| #openstack-nova - 2019-09-06 | |||
| 19:59:36 | efried | aspiers: beaut, thanks for following up. +A | |
| 20:04:15 | aspiers | efried: yw. Don't hesitate to ask if I can (attempt to) help explain other oddities in the remaining two patches | |
| 20:22:07 | mriedem | artom: dansmith: since stephen and sean aren't around, i'll ask you this https://review.opendev.org/#/c/621476/62/nova/api/openstack/compute/server_topology.py@66 | |
| 20:22:10 | mriedem | since i don't know numa | |
| 20:22:53 | dansmith | same pagesize on all cells, is that what you mean? | |
| 20:22:57 | mriedem | yeah | |
| 20:23:21 | dansmith | they will all have a pagesize and they'll all be identical | |
| 20:23:30 | dansmith | I asked that earlier in artom's series | |
| 20:23:42 | mriedem | if they will all have a page size why is that conditional? | |
| 20:24:12 | dansmith | oh, not sure they will all always have a pagesize, but if any do, they'll be the same | |
| 20:24:35 | dansmith | now, that's a libvirt/x86 thing.. I can imagine power allowing multiples because some team in DB2 asked for it in 1996 | |
| 20:24:54 | mriedem | ok, that works for me | |
| 20:24:55 | dansmith | all that probably depends on the hypervisor and arch | |
| 20:25:11 | mriedem | this is an intel (tm) api so don't worry about it | |
| 20:25:15 | dansmith | so I'm sure this api will be broken for other ones that aren't considered here | |
| 20:25:19 | dansmith | WONderful | |
| 20:25:46 | mriedem | powerstackers was burned out of governance b/c eric wouldn't lead them anymore | |
| 20:25:59 | mriedem | and the z folks have moved onto openshift on mainframes | |
| 20:26:06 | dansmith | shocking | |
| 20:26:37 | mriedem | has to be weird when the german customers ask for sles + openshift on their z mainframe | |
| 20:52:51 | mriedem | so this is the 2.78 server numa topology command output right now in the proposed change: http://paste.openstack.org/show/772110/ | |
| 20:52:54 | mriedem | that....sucks | |
| 20:58:12 | sean-k-mooney | libvirt/qemu support having muliple page size even in the same numa node but we dont support that in openstack and likely never will | |
| 20:58:40 | mriedem | sean-k-mooney: ok i'll stop writing up that spec for ussuri | |
| 20:58:43 | mriedem | i thought you'd be on board | |
| 20:58:48 | mriedem | but i guess you don't like that kind of excitement | |
| 20:59:10 | sean-k-mooney | if you want to debug it when it does not work feel free | |
| 20:59:23 | mriedem | heh | |
| 20:59:31 | mriedem | obviously i'm joking | |
| 20:59:55 | mriedem | i've been trying to come up with some kind of hardware schmorgasbord name generator thing to get your goat | |
| 21:00:45 | sean-k-mooney | just pick 3 random letters and its proably some future NFV hardware thing | |
| 21:00:51 | mriedem | FUK | |
| 21:01:01 | sean-k-mooney | :) | |
| 21:01:09 | mriedem | failover uber kernel | |
| 21:01:13 | mriedem | it's a new DR thing | |
| 21:01:28 | sean-k-mooney | i thought it was a brexit reference | |
| 21:01:35 | sean-k-mooney | but ok :) | |
| 21:01:37 | mriedem | you've been boris'ed | |
| 21:01:59 | mriedem | btw https://www.youtube.com/watch?v=dXyO_MC9g3k if you haven't seen that, it's pretty good | |
| 21:02:35 | sean-k-mooney | i have not, i look forword to it :) | |
| 21:04:12 | mriedem | ok, time for some cli design, | |
| 21:04:15 | mriedem | who's in? | |
| 21:04:17 | mriedem | http://paste.openstack.org/show/772111/ | |
| 21:05:02 | mriedem | that's better than before, but the list of nodes in json string is not great, | |
| 21:05:23 | sean-k-mooney | is that the output for the toplogy api? | |
| 21:05:25 | mriedem | but if you dumped each node dict as a separate property, what would you name the property? because that host_node field is only in the response for admins, | |
| 21:05:29 | mriedem | yeah, in the cli | |
| 21:05:31 | mriedem | proposed cli | |
| 21:05:55 | mriedem | so if you're an admin, you could name each one as node{host_node} so like node0 and node1 | |
| 21:06:01 | sean-k-mooney | can we pretty print the json blob | |
| 21:06:11 | mriedem | but if you're not admin, calling them node0 or node1 could make the user think they are actually on those physical host numa nodes | |
