| 20:20:40 | bauzas | jaypipes: leaving notes meanwhile | |
| 20:21:23 | openstackgerrit | OpenStack Proposal Bot proposed openstack/nova: Updated from global requirements https://review.openstack.org/420844 | |
| 20:30:33 | jaypipes | bauzas: k, done. | |
| 20:30:50 | bauzas | jaypipes: see my comment for context in gerrit | |
| 20:33:17 | mriedem | whew | |
| 20:33:44 | mriedem | dansmith: yeah probably, which is actually what i started working on | |
| 20:33:50 | mriedem | before the call i just got off of happened | |
| 20:34:40 | bauzas | jaypipes: thoughts on that ? | |
| 20:35:13 | dansmith | mriedem: okay | |
| 20:35:29 | bauzas | jaypipes: I honestly totally agree with you that using a reportclient is somehow sad | |
| 20:35:44 | bauzas | jaypipes: but I wanted to be pragmatic | |
| 20:38:41 | openstackgerrit | Andrey Kurilin proposed openstack/python-novaclient: DO NOT MERGE: check OSC https://review.openstack.org/420941 | |
| 20:43:41 | mriedem | ok on the api node i create nova_subnode_cell db, and then create subnode-cell cell with the db connection to the nova_subnode_cell db and transport_url to the primary node's same mq | |
| 20:43:48 | mriedem | transport-url is going to be the same for all of these | |
| 20:44:00 | mriedem | then on the subnode setup after n-cpu is running i need to run discover_hosts | |
| 20:45:31 | mriedem | now i need to remember how to awk stuff, damn | |
| 21:01:26 | jaypipes | bauzas: sorry, reading now. got pulled away | |
| 21:01:32 | bauzas | np | |
| 21:07:36 | comstud | mriedem: well, there's your problem | |
| 21:08:28 | jaypipes | comstud: blast from the past! howdy. | |
| 21:08:36 | comstud | yo :) | |
| 21:08:41 | jaypipes | bauzas: ok, fair point on the reporting client thing. I can go along with that. | |
| 21:08:56 | jaypipes | bauzas: with a promise to clean up ex post facto. | |
| 21:09:05 | bauzas | jaypipes: my change is still there | |
| 21:09:15 | jaypipes | bauzas: I still would need to see a ComputeNodeList.get_all_by_uuids() though. | |
| 21:09:18 | bauzas | jaypipes: I mean the placementclient one | |
| 21:09:29 | jaypipes | bauzas: understood. | |
| 21:09:29 | bauzas | jaypipes: sure, I'll redo it | |
| 21:09:49 | openstackgerrit | Claudiu Belu proposed openstack/nova: hyper-v: Adds support for VMs with nested virtualization https://review.openstack.org/398509 | |
| 21:09:50 | openstackgerrit | Claudiu Belu proposed openstack/nova: Adds CPUFeaturesField to ImageMetaProps https://review.openstack.org/420960 | |
| 21:10:10 | bauzas | jaypipes: the question I was wondering about the placementclient is that it would be reasonable to only provide CRUD ops in it | |
| 21:10:33 | bauzas | jaypipes: or if I'd rather work on objectifying that client | |
| 21:10:52 | bauzas | cutting by just the CRUD ops could possible be merged sooner | |
| 21:11:05 | jaypipes | bauzas: no, I think just pulling get/put/post/safe_connect into a class is correct. | |
| 21:11:05 | mriedem | comstud: it's ok, mrodden stopped by just at the right time and gave me the awk i needed | |
| 21:11:18 | bauzas | but I'd tend to prefer having a placementclient that would have resources in it | |
| 21:11:36 | bauzas | jaypipes: okay, then I'll continue to keep my change up-to-date then | |
| 21:11:58 | bauzas | it'll just be a top change, not a dependent one | |
| 21:12:04 | jaypipes | bauzas: I'd prefer composition over inheritance as I mentioned before, and keep state in separate objects (i.e. not the PlacementClient class itself but the object that contains a PlacementClient object) | |
| 21:12:39 | bauzas | jaypipes: composition is already in the last PS | |
| 21:12:42 | bauzas | AFAIR | |
| 21:12:49 | bauzas | unless I forgot to upload it | |
| 21:14:46 | bauzas | jaypipes: state of what? it's mostly stateless if you except the disabled thing | |
| 21:15:08 | jaypipes | bauzas: I mean the _resource_providers dict. | |
| 21:15:22 | bauzas | jaypipes: in that case, it's fine, I left that | |
| 21:15:29 | jaypipes | bauzas: I would prefer that not be in the PlacementClient. That should be in the ReportingClient, yes? | |
| 21:15:40 | bauzas | correct | |
| 21:15:43 | jaypipes | cool | |
