| 12:25:47 | bauzas | efried: ratailor: FWIW, I already provided a point for the Sydney Forum about OSC vs. our CLI in https://etherpad.openstack.org/p/SYD-nova-brainstorming L35 | |
| 12:26:08 | bauzas | I'd love to hear operators about what they use and how | |
| 12:27:29 | ratailor | bauzas, ++1 | |
| 12:28:06 | bauzas | manasm: you said when you resize? | |
| 12:28:16 | bauzas | manasm: so we're getting the ReqSpec from the DB first | |
| 12:28:53 | bauzas | if there was no group yet for that instance, then the ReqSpec.instance_group field could be None | |
| 12:28:55 | manasm | yes, btw we get the object from db using - objects.InstanceGroup.get_by_instance_uuid(context, instance_uuid), and if it is None then we don't hit the issue. | |
| 12:32:27 | bauzas | manasm: wait, I need to look at the code for resize | |
| 12:32:36 | bauzas | do you have a stacktrace to share? | |
| 12:38:52 | kashyap | mdbooth: FWIW, looks good. Compact summary, and a nice fix: https://review.openstack.org/#/c/507202/2 | |
| 12:39:56 | mdbooth | It breaks some tempest tests, though :/ | |
| 12:40:02 | mdbooth | Probably means I didn't think of something. | |
| 12:40:20 | mdbooth | It does look obvious, though. | |
| 12:40:26 | stephenfin | mdbooth: Reviewed both. Tidy job | |
| 12:40:45 | kashyap | mdbooth: Wonder if you want to link to to the virDomainMigrateFlags page: https://libvirt.org/html/libvirt-libvirt-domain.html#virDomainMigrateFlags | |
| 12:40:58 | kashyap | Which talks about WTF actually the flag VIR_MIGRATE_NON_SHARED_INC is | |
| 12:41:07 | kashyap | If you think it's not needed, disregard me | |
| 12:42:30 | kashyap | Maybe not required. Those who want to know about it, a simple look up will fetch it | |
| 12:44:40 | kashyap | BTW, the "tempest-dsvm-full-xenial" succeeded | |
| 12:51:23 | kashyap | Ah, it's the "gate-grenade-dsvm-neutron-ubuntu-xenial" that failed. | |
| 12:52:03 | mdbooth | kashyap: Yep, in the block migration tests :) | |
| 12:52:13 | mdbooth | I suspect the failure there is probably related ;) | |
| 12:52:44 | mdbooth | kashyap: If you have time to investigate those failures, btw, I have to do something else right now. Otherwise I'll get to them later. | |
| 12:52:53 | kashyap | mdbooth: I'm looking at the log - http://logs.openstack.org/02/507202/2/check/gate-tempest-dsvm-py35-ubuntu-xenial/8485b63/console.html | |
| 12:53:10 | kashyap | I'll note on the review if I learn something new from the log | |
| 12:53:56 | openstackgerrit | Yikun Jiang proposed openstack/nova master: Update Instance action's updated_at when action event updated. https://review.openstack.org/507473 | |
| 12:54:51 | kashyap | So the right log is - http://logs.openstack.org/02/507202/2/check/gate-grenade-dsvm-neutron-multinode-live-migration-nv/b210147/console.html | |

| 13:16:40 | sdague | gibi: so, interesting fact from this morning, I'm pretty convinced we don't need any of the REQUIRES_LOCKING code | |
| 13:20:47 | sdague | gibi: also, if you are able to take a look at the qemu 2.10 support patch, that would be cool - https://review.openstack.org/#/c/505673/ | |
| 13:20:53 | sdague | or bauzas | |
| 13:23:43 | bauzas | ack | |
| 13:36:22 | mdbooth | stephenfin: Eurgh. So it seems that in python2.7 libvirt binding's migrateToURI3() barfs if destination_xml is unicode. | |
| 13:38:55 | mdbooth | stephenfin: think I'm going to leave that etree.tostring() patch always producing unicode, but I'm going to add a 2/3 hack next to the migrateToURI3 which handles the difference, because IMHO the libvirt bindings should accept a unicode string there, and it's just saner. | |
| 13:39:03 | kashyap | Matt, hmm, the assertThat() mismatch seems to be related to ID: | |
| 13:39:04 | kashyap | 2017-09-26 12:26:17.199293 | 2017-09-26 12:26:17.198 | reference = u'ubuntu-xenial-2-node-rax-ord-11137317-923993' | |
| 13:39:07 | kashyap | 2017-09-26 12:26:17.200739 | 2017-09-26 12:26:17.200 | actual = u'ubuntu-xenial-2-node-rax-ord-11137317' | |
| 13:39:19 | mdbooth | kashyap: Yes, that's just asserting that the migration happened | |
| 13:39:28 | mdbooth | i.e. assert id == the destination | |
| 13:40:00 | mdbooth | I hate python3 | |
| 13:40:15 | mdbooth | And python2 | |
| 13:40:28 | mdbooth | But the 2->3 split especially | |
| 13:40:49 | kashyap | Ah, I see. (about the assert ID) | |
| 13:49:02 | openstackgerrit | Ed Leafe proposed openstack/nova master: Add Selection objects https://review.openstack.org/499239 | |
