| 21:37:51 | dansmith | o/* | |
| 21:37:55 | mriedem | o/. | |
| 21:38:08 | melwitt | .\o | |
| 21:38:10 | mriedem | i'm just going to steal the classics from melwitt | |
| 21:38:13 | jroll | o/' | |
| 21:38:17 | dtp | armpit bump? | |
| 21:38:18 | jroll | cheeeeeers | |
| 21:38:20 | dansmith | ~~.\o/.~~ | |
| 21:38:24 | melwitt | lol | |
| 21:38:25 | mriedem | odor lines? | |
| 21:38:30 | dansmith | smell lines yeah | |
| 21:38:32 | mriedem | ha | |
| 21:38:50 | dansmith | I am in portland after all, where showers are optional | |
| 21:39:56 | dtp | ok mriedem, reading now | |
| 21:46:51 | dtp | what does the services table contain? | |
| 21:47:27 | mriedem | services | |
| 21:47:34 | dtp | hehe | |
| 21:47:45 | dtp | like . . . keystone? | |
| 21:47:50 | mriedem | no | |
| 21:47:54 | mriedem | info about the actual nova services | |
| 21:47:59 | mriedem | like nova-compute, nova-scheduler, etc | |
| 21:48:03 | mriedem | the host/binary/topic fields | |
| 21:48:05 | mriedem | service versoin | |
| 21:48:06 | mriedem | enabled/disabled | |
| 21:48:07 | mriedem | et | |
| 21:48:08 | mriedem | *etc | |
| 21:48:16 | mriedem | https://developer.openstack.org/api-ref/compute/#compute-services-os-services | |
| 21:48:20 | dtp | ah. thank you | |
| 21:48:30 | mriedem | heh "Lists all running Compute services for a tenant," that's wrong | |
| 21:48:34 | mriedem | services are not per-tenant | |
| 21:48:40 | mriedem | sdague: more api-ref fun ^ | |
| 21:49:04 | mriedem | that should be "for a region" right? | |
| 21:49:11 | mriedem | or a cell i guess | |
| 21:49:28 | mriedem | but i'm not sure we want to start using the c word in the api ref yet | |
| 21:49:29 | dansmith | not a cell | |
| 21:49:34 | dansmith | yeah, don't say that | |
| 21:49:35 | mriedem | true, | |
| 21:49:39 | mriedem | api isn't in the cell | |
| 21:49:42 | dansmith | say for a deployment or region or something | |
| 21:49:45 | mriedem | yeah | |
| 21:50:39 | melwitt | dtp: to see how it's used, look at nova/db/sqlalchemy/models.py at Service to see the data model, then look at nova/objects/service.py to see the object API and you can sort of trace how it's used from using that as a starting point. also look at nova/service.py | |
| 21:51:40 | dtp | ok, thanks | |
| 21:51:52 | mriedem | dansmith: guh, we need to update this at some point too https://docs.openstack.org/ops-guide/arch-scaling.html#cells-and-regions | |
| 21:52:45 | dansmith | hmm, yeah | |
| 21:58:41 | openstack | Launchpad bug 1673616 in openstack-manuals "Scaling in Operations Guide - cells section needs to be updated" [Undecided,New] | |
| 21:58:41 | mriedem | dansmith: i've opened a docs bug https://bugs.launchpad.net/openstack-manuals/+bug/1673616 | |
| 21:58:51 | mriedem | dansmith: you might want to add/update/fix whatever i put in the description | |
| 22:00:12 | dansmith | okay | |
| 22:00:29 | dansmith | looks alright to me at first skim but I'll think on it a bit | |
| 22:01:15 | openstackgerrit | Matt Riedemann proposed openstack/nova master: api-ref: fix description in os-services https://review.openstack.org/446757 | |
| 22:18:05 | openstackgerrit | melanie witt proposed openstack/nova master: Improve descriptions for hostId, host, and hypervisor_hostname https://review.openstack.org/446761 | |
| 22:18:37 | melwitt | mriedem: ^ patch for the host* api-ref stuff | |
| 22:26:39 | openstackgerrit | Octave Orgeron proposed openstack/nova-specs master: Enables MySQL Cluster Support for Nova https://review.openstack.org/446631 | |
| 22:33:55 | mriedem | melwitt: thanks, comments inline | |
| 22:45:56 | cfriesen | is there a known issue in newton where pre_live_migration() can hit an RPC timeout waiting for a really big glance image to download to the destination? | |
| 22:56:52 | openstackgerrit | OpenStack Proposal Bot proposed openstack/nova master: Updated from global requirements https://review.openstack.org/446777 | |
| 23:10:52 | openstack | Launchpad bug 1673628 in OpenStack Compute (nova) "api-ref: 'tags' field is not in response parameters docs for "GET /servers/{server_id}"" [Medium,Confirmed] | |
| 23:10:52 | mriedem | easy bug fix https://bugs.launchpad.net/nova/+bug/1673628 | |
