highlight is distracting.20:48

edmondswyep, good catch20:49
