| 13:56:51 | cdent | so being able to say “put some allocations for both this migration uuid and this consumer uuid in one go”? | |
| 13:56:54 | cdent | jinx | |
| 13:57:11 | dansmith | without this, I could delete the instance allocation and create the migration one, but there's a race, or reverse that, but then I need twice the space available for a second | |
| 13:57:16 | dansmith | cdent: yes, that | |
| 13:57:59 | dansmith | cdent: so right now I'm doing the safer option which will fail if computes are full, but I think we should go for the atomic swap before we call this done | |
| 13:58:14 | cdent | one way to do that woudl be POST /allocations | |
| 13:58:31 | cdent | in fact I would say that’s probably the only way to do that | |
| 13:59:03 | dansmith | https://review.openstack.org/#/c/498949/1/nova/compute/manager.py | |
| 13:59:09 | dansmith | L3801 here is the first example | |
| 13:59:22 | cdent | yeah, I was just through there a few minutes ago | |
| 13:59:32 | dansmith | okay cool, so could you cook that up for us? | |
| 14:00:08 | cdent | yeah, shouldn’t be too hard, I’m trying to think what the body should look like | |
| 14:00:28 | cdent | we’ve already complained about this mismatch between GET and PUT on /allocations/{c_u} | |
| 14:00:51 | cdent | so if we’re considering changing the PUT format, then would be best to make POST similar to that | |
| 14:01:05 | dansmith | well, | |
| 14:01:26 | dansmith | POST of multiple things being slightly different than a PUT of one is less terrible than PUT/GET of a single thing being different | |
| 14:01:33 | cdent | we’ll also want to decide, sooner than later, if this POST is only for one project_id, user_id pair, or can be mixed? | |
| 14:01:38 | dansmith | but yeah, whatever we need to do.. | |
| 14:01:56 | cdent | dansmith: yeah, sure, but it’s a question of list or dict being the fundamental structure | |
| 14:01:56 | dansmith | well, for this we only need it to apply to a single project/user | |
| 14:02:04 | dansmith | ack | |
| 14:02:27 | cdent | I’ve got a nine hour flight tomorrow, I’ll see if I can make it happen then | |
| 14:02:50 | dansmith | theoretically you wouldn't (or shouldn't) need atomic operations across tenants/users, but I'm also not sure there's a good reason to specifically design it not to work | |
| 14:03:18 | dansmith | cdent: cool, decide on these things, put it in a spec calling out the potential questions and we can go from there | |
| 14:03:29 | cdent | ✔ | |
| 14:03:42 | dansmith | thanks! | |
| 14:04:26 | cdent | a pleasure. it feels like it’s been a while since I’ve written much code | |
| 14:05:45 | cdent | edleafe, jaypipes : if you have any ideas/concerns with what dan and I just discussed ^ please let me know before tomorrow morning (I’ll see about cooking a quick spec sooner) | |
| 14:10:42 | mriedem | o/ | |
| 14:11:36 | edleafe | cdent: this would be a PUT against /allocations (no {consumer_uuid}), right? | |
| 14:12:05 | cdent | edleafe: I’m thinking POST as PUT would imply a replace of _all_ allocations | |
| 14:13:12 | dansmith | cdent: all allocations for any consumer specified in the body you mean | |
| 14:13:20 | mriedem | efried: can you redo this with the -x option for git cherry-pick? https://review.openstack.org/#/c/498463/ | |
| 14:13:33 | efried | mriedem ... | |
| 14:13:38 | cdent | dansmith: a PUT to /uri means replace resource /uri | |
| 14:14:00 | dansmith | oh sorry I misread, | |
| 14:14:06 | dansmith | you were saying a PUT would imply replacing all | |
| 14:14:08 | dansmith | gotcha | |
| 14:14:08 | efried | mriedem Hmph, I cherry-picked it from gerrit; isn't that supposed to do the -x thing? Will redo. | |
| 14:14:11 | edleafe | cdent: yeah, what dansmith just said. POST is fortunately flexible. | |
| 14:14:12 | cdent | but POST to /uri means create some stuff using whatever semantics you want, and the semantics we want are “create some allocations for the multiple consumers ids we speak here" | |
| 14:14:28 | mriedem | efried: not if the change you're cherry picking from in gerrit isn't merged yet | |
| 14:14:37 | efried | mmkay | |
| 14:14:51 | cdent | efried: I got caught by that the other day and shook my tiny fist | |
| 14:15:22 | efried | mriedem Do you care if it's a new change set? | |
| 14:16:18 | efried | Actually, is the only difference the "(cherry picked from commit 9c7d73195e4fd1c890228e3223106ccf4f13e22b)" line? | |
| 14:17:06 | efried | howzat: https://review.openstack.org/#/c/498463/ | |
| 14:18:29 | efried | (No bot post for stable? (Have I asked that before? (Seems like a reasonable thing to have; should be relatively few, and certainly noteworthy.))) | |
| 14:19:39 | mriedem | efried: patch bot post for stable would be fine, but you'd have to find out where that is configured; it's either in project-config or system-config | |
