| 09:06:27 | Spaz-Work | Morning folks | |
| 09:07:37 | gibi | happy Friday morning Nova | |
| 09:21:21 | stephenfin | zigo: Could you report that as bug, if you haven't done so already? | |
| 09:21:40 | openstackgerrit | Zhenyu Zheng proposed openstack/nova master: nova-manage db archive_deleted_rows is not multi-cell aware https://review.openstack.org/507486 | |
| 09:22:20 | openstackgerrit | Stephen Finucane proposed openstack/nova master: Add CPUWeigher https://review.openstack.org/379525 | |
| 09:24:33 | stephenfin | bauzas, giblet: morning folks. Any chance one of you could look at these two patches? https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:cleanup | |
| 09:24:48 | bauzas | zigo: sorry, my laptop thinks it's already the week-end and suddently shutdowns | |
| 09:25:08 | bauwser | good lord, it's Friday | |
| 09:25:09 | Spaz-Work | man this script is jenky | |
| 09:25:33 | Spaz-Work | Casual Nick Friday? | |
| 09:25:34 | Spaz-Work | :D | |
| 09:25:49 | finucannot | You know it :) | |
| 09:26:16 | Spaz-Work | And they say the core's don't know how to have fun | |
| 09:26:44 | Spaz-Work | .replace('\'','') | |
| 09:27:20 | finucannot | Those people are wrong, and in my 100 slide presentation I will proceed to show exactly how they are wrong | |
| 09:27:53 | bauwser | finucannot: CPUWeigher, good lord | |
| 09:28:11 | Spaz-Work | How much does a CPU Weigh? Now we'll know. | |
| 09:28:15 | finucannot | bauwser: I'm still getting pinged on Bugzilla for it :( | |
| 09:28:28 | bauwser | you know that I'm not a super fan of having moar weighers, right ;) | |
| 09:28:43 | finucannot | It's my oldest still-open review, by far | |
| 09:28:46 | bauwser | given anyone can add anything they want | |
| 09:29:05 | finucannot | bauwser: Aye, but who'll support it? ;) | |
| 09:29:47 | Spaz-Work | That actually reminds me there was a bug opened recently about scheduler I need to find | |
| 09:29:49 | bauwser | finucannot: the customer itself | |
| 09:30:10 | Spaz-Work | I was looking into it but scheduler has this really wierd ABC method that I don't understand... | |
| 09:30:27 | bauwser | we can provide a sane framework for end customers of the scheduler that could add anything they'd like | |
| 09:31:01 | openstackgerrit | huanhongda proposed openstack/nova master: Enable panic device https://review.openstack.org/551224 | |
| 09:31:29 | Spaz-Work | Ah yeah here it is | |
| 09:35:04 | zigo | finucannot: Will report it, yeah. | |
| 09:35:22 | zigo | Though I wonder if it's a py3 issue, or just that the simple_cell_setup just failed on me. | |
| 09:35:51 | finucannot | zigo: Aye, it could be that too. There's definitely at least one issue there though | |
| 09:35:55 | zigo | What is this, and how to get it silent too? | |
| 09:35:59 | zigo | exception.NotSupportedWarning | |
| 09:35:59 | zigo | /usr/lib/python3/dist-packages/oslo_db/sqlalchemy/enginefacade.py:332: NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported | |
| 09:36:26 | finucannot | zigo: DevStack? | |
| 09:36:42 | zigo | finucannot: No, Debian Stretch with Queens ! :) | |
| 09:37:01 | zigo | finucannot: That's the last bits in getting all packages setup before I can run my functional tests. | |
| 09:38:00 | zigo | Let me cut-past the output of simple_cell_setup before I fill the bug. | |
| 09:38:13 | zigo | It fails because there's some missing tables, apparently. | |
| 09:38:20 | finucannot | zigo: Cool. Can you use paste.openstack.org though | |
| 09:38:33 | zigo | Sure. | |
| 09:38:33 | finucannot | (rather than posting here) | |
| 09:39:03 | Spaz-Work | Anyone happen to have a map of how the select_destinations codebase works in nova-scheduler? | |
| 09:39:09 | Spaz-Work | I've run into circles about 13 trimes now | |
| 09:40:00 | openstackgerrit | Zhenyu Zheng proposed openstack/nova-specs master: Add host field to instance action event https://review.openstack.org/550411 | |
| 09:41:32 | Spaz-Work | Ah I think I see.. filter_scheduler is what is extending that.. couldn't find what was using it the abstract | |
| 09:42:05 | zigo | finucannot: http://paste.openstack.org/show/696053/ | |
| 09:43:02 | zigo | I really would like to understand better the db thing for cells, does it uses the db of nova, or nova-api, or something else? | |
| 09:43:19 | zigo | What am I supposed to setup? Is there a db-sync somewhere for the cells? | |
