#openstack-nova - 2017-01-17
18:48:17 owalsh mriedem: install ocata, from newton
18:48:54 mriedem ok.
18:48:55 melwitt mriedem: sweet, nice work
18:49:02 mriedem when coming from newton you'd have the nova and nova_api dbs
18:49:08 mriedem you still have to create cell0
18:49:14 owalsh ah, yes, typo
18:49:16 mriedem and sync it and map it
18:49:45 owalsh yea, but after sync api db
18:49:58 owalsh if it did have that migration
18:50:06 owalsh s/did/didn't/
18:50:58 mriedem well,
18:51:51 mriedem the upgrade scenario we had in mind was install ocata, create cell0 db, run simple_cell_setup which creates the cell0 mapping in the api db, runs the db schema migration on cell0, and then does map_cell_and_hosts for the existing nova database
18:52:00 mriedem ^ is what grenade does
18:52:23 mriedem https://github.com/openstack-dev/grenade/blob/master/projects/60_nova/from-newton/upgrade-nova
18:52:58 mriedem the problem is upgrading from newton to ocata with no compute hosts
18:53:07 mriedem but having flavors
18:53:15 mriedem which is not something we anticipated
18:55:31 openstackgerrit Diana Clarke proposed openstack/nova: nova-manage docs: cell_v2 create_cell https://review.openstack.org/421444
18:55:35 owalsh where/when is the api db sync?
18:59:31 mriedem after ^
19:00:36 mriedem here https://github.com/openstack-dev/devstack/blob/master/lib/nova#L681
19:00:57 melwitt this is reminding me what I said in the ML thread about the setup docs, we need to include step-by-step instructions for each common scenario

19:02:19 mriedem before you ask me why we recreate the nova_api db after upgrading from ocata, that's a good question
19:03:29 mriedem melwitt: i think you just signed up for that
19:04:25 melwitt yeah, I should do that :)
19:06:21 mriedem i'm not entirely sure what goes on with the dbs in grenade
19:08:18 mriedem sdague: is https://github.com/openstack-dev/devstack/blob/master/lib/nova#L676 not called during grenade?
19:11:25 mriedem oh i guess not
19:11:33 mriedem which is why we don't stomp on the databases from the n-1 run
19:12:08 mriedem ok i'm going to be away for awhile
19:12:20 owalsh mriedem: me too, thanks!

21:00:33 claudiub|2 mriedem: hi. around?
21:02:12 openstackgerrit Davanum Srinivas (dims) proposed openstack/nova: [WIP] ignore me - trying experimental jobs https://review.openstack.org/421209
21:09:47 harlowja mriedem if u get a chance, when this is ok, https://review.openstack.org/#/c/421482/
21:10:16 harlowja need for a oslo.serialization release that will unify the exceptions (until then cinder uses one type, nova uses the other, so its a PITA, lol)
21:11:07 smcginnis Hah - "can proceed with breaking nova"
21:11:22 efried I was amused
21:11:27 smcginnis efried: ;)
21:13:52 openstackgerrit Chris Dent proposed openstack/nova: Remove invalid URL in gabbi tests https://review.openstack.org/421529
21:13:58 cdent dims ^
21:14:31 cdent I'm not sure if I tidied up the py3 blacklist file properly or not, but if not, let me know and I'll fix it tomorrow, I'm done with today
21:16:39 nicolasbock Hi! I am trying to understand how nova-metadata works. I got to the point where I am reading nova/api/metadata/base.py:InstanceMetadata.get_ec2_metadata()
21:16:57 nicolasbock I suppose that this method returns the ssh public key for instance
21:17:22 nicolasbock how does this work though when I enable ssl in nova?
21:18:00 nicolasbock cloud-init in a server will request http://169.254.169.254/latest/.... and nova-metadata will expect an ssl connection
21:18:04 nicolasbock wouldn't that clash?
21:27:11 harlowja smcginnis oops, haha
21:27:18 smcginnis harlowja: ;)
21:27:38 openstackgerrit Joshua Harlow proposed openstack/nova: Handle oslo.serialization type error and binascii error https://review.openstack.org/421482
21:42:06 openstackgerrit Ed Leafe proposed openstack/nova: Add check for invalid allocation amounts https://review.openstack.org/416752
21:42:06 openstackgerrit Ed Leafe proposed openstack/nova: Remove the Allocation.create() method. https://review.openstack.org/416751
21:42:45 edleafe bauzas: found a bug in your recent merge: https://review.openstack.org/#/c/392569/27/nova/tests/functional/api/openstack/placement/fixtures.py@106 (and line 112)
21:43:11 edleafe bauzas: there is a step_size of 10, but an allocation of 512, which should fail, but doesn't
21:43:33 edleafe bauzas: the change to AllocationList.create_all() caught it
21:50:52 openstackgerrit Jiri Suchomel proposed openstack/nova: Retry few times when creating the initial connection to libvirtd. https://review.openstack.org/416928
21:54:43 bauzas edleafe: not sure it's due to my bug but okay:)
21:57:51 edleafe bauzas: when you added the step_size, min_unit, and max_unit, the subsequent allocation should have failed, since 512 isn't a multiple of 10
21:58:07 edleafe The old code happily created the allocation
21:58:13 edleafe The new code won't
21:59:09 siva_krishnan tdurakov ?
22:00:36 tdurakov siva_krishnan: hi, what's up?
22:01:09 openstack Launchpad bug 1647451 in OpenStack Compute (nova) "duplicate for #1599057 Post live migration step could fail due to auth errors" [Medium,Fix released] - Assigned to Timofey Durakov (tdurakov)
22:01:09 siva_krishnan this is regarding bug https://bugs.launchpad.net/nova/+bug/1599057
22:01:47 bauzas edleafe: but I haven't provided the allocation API, right?
22:02:00 tdurakov Yes
22:02:05 bauzas unless I misunderstand
22:02:40 siva_krishnan tdurakov: my intent of putting up patch for that bug is to do rollback on exception which occurs prior to live migration
22:03:21 slaweq oomichi: hello
22:03:51 slaweq oomichi: can You maybe look at https://review.openstack.org/#/c/420176/ ?
22:04:01 slaweq oomichi: I answered to Your comment there
22:04:16 siva_krishnan as you mentioned the bug description says the timeout happened during post live migration
22:04:19 slaweq oomichi: and I want to know what You think a about it
22:05:06 tdurakov siva_krishnan: yes, I understand that, the thing is that trying to call rollback here could be very tricky
22:05:26 edleafe bauzas: nothing to do with the API
22:05:53 tdurakov E.g. Exception is raised during roll-back itself
22:06:01 edleafe bauzas: In the change I referenced you added constraints to the inventory in the fixture that should have made the subsequent allocations invalid
