#openstack-nova - 2017-09-26
07:45:41	gmann	bauzas: all the best :)
07:48:59	gibi	I feel your pain. I created a one slider for a local meetup.
07:50:04	openstackgerrit	jichenjc proposed openstack/nova-specs master: Adds spec for instance live resize https://review.openstack.org/141219
07:50:48	openstackgerrit	Takashi NATSUME proposed openstack/nova master: Fix test_get_volume_config method https://review.openstack.org/489467
07:56:02	bauzas	gibi: that's the problem when you say to your friends 'sure, I can talk about that'.
07:56:20	bauzas	then, you should know you're doomed for the whole week
07:59:34	gibi	bauzas: I decided to do it a bit blindly and only created a single slide. I will talk about what I will remember. Bit more stress during the talk lot less stress during the week before the talk :)
08:02:29	openstackgerrit	jichenjc proposed openstack/nova-specs master: Adds spec for instance live resize https://review.openstack.org/141219
08:02:40	bauzas	gibi: probably a good idea
08:02:47	bauzas	gibi: just some pointers and job done
08:03:02	bauzas	more interactive
08:03:19	bauzas	gibi: you saved my day, exactly like you saved our bugs
08:04:01	bauzas	you saved *from* our bugs :)
08:04:36	bauzas	unrelated, haven't seen yet the new zuul
08:08:19	gibi	at least the status page looks the same for zuul but I guess that means nothing
08:09:58	gibi	bauzas: do you have the link for melwitt's interview about what-happened-in-Pike-in-nova?
08:10:22	gibi	bauzas: I can even play that video on the meetup :)
08:11:03	bauzas	gibi: I can find it
08:11:20	bauzas	I wouldn't like to be talking alot of Nova
08:11:28	gibi	bauzas: here it is https://www.youtube.com/watch?v=d7vFqM3ZEdI
08:12:35	gibi	bauzas: ohh you have to cover the whole OpenStack? that scary
08:12:49	bauzas	:)

11:09:56	gibi	bauzas: could you make a quick look at https://review.openstack.org/#/c/504930/ ? it is a single line of test case improvement that removes an test instability.
11:14:00	openstackgerrit	Zhenyu Zheng proposed openstack/nova master: nova-manage db archive_deleted_rows is not multi-cell aware https://review.openstack.org/507486
11:21:16	openstackgerrit	Matthew Booth proposed openstack/nova master: libvirt: Don't VIR_MIGRATE_NON_SHARED_INC without migrate_disks https://review.openstack.org/507202
11:21:17	openstackgerrit	Matthew Booth proposed openstack/nova master: python3: Specify unicode explicitly calling etree.tostring() https://review.openstack.org/507488
11:22:15	mdbooth	stephenfin: You were looking at ^^^
11:22:59	mdbooth	There was a python3 problem in the first version of that patch. Turns out it's a general problem with etree.tostring() which other tests were ignoring by mocking out :/
11:23:23	mdbooth	Hence the prior patch to fix all etree.tostring() calls
11:33:45	mdbooth	gibi: Before I rebase it, any chance you could promote your +1 here to a +2: https://review.openstack.org/#/c/479802/8 ?
11:33:55	mdbooth	Then I'll rebase in a bit after it merges
11:37:46	openstackgerrit	Matthew Booth proposed openstack/nova master: Ensure errors_out_migration errors out migration https://review.openstack.org/479802
11:37:46	openstackgerrit	Matthew Booth proposed openstack/nova master: Use Migration object in ComputeManagerMigrationTestCase https://review.openstack.org/502126
11:37:47	openstackgerrit	Matthew Booth proposed openstack/nova master: Automatically revert resize which fails on destination https://review.openstack.org/462521
11:37:48	mdbooth	Actually meh it was a clean rebase anyway. Should keep the existing +2.
11:56:36	openstackgerrit	Lajos Katona proposed openstack/nova master: Extend ServerMovingTests with custom resources https://review.openstack.org/497399
12:13:04	openstackgerrit	Alex Xu proposed openstack/nova-specs master: Add trait support in the allocation candidates API https://review.openstack.org/497713
12:14:51	bauzas	gibi: sorry was outside, but back now, +W'd
12:16:21	gibi	bauzas: thanks
12:16:39	gibi	mdbooth: I'm on a meeting but opened the review so I will check it
12:17:02	efried	ratailor Did you get your questions answered about the osc microversion?
12:17:24	ratailor	efried, not yet. could you help ?
12:18:01	efried	ratailor Your observation is correct, and by design. As for the reasoning behind it... that's complicated.
12:18:42	efried	ratailor But if you want a specific microversion in osc, you can ask for it with an env var, CLI opt, or (I think) conf var.
12:19:13	bauzas	efried: if the microversion is not asking for a new attribute :p
12:19:27	efried	Yeah, there's that :)
12:19:37	mdbooth	efried: OSC will happily send invalid requests because it doesn't understand those microversions, though.
12:20:02	manasm	bauzas: running into an issue with resize on an upgraded env from Ocata to Pike, the resize fails at following call in scheduler_utils.setup_instance_group method -
12:20:04	mdbooth	At that point, the user might as well just open telnet and type the http themselves :)
12:20:07	efried	ratailor A lot of it has to do with the fact, as bauzas and mdbooth are pointing out, that osc has not maintained functional parity with microversions.
12:20:07	manasm	request_spec.instance_group.hosts = list(group_info.hosts)
12:20:49	manasm	bauzas: this is because the instance_group is set to None in the request_spec.
12:21:03	manasm	Is there a known issue around that?
12:21:04	bauzas	manasm: do you have an open bug for that?
12:21:14	manasm	not yet
12:21:18	ratailor	efried, To make it as stable as possible. right ?
12:21:30	ratailor	efried, and backward compatible.
12:21:49	efried	ratailor The reasoning may not be quite that high-minded :)
12:21:59	ratailor	efried, cool
12:22:07	mdbooth	This is a data corruptor with a simple fix: https://review.openstack.org/#/c/507202/
12:22:20	bauzas	manasm: AFAIR, we create a new InstanceGroup object when looking at the primitive dicts
12:22:40	ratailor	efried, Thanks!
12:22:56	efried	ratailor If you want more history/explanation on the osc side, find dtroyer. I don't remember offhand which channel is the accepted one for talking about the CLI, but I know he's in #openstack-dev
12:22:58	mdbooth	Affects libvirt live migration with attached volumes
12:23:25	efried	ratailor Possibly #openstack-sdks
12:23:52	ratailor	efried, sure, Thanks!
12:24:12	efried	ratailor yw, good luck.
12:24:19	ratailor	efried, actually I was searching him only, but didn't found in core openstack channels.
12:24:27	ratailor	efried, Thanks for your help!
12:24:52	efried	It may be a tad early for him to be on just yet, but he's at least got bouncers in those two channels.
12:25:10	manasm	bauzas: yes, we have the new InstanceGroup object but the we are trying to assign it to request_spec.instance_group which is None.
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.
