| kashyap | stephenfin: I think you used the change ID in the commit summary because it is not yet merged? | 10:00 |
| stephenfin | kashyap: No. I just wanted something to link back to the original patch for context | 10:01 |
| kashyap | I personally find it strange to see such a large change ID as part of commit summary. How about "Follow-up for "Lookup nic feature by PCI address" patch | 10:01 |
| stephenfin | I could, though the change ID allows you to click through to the original change | 10:02 |
| kashyap | Yeah, I see the value; but recall: we also have to bear in mind the "guy working from the woods" w/ no internet connection :-) - all needed info present w/ no clicking required | 10:03 |
| kashyap | I'd personally put it in the commit body. But I let you decide here. | 10:05 |

| sean-k-mooney | stephenfin: by the way you realise that mypy support ducktyping | 10:27 |
| stephenfin | I do. What's the context? | 10:27 |
| sean-k-mooney | your responce to melwitt about not using mypy in tests | 10:28 |
| sean-k-mooney | so ducktyping would not be an issue | 10:28 |
| sean-k-mooney | mock proably would be | 10:28 |
| stephenfin | It would if the code expects a Instance object and we're passing a dict or a string | 10:28 |
| sean-k-mooney | but if we create a local class and implement the same interface it would pass | 10:28 |
| stephenfin | which we do in placement | 10:28 |
| stephenfin | *places | 10:28 |
| stephenfin | Possibly, but that would be so much work | 10:29 |
| sean-k-mooney | i know | 10:29 |
| sean-k-mooney | i just mean if the thing we pass ducktypes to the real thing it will pass | 10:29 |
| sean-k-mooney | if it does not we proably should not be passing it now :) | 10:29 |
| sean-k-mooney | im hoping we ill graduly stop passing incorrect types in tests | 10:30 |

| mlycka | Hello, would anyone be kind enough to advise me on how one would go about getting a freeze exception for a spec? | 10:44 |
| gibi | mlycka: what is the spec in question? | 10:46 |
| gibi | mlycka: in general we will make decisions about spec freeze exception request on the today's nova meeting | 10:46 |
| mlycka | gibi: https://review.opendev.org/#/c/702810/ | 10:46 |
| mlycka | I was told by a Mr. Yarwood to go ahead and ask for an exception | 10:46 |
| lyarwood | \o ./me waves | 10:48 |
| sean-k-mooney | mlycka: johnthetubaguy still had some concerns about why we are now taking a different approch then was previously apporved | 10:48 |
| gibi | mlycka, lyarwood: does the sync - async problem was resolved in the spec? | 10:48 |
| mlycka | gibi: I think the idea was to treat is as sync for now and see where that gets us. The spec allows for a change later on during implementation. | 10:50 |
| gibi | mlycka: I will add it to the meeting agenda. but we would need johnthetubaguy and Groka to check your answers to their questions as now we have -1s on the patch | 10:51 |
| mlycka | gibi: Right right, thank you. Should I contact them directly or are they likely to be present in the meeting? | 10:52 |
| lyarwood | mlycka: well the os-server-external-events API that you're using is async so I don't see how this could ever be sync tbh | 10:52 |
| sean-k-mooney | that api is not for enduser to invoke | 10:52 |
| sean-k-mooney | its for other services | 10:53 |
| lyarwood | and that's also a valid point that I missed | 10:53 |
| gibi | mlycka: given that it is summer I don't think they will get back to the spec today or tomorrow | 10:53 |
| mlycka | Yeah, I think a separate endpoint is probably the way to go. | 10:53 |
| sean-k-mooney | mlycka: quiesing a vm shoudl be a server action | 10:53 |
| sean-k-mooney | as would undoing it | 10:53 |
| sean-k-mooney | like pause and unpause | 10:54 |
| mlycka | sean-k-mooney: What do you mean? Yeah, it would have to be done by the VM. | 10:54 |
| sean-k-mooney | https://docs.openstack.org/api-ref/compute/#servers-run-an-action-servers-action | 10:54 |
| sean-k-mooney | i mean you should be extending /servers/{server_id}/action | 10:55 |
| mlycka | Okay, that doesn't sound unreasonable. Any objections? | 10:57 |
| *** markvoelker has joined #openstack-nova | 10:57 | |
| *** ratailor has quit IRC | 10:57 | |
| sean-k-mooney | i object to you using the event api :) but other then that no :) | 10:57 |
| mlycka | Sure, makes sense. I won't have the time change the spec today, but I should be able to get to it tomorrow | 10:58 |
| lyarwood | mlycka: would you also be able to start posting code for this? | 10:59 |
| *** ociuhandu has quit IRC | 11:00 | |
| mlycka | lyarwood: I mean, not tomorrow but yeah, by next week I could start producing code. | 11:00 |
| lyarwood | kk | 11:00 |
| *** ociuhandu has joined #openstack-nova | 11:01 | |
| sean-k-mooney | mlycka: by the way the fact you used the service only external events api is proably why peopel assume this is only for use with cinder | 11:03 |
| mlycka | sean-k-mooney: Might be. I think I misunderstood the use of that endpoint when I first found out about it. | 11:04 |
| sean-k-mooney | ya that is why we have the warning https://docs.openstack.org/api-ref/compute/?expanded=add-associate-floating-ip-addfloatingip-action-deprecated-detail#create-external-events-os-server-external-events | 11:04 |