| 14:20:02 | efried | will dig | |
| 14:22:19 | beagles | moshele, I was going over https://bugs.launchpad.net/os-vif/+bug/1713590 with sean-k-mooney the other day. | |
| 14:22:20 | openstack | Launchpad bug 1713590 in os-vif "Plugging VFs no longer works without a readable phys_switch_id" [Medium,Triaged] | |
| 14:23:58 | beagles | moshele, it seems that ordering of the mechanism_drivers is a new backwards-compatibility-breaking requirement. Is there a use pattern outside of reordering configurations that could workaround the issue of direct ports getting "caught" by the ovs plugging? | |
| 14:25:01 | beagles | moshele, I was also expecting a failed bind to go to the next driver that supported that port type, but this apparently does not happen | |
| 14:25:56 | beagles | moshele, in short... how is this expected to work :) | |
| 14:29:22 | openstackgerrit | Stephen Finucane proposed openstack/nova master: conf: Move 'ipv6' opts to 'network' https://review.openstack.org/499168 | |
| 14:29:29 | efried | mriedem https://review.openstack.org/499167 | |
| 14:31:02 | beagles | sean-k-mooney, same question ^ :) | |
| 14:32:11 | mriedem | oh gantt | |
| 14:37:03 | openstackgerrit | Stephen Finucane proposed openstack/nova master: conf: Remove deprecated 'remap_vbd_dev' option https://review.openstack.org/499172 | |
| 14:38:06 | openstackgerrit | Steve Noyes proposed openstack/nova master: Implement new attach Cinder flow https://review.openstack.org/330285 | |
| 14:44:39 | moshele | beagles: why reordering is not good? | |
| 14:44:59 | beagles | moshele, if somebody upgrades the packages but not the configuration for example | |
| 14:45:47 | beagles | moshele, in the tripleo change for example.. that is just an example. There will be users that will have custom environments and there is good possibility that they will miss the change | |
| 14:46:16 | beagles | moshele, and anybody not using tripleo or other deployment tools may also miss it | |
| 14:47:29 | beagles | moshele, once they upgrade booting new instances may fail or perhaps worse, become OVS offloaded ports when that was not their intention | |
| 14:47:37 | beagles | moshele, or am I misunderstanding the situation | |
| 14:48:15 | gibi | efried: if you are still looking for configuring the gerritbot to send stable notifications then I think here is an example for that https://review.openstack.org/#/c/499175/ | |
| 14:48:43 | moshele | beagles: they failed they won't be ovs offload because you need to put the NIC in a specific mode | |
| 14:48:58 | efried | gibi Thanks! I proposed https://review.openstack.org/499167 | |
| 14:49:35 | beagles | moshele, is there a way to create a port so it forces it be used as SR-IOV only | |
| 14:49:55 | gibi | efried: cool | |
| 14:50:07 | openstackgerrit | Stephen Finucane proposed openstack/nova master: conf: Remove '[conductor] topic' opt https://review.openstack.org/499179 | |
| 14:50:21 | beagles | moshele, that statement also presumes that they want the offload plug path at all | |
| 14:51:12 | moshele | beagles: can you call me on the phone? | |
| 14:51:20 | beagles | moshele, I can try :) | |

| 15:40:21 | openstackgerrit | Matt Riedemann proposed openstack/osc-placement master: Fix the bug link in the readme https://review.openstack.org/499206 | |
| 16:07:32 | melwitt | mdbooth, kashyap: I'd appreciate it if one of you could sanity check a patch of mine where I'm trying to save an updated domain XML after a volume swap https://review.openstack.org/#/c/498983 | |
| 16:07:43 | kashyap | melwitt: Hi | |
| 16:07:51 | kashyap | Will check | |
| 16:08:33 | melwitt | thanks kashyap. the concern on the patch is whether it's correct to read the live config and use it to redefine the domain, or if that has any potential pitfalls | |
| 16:09:14 | kashyap | melwitt: Noted. I'd normally check w/ danpb on the live config thing, but let me see if I can figure it out first :-) | |
| 16:13:30 | stephenfin | mriedem: Is osc-placement something we're supporting? I was going to fix the docs for doc-migration a while back, but there's only one commit and it was 5 months ago | |
| 16:14:17 | melwitt | kashyap: k. I tested the patch locally with devstack and it seemed to work fine, i.e. the instance soft-rebooted successfully and I see the domain in 'virsh list' | |
| 16:14:44 | sdague | stephenfin: I thought mriedem was going to trigger a release | |
| 16:14:48 | sdague | it's not released yet | |
| 16:14:56 | kashyap | melwitt: Good. But just to note -- the blockRebase() API behaviour documented is still true | |
| 16:15:30 | stephenfin | sdague: Oh, maybe that's it. Wonder if the docs need to be fixed at some point so? | |
| 16:16:00 | kashyap | melwitt: Please report your testing there. I'll comment in a few | |
| 16:16:24 | kashyap | melwitt: Ah, you _did_ report | |
