| 20:26:48 | dansmith | diana_clarke: looks good tome | |
| 20:26:51 | dansmith | also to me | |
| 20:27:41 | dansmith | diana_clarke: mriedem will -1 one time to eff up my stats, but otherwise I think it covers all the things | |
| 20:29:30 | mriedem | dansmith: EmilienM: jaypipes: postmortem https://review.openstack.org/#/c/418590/ +1 fwiw with a more detailed recap of my understanding of the issue the patch is trying to avoid/fix | |
| 20:29:39 | mriedem | i just got distracted with PTG talk in another channel | |
| 20:30:00 | dansmith | mriedem: it's not dead yet.. it's like peri-mortem | |
| 20:30:17 | EmilienM | mriedem: ack | |
| 20:30:40 | EmilienM | I like the idea of https://review.openstack.org/#/c/418590/ being backported fwiw | |
| 20:30:58 | EmilienM | I'm pretty sure it will really help deployers | |
| 20:31:23 | jaypipes | edleafe: https://github.com/openstack/nova/blob/master/nova/objects/resource_provider.py#L306 | |
| 20:31:56 | jaypipes | EmilienM: np :) | |
| 20:32:10 | edleafe | jaypipes: that's a static method that only updates the DB | |
| 20:32:30 | mriedem | EmilienM: so in retrospec, i guess we're going to need to figure out a working relationship on how to communicate to the tripleo guys that even though something is optional now, you're going to want to bake it into your tooling, because release notes aren't going to cut it | |
| 20:32:33 | edleafe | jaypipes: the object that called it is now stale | |
| 20:32:35 | mriedem | *retrospect | |
| 20:32:49 | EmilienM | mriedem: I do agree | |
| 20:32:58 | mriedem | i.e. if nova has to touch grenade for ANY reason, someone from tripleo needs to know | |
| 20:33:08 | mriedem | s/tripleo/any of the 40 openstack deployment projects/ | |
| 20:33:12 | dansmith | mriedem: I was just about to say, it's in the grenade history | |
| 20:33:23 | jaypipes | edleafe: https://github.com/openstack/nova/blob/master/nova/objects/resource_provider.py#L372 | |
| 20:33:32 | jaypipes | edleafe: the object that called it is self. | |
| 20:33:34 | edleafe | jaypipes: IOW, if you make two set_inventory calls with the same object, the second will throw a ConcurrentUpdateDetected | |
| 20:33:46 | dansmith | mriedem: tempted to start up a twitter account and git commit hook :) | |
| 20:33:53 | mriedem | so i'll add something to the nova docs in our review guide - albeit chances are low anyone will read that | |
| 20:34:00 | mriedem | dansmith: you or me? | |
| 20:34:05 | dansmith | mriedem: I'm tempted | |
| 20:34:07 | jaypipes | edleafe: I don't believe that is true. | |
| 20:34:08 | EmilienM | mriedem: we are building a grenade like job in tripleo, where for the first time we'll test in gate upgrades with complex deployments | |
| 20:34:25 | EmilienM | mriedem: it might be useful to have the job in experimental pipeline in nova (one day) | |
| 20:34:40 | edleafe | jaypipes: I'm getting it in some of my tests. | |
| 20:35:03 | openstackgerrit | Claudiu Belu proposed openstack/nova: Adds Hyper-V OVS ViF driver https://review.openstack.org/140045 | |
| 20:35:06 | edleafe | jaypipes: let me see if there is somewhere else it is getting changed | |
| 20:36:47 | mriedem | EmilienM: well the thing is, placement and cells v2 were optional in newton, | |
| 20:37:00 | mriedem | so we had to explicitly enable those in specific jobs in newton to test them out | |
| 20:37:29 | mriedem | EmilienM: which takes the forethought to know you have to toggle those bits, we're missing that as part of our process right now for non-devstack/grenade things | |
| 20:47:17 | mriedem | diana_clarke: i'll approve the doc update once https://review.openstack.org/#/c/418590/ is merged | |
| 20:48:07 | diana_clarke | mriedem: thanks, I probably should have has a depends on | |
| 20:48:13 | diana_clarke | had | |
| 20:48:14 | openstackgerrit | Eric Fried proposed openstack/nova: Introduce base PowerVM driver https://review.openstack.org/391288 | |
| 20:49:03 | openstackgerrit | Matt Riedemann proposed openstack/nova: docs - Connect to placement service & retries https://review.openstack.org/419123 | |
| 20:49:09 | mriedem | diana_clarke: done | |
| 20:50:23 | openstackgerrit | Eric Fried proposed openstack/nova: WIP(2): Introduce base PowerVM driver (disk drv) https://review.openstack.org/409401 | |
| 20:50:36 | edleafe | jaypipes: found it. _check_capacity_exceeded() creates new RP objects, and these are the ones whose generation gets updated instead of the originals | |
| 20:50:39 | edleafe | jaypipes: https://github.com/openstack/nova/blob/master/nova/objects/resource_provider.py#L1078-L1081 | |
| 20:51:33 | openstackgerrit | Eric Fried proposed openstack/nova: WIP(3): Introduce base PowerVM driver (console) https://review.openstack.org/409402 | |
| 20:51:43 | dansmith | diana_clarke: mriedem: thanks | |
| 20:52:44 | EmilienM | diana_clarke: fyi, depends-on works for inter-projects connection, but for the same project, you better to use git rebase | |
| 20:52:58 | mriedem | dansmith: dash doesn't support multiple changes for the -c option does it...? | |
| 20:53:18 | mriedem | EmilienM: it's fine either way in this case | |
| 20:53:39 | EmilienM | right, just fyi again | |
| 20:54:13 | dansmith | mriedem: dunno, I never use that | |