| 21:06:57 | mriedem | hmm, maybe | |
| 21:14:58 | sean-k-mooney | its a litte more readable. http://paste.openstack.org/show/772112/ i didnt put it in the ascis table | |
| 21:15:11 | sean-k-mooney | but you could also do somithing like | |
| 21:15:44 | mriedem | that's what i already have http://paste.openstack.org/show/772111/ | |
| 21:16:02 | sean-k-mooney | |node.[0].cpu_pinning | {"0": 0,"1": 5} | |
| 21:16:10 | mriedem | anyway, i've got this better than it was so i'll push it up and someone else can hack on it | |
| 21:16:22 | mriedem | it's not even my patch | |
| 21:17:48 | sean-k-mooney | the latest windows update sucks ... | |
| 21:17:57 | mriedem | 10...? | |
| 21:18:02 | sean-k-mooney | ya | |
| 21:18:07 | mriedem | i'm rocking 7 | |
| 21:18:28 | sean-k-mooney | it install an update last night and now its haning if i boot it in a vm | |
| 21:18:49 | sean-k-mooney | if i reboot the host indo the same windwos install its fine | |
| 21:21:35 | sean-k-mooney | i did like 7. i think i still have my 7 ultimate 64bit dvd around somewhere. | |
| 21:21:57 | mnaser | efried_afk: thanks for driving the SIGHUP patches stuff, i ran out of bandwidth | |
| 21:22:15 | efried | mnaser: yahyoubetcha. Glad to have that fixed finally. | |
| 21:22:37 | prometheanfire | os-brick update is breaking nova :( https://review.opendev.org/680339 | |
| 21:22:59 | efried | prometheanfire: does cinder know? | |
| 21:23:04 | efried | (I didn't click yet) | |
| 21:23:15 | mnaser | AttributeError: 'module' object has no attribute 'NVMeConnector' | |
| 21:23:50 | mnaser | https://github.com/openstack/os-brick/commit/0f057aee6e0351bdef68fadf1fc56ac315027c98 | |
| 21:23:53 | prometheanfire | no, test fails were in nova so pinged you first | |
| 21:24:01 | mnaser | im guessing those are the fails | |
| 21:24:11 | mnaser | the module was renamed | |
| 21:24:24 | openstackgerrit | Matt Riedemann proposed openstack/python-novaclient master: Microversion 2.78 - show server topology https://review.opendev.org/670790 | |
| 21:25:15 | sean-k-mooney | are the nova unit test mocking stuff in os-bricks | |
| 21:25:20 | prometheanfire | try import except import? | |
| 21:25:33 | mnaser | btw | |
| 21:25:36 | mnaser | there is some context here https://review.opendev.org/#/c/643421/ | |
| 21:27:08 | sean-k-mooney | ok so we are importing the conector object in the test | |
| 21:27:41 | mnaser | `initiator.NVME` that was left around for backwards compat | |
| 21:28:01 | mnaser | but the connector did not keep a backwards compat | |
| 21:29:07 | mnaser | i mean as a work around you could fall back to asserting the initiator used instead of the connector used | |
| 21:29:45 | sean-k-mooney | so the real driver code use the factory method to consurct it | |
| 21:29:47 | sean-k-mooney | https://github.com/openstack/nova/blob/master/nova/virt/libvirt/volume/nvme.py#L34 | |
| 21:30:04 | mnaser | sean-k-mooney: it uses `initiator.NVME` which is still around | |
| 21:30:23 | sean-k-mooney | i think the real fix is to not assert thing abot the data type of an external lib | |
| 21:30:39 | mnaser | https://github.com/openstack/os-brick/blob/0f057aee6e0351bdef68fadf1fc56ac315027c98/os_brick/initiator/connector.py#L117-L122 | |
| 21:30:40 | mnaser | cause thats still around | |
| 21:30:52 | sean-k-mooney | mnaser: yes but i guess they considerd as part of the public interface | |
| 21:31:01 | sean-k-mooney | and the conector object are not | |
| 21:31:30 | mnaser | maybe the test should mock `connector.InitiatorConnector.factory` and make sure it calls it with initiator.NVME ? | |
| 21:31:39 | mnaser | which is enough to know we are doing the right thing(tm) | |
| 21:32:00 | sean-k-mooney | maybe but its stil mocking stuff we dont own | |
| 21:32:06 | sean-k-mooney | but that seams safer | |
| 21:32:16 | mnaser | well at least it makes sure that we're creating a connector with the right type of initiator | |
| 21:32:16 | sean-k-mooney | sice we are mocking somethign we are calling | |
| 21:32:29 | mnaser | which i think is the biggest thing that test is supported to do.. | |
| 21:32:43 | sean-k-mooney | right but that is not novas job to test | |
