16:20:01 mnaser cfriesen: i'm assuming the code base doesn't actually touch anything if it's a resize
16:20:08 zcorneli dansmith: Ok, no worries
16:20:16 mnaser cfriesen: libvirt i assume?
16:22:28 cfriesen mnaser: yep
16:23:02 openstackgerrit Lee Yarwood proposed openstack/nova master: Add regression test for bug #1764883 https://review.openstack.org/562072
16:23:03 openstack bug 1764883 in OpenStack Compute (nova) "Evacuation fails if the source host returns while the migration is still in progress" [Undecided,In progress] https://launchpad.net/bugs/1764883 - Assigned to Lee Yarwood (lyarwood)

16:23:09 mriedem is the libvirt driver the only one (really) that supports swap disks? because that's what the api-ref says:
16:23:10 mriedem "Specifies the guest server disk file system format, such as ext2, ext3, ext4, xfs or swap. This parameter affects only the libvirt virt driver."
16:25:20 mriedem maybe that just means the non-swap values are only used by the libvirt driver
16:25:40 dansmith or that libvirt is the only one that makes filesystems on disks
16:25:46 mnaser ^
16:25:58 dansmith does't mean you don't get a swap disk according to the flavor,
16:26:08 dansmith you just might have some-assembly-required sort of deal
16:26:35 mriedem ok, it
16:26:50 mriedem it's just that "This parameter affects only the libvirt virt driver." is confusing since you have to specify guest_format='swap' to get a swap bdm attached
16:26:59 mriedem along with some other bdm field incantations
16:27:04 mriedem that aren't documented in the api ref
16:32:41 mnaser https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L8180-L8186
16:33:21 mnaser https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L8235-L8241
16:33:38 mnaser so because it already exists with ceph, it probably doesnt touch it
16:34:12 mnaser (i think..)
16:34:55 tasker hey, good morning. I'm checking up on https://review.openstack.org/#/c/550865/ . is there something else needed before it can be merged? also, is this review a candidate for backport to Pike?
16:34:59 cfriesen mnaser: we're seeing the underlying size change to the "new" size when doing a resize...but the guest needs to re-run "mkswap" to make use of the larger amount of space.
16:36:08 cfriesen mnaser: and if we revert the resize then the underlying size stays at the "new" size even after reverting, which would seem to be a resource tracking bug.
16:37:27 mnaser i can't even find the codebase where nova does mkfs
16:37:31 mnaser i can find the function calls..
16:38:52 mnaser ok _create_swap()
16:39:15 mnaser looks like mkswap only happens in _create_swap and nowhere else
16:39:27 mnaser idk if we want to call that a bug or not
16:39:42 mnaser i'd want to avoid touching underlying fs once something is booted
16:45:26 mriedem jaypipes: i made that server_default=text("0") model change for a reason, to match the db schema migration script; the fact it passes with sqlite and postgresql makes me think it's a bug in whatever mysql comparison code is happening, which zzzeek seems to agree with
16:45:44 tasker https://review.openstack.org/#/dashboard/self is only showing open reviews. isn't there a way to show all reviews that I've submitted?
16:46:21 mriedem tasker: https://review.openstack.org/#/q/owner:eric%2540awnix.com ?
16:46:41 tasker oh.
16:46:44 tasker thanks!
16:51:35 openstackgerrit Matt Riedemann proposed openstack/nova master: api-ref: expand on various bdm parameters https://review.openstack.org/574805
16:53:20 jaypipes mriedem: k. I haven't pushed any further update on that series...
16:53:44 mriedem jaypipes: having said that, i'm not sure what to do here, since i don't want to hold things up while a bug in a dependent library gets fixed
16:53:58 openstackgerrit Simon Dodsley proposed openstack/nova master: Add enhanced KVM storage QoS quotas https://review.openstack.org/558530
16:53:59 mriedem i guess i can respin, remove the model change, add a FIXME and report a bug to oslo.db
16:54:03 jaypipes mriedem: maybe we just put a TODO in there?
16:54:13 mriedem yeah i'll do that quick
16:54:15 jaypipes mriedem: or I can do it. just let me know.
16:54:31 mriedem i've got it local, 2 seconds
16:54:41 jaypipes k, thx mriedem
16:55:55 simondodsley_ mriedem: cinder docs review added https://review.openstack.org/#/c/574804/
16:55:56 cfriesen mnaser: for what it's worth, for "local" filesystems we don't copy over the swap file but instead create a whole new one, so the guest sees the "right" swap size when it boots up after the resize.
16:56:30 mnaser cfriesen: ah you are right about that one, so we do kinda make the drive disappear with resize
17:07:22 openstackgerrit Merged openstack/nova master: Use instance project/user when creating RequestSpec during resize reschedule https://review.openstack.org/571245
17:12:35 openstackgerrit Chris Dent proposed openstack/nova master: Optional separate database for placement API https://review.openstack.org/362766

17:13:21 openstackgerrit Chris Dent proposed openstack/nova master: Add PLACEMENT_DB_ENABLED=True to the nova-next job https://review.openstack.org/564067
17:15:01 openstackgerrit Matt Riedemann proposed openstack/nova master: add consumers generation field https://review.openstack.org/557958
17:15:04 mriedem jaypipes: ^ but i gave up on trying to rebase the series after https://review.openstack.org/#/c/572280/ caused merge conflicts
17:15:08 mriedem i'll leave that rebase to you
17:22:32 jaypipes mriedem: roger
17:24:13 openstackgerrit Merged openstack/nova master: libvirt: Don't report DISK_GB if sharing https://review.openstack.org/560459
17:44:44 tasker mriedem: is there something that needs to be done for https://review.openstack.org/#/c/550865/? also, can it be backported to Pike, or is that window closed? ( re: https://bugs.launchpad.net/nova/+bug/1754360 )
17:44:46 openstack Launchpad bug 1754360 in OpenStack Compute (nova) "no unquiesce for volume backed on quiesce failure" [Medium,In progress] - Assigned to Eric M Gonzalez (egrh3)
17:45:32 cdent mriedem: is "oslo_policy/policy.py:865: UserWarning: Policy placement:resource_providers:traits:update failed scope check. The token used to make the request was project scoped but the policy requires ['system'] scope. This behavior may change in the future where using the intended scope is required" something you're already aware of and I don't need to think about?
17:48:37 mriedem tasker: just requires reviews; pike is open for backports
17:49:13 mriedem tasker: and for a long time https://superuser.openstack.org/articles/extended-maintenance-openstack/
17:51:07 mriedem cdent: i'm aware of it, and slightly annoyed at how verbose that is
17:51:11 mriedem especially if it's not cached
17:51:16 openstackgerrit Chris Dent proposed openstack/nova master: Use nova.db.api directly https://review.openstack.org/543262
17:51:36 mriedem basically if you have a scope type set on a policy rule that gets used, and enable_scope=False (the default) then you get spammed with warnings
17:51:40 cdent mriedem: yeah. you kinda wanna be able to say omg, I know
17:51:50 mriedem probably needs to be a bug in oslo.policy

18:10:49 mriedem bpoulos: you moved https://review.openstack.org/#/c/479949/76..77/nova/compute/manager.py but didn't move the related unit test
18:13:46 mriedem oh nvm i guess it's here https://review.openstack.org/#/c/561262/26/nova/tests/unit/compute/test_compute_mgr.py
18:17:20 mriedem bpoulos: ok there is just 1 missing test in https://review.openstack.org/#/c/479949/ - i can add that if you like
18:22:38 bpoulos mriedem: that would be great, thanks!