| 23:11:07 | mriedem | cfriesen: that's not a newton specific limitation | |
| 23:11:15 | mriedem | that's a latent issue forever | |
| 23:11:41 | mriedem | cfriesen: see https://review.openstack.org/#/c/419662/1 | |
| 23:13:36 | openstackgerrit | Matt Riedemann proposed openstack/nova-specs master: Repropose tag-instance-when-boot https://review.openstack.org/415315 | |
| 23:13:45 | mriedem | Kevin_Zheng: are you ok with the updates i made to ^? | |
| 23:18:20 | mriedem | melwitt: i think your func test change might be causing a race issue with global state | |
| 23:20:01 | mriedem | yeah you need to use fake.restore_nodes | |
| 23:24:09 | sbezverk | hello, I need to check liveness of nova placement api process, could you recommen any methods to check not just that the socket is opened but also that the process is alive and sane. | |
| 23:24:26 | mriedem | sbezverk: make a curl request to / ? | |
| 23:24:54 | mriedem | that's testing much more than just the process is running | |
| 23:25:01 | sbezverk | mriedem: would it not just check apachie liveness? | |
| 23:25:28 | mriedem | making a curl request to the actual endpoint's root would provide the versions available, which means it's up and running and accepting requests | |
| 23:25:31 | mriedem | and serving a response | |
| 23:25:51 | mriedem | i don't know if a token is required for GET / on the placement endpoint though | |
| 23:26:22 | sbezverk | mriedem: cool, thank you very much. I was not sure if curling for root is sufficient | |
| 23:26:53 | mriedem | yup that will get you the versions available | |
| 23:39:19 | openstackgerrit | Ghanshyam Mann proposed openstack/nova master: Add api-ref for filter/sort whitelist https://review.openstack.org/421760 | |
| 23:39:52 | sbezverk | mriedem: any known issue with placement in ocata you are aware? | |
| 23:39:55 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Fix functional regression/recreate test for bug 1671648 https://review.openstack.org/446685 | |
| 23:39:56 | openstack | bug 1671648 in OpenStack Compute (nova) ocata "Instances are not rescheduled after deploy fails" [High,In progress] https://launchpad.net/bugs/1671648 - Assigned to Matt Riedemann (mriedem) | |
| 23:40:21 | mriedem | sbezverk: nothing major for placement that i can think of | |
| 23:40:33 | mriedem | sbezverk: we did release some fixes for ocata in 15.0.1 earlier in the week, | |
| 23:40:39 | mriedem | so if you're upgrading, i'd use 15.0.1 | |
| 23:41:13 | sbezverk | mriedem: I brining up at the gate ocata images in kolla-kubernetes project | |
| 23:41:41 | sbezverk | what worked with stable/newton seems broken in ocata, but it might be our issue too.. | |
| 23:42:57 | mriedem | sbezverk: i guess i'd need a more specific example of what's not working | |
| 23:43:56 | Sukhdev | dear Nova folks, after fresh install of devstack, Nova continue to return "No Valid host found" error - can somebody provide some wisdom, please? See the details here - http://paste.openstack.org/show/603034/ | |
| 23:44:29 | sbezverk | mriedem: :) glad you asked. When I start instance I get " Placement API service is not responding." in nova scheduler log | |
| 23:44:59 | mriedem | sbezverk: are you starting the placement service before the nova-scheduler service? | |
| 23:45:04 | sbezverk | mriedem: it looks like connectivity issue but nothing change other than just version of images | |
| 23:45:12 | mriedem | is there a "placement" endpoint in the service catalog? | |
| 23:45:37 | sbezverk | mriedem: yep, service catalog shows placement entries | |
| 23:45:38 | mriedem | is nova.conf for the scheduler configured to use placement in the [placement] section, and are the credentials in there correct? | |
| 23:46:13 | sbezverk | mriedem: all valid points, but as I said nothing changed in the gate job other than image version | |
| 23:46:30 | mriedem | the scheduler didn't use placement in newton, | |
| 23:46:34 | mriedem | so that's a main different with ocata | |
| 23:46:38 | sbezverk | mriedem: was there any change in endpoint registrations between newton and ocata? | |
| 23:46:46 | mriedem | in newton, only the nova-compute service tried connecting to the placement service | |