| sean-k-mooney | artom: it just does not mention that the second half is only true | 12:36 |
| artom | Only if cpu_dedicated_set isn't also set | 12:36 |
| sean-k-mooney | if you use vcpu_pin_set | 12:36 |
| sean-k-mooney | correct | 12:36 |
| artom | And what's the point of documenting the old legacy behavior | 12:37 |
| sean-k-mooney | vcpu_pin_set is deprecated not removed and we default to the legacy behavior | 12:37 |
| artom | I suppose | 12:37 |
| artom | Still, stuff is definitely missing | 12:37 |
| sean-k-mooney | stephen can update it when he removes vcpu_pin_set in a few weeks | 12:37 |
| sean-k-mooney | i guess you could update them to make it clear for train and ussuri before that | 12:38 |
| sean-k-mooney | but its not going to be very useful on master since it wont matter when victoria is released | 12:39 |
| artom | True | 12:43 |

| suryasingh | Hello Team | 15:12 |
| suryasingh | Sorry to interrupt in middle of your work. | 15:12 |
| suryasingh | I have a query about downsizing the nova instance. | 15:12 |
| suryasingh | When I downsize with —poll status comes out to be Finished. But confirming the the same fails with below error. | 15:12 |
| suryasingh | ERROR (Conflict): Cannot 'confirmResize' instance eaff75ba-1e16-4096-8882-33028d8b97fd while it is in vm_state active (HTTP 409) (Request-ID: req-71f53b9c-d01d-4bfe-a22c-b62401545f3c) | 15:12 |
| suryasingh | So I just wanted to confirm, if it’s feasible operation from nova side and if not, is there any historical reason of it to not support downsize operation ? | 15:12 |

| suryasingh | melwitt: dansmith lyarwood gmann efried would be very thankful if any of you respond to my query. | 15:26 |
| gibi | suryasingh: do you try to downsize the disk in the flavor? | 15:27 |
| suryasingh | @gibi whole flavor including disk. | 15:27 |
| lyarwood | yeah I didn't think we supported down sizing tbh | 15:28 |
| lyarwood | we can't downsize the disk at least | 15:28 |
| *** jangutter_ has joined #openstack-nova | 15:28 | |
| gibi | the resize action fails if you try to decrease the disk size with 'Resize error: Unable to resize disk down.' | 15:28 |
| gibi | the cpu and memory can be downsized | 15:28 |
| sean-k-mooney | you can downsize the ram or cpus | 15:29 |
| sean-k-mooney | but not the disk | 15:29 |
| sean-k-mooney | as that would loose data potentially | 15:29 |
| sean-k-mooney | oh gibi just said that | 15:29 |
| * gibi even tried that! :) | 15:30 | |
| suryasingh | gibi: sean-k-mooney lyarwood understood. Thanks for responding to query. | 15:30 |

| stephenfin | Does anyone care to sanity check this idea for me? I end up wanting the feature every time I have to use osc-placement (along with auto-translation of RP names to UUIDs, but that's more work) https://review.opendev.org/#/c/743976/ | 15:37 |
| stephenfin | As an aside, there are a quite a few patches queued up for review at https://review.opendev.org/#/q/is:open+project:openstack/osc-placement | 15:38 |

| sean-k-mooney | gibi: i the neutron docs are confusing on the ip allocation policy. i think i saw one place refecne that neutorn would do it automaticlly but i know when it was first added it needed to be set manually | 16:09 |
| gibi | sean-k-mooney: I don't have my mutlisegment test env working so I cannot check right now but as far as I remember I had to set it manually | 16:10 |

