| xyang1 | Hi | 16:01 |
| ildikov | hi all :) | 16:01 |
| _pewp_ | hemna ヾ(-_-;) | 16:01 |

| *** mgiles has joined #openstack-meeting-cp | 16:02 | |
| mriedem | o. | 16:02 |
| ildikov | ok, let's start | 16:03 |
| smcginnis | o/ | 16:03 |
| ildikov | so the big news since last week is that the uWSGI modifications broke the microversion check in the cinderclient | 16:03 |
| *** eeiden is now known as eeiden_ | 16:03 | |
| ildikov | which means that all the gate jobs that try to use the new attach flow blow up when we check whether 3.27 is available or not | 16:04 |
| hemna | neat | 16:04 |
| *** eeiden_ is now known as eeiden | 16:04 | |
| ildikov | mriedem: if you have any uWSGI suggestions for us, that would be great :) | 16:04 |
| mriedem | because the version discovery breaks? | 16:04 |
| mriedem | andreykurilin fixed something like that in novaclient, sec | 16:05 |
| ildikov | I reported a bug for this yesterday: https://bugs.launchpad.net/devstack/+bug/1708188 | 16:05 |
| openstack | Launchpad bug 1708188 in python-cinderclient "get_highest_client_server_version is failing with the new uWSGI changes in Devstack" [Undecided,New] | 16:05 |
| mriedem | https://github.com/openstack/python-novaclient/commit/bd0a2adefe5e89c4269f6589837f871764c6f1f6 | 16:05 |
| ildikov | devstack patch: https://review.openstack.org/#/c/489715/ | 16:05 |
| ildikov | cinderclient patch: https://review.openstack.org/#/c/490040/ | 16:05 |
| smcginnis | mriedem: That looks like the same issue we're having. | 16:06 |
| * smcginnis was really hoping it wasn't something that required a client update... | 16:06 | |
| ildikov | mriedem: coolio, thanks | 16:06 |
| ildikov | mriedem: I was looking for something like that :) | 16:06 |
| ildikov | I will point e0ne to that novaclient fix | 16:07 |
| *** david-lyle has joined #openstack-meeting-cp | 16:07 | |
| smcginnis | ildikov: Looks like he's not online or I was going to do that right now. | 16:07 |
| mriedem | i already put it in the cinderclient wip | 16:07 |
| smcginnis | mriedem: Thanks | 16:07 |
| ildikov | mriedem: awesome, thanks | 16:08 |
| mriedem | so community goal for pike is cinder api in uwsgi, | 16:08 |
| mriedem | but doing that breaks cinderclient version discovery, which is needed for version negotiation with the v3 api yes? | 16:08 |
| smcginnis | Yep, it appears so | 16:08 |
| mriedem | so wouldn't fixing that in cinderclient require a fix and release for pike? | 16:08 |
| mriedem | post-freeze i mean | 16:08 |
| mriedem | doesn't mean anything to nova really since the patches that rely on it wont be in pike, but just thinking about timelines and process | 16:09 |
| smcginnis | Yes. We're well into freeze, so I don't think we can fix until unfreeze. | 16:09 |
| mriedem | i guess you could backport the fix later | 16:09 |
| mriedem | and release from stable/pke | 16:09 |
| mriedem | *pike | 16:09 |
| smcginnis | But we can do a stable release right away when it opens up. | 16:09 |
| ildikov | mriedem: I guess for backward compatibility it would be great if it does not blow up | 16:09 |
| ildikov | I guess we can handle random errors from the cinderclient | 16:09 |
| smcginnis | We just can't raise the g-r minimum, so no guarantee that the fixed client is in use in Pike. | 16:09 |
| smcginnis | So worse case - this fails and negotiates back to legacy attach, right? | 16:10 |
| ildikov | smcginnis: yes | 16:10 |
| smcginnis | So the world isn't blowing up, but the kitchen is on fire. | 16:11 |
| smcginnis | SO normal state. | 16:11 |
| jgriffith | smcginnis :) | 16:11 |
| ildikov | I can catch the ValueError that it throws and fall back | 16:11 |
| * jungleboyj hands smcginnis a fire extinguisher | 16:12 | |
| ildikov | but honestly I would not like to have too many of those there as then we will silently fall back to the old flow for various reasons in the future that we might not catch | 16:12 |
| ildikov | and we need to fix it quickly so we can finally move forward with the attach patch | 16:12 |
| ildikov | for which I have clean test runs locally | 16:12 |
| smcginnis | ++ | 16:13 |
| ildikov | with the blockdev error still in the periodic task | 16:13 |
| ildikov | I didn't see anything else failing in the tempest runs, but I have an overly patched env right now... | 16:14 |
| ildikov | jgriffith: do you have any additions to this? | 16:14 |
| jgriffith | too much to even go into | 16:14 |
| jgriffith | runs are extremely inconsistent right now which is worrisome | 16:15 |
| jgriffith | and not just around attach/detach | 16:15 |
| jgriffith | random failures.. as smcginnis mentioned "SO normal state" | 16:15 |
| smcginnis | :) | 16:15 |
| jgriffith | It does seem as though it's a race somewhere; running tests serially seems "ok" most of the time | 16:15 |
| ildikov | does not sound good | 16:17 |
| jgriffith | ildikov meh... nothing earth shatteringly new | 16:17 |
| ildikov | true :) | 16:17 |
| jgriffith | I'm optimistic that I'll figure it out :) | 16:17 |
| * ildikov puts on her optimistic hat too then :) | 16:18 | |
| ildikov | ok, I don't think we have enough info to talk about this more here | 16:18 |
| ildikov | jgriffith: or do you have anything else to add? | 16:18 |
| jgriffith | ildikov nope | 16:18 |
| ildikov | ok | 16:18 |
| ildikov | stvnoyes: the two patches posted in the cinderclient bug report are fixing things in a Devstack env if you would need to run tests locally | 16:19 |
| stvnoyes | ok thx | 16:19 |
| ildikov | stvnoyes: anything in your tempest test or for live migrate to talk about here? | 16:20 |
| stvnoyes | no, it would be great to get a review but I understand that's pretty far down the priority list for now | 16:20 |
| stvnoyes | before I forget what I did | 16:21 |
| ildikov | sounds reasonable | 16:21 |
| ildikov | as we hope to get this fixed and merged before the PTG I hope we can fix the version check in the cinderclient soon so you get clean test runs on the gate for your part | 16:22 |
| stvnoyes | that would be great | 16:22 |
| ildikov | smcginnis: keep in touch about the client release when the issue is fixed there | 16:22 |
| ildikov | anything else from anyone for today? | 16:22 |
| stvnoyes | not for me | 16:22 |
| ildikov | alright, then that's it for today | 16:23 |
| smcginnis | Thanks | 16:23 |
| ildikov | mriedem: thanks again for the pointer | 16:24 |
| ildikov | have a good day everyone! | 16:24 |