| 20:54:19 | dansmith | mriedem: patches accepted :) | |
| 20:54:21 | openstackgerrit | Eric Fried proposed openstack/nova: WIP(4): Introduce base PowerVM driver (cfg drv) https://review.openstack.org/409404 | |
| 20:54:33 | diana_clarke | EmilienM: Oh right. I did know that, but I just drank some flu meds so I'm a bit groggy ;) | |
| 20:54:48 | EmilienM | diana_clarke: oops :-) | |
| 20:54:54 | mdrabe | dansmith: Is something enforcing having cells v2 in ocata? | |
| 20:55:41 | mriedem | mdrabe: yes, a db schema migration | |
| 20:55:41 | dansmith | mdrabe: various bits of cellsv2 have been required each release recently | |
| 20:55:43 | dansmith | mdrabe: there is more in ocata sure | |
| 20:55:57 | mriedem | mdrabe: you can't upgrade the api db schema without doing some setup first | |
| 20:56:33 | openstackgerrit | Jay Pipes proposed openstack/nova: placement: adds REST API for nested providers https://review.openstack.org/384807 | |
| 20:56:34 | openstackgerrit | Jay Pipes proposed openstack/nova: pci: add uuid field to PciDevice object https://review.openstack.org/414768 | |
| 20:56:34 | openstackgerrit | Jay Pipes proposed openstack/nova: placement: allow filter providers in tree https://review.openstack.org/377215 | |
| 20:56:35 | openstackgerrit | Jay Pipes proposed openstack/nova: placement: SRIOV PF devices as child providers https://review.openstack.org/414769 | |
| 20:56:36 | openstackgerrit | Jay Pipes proposed openstack/nova: placement: update client to set parent provider https://review.openstack.org/385693 | |
| 20:56:37 | openstackgerrit | Jay Pipes proposed openstack/nova: placement: add nested resource providers https://review.openstack.org/377138 | |
| 20:58:39 | jaypipes | edleafe: le sigh... yeah, line 1169 needs to be changed to: | |
| 20:58:41 | mdrabe | mriedem: What if you're starting fresh on ocata? | |
| 20:58:47 | jaypipes | rp.generation = _increment... | |
| 20:59:03 | openstackgerrit | Lee Yarwood proposed openstack/nova: libvirt: utils.get_disk return the target dev of the root device https://review.openstack.org/402716 | |
| 20:59:05 | openstackgerrit | Lee Yarwood proposed openstack/nova: libvirt: Make guest.BlockDevice only use the target dev of a disk https://review.openstack.org/402163 | |
| 20:59:05 | openstackgerrit | Lee Yarwood proposed openstack/nova: libvirt: Use the mirror element to detect when to pivot https://review.openstack.org/399735 | |
| 20:59:07 | mriedem | mdrabe: same deal | |
| 20:59:17 | mriedem | mdrabe: you still have to have a cell0 cell mapping record in the api db | |
| 20:59:28 | mriedem | actually... | |
| 20:59:31 | dansmith | mriedem: the blocker doesn't enforce that it's done first, | |
| 20:59:34 | mriedem | i think the db schema migration ends early | |
| 20:59:41 | dansmith | but you still need that | |
| 20:59:43 | mriedem | if there are no flavors in the api db then it's a noop | |
| 21:00:19 | mriedem | mdrabe: we're also working on this nova-status upgrade check CLI for checking this stuff at any time prior to install/upgrade | |
| 21:00:27 | mriedem | just haven't integrated that yet into the grenade tooling we have | |
| 21:06:56 | mdrabe | mriedem: So say I didn't have any cells in my deployment down the road, things are certainly not going to work right? The cells requirement isn't just for want? | |
| 21:07:12 | openstackgerrit | Jay Pipes proposed openstack/nova: pci: add uuid field to PciDevice object https://review.openstack.org/414768 | |
| 21:07:13 | openstackgerrit | Jay Pipes proposed openstack/nova: placement: update client to set parent provider https://review.openstack.org/385693 | |
| 21:07:13 | openstackgerrit | Jay Pipes proposed openstack/nova: placement: SRIOV PF devices as child providers https://review.openstack.org/414769 | |
| 21:07:31 | dansmith | mdrabe: you can have a cell of one, of course, if that's what you mean | |
| 21:07:48 | dansmith | mdrabe: everyone will be transitioning to a single-cell deployment all the time | |
| 21:08:08 | mdrabe | dansmith: But if I had none like we could in newton that's not gonna fly? | |
| 21:08:48 | dansmith | mdrabe: I'm not sure what you mean.. "one" cell is just a single row in the database -- nothing else is different | |
| 21:09:58 | dansmith | mdrabe: meaning, moving from a newton deployment to an ocata one with just one cell is just adding a row to the database, which says your existing stuff is "cell 1" | |
| 21:10:26 | dansmith | mdrabe: no extra services or configuration like normal cells (i.e. cellsv1) requires | |
| 21:11:04 | mdrabe | dansmith: But if I didn't have a single cell could I still deploy? | |
| 21:11:20 | dansmith | mdrabe: no, there's no such thing as "no cells" anymore | |
| 21:12:53 | dansmith | mdrabe: well, you could deploy with no cells, but you could never create any instances.. :P | |
| 21:14:08 | mdrabe | because the instance has to be built to a specific cell | |
| 21:14:55 | dansmith | yes | |
| 21:16:25 | openstackgerrit | Ed Leafe proposed openstack/nova: Fix missing RP generation update https://review.openstack.org/419137 | |
| 21:16:44 | edleafe | jaypipes: The fix ^^ | |
| 21:17:21 | jaypipes | edleafe: cheers man | |
| 21:17:28 | jaypipes | mriedem: I'm good with https://review.openstack.org/#/c/140045/ now. | |