| 09:44:51 | zigo | Which of cell0 and cell1 needs a db? Both? With different dbs? | |
| 09:45:01 | zigo | Should they both access rabbit? | |
| 09:48:38 | finucannot | zigo: I think there's should be separate message queue per cell, plus a top-level API one | |
| 09:49:15 | zigo | finucannot: Even in my simple single node setup for package validation? | |
| 09:49:15 | finucannot | They _could_ use the same RabbitMQ instance (is that the correct term?) but it should be some form of logical split nonetheless | |
| 09:49:41 | zigo | Ah, right, like a different rabbit vhost or something... | |
| 09:49:48 | zigo | That's doable. | |
| 09:50:06 | finucannot | I can't say, to be honest. Anything I know about cells v2 was gleaned from a talk dansmith gave in...Sydney? | |
| 09:50:14 | finucannot | vhost...yeah, that sounds familiar | |
| 09:50:32 | zigo | What they call vhost in rabbit is a kind of path. | |
| 09:50:41 | zigo | Like / or /cell0 ... | |
| 09:51:10 | finucannot | zigo: https://www.youtube.com/watch?v=o7jkqzORij8 | |
| 09:51:22 | finucannot | We _surely_ have this in written form somewhere, but lord knows where | |
| 09:51:44 | bauwser | finucannot: zigo: you need to have separate MQs for cells vs. API, but both can be on the same broker | |
| 09:51:57 | bauwser | for AIO at least | |
| 09:52:18 | zigo | Ok. | |
| 09:52:19 | bauwser | https://docs.openstack.org/nova/latest/user/cellsv2-layout.html | |
| 09:52:22 | bauwser | finucannot: ^ | |
| 09:52:25 | finucannot | zigo: This looks somewhere helpful https://docs.openstack.org/nova/latest/user/cellsv2-layout.html Three databases, as suspected | |
| 09:52:31 | finucannot | bauwser: Jinx :) | |
| 09:52:32 | bauwser | jinx ! | |
| 09:53:06 | zigo | I'll read all of this, and will come back here if I don't get it, thanks guys, that's very helpful. | |
| 09:53:11 | bauwser | np | |
| 09:53:17 | bauwser | and sorry for being AWOL | |
| 09:53:31 | bauwser | thank ABRT signal | |
| 09:54:14 | bauwser | looks something is tainting my kernel so it sens the abrt signal | |
| 09:54:16 | zigo | bauwser: Switch to Debian ! :) | |
| 09:54:25 | bauwser | *cough cough* | |
| 09:54:45 | bauwser | I was running Ubuntu before, but I feel somehow corporate | |
| 09:55:03 | bauwser | although I have nothing preventing me to install any other distro | |
| 09:55:28 | bauwser | and tbh, I'm pretty happy with F27, works like a charm | |
| 10:02:02 | Spaz-Work | I may go back to Fedora next time | |
| 10:02:10 | Spaz-Work | It's been a long journey and i'm ready to come home and brick after updates | |
| 10:02:17 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Replace raise with self.fail() in unit test https://review.openstack.org/550914 | |
| 10:02:40 | Spaz-Work | scheduler you make my head hurt.. but imma learn you. | |
| 10:03:30 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Raise a proper exception in unit test https://review.openstack.org/550914 | |
| 10:26:21 | zigo | finucannot: bauwser: All of this doc and talk doesn't answer the practical questions: how do I setup my all-in-one-server setup, how do I db-sync the cell0 and cell1 dbs. | |
| 10:26:38 | zigo | And how can I make multiple conductors access to different rabbitmq vhosts ... | |
| 10:26:50 | zigo | They'd be sharing the same nova.conf... | |
| 10:27:07 | lyaaaaaaaarwood | ratailor: re https://review.openstack.org/#/c/401009 one nit and a quick comment based on the initial .save() in that method. | |
| 10:27:28 | bauwser | zigo: devstack can help | |
| 10:27:44 | zigo | bauwser: How can it help me doing that setup with packages? | |
| 10:27:55 | zigo | Do you mean, i should read devstack's scripts? | |
| 10:27:59 | bauwser | by looking on how it's setup | |
| 10:28:00 | bauwser | yeah | |
| 10:28:03 | zigo | k | |
| 10:28:23 | finucannot | It's a horrible answer, but yeah. It's that or use some other tool to install this stuff :( | |
| 10:28:56 | finucannot | I will note that DevStack configures multiple nova.conf files. nova.conf, nova-cpu.conf, nova_cell1.conf, ... | |
| 10:28:56 | zigo | bauwser: finucannot: Should I attempt to just implement this on my single server setup? https://docs.openstack.org/nova/latest/_images/graphviz-609e99b08abf22927d47c939873591359f7e50e3.png | |
| 10:29:27 | zigo | (ie: single conductor, 1 db for each of cell0 and cell1) | |
| 10:30:10 | bauwser | zigo: finucannot: AFAIK, we pass the transport_url when we create the cell as a parameter | |
