| 14:37:50 | mtreinish | see the second example in the readme | |
| 14:38:30 | sdague | mtreinish: or just use keystoneauth1 | |
| 14:44:45 | tonyb | mriedem: is the photo at 9:50 today (i.e in ~5mins)? | |
| 14:45:18 | mriedem | tonyb: yes | |
| 14:45:25 | mriedem | get your monacle ready | |
| 14:47:14 | tonyb | \o/ | |
| 14:51:14 | browne | mriedem: now that we're on pike and ocata is out the door, want to review https://review.openstack.org/#/c/425958/ again | |
| 14:51:31 | browne | rpc version updates | |
| 14:55:57 | mriedem | yeah, when we get a break | |
| 14:56:01 | rpodolyaka | sdague: I was talking about this one - https://review.openstack.org/434843 | |
| 15:00:32 | mriedem | sdague: i mentioned this the other night https://review.openstack.org/#/c/432699/ - if we default nova to use cinder v3 in pike, then we'll want that to explicitly run grenade on master changes with cinder v2 so we don't lose coverage there | |
| 15:06:56 | ildikov | Cinder-NOva session etherpad: https://etherpad.openstack.org/p/ptg-pike-cinder-nova-session | |
| 15:09:38 | sdague | mriedem: sure, that's fine | |
| 15:11:46 | diablo_rojo | Live stream of multiattach discussion with Cinder: http://youtu.be/MMTAJSYHxgA | |
| 15:12:26 | sdague | mriedem: actually... I'm not convinced we want to do that. We can talk about it later. | |
| 15:13:55 | sdague | dansmith: https://review.openstack.org/#/c/434843 doesn't hurt your cells db switcharoo, right? | |
| 15:14:34 | dansmith | sdague: not that I know of | |
| 15:15:30 | diana_clarke | diablo_rojo: Thanks! It's really nice being able to see the room. | |
| 15:18:43 | diablo_rojo | diana_clarke, no problem, the video will be up on our Cinder Youtube channel to reference back to as well :) | |
| 15:19:23 | mriedem | dansmith: https://review.openstack.org/#/c/373203/ | |
| 15:19:47 | openstackgerrit | Sylvain Bauza proposed openstack/nova-specs master: Super WIP: Placement doing claims https://review.openstack.org/437424 | |
| 15:23:04 | openstackgerrit | Takashi NATSUME proposed openstack/nova master: api-ref: Fix keypair API parameters https://review.openstack.org/420626 | |
| 15:24:25 | openstackgerrit | Takashi NATSUME proposed openstack/nova master: api-ref: Fix keypair API parameters https://review.openstack.org/420626 | |
| 15:30:18 | thorst | mriedem: FYI that I talked to sreeram_v. It doesn't sound like what we did for PowerVM & NPIV will work for the z-dpm stuff. | |
| 15:30:55 | mriedem | thorst: ok, i didn't understand the problem in the first place | |
| 15:31:52 | thorst | mriedem: I can catch you and explain it...its weirdness relating to virtualizing fibre channel. | |
| 15:32:12 | thorst | and differences between how hypervisors do NPIV. | |
| 15:32:37 | openstackgerrit | Maciej Jozefczyk proposed openstack/nova master: Ensure that instance directory is removed after success migration/resize https://review.openstack.org/437356 | |
| 15:33:04 | sreeram_v | mriedem: yep, we can discuss during the break | |
| 15:33:07 | mriedem | thorst: ok explain NPIV to me first | |
| 15:33:35 | sreeram_v | mriedem: this explains the reason on why we do prep_for_spawn before the spawn() https://github.com/openstack/nova-dpm/blob/master/nova_dpm/virt/dpm/driver.py#L223 | |
| 15:33:43 | thorst | yeah...can't wait to explain the joy that is NPIV. | |
| 15:39:26 | tonyb | mriedem: when you have time can you +1 https://review.openstack.org/#/c/437167/ and https://review.openstack.org/#/c/437165 | |
| 16:04:13 | mriedem | jaypipes: when does https://review.openstack.org/#/c/437165/2/gerrit/projects.yaml@5623 get into git.o.o? | |
| 16:05:21 | jaypipes | tonyb: ^^ ? | |
| 16:06:13 | sdague | mriedem: when it gets approved | |
| 16:06:26 | sdague | with some delay | |
| 16:06:44 | sdague | manage-projects script runs at some point and should do the import | |
| 16:07:28 | mriedem | when 437165 gets approved? | |
| 16:07:44 | sdague | mriedem: after it gets approved, i think manage-projects runs on a cron | |
| 16:08:06 | mriedem | fine +1 | |
| 16:08:30 | tonyb | mriedem: like what sdague said ;P | |