| 21:15:51 | bauzas | jaypipes: https://review.openstack.org/#/c/417111/7/nova/scheduler/client/report.py is pretty seamless | |
| 21:16:26 | jaypipes | bauzas: oui. absolument. | |
| 21:16:49 | jaypipes | bauzas: though I'd change SafeConnectDecorator to @client.safe_connect :) | |
| 21:18:12 | bauzas | jaypipes: but I need to keep a state, hence the deco object :) | |
| 21:19:47 | jaypipes | bauzas: you could just look for a consistently-named attribute, no? | |
| 21:20:38 | bauzas | jaypipes: I could use a global var | |
| 21:21:35 | jaypipes | bauzas: or a consistently-named attr :) | |
| 21:22:22 | jaypipes | bauzas: else you could require classes to implement a get_placement_client() method. | |
| 21:22:27 | jaypipes | bauzas: or something like that. | |
| 21:22:29 | mriedem | dansmith: hmm, should create_cell sync the db schema for that cell? | |
| 21:23:00 | bauzas | jaypipes: I thought of the latter | |
| 21:23:16 | bauzas | jaypipes: anyway, I'll see | |
| 21:24:28 | openstackgerrit | Dan Smith proposed openstack/nova: WIP Move instance creation to conductor https://review.openstack.org/319379 | |
| 21:24:46 | dansmith | mriedem: hmm, I dunno.. | |
| 21:24:54 | dansmith | maybe optional? --sync-that-mofo-too? | |
| 21:25:44 | mriedem | yeah because the problem is running nova-manage db sync on my subnode cell | |
| 21:27:59 | mriedem | dansmith: fuck i've been doffm'ed https://github.com/openstack/nova/blob/7cb416546a2c6d8eb36cbf9acfde776d54a26811/nova/cmd/manage.py#L630 | |
| 21:28:20 | dansmith | mriedem: um, congrats? | |
| 21:28:32 | mriedem | just looks like we thought about this before | |
| 21:28:51 | mriedem | so to sync this db i have to hack the nova.conf | |
| 21:29:06 | mriedem | otherwise it's going to be pointing at the nova db connection on the primary node | |
| 21:29:40 | dansmith | mriedem: you could make that work for other cells easily, right? | |
| 21:29:53 | dansmith | just list all the mappings and target them before sync like cell0 does | |
| 21:29:53 | mriedem | yeah we just get all the cell mappings and sync them | |
| 21:31:17 | mriedem | the note here seems wrong https://github.com/openstack-dev/devstack/blob/master/lib/nova#L687 | |
| 21:31:46 | mriedem | nova-manage db sync is just going to sync the local main db, or whatever is in CONF.database.connection | |
| 21:32:31 | dansmith | yeah | |
| 21:32:36 | mriedem | today we're getting cell0 synced b/c of https://github.com/openstack-dev/devstack/blob/master/lib/nova#L950 | |
| 21:32:43 | dansmith | mriedem: could also make db sync take a cell uuid or osmeting | |
| 21:33:15 | mriedem | so in the cells v1 case i don't see where we even sync the cell0 db | |
| 21:33:39 | dansmith | the cellsv1 case? | |
| 21:33:51 | mriedem | this https://github.com/openstack-dev/devstack/blob/master/lib/nova#L951-L956 | |
| 21:34:05 | dansmith | map_cell0 does it | |
| 21:34:25 | mriedem | umm, | |
| 21:34:39 | mriedem | nope | |
| 21:34:40 | mriedem | https://github.com/openstack/nova/blob/7cb416546a2c6d8eb36cbf9acfde776d54a26811/nova/cmd/manage.py#L1157 | |
| 21:34:44 | mriedem | it creates the cell0 mapping | |
| 21:34:46 | mriedem | but doesn't sync it | |
| 21:34:54 | dansmith | oh hmm, yeah | |
| 21:34:56 | dansmith | I thought it did | |
| 21:35:30 | mriedem | simple_cell_setup is the only one that does https://github.com/openstack/nova/blob/7cb416546a2c6d8eb36cbf9acfde776d54a26811/nova/cmd/manage.py#L1105 | |
| 21:35:33 | dansmith | wait, no.. the db sync does it for cellsv1 right? | |
| 21:36:01 | mriedem | as far as i can tell, db sync is going to just sync the 'main' db | |
| 21:36:18 | dansmith | no, it does cell0 and the main one | |
| 21:36:31 | dansmith | https://github.com/openstack/nova/blob/7cb416546a2c6d8eb36cbf9acfde776d54a26811/nova/cmd/manage.py#L635 | |
| 21:36:36 | mriedem | oh yeah | |
| 21:36:39 | dansmith | it queries for cell0 and does it, it just doesn't list | |
| 21:37:08 | mriedem | so, | |
| 21:37:13 | mriedem | i think i'm just going to address https://github.com/openstack/nova/blob/7cb416546a2c6d8eb36cbf9acfde776d54a26811/nova/cmd/manage.py#L630 | |
| 21:37:16 | mriedem | and do the cell mapping list | |
| 21:37:19 | mriedem | and sync those mofos | |
| 21:38:02 | mriedem | i mean we could also do this in create_cell easily | |
