#openstack-nova - 2017-10-13
01:48:15 sapd_ But service with id 67 was nova-compute ocata, and It was deleted dansmith
01:48:31 sapd_ The new service with id 95
01:51:20 sapd_ The compute name is compute-1, I saw three records in services table in nova_cell1 database
02:00:08 alex_xu efried: the aggregate/shared is the most complex part, previous implementation is using the sql building the mapping between shared rp and root rp, currently we move that into the python code
02:00:54 alex_xu efried: the basic logic is ensure the correct combination of the root rp and shared rp, and find out the traits in those combination
02:03:50 sapd_ hi dansmith! I fixed that error, I deleted two records of a compute service.
02:07:18 alex_xu gmann: fyi, we got some feedback from nova meeting http://eavesdrop.openstack.org/meetings/nova/2017/nova.2017-10-12-21.00.log.html#l-90
02:15:59 gmann alex_xu: yea i saw. i will update BP/spec accordingly
02:22:27 alex_xu gmann: thanks

03:20:08 vivsoni from pike onwards, do we have some other flag to enable multipath .. other than 'volume_use_multipath = True'
03:21:23 vivsoni In case of FC, i am able to see multiple vlun, but ISCSI there is only one vluns created after cinder volume attached to nova instance
03:23:05 vivsoni the 'connector' value passed to cinder's driver code 'initialise_connection' function does have 'multipath=False' instead of 'multipath=True' in case of ISCSI

11:53:03 epalper hi, I'm trying to nova vm from opnfv functest deployment seeing the following error in nova-compute.log
11:53:05 epalper https://paste.ubuntu.com/25731708/
11:53:39 epalper could you please tell me what is going on during nova boot ?
12:04:48 efried alex_xu What's the best source of information for me to understand the semantics of shared/aggregates?
12:05:05 efried Is there a nice doc? Is it described in a spec?
12:05:20 efried I pawed around specs a bit yesterday and couldn't find what I was looking for.

13:23:02 mriedem melwitt: so did you and dan get to the bottom of https://launchpad.net/bugs/1722404 ?
13:23:05 openstack Launchpad bug 1722404 in OpenStack Compute (nova) pike "Database transactions can fail with "TypeError: Can't upgrade a READER transaction to a WRITER mid-transaction" because of scatter_gather_cells" [High,In progress] - Assigned to melanie witt (melwitt)
13:25:47 melwitt mriedem: not 100% sure yet but it makes sense and looks promising based on my local unit test reproducer. dansmith has a patch up https://review.openstack.org/#/c/511651
13:25:48 openstackgerrit Dmitry Tantsur proposed openstack/nova master: Pick ironic nodes without VCPU set https://review.openstack.org/511844
13:25:55 dtantsur fallout from our inventory work in the end of Pike ^^^ vdrok FYI
13:26:56 melwitt mriedem: the theory is that the culprit is we only do a shallow copy.copy() of the context when we return a new RequestContext during cell targeting, and that makes hidden oslo.db state get shared across the threas
13:26:58 melwitt *threads
13:30:40 dansmith melwitt: I'll write some tests for that
13:32:31 mriedem melwitt: dansmith: queried logstash on those warnigns,
13:32:38 mriedem linked the results in the change, there are quite a few hits on both
13:32:48 dansmith yep, I know of a couple places that will trigger it
13:33:04 dansmith mriedem: well, one of the warnings that is.. do you see both?
13:33:12 mriedem yes
13:35:14 dansmith okay, so that's actually good,
13:35:29 dansmith because it plays into the theory that we leak that internal context somewhere across a target
13:38:38 melwitt cool. yeah, the more I've thought about it, the more I think that's what it is
13:40:03 mriedem bauwser: replied in https://review.openstack.org/#/c/501017/

13:45:33 Laurene mriedem: Hi,We're requesting +1/-1 reporting permission to Nova changes for IBM zVM CI. Can you help me to resolve it ?

13:46:03 melwitt mriedem, dansmith: I'm gonna be heading out for a weekend trip in about an hour, so just FYI
13:47:26 fried_rice melwitt You real busy til then? Feel like reviewing a spec? :*
13:47:55 dansmith melwitt: okay

13:50:25 melwitt fried_rice: hah
13:51:01 openstackgerrit Eric Fried proposed openstack/nova master: Convenience Allocations objects for compute https://review.openstack.org/511831
13:51:21 fried_rice d'oh, forgot to git add test suite, fixed ^
13:54:13 superdan mriedem: you want me to closes-bug: #1722404 on this patch right?
13:54:14 openstack bug 1722404 in OpenStack Compute (nova) pike "Database transactions can fail with "TypeError: Can't upgrade a READER transaction to a WRITER mid-transaction" because of scatter_gather_cells" [High,In progress] https://launchpad.net/bugs/1722404 - Assigned to melanie witt (melwitt)
13:55:48 openstackgerrit Dmitry Tantsur proposed openstack/nova master: Pick ironic nodes without VCPU set https://review.openstack.org/511844
13:55:53 dtantsur this ended being a can of worms, but I guess that's the complete fix ^^^
13:57:35 mriedem superdan: sure
13:57:50 openstackgerrit Dan Smith proposed openstack/nova master: Regenerate context during targeting, and sanity check some things https://review.openstack.org/511651
13:58:09 superdan mriedem: should we revert the previous patch or just note it on the bug?
13:58:24 mriedem superdan: so the previous patch doesn't fix anything right? does it hurt anything?
13:58:34 mriedem Laurene: done
14:01:11 Laurene mriedem:That's great! thanks very much!
14:01:14 melwitt mriedem: it increases contention for the cell cache so should probably revert it
14:02:11 superdan mriedem: it doesn't fix anything, but it does mean that the threads get untargeted contexts and are required to target them themselves, which is a little less clean I think
14:10:17 superdan mriedem: I'm hoping that this will get rid of the transaction context warning, and yeah I can track down the re-targeting warning in later patches
14:10:40 superdan mriedem: would you rather me separate the fix and the warnings so we don't backport the warnings?