| 16:12:21 | mriedem | johnthetubaguy: L21 here for evacuate notes https://etherpad.openstack.org/p/ptg-pike-cinder-nova-session | |
| 16:12:23 | mriedem | since i'm lost | |
| 16:23:01 | mriedem | jaypipes: pay attention here | |
| 16:25:26 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: fix missing instance.delete notification https://review.openstack.org/437222 | |
| 16:32:46 | openstackgerrit | Maxim Nestratov proposed openstack/nova master: libvirt: Fix misleading error in Ploop imagebackend https://review.openstack.org/437512 | |
| 16:33:00 | openstackgerrit | Takashi NATSUME proposed openstack/nova master: Refactor a test method including 7 test cases https://review.openstack.org/395436 | |
| 16:35:19 | ildikov | johnthetubaguy: you can add me to the Nova spec too for the new Cinder attach/detach flow | |
| 16:35:33 | ildikov | johnthetubaguy: if nothing else I'll do some testing, etc. | |
| 16:43:29 | openstackgerrit | Sujitha proposed openstack/nova master: Change tags to default field in Instance object. https://review.openstack.org/415298 | |
| 16:43:54 | diana_clarke | Oh, a new exciting angle ;) | |
| 16:44:00 | openstackgerrit | Sujitha proposed openstack/nova master: [WIP] Reduce calls to load_tags() to 0 https://review.openstack.org/435146 | |
| 16:45:19 | NostawRm | Think this makes the 7th openstack channel I've joined now... | |
| 16:45:30 | NostawRm | Not sure if this counts as a dev question, but I'm trying to figure out the best way to run some custom code before an instance is deleted. I see that nova has options for hooks, but also that this is deprecated and will be removed eventually. Is there a more appropriate way? It would not make sense to suggest it being an actual part of openstack since its unique to our case | |
| 16:46:04 | NostawRm | it would need to be done from outside the instance, I'm not going to ramble on about it too much, but its specifically trying to do a differential backup system but specifically only for ceph, and who knows, maybe it'll actually be worth a damn and offering to the actual nova project, but its still an idea right now that I'm trying to test. | |
| 16:46:27 | NostawRm | but it requires that a snapshot in ceph be kept on the instances disk, which means that when trying to delete or rebuild, it fails to remove the disk | |
| 16:47:13 | mriedem | NostawRm: most of us are in a room all week at the PTG so you're likely not going to get a discussion started here today, | |
| 16:47:30 | mriedem | NostawRm: i'd suggest asking the question in the dev mailing list, tag the subject with [nova] so it's filtered properly, | |
| 16:47:45 | mriedem | and explain the use case enough so that others can see if there is a generic way to solve it in nova | |
| 16:47:48 | mriedem | without using hooks | |
| 16:48:06 | NostawRm | ah, I see, didn't know that was going on, ty mriedem | |
| 16:49:23 | mriedem | there are notifications that nova emits when deleting an instance, so you could listen for when nova starts deleting the instance and do your backup, but it gets racy | |
| 16:50:57 | nic | Odds are good that you'll need to subclass/extend the virt driver with your own that does what you want, but that is the definition of "technical debt" | |
| 16:51:43 | nic | If you budget enough for the maintenance coding that will be required, it might turn out OK ;) | |
| 16:54:30 | openstackgerrit | Sujitha proposed openstack/nova master: Change tags to default field in Instance object. https://review.openstack.org/415298 | |
| 16:54:31 | openstackgerrit | Sujitha proposed openstack/nova master: Adding tags field to InstancePayload https://review.openstack.org/407228 | |
| 16:56:09 | openstackgerrit | Sujitha proposed openstack/nova master: [WIP] Reduce calls to load_tags() to 0 https://review.openstack.org/435146 | |
| 16:57:52 | NostawRm | heh, nic, that's likely what I'm looking at now, until I get happy enough with it to submit it for public scrutiny | |
| 17:01:50 | nic | We maintained our own Nova virt driver for years with various custom features for our clients, but as of Liberty we were able to use the stock driver. It's better to not chase code. | |
