| 12:57:13 | sean-k-mooney | we must know the path before we start the vm since we need to specify the path in the vm xml | |
| 12:57:22 | brinzhang | right | |
| 12:58:05 | sean-k-mooney | and we cannot copy any data untile we have claimed the devcie because other wise we coudl race with a differnte vm and that could be a security bug or at least a data loss bug | |
| 12:59:55 | brinzhang | yes, if it's right we will lost the datas in pmem | |
| 13:00:24 | brinzhang | I will check the prep_resize tomorrow | |
| 13:01:51 | brinzhang | may it need to claim the pci devices in resource tracker | |
| 13:02:33 | sean-k-mooney | im currenlty trying to figure out why it does not appear to be doign that although i may have missed it | |
| 13:02:40 | sean-k-mooney | i tought it was doing that already | |
| 13:03:09 | sean-k-mooney | but yes when we aquire the instnace clam or move claim it should for cold migration at least | |
| 13:03:27 | sean-k-mooney | for live migration we explitly claim the neutron pci devices in the pci tracker | |
| 13:03:39 | sean-k-mooney | we do not use move claims for that | |
| 13:04:06 | sean-k-mooney | for pmems though you will need to cliam them in the resouce table in the db | |
| 13:05:28 | brinzhang | yes, we shuold claims it firstly before cold migrate the instance | |
| 13:07:54 | sean-k-mooney | yep because we want to abort the migration if we cant claim | |
| 13:08:34 | sean-k-mooney | this is why we insited the spec be written the way it currently is | |
| 13:12:52 | sean-k-mooney | brinzhang: the poc wont work by the way | |
| 13:13:10 | sean-k-mooney | brinzhang: ill push comments in a second but its using processutiles incorrectly | |
| 13:13:45 | sean-k-mooney | https://review.opendev.org/c/openstack/nova/+/802225/1/nova/virt/libvirt/driver.py#10757 | |
| 13:13:50 | brinzhang | it's ok, I agree your point, and I think firstly we should claim the pmem devices in prep_resize interface, and then check it when we want to execute migrage_server then to copy date form source pmem to the target pmem devices | |
| 13:14:31 | sean-k-mooney | well if the claim fails then the migration shoudl go to error and the vm will stay in active | |
| 13:15:08 | opendevreview | Pavlo Shchelokovskyy proposed openstack/nova stable/queens: libvirt: Skip encryption metadata lookups if secret already exists on host https://review.opendev.org/c/openstack/nova/+/765774 | |
| 13:16:31 | brinzhang | sean-k-mooney:ok, hope you can review if you find the error in that patch, we will update and try to update in next patch | |
| 13:19:41 | sean-k-mooney | the issue is the 3 commands in _migrate_vpmem_data will all execute on the same host. to fix it you need to pipe the output of the first commadn into the input of the second and the second and third commands should be combined | |
| 13:21:07 | brinzhang | agree, I saw your comment, it's useful to improve efficiency | |
| 13:28:02 | sean-k-mooney | well it wont work the way it is now | |
| 13:28:58 | sean-k-mooney | it might work on the same host but both daxio command woudl execute on the local host | |
| 13:32:13 | brinzhang | ack, it should be update, in local we have tested the CLI, it works fine | |
| 13:33:09 | sean-k-mooney | if you use those comand on the cli it would wokr but only because the second comamdn will put you in a new shell on the dest | |
| 13:33:34 | sean-k-mooney | to emulate this on the cli you need to rune each exec in a new terminal | |
| 13:33:58 | brinzhang | ack | |

| 16:03:14 | bauzas | any other bugs people wanna raise ? | |
| 16:03:46 | stephenfin | nope, we had a gate issue due to Sphinx 4.x but sean-k-mooney fixed that for us | |
| 16:04:11 | bauzas | we could have had a cinderclient bug, but the v3 change is now merged, right? | |
| 16:04:22 | bauzas | stephenfin: excellent, thanks sean-k-mooney | |
| 16:04:22 | sean-k-mooney | ya i think that is merged now | |
| 16:04:28 | stephenfin | Yes, the nova one landed last week and the novaclient one went in earlier today | |
| 16:04:41 | bauzas | oki doki | |
| 16:04:58 | sean-k-mooney | https://review.opendev.org/c/openstack/nova/+/802334 | |
| 16:04:59 | bauzas | were we limiting the cinderclient version ? | |
| 16:05:02 | sean-k-mooney | that was the nova one | |
| 16:05:15 | sean-k-mooney | bauzas: no we jsut had a refernce to v2 | |
| 16:05:22 | bauzas | ok | |
| 16:05:28 | sean-k-mooney | replced it with v3 | |
| 16:05:28 | bauzas | anyway, moving | |

| 16:06:33 | bauzas | #topic Gate status | |
| 16:07:02 | bauzas | meh, maybe the meetbot works with the #topic section | |
| 16:07:03 | bauzas | anyway | |
| 16:07:14 | bauzas | nothing to say about any gate issue ? | |
| 16:07:40 | stephenfin | nope, not beyond the above | |
| 16:07:42 | bauzas | I can see a new one from lyarwood https://bugs.launchpad.net/nova/+bug/1938021 | |
| 16:08:13 | sean-k-mooney | we are still using the tempoary workaround for the ovsdb issue. ill try and find out how the ovs change is comming before m3 but no other update on that | |
| 16:08:45 | sean-k-mooney | hum interesting | |
| 16:08:52 | melwitt | I have noticed while working on placement consumer types that a generation conflict gets hit on my patches, let me find the (old) gate bug | |
| 16:08:53 | sean-k-mooney | was tehre a new olo release | |
| 16:09:24 | bauzas | sean-k-mooney: good question | |
| 16:09:37 | melwitt | this one http://bugs.launchpad.net/bugs/1836754 | |
| 16:10:20 | sean-k-mooney | bauzas: the messging issue might be related to something moving and we are nolonger mocking properly in the func tests | |
| 16:10:43 | bauzas | melwitt: heh, who is working on this one ? | |
| 16:10:46 | melwitt | it occurs in general too but while working on placement to do more during a PUT it makes it happen a lot more. so a heads up that I think we'll need to address that before placement consumer types will be usable | |
| 16:10:48 | sean-k-mooney | although perhaps not it is corectly using the fake implementation. | |
| 16:11:09 | bauzas | melwitt: oh it's you | |
| 16:11:21 | sean-k-mooney | huh i could see that conflict happening alright | |
| 16:11:39 | melwitt | bauzas: I have restored mriedem's old patch about the bug and will add tests to it for review | |
| 16:11:47 | bauzas | do we have race conditions for this a lot ? (the conflict) | |
| 16:11:55 | melwitt | yeah, it was originallly from tssurya and cdent but both moved off of openstack before it was finished so I've been working on finishing it | |
| 16:12:06 | bauzas | or is it just for a few job runs ? | |
| 16:12:37 | melwitt | bauzas: I have seen it on other patches yes, but not nearly as often as I do on the placement patches. on the placement patches it looks pretty much guaranteed | |
