#openstack-nova - 2018-06-08
21:11:27	jroll	I'm just going to reopen https://bugs.launchpad.net/nova/+bug/1749167, looks to be the same
21:11:28	openstack	Launchpad bug 1749167 in OpenStack Compute (nova) "nova show can not get an instance information, and this instance can be queried from nova list." [Undecided,Expired]
21:12:51	melwitt	is it? this bug says they can see the instance with 'nova list' but can't delete it
21:13:05	melwitt	your paste shows a failure to 'nova list' at all
21:16:18	jroll	oh, good point
21:16:24	jroll	ok, I'll open anew
21:19:56	melwitt	if the 'nova list' involves deleted instances too, then the bug you linked earlier about lazy-load read_deleted="yes" may well fix your problem
21:20:39	melwitt	I guess that would only make sense if you did 'nova list --deleted'
21:21:01	jroll	https://bugs.launchpad.net/nova/+bug/1775934
21:21:02	openstack	Launchpad bug 1775934 in OpenStack Compute (nova) "Cannot run "openstack server list" with instance stuck in scheduling state" [Undecided,New]
21:21:05	jroll	yeah, this isn't with deleted
21:21:31	jroll	writing that I now understand why bauzus was trying to figure out how it got in that state
21:21:31	melwitt	k, thanks
21:21:42	jroll	I guess we probably don't expect it to work with an invalid cell mapping
21:22:07	melwitt	well, if there's an invalid cell_mapping, it's supposed to use the data from nova_api.build_requests
21:23:04	melwitt	rather, if InstanceMapping.cell_id=NULL it should be using nova_api.build_requests and using that to list and not failing
21:23:17	jroll	well, that's an empty table :/
21:23:39	melwitt	build_requests is empty?
21:23:57	jroll	yep
21:24:17	melwitt	huh. that is weird
21:24:23	jroll	indeed
21:24:38	mriedem	pretty sure it doesn't work that way
21:24:46	mriedem	this is the same thing surya was talking about on wednesday
21:24:56	mriedem	we look for a build request and if not there, we look for an instance mapping with a cell
21:25:17	mriedem	if the build request is gone, the instance mapping should have a cell mapping because we delete the build request after updating the instance mapping
21:25:36	melwitt	this shows if mapped, we look in the cell db, else we look at build requests https://github.com/openstack/nova/blob/stable/ocata/nova/compute/api.py#L2322-L2347
21:25:40	mriedem	https://bugs.launchpad.net/nova/+bug/1773945
21:25:41	openstack	Launchpad bug 1773945 in OpenStack Compute (nova) "nova client servers.list crashes with bad marker" [Medium,Triaged] - Assigned to Surya Seetharaman (tssurya)
21:26:12	mriedem	ok, but could be hitting ^
21:26:20	mriedem	where the build request is gone but the instance mapping doesn't have a cell mapping in it
21:26:28	melwitt	ah, okay
21:27:14	melwitt	jroll: build requests don't get soft-deleted so could be empty if everything got cleaned up properly
21:27:32	jroll	oh nice, thanks mriedem
21:28:01	melwitt	your traceback is different than that one, but could it be the same root cause?
21:28:24	jroll	probably
21:29:02	jroll	I have to bounce but pointed internal folks at that bug and the one I filed
21:29:14	jroll	I can update monday if they found anything new
21:29:58	jroll	thanks for all the help melwitt, mriedem
21:30:23	melwitt	based on your traceback, it looks like the instance get_all from compute/api succeeded but then you failed when the REST API code tried to access instance.get_flavor(), it wanted to lazy-load it. but that attribute should have been pre-loaded. so I don't get that yet
21:31:36	melwitt	jroll: thanks for letting us know about the bug
21:32:08	mriedem	that lazy load failure sounds familiar
21:34:03	mriedem	https://github.com/openstack/nova/commit/5a363a0d72e7dd8d79d7e950effc1d8a5fdc801b#diff-1b01e8e37be9d889295e5333b7857139
21:34:30	mriedem	that's likely not it
21:34:34	mriedem	probably something else in the api code
21:38:35	melwitt	so they get here and fail during flavor lazy-load https://github.com/openstack/nova/blob/stable/ocata/nova/api/openstack/compute/servers.py#L369 but it seems "impossible" that they could have gotten there with cell_id=NULL + build_requests table empty
21:39:46	melwitt	oh actually that's get_all so different than what I was looking at get earlier
21:43:37	melwitt	okay so that does make sense, the get_all in compute/api would find whatever is in the cell dbs regardless of cell_mapping=None. so that would succeed. but should also have flavor preloaded on the instance objects returned, so why is a lazy-load happening
21:44:18	melwitt	nothing should have been created from build requests if the build_requests table is empty...
21:47:09	melwitt	maybe he tried that test earlier when there were build requests still. that would make sense, if some items in the instance list were "shell" instances created from build_requests, then instance.get_flavor() would trigger a lazy-load
21:56:09	melwitt	jroll: if you could show nova_cell0.instance_extra for that instance it might help too
21:58:27	melwitt	maybe not actually. I was trying to think whether the embedded flavor was even there but it might not be relevant

02:21:50	pvc	hi
02:21:52	pvc	anyone can help me
02:23:22	naichuans	pvc: vgpu still doesn't work?
02:24:12	pvc	how can i share my GTX 1080 TI to 2 instance?
02:24:14	pvc	is that possible?
02:24:48	pvc	https://www.openstack.org/assets/presentation-media/Enable-GPU-virtualization-in-OpenStack.pdf
02:24:48	naichuans	If you are using passthrough, I think you can't share it among VMs
02:25:01	pvc	so what is alternative to passthrough?
02:25:21	pvc	this ? https://docs.openstack.org/nova/queens/admin/virtual-gpu.html
02:27:30	naichuans	You can use vgpu type support in XenServer, I can help you with it. But if you are using KVM, you need to talk with bauzas, who is an expert on vgpu in libvirt.
02:36:31	naichuans	pvc: The basic virtual vgpu should be support for a long time, make sure you are using the latest source code and set white list in nova.conf
02:37:47	naichuans	like http://paste.openstack.org/show/723145/, but at first check KVM setting, I haven't check it on KVM.
02:38:13	naichuans	guild https://specs.openstack.org/openstack/nova-specs/specs/queens/implemented/add-support-for-vgpu.html
02:38:36	naichuans	omit n-rp support