| 17:06:05 | NostawRm | I would hope that this method would work well enough that others would want it and it would make it into the stock driver, but I'll be a bit honest, I'm not sure of that just from the fact that I've seen a lot of people ask for it and I'm working on custom because its not there | |
| 17:07:16 | NostawRm | Because I've had to read through the code to get an idea of what I want, I can kind of picture how it would go in, but who knows if I could work that out, kind of a nublet | |
| 17:25:11 | openstackgerrit | Luigi Toscano proposed openstack/nova master: More usage of ostestr and cleanup an unused dependency https://review.openstack.org/437536 | |
| 18:02:52 | johnthetubaguy | ildikov: you mean this one? https://review.openstack.org/#/c/373203/ | |
| 18:08:23 | openstackgerrit | Alex Xu proposed openstack/nova master: [placement] Add Traits related table to the api database https://review.openstack.org/376198 | |
| 18:30:55 | med_ | so, at lunch someone mentioned a "--failure" flag that meant nothing to me. I was too gutless to ask at lunch what that meant. Oddly hard to google for. If someone could cluebat me with the obvious I would be forever grateful. | |
| 18:31:14 | dansmith | med_: are you thinking of me talking about --failing? | |
| 18:31:18 | openstackgerrit | Maxim Nestratov proposed openstack/nova master: libvirt: Fix misleading error in Ploop imagebackend https://review.openstack.org/437512 | |
| 18:31:27 | med_ | ah yes. so I failed many ways | |
| 18:31:31 | dansmith | med_: when messing with unit tests, you can re-run just the ones that failed last time by doing "tox -epy27 -- --failing" | |
| 18:31:39 | med_ | danke. | |
| 18:32:12 | med_ | dansmith, so now twice in one conference, I've more or less misquote misremembered what you said. I think you should add me to your /ignore list | |
| 18:35:42 | ildikov | johnthetubaguy: yes :) | |
| 18:39:43 | openstackgerrit | Sujitha proposed openstack/nova master: Remove mox from nova/tests/unit/api/openstack/compute/test_create_backup.py https://review.openstack.org/435610 | |
| 18:52:20 | openstackgerrit | Lee Yarwood proposed openstack/nova master: Make BlockDeviceMapping object support uuid https://review.openstack.org/242603 | |
| 18:52:23 | openstackgerrit | Lee Yarwood proposed openstack/nova master: Add uuid column to BlockDeviceMapping https://review.openstack.org/242602 | |
| 18:57:28 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Improve assertJsonEqual error reporting https://review.openstack.org/428199 | |
| 19:05:19 | openstackgerrit | Stephen Finucane proposed openstack/nova master: libvirt: drop MIN_QEMU_NUMA_HUGEPAGE_VERSION https://review.openstack.org/437560 | |
| 19:05:19 | openstackgerrit | Stephen Finucane proposed openstack/nova master: libvirt: drop MIN_LIBVIRT_NUMA_VERSION https://review.openstack.org/437561 | |
| 19:05:20 | openstackgerrit | Stephen Finucane proposed openstack/nova master: libvirt: drop MIN_LIBVIRT_HUGEPAGE_VERSION https://review.openstack.org/437562 | |
| 19:05:30 | sfinucan | mriedem2: ^ | |
| 19:05:54 | oomichi | alex_xu: I found some non-good api on tempest https://review.openstack.org/#/c/435630 . https://developer.openstack.org/api-ref/compute/?expanded=check-tag-existence-detail#check-tag-existence should be HEAD, not GET | |
| 19:10:20 | bauzas | yay, Launchpad timeout issue \o/ | |
| 19:17:10 | mriedem | sfinucan: yeah so you found out why i didn't tackle the numa stuff right? :) | |
| 19:17:13 | mriedem | b/c of the test gorp | |
| 19:18:22 | sfinucan | mriedem: Aye. Looked tough until I realised having hugepages meant having NUMA support :) | |
| 19:18:49 | sfinucan | *needed NUMA support | |
| 19:18:58 | sfinucan | ...and having NUMA support implicitly meant you had huge page support | |
| 19:19:25 | sfinucan | Hence, bye bye swathes of test code | |
| 19:38:47 | openstackgerrit | Anusha Unnam proposed openstack/nova master: Add unit tests for cinderclient https://review.openstack.org/437575 | |