| 13:51:32 | sdague | mriedem: I was diving through thinking more about https://review.openstack.org/#/c/507239/ last night, why do you think that external locking is required there? Because it should blow up if not provided but is needed | |
| 13:52:21 | mriedem | sdague: i thought that also locked those tests to run serially | |
| 13:52:26 | mriedem | maybe i should be using https://github.com/openstack/oslo.concurrency/blob/master/oslo_concurrency/fixture/lockutils.py#L22 | |
| 13:52:32 | mriedem | ^ is actually what i started using | |
| 13:52:36 | sdague | mriedem: serial to what? | |
| 13:52:49 | openstackgerrit | konstantin proposed openstack/nova master: switch from filesystem to disk for parallels containers https://review.openstack.org/506687 | |
| 13:52:49 | openstackgerrit | konstantin proposed openstack/nova master: don't add device address if there is no any units https://review.openstack.org/506686 | |
| 13:53:11 | mriedem | sdague: to other tests | |
| 13:53:26 | mriedem | like, things that would be mocking those nova.rpc globals | |
| 13:53:42 | sdague | all the tests in a worker run serially | |
| 13:53:50 | sdague | and the tests between workers are in completely different processes | |
| 13:54:00 | sdague | with no shared state | |
| 13:54:42 | eantyshev | mikal: Hello! Regarding your review https://review.openstack.org/#/c/492325 | |
| 13:54:57 | sdague | The reason we had REQUIRES_LOCKING at all was because oslo required a directory name or it exploded | |
| 13:55:22 | sdague | but we feed those all temp directories anyway, they never cross lock between workers | |
| 13:56:33 | eantyshev | it fails on parallels virt_type, and I'd like to update it for you, don't you mind? | |
| 13:56:34 | sdague | but I actually don't think that default behavior holds any more, and we can probably fully delete that variable anyway, as it definitely confuses people as to what it does | |
| 13:56:54 | sdague | mriedem: https://review.openstack.org/#/c/507253/ - I was experimenting this morning | |
| 13:59:57 | mriedem | avolkov: you might like to take a crack at this https://bugs.launchpad.net/nova/+bug/1719460 | |
| 13:59:58 | openstack | Launchpad bug 1719460 in OpenStack Compute (nova) "(perf) Unnecessarily joining instance.services when listing instances regardless of microversion" [Medium,Triaged] | |
| 13:59:59 | mriedem | should be pretty simple | |
| 14:03:06 | dansmith | mriedem: any outcome from your testing yesterday? | |
| 14:03:43 | mriedem | dansmith: i've got the clean slate, just getting setup to start the 2nd scenario with the 500 ACTIVE and 500 ERROR instances | |
| 14:03:49 | mriedem | for the cell0 and cell1 listing | |
| 14:03:55 | dansmith | okay | |
| 14:04:11 | mriedem | going to need to do that flavor thing because otherwise it's a 60 second rpc timeout per call to select_destinations | |
| 14:04:27 | dansmith | yeah | |
| 14:06:53 | gibi | mriedem, sdague: this also means that the problems we see with the rpc tests in bug 1685333 is not beacuase of the lack of locking | |
| 14:06:54 | openstack | bug 1685333 in OpenStack Compute (nova) "Fatal Python error: Cannot recover from stack overflow. - in py35 unit test job" [High,Confirmed] https://launchpad.net/bugs/1685333 | |
| 14:06:54 | sdague | mriedem: is there a reset on rpc variables that is needed that's not happening? | |
| 14:07:19 | mriedem | sdague: the TestRPC class does a reset per test method | |
| 14:07:39 | sdague | gibi: I don't see how it could be. It might be a deadlock | |
| 14:07:48 | mriedem | dansmith: also came across this last night https://bugs.launchpad.net/nova/+bug/1719487 | |
| 14:07:50 | openstack | Launchpad bug 1719487 in OpenStack Compute (nova) "nova-manage db archive_deleted_rows is not multi-cell aware" [Wishlist,Triaged] - Assigned to Zhenyu Zheng (zhengzhenyu) | |
| 14:07:57 | sdague | the biggest issue though is it doesn't have the timeout bits in place, so it's hard to see what's going on | |
| 14:08:10 | sdague | I think if we trigger the timeout we get a stack trace | |
| 14:08:18 | gibi | sdague: that would be nice | |
| 14:08:22 | dansmith | mriedem: meh | |
| 14:08:50 | mriedem | meh?! | |
| 14:08:55 | mriedem | it's wishlist, sure | |
| 14:09:02 | dansmith | MEH | |
| 14:09:05 | mriedem | gdi | |
| 14:09:13 | gibi | sdague, mriedem: we are at the start of the cycle so I'm brave enough to try to remove the whole locking code and see what happens | |
