04:17:03	openstackgerrit	Zhang Hua proposed openstack/nova master: Try our best to bypass the dirty BDM to make nova more robust https://review.openstack.org/453451

04:43:37	MarkMielke	Any Block Device Mapping experts online?
04:48:43	MarkMielke	I'm having a bit of trouble understanding how to get the root_gb for bdm with destination_type = 'local', boot_index = 0. It doesn't seem to be recorded any more. volume_size is None.
04:49:22	MarkMielke	I thought no worries - the flavor should work, right? Well, we have instances with local root, even though the flavor specifies root_gb = 0. Probably, it was changed at some point.

11:19:00	johnthetubaguy	bauzas: cdent: are you folks OK with this one by any chance? https://review.openstack.org/#/c/453030
11:19:44	cdent	johnthetubaguy: i'm not up to date with the changes since my comments since ps1, but in principle, yes
11:23:11	johnthetubaguy	cdent: OK, cool, I just didn't feel I should +W without more placement experts feeling happy with it
11:23:32	cdent	I'm doing a re-review now just to be sure
11:28:13	cdent	johnthetubaguy: had some minor suggestions, but I think they could be followups

11:56:12	yasemin_	hi, i installed stable/ocata , multinode devstack and when i add compute node, it gives an error like Failed to perform requested operation on instance "demo", the instance has an error status: Please try again later [Error: Host 'compute-1' is not mapped to any cell].
11:56:19	yasemin_	can you help me ?
12:01:54	artom	yasemin_, I think you need to run nova-manage cell_v2 discover_hosts
12:03:03	yasemin_	artom, how can i run it ?
12:03:29	artom	yasemin_, from the command line on the controller node
12:10:02	yasemin_	atom, how is the command ? or can you suggest any doc ?
12:16:16	artom	yasemin_, the command is 'nova-manage cell_v2 discover_hosts' :)
12:16:26	frickler	yasemin_: https://docs.openstack.org/developer/nova/cells.html#setup-of-cells-v2
12:17:13	artom	frickler, I think his issue is that he added a compute, and the compute isn't mapped to a cell
12:18:30	yasemin_	artom, :) sorry
12:18:50	yasemin_	result = self._query(quer
12:18:50	yasemin_	/usr/local/lib/python2.7/dist-packages/pymysql/cursors.py:166: Warning: (3090, u"Changing sql mode 'NO_AUTO_CREATE_USER' is deprecated. It will be removed in a future release.")
12:19:03	frickler	artom: yes, and the step you mention is correct, I was just adding the doc component for it
12:19:10	artom	I'm pretty sure there are plans to run discover_hosts automatically, either in a periodic task, or upon manual compute node addition, but those haven't materialized yet, so it has to be run manually
12:20:19	frickler	artom: one can enable it with this I think: https://review.openstack.org/#/c/453004/1/doc/install-guide/source/nova-compute-install.rst
12:20:34	yasemin_	i think , it should be automatically :)
12:24:05	openstackgerrit	Ghanshyam Mann proposed openstack/nova master: Use plain routes list for '/servers' endpoint instead of stevedore https://review.openstack.org/445864
12:35:42	markus_z	oomichi: Please have a look at https://review.openstack.org/#/c/453220/
12:40:04	efried	sdague Remember that thing the other day where threading was killinme and you pointed me to recent eventlet changes?
12:40:30	efried	sdague https://review.openstack.org/#/c/453301/ is part of the solution. You're a requirements bigwig, right?
12:40:37	efried	Would you mind having a look?
12:46:19	jaypipes	jianghuaw_: morning (or evening) :)
12:46:38	jaypipes	jianghuaw_: so I've been wondering about something in the VGPU spec...
12:46:44	sdague	efried: +2
12:46:53	efried	sdague Thank you sir.
12:46:59	jaypipes	are you and Bob Ball available for a Google hangout this morning to discuss a couple things?
12:51:38	gmann	Nova API meeting in 10 min on #openstack-meeting-4
12:54:06	markus_z	alex_xu: Please have a look at https://review.openstack.org/#/c/453220/
12:58:19	jaypipes	mdbooth: "searchlight should load it from nova" <-- hmm, pretty sure Searchlight isn't going to want to do that :)
12:58:30	jaypipes	mdbooth: though I agree with your general statement.
12:58:37	jaypipes	about long-term maintenance of the code.
12:59:09	mdbooth	jaypipes: I briefly poked around in searchlight's nova plugin, and it contains a bunch of assumptions about state transitions
12:59:24	mdbooth	Things which we don't even do a good job of following just within compute manager
12:59:25	jaypipes	mdbooth: like I said, I agree with your general statement :)
12:59:51	jaypipes	mdbooth: I'm just saying I don't believe searchlight will want to make a dependency on any nova Python package.
12:59:56	mdbooth	Duplicating in a proverbial locked cabinet behind a door marked 'beware of the leopard' seems unwise
13:00:16	jaypipes	mdbooth: unless we created a different wheel entirely for this, housed in the nova source tree, but packaged separately.
13:00:25	openstackgerrit	Balazs Gibizer proposed openstack/nova master: Add snapshot id to the snapshot notifications https://review.openstack.org/453077
13:00:37	mdbooth	jaypipes: Right, I wasn't really suggesting that. More that if they defined a plugin api, they could just load a bunch of plugins
13:00:50	jaypipes	ya
13:00:52	mdbooth	And the nova plugin would be part of nova
13:00:55	jaypipes	totally makes sense.
13:01:01	mriedem	searchlight wouldn't import nova, it would load a stevedore extension right?
13:01:11	mriedem	all runtime shenanigans
13:01:22	mdbooth	mriedem: Yeah, totally at runtime