| sean-k-mooney | ok nova does not actully support multisegment prodier netwroks correctly | 16:12 |
| sean-k-mooney | if you try to use them it will fail in at least two cases | 16:12 |
| sean-k-mooney | sriov | 16:12 |
| sean-k-mooney | and if one host has 2 phsynets it wont work right | 16:13 |
| sean-k-mooney | also numa_aware_vswitch or anything that depens on the phsynet wont work properly | 16:13 |
| sean-k-mooney | but ya that as seperate problem | 16:13 |
| gibi | I guess I never tried with two physnets then | 16:15 |
| *** nightmare_unreal has quit IRC | 16:16 | |
| *** hamalq has joined #openstack-nova | 16:17 | |
| sean-k-mooney | gibi: we just grap the first physnet form the list in nova | 16:17 |
| sean-k-mooney | so if a network has more then one phsynet then there is no guarenttee that it will be correct. | 16:18 |
| sean-k-mooney | the current hack that existsi assuem that we will have at most 1 provider network and 1 tunnel network but not multipele provider networks | 16:19 |
| *** hamalq has quit IRC | 16:19 | |
| *** hamalq has joined #openstack-nova | 16:20 | |
| gibi | would it make sense to have two provide segment in the same network? | 16:23 |
| *** dougsz has quit IRC | 16:29 | |
| sean-k-mooney | yes that is what the routed provider netwrok feature in neturon is for | 16:40 |
| sean-k-mooney | it uses physnets to map hosts to segments | 16:40 |
| sean-k-mooney | there is no other way to map host to segments that i have found | 16:40 |

| sean-k-mooney | lyarwood: yes they are | 18:55 |
| sean-k-mooney | they are generated by libvirt | 18:55 |
| lyarwood | wonderful | 18:55 |
| sean-k-mooney | with one per numa node | 18:55 |
| sean-k-mooney | the are in the instance directory | 18:56 |

| sean-k-mooney | thats one per guest numa node by the way | 18:56 |
| lyarwood | oh no reason | 18:56 |

| artom | stephenfin, so you're saying you'll edit out the typing stuff when you backport https://review.opendev.org/#/c/744958/ ? | 19:14 |
| artom | I mean, I'd have done it right away by doing 2 patches, but w/e works | 19:14 |
| stephenfin | artom: Yup, though only because I have to for Train (it's not Python 3-only) | 19:16 |
| stephenfin | If it was, I'd leave them since they're a noop until mypy is enabled for that file (via mypy-files.txt) | 19:16 |
| artom | stephenfin, ack, I'll remove my -1 then. I still don't fully get the problem/fix though :P | 19:17 |
| stephenfin | a second patch is also doable, but I find the type hints help understand what's getting passed around | 19:17 |
| stephenfin | I'm replying with that now | 19:17 |
| artom | Yeah, I can understand that (the typing hints helping) | 19:17 |
| stephenfin | artom: comments left. Let me know if that makes sense | 19:19 |
| *** tosky has quit IRC | 19:20 | |
| artom | stephenfin, ah, I think I get it - we don't "delta" the usage, we rebuild it from scratch every time. So if a certain migration/instance doesn't get counted as "tracked", it'll effectively unpin its PCPUs | 19:20 |
| stephenfin | Yup, exactly | 19:21 |
| artom | OK, great, so that's 1 hour to understand the concept. | 19:21 |
| artom | Now to review the actual code :P | 19:21 |
| artom | Need to pick up food first though | 19:22 |
| stephenfin | TBH, that whole periodic task feels racy and generally wrong to me, but it does state that it's intention is to blow everything away and start from scratch so... | 19:22 |
| stephenfin | yet another thing to add my "tech debt I really need to get back to" list, I guess | 19:22 |
| artom | It's definitely not the first race in there | 19:23 |
| artom | See: https://review.opendev.org/#/c/684409/ | 19:23 |
| stephenfin | For sure. I decided not to start listing the related bugs of the related bugs, because it started getting ridiculous | 19:23 |
| stephenfin | concurrency is hard | 19:24 |
| artom | Yeah, chill with that, you trying to one-up George RR Martin or something? | 19:24 |
| stephenfin | Try to write an explanation for https://review.opendev.org/744021 (with other nova devs that don't have this specific libvirt CPU pinning knowledge in mind) and let me know how you get on :P | 19:26 |
| * stephenfin goes back to soldering stuff | 19:29 | |
| sean-k-mooney | stephenfin: speaking about racy periodics | 19:44 |
| sean-k-mooney | its possible that we have a race between them starting in general on inital boot and the compute agent looking up it compute node uuid or maybe even creating the compute node record | 19:45 |
| sean-k-mooney | i say its posible becuase im expecting a bug to be filed for http://pastebin.test.redhat.com/891237 | 19:46 |
| sean-k-mooney | and that is my working theory on how we could be trying to update a compute node recored with a compute_node_id of none | 19:47 |
| sean-k-mooney | oh but that one does not have have startup set.... | 19:49 |
| sean-k-mooney | https://github.com/openstack/nova/blob/9ecefeb836964c52a5a2969b15c82b11c51d32ab/nova/compute/manager.py#L9723 | 19:49 |
