#openstack-nova - 2017-05-19
01:23:33	mriedem	also fyi https://docs.openstack.org/developer/nova/cells.html#upgrade-minimal
01:24:02	mriedem	what you're hitting is this https://github.com/openstack/nova/blob/master/nova/cmd/manage.py#L649
01:24:11	mriedem	when it's trying to automatically sync the nova_cell0 database
01:25:16	mriedem	anyway, you shouldn't need to sync the db from the compute nodes
01:28:51	fishbone_	mriedem, are you saying the error can be ignored, I don't think I am able to compete the nova-compute installation because of this error
01:29:16	fishbone_	mriedem: Is there a way to suppress that sync process?
01:29:40	mriedem	i'm saying you don't need to sync the database from a compute node
01:29:49	mriedem	the compute node doesn't have direct access to the database
01:29:52	mriedem	or shouldn't
01:33:30	fishbone_	mriedem: Do you know why I may be getting that error on a compute host then?
01:34:04	fishbone_	mriedem: I get the error even if I do a fresh install of nova-compute after removing old cofig files
01:34:10	fishbone_	config*
01:34:52	mriedem	i assume because the compute host doesn't have direct access to the cell0 database
01:35:06	mriedem	but it's weird that the sync on the nova (cell) database would not fail in that case
01:35:45	mriedem	https://docs.openstack.org/ocata/install-guide-ubuntu/nova-compute-install.html doesn't say anything about running db sync from the compute host though
01:35:53	mriedem	that's all done on the controller https://docs.openstack.org/ocata/install-guide-ubuntu/nova-controller-install.html
01:37:22	fishbone_	mriedem: Yes it is strange, I get the error at the apt install nova-compute" step
01:37:43	mriedem	hmm, so that's something baked into the package then?
01:37:53	mriedem	like a post-install script as part of the package?
01:38:07	mriedem	are you using ubuntu packages?
01:38:22	fishbone_	mriedem: yes, I am using the ubuntu repositories
01:39:14	openstackgerrit	Jianghua Wang proposed openstack/nova master: Skip policy rules on attach_network for none network allocation https://review.openstack.org/465903
01:40:39	mriedem	fishbone_: ok well those seem wrong, i'd probably report a bug against the ubuntu nova package LP site
01:41:01	mriedem	fishbone_: on your control node, if you run "nova-manage cell_v2 list_cells" do you see 2 listed?
01:41:38	mriedem	https://launchpad.net/ubuntu/+source/nova for reporting bugs against ubuntu nova packages btw
01:42:37	mriedem	if list_cells shows 2 cells then i think you're good to go
01:46:56	fishbone_	mriedem: Yes it shows properly, however; the compute nodes are unable to install the appropriate packages
01:47:00	mriedem	mdbooth: lyarwood: btw, hooray for completely differnt code paths for attaching a volume during boot and after boot https://review.openstack.org/#/c/443951/18/nova/virt/libvirt/volume/vrtshyperscale.py@44
01:47:10	fishbone_	mriedem: they fail with the error
01:47:49	mriedem	fishbone_: is there a way to ignore post-install scripts, or force the install? sorry but i haven't heard of this one, definitely sounds like a bug in the assumptions the packages are making
01:48:51	mriedem	fishbone_: also https://ask.openstack.org/en/question/103660/ocata-install-nova-error/
01:49:26	fishbone_	mriedem: I haven't tried that, I will, and thanks for all your help, I'll update soon
01:50:14	mriedem	fishbone_: see if you have a nova_api_cell0 or nova_cell0 db
01:50:28	mriedem	you can also see that via nova-manage cell_v2 list_cells --verbose
01:50:43	mriedem	sounds like some people in that forum thread hit some issues with mismatched db names and the connection URL in the api db
01:50:44	mriedem	for cell0
01:50:49	fishbone_	mriedem: I saw that article, it didn't seem to work for me, I have the nova_cell0 database
01:51:08	mriedem	is that what's in the database_connection for the cell0 cell_mapping in the nova_api database though?
01:51:24	fishbone_	mriedem: I followed the docs, which say that it should be named as nova_cell0
01:51:40	mriedem	i'd check your db :)
01:51:46	fishbone_	mriedem: I cross referenced that in those 2 databases and they do match
01:51:51	mriedem	ok
01:56:08	openstackgerrit	guang-yee proposed openstack/nova master: make sure to rebuild claim on recreate https://review.openstack.org/466143

02:16:10	openstackgerrit	Zhenyu Zheng proposed openstack/nova master: Add tags fields for server list detail/show api-ref https://review.openstack.org/465842
02:22:07	fishbone_	mriedem: it seems to be an issue with the compute hosts themselves, I tried a fresh install with a host that was not already in the nova database and received no errors duing installation
02:22:42	fishbone_	mriedem: It must be specific to upgrading a pre-integrated hypervisor
02:44:43	fishbone_	mriedem: it seems simply adding the database directives in the config files allowed the install to go through, perhaps due to the hypervisors being from prior to the cell creation
02:54:53	openstackgerrit	Naichuan Sun proposed openstack/nova master: xenapi: cached images should be cleaned up by time https://review.openstack.org/465954
02:55:06	mriedem	fishbone_: hmm, not sure
02:55:17	mriedem	but cool that you found a workaround
02:55:28	mriedem	still, i'd open a bug against the ubuntu packagers,
02:55:34	mriedem	the nova-compute package shouldn't be running nova-manage db sync
02:57:20	openstackgerrit	Zhenyu Zheng proposed openstack/nova master: Should not allow security group from other project pass API layer check when booting https://review.openstack.org/466160

08:47:11	sfinucan	mdbooth: Seeing as you reviewed the original patch, does this patch follow-up make sense? https://review.openstack.org/#/c/466088/
09:03:54	sfinucan	ralonsoh: You about?
09:04:21	ralonsoh	sfinucan: hi!
09:04:32	sfinucan	ralonsoh: On https://review.openstack.org/#/c/449257/ - that usually happens when you accidentally re-upload an old revision
09:05:02	sfinucan	I would imagine you've reuploaded PS18 when you reuploaded the following patch
09:05:36	ralonsoh	sfinucan: hmmm, I'll check that, but I'm pretty sure I didn't do this
09:05:50	ralonsoh	sfinucan: but thank you for your explanation!
09:06:02	sfinucan	fwiw, you can fix it by downloading the last correct PS from the first patch (probably 20, so 'git review -d 449257,20')
09:06:19	ralonsoh	sfinucan: thanks!
09:06:27	sfinucan	ralonsoh: np ;)
