21:21:40 mordred I didn't do it
21:21:49 edmondsw lol
21:22:18 edmondsw I almost said "identity", and then remembered all the current sections are using codenames
21:22:25 edmondsw odd that nobody's changed that already...
21:22:34 efried edmondsw Yeah, I think mordred wants to push for that eventually.
21:23:06 efried edmondsw If we talk about it in -keystone and decide it's really a bug in ksm, then we could justify leaving it in [keystone_authtoken] and making a delta in nova.conf.workarounds to... work around it.
21:23:41 edmondsw efried sure, let's do that tomorrow, I have to run
21:24:07 efried rgr
21:54:04 mriedem dansmith: jaypipes: ok i went through https://review.openstack.org/#/c/491012/ and posted questions, several about evacuate from an ocata compute - i know dan is MIA now and i have to head out too, but will be back around later and tomorrow to discuss anything

#openstack-nova - 2017-08-10
00:30:50 masber good morning nova team, I am not sure whether this is the right place to ask this question (please forgive me if not) I am testing openstack vs raw performance in terms of disk latency using ioping and realized that disk latency from the host is around 159us whole on the vm is around 388us. Could someone please help me to understand why is that? thank you very much
00:31:31 masber by the way I am using openstack all in one flavor using packstack so instance storage is local lvm
00:48:08 openstackgerrit Merged openstack/nova master: Add release note for shared storage known issue https://review.openstack.org/491582

01:14:19 alex_xu that is fault of multiple screens

05:11:22 jianghuaw mriedem, thanks for the comments for https://bugs.launchpad.net/nova/+bug/1709594.
05:11:24 openstack Launchpad bug 1709594 in OpenStack Compute (nova) "live-migration without '--block-migrate" failed with "No sql_connection parameter is established"" [Undecided,New]
05:11:31 jianghuaw Yes, this is a devstack configuration and it's running in superconductor mode.
05:12:38 jianghuaw the database configuration in nova.conf is:
05:12:39 jianghuaw [database]
05:12:39 jianghuaw connection = mysql+pymysql://root:citrix@127.0.0.1/nova_cell0?charset=utf8
05:12:39 jianghuaw [api_database]
05:12:39 jianghuaw connection = mysql+pymysql://root:citrix@127.0.0.1/nova_api?charset=utf8
05:14:32 jianghuaw mriedem, the nova_api database connection settings seems correct.

08:19:01 gibi good morning
08:20:15 maciejjozefczyk hello
08:40:00 bauzas morning Novaists
09:05:37 ratailor alex_xu, you around ?
09:05:44 alex_xu ratailor: yea
09:06:17 ratailor alex_xu, regarding this bug https://bugs.launchpad.net/nova/+bug/1709260
09:06:20 openstack Launchpad bug 1709260 in OpenStack Compute (nova) "Addition of host to host-aggregate should be case -sensitive" [Low,Confirmed] - Assigned to Rajesh Tailor (ratailor)
09:06:52 ratailor alex_xu, I have done something like this.. https://github.com/openstack/nova/commit/402b3abf990d08d2af8331079d36a92d84d84b80#diff-342854d9b83486a3db6189bc21be6266L1026
09:07:24 ratailor alex_xu, for host_mappings table in api_db.
09:08:03 ratailor alex_xu, I was able to pass through this code block. https://github.com/openstack/nova/blob/master/nova/objects/host_mapping.py#L91-L93
09:09:21 alex_xu ratailor: not sure your first link is correct, that is pointed to a empty migration check
09:09:47 alex_xu ratailor: oh, sorry, I saw the entire patch now
09:10:19 alex_xu ratailor: I'm not sure we need to convert the table to case-sensitive
09:10:24 ratailor alex_xu, but again I got stuck in this code block. https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/api.py#L571-L575
09:10:29 alex_xu at least, the hostname should be case-insensitive
09:11:40 ratailor alex_xu, in that case, do I need to look for alternative approach if possible ?
09:14:04 alex_xu ratailor: I guess it won't work after you change the collation of the table? since the in-memory copy of host<->aggregation mapping in the scheduler is still case-sensitive
09:16:03 alex_xu ratailor: ah, I see, you want to stop the api user input a hostname which differnet with the Db one
09:16:20 ratailor alex_xu, I also applied the collation logic to service table in nova_cell1 db, but here, case-insensitive check is getting passed.
09:16:47 alex_xu but the hostname should be case-insensitive? whatever the user input COMPUTE0.example.com or compute0.example.com, it should works
09:17:01 ratailor alex_xu, yes, I wan't to prevent from adding the case-insensitive host to host-aggregate.
09:17:42 ratailor but aggregates store the hostname as COMPUTE0.example.com, whereas in db its compute0.example.com
09:18:16 ratailor alex_xu, so that is what might be confusing scheduler.
09:20:05 alex_xu ratailor: there is a related bug https://bugs.launchpad.net/nova/+bug/1538011
09:20:07 openstack Launchpad bug 1538011 in OpenStack Compute (nova) "Metadata keys are not case sensitive" [Medium,In progress] - Assigned to Augustina Ragwitz (auggy)
09:20:53 ratailor alex_xu, Thanks! let me check it.
09:21:09 alex_xu ratailor: it would be great to check those two bugs, see the best way to fix
09:21:22 ratailor alex_xu, sure.
09:22:33 alex_xu ratailor: and there is a spec for that bug https://review.openstack.org/#/c/350843/, but didn't get merged

10:01:58 cdent alex_xu: thanks alex, I’ve got that in my queue to look at soon. Was it hard to resolve?
10:02:14 bauzas alex_xu: thanks, will look to it asap
10:02:21 bauzas just have some internal paperwork to do
10:02:39 alex_xu cdent: after I pull some code into a sub-method, then thing gets a little better
10:02:55 cdent ah, yeah, good idea
10:04:07 maciejjozefczyk cdent: please add also this to your queue https://review.openstack.org/#/c/491808/
10:04:28 cdent maciejjozefczyk: already there
