#openstack-nova - 2018-11-02
20:24:30 melwitt nicolasbock: ok, thanks. and when do you get that error? when starting the proxy or when trying to get a new console or?
20:24:51 melwitt do you have a traceback you could paste?
20:24:56 nicolasbock it seems to show up after I create a server
20:25:00 nicolasbock Yes
20:25:08 cdent fried_rice: sanity check me on some mental meanderings please
20:26:05 cdent "generation" can act as a cache invalidator for a resource provider. you can compare generations in various ways, and if it is different from what you think it should be be, then you know to do differently
20:26:17 nicolasbock melwitt (IRC): http://paste.openstack.org/show/734053/
20:26:41 cdent what if: when the generation on an rp changes, it caused a generation bump on its parent
20:27:09 cdent thus: whenever a compute node needing to validate it's tree, it just needed to compare stored generation with the generation of just the root
20:27:27 cdent s/needing/needed/ s/it's/its/
20:27:59 cdent I'm thinking perhaps that's how nested generations should always have worked
20:31:58 mriedem fried_rice: thanks for the ML post, i dumped my brain
20:32:57 melwitt nicolasbock: hm, I haven't seen that before. where have you deployed the console proxy? is it on a host that has a nova.conf with [database]connection set to the cell1 database?
20:33:57 melwitt the traceback looks unrelated to database access issues, but asking just in case
20:35:26 nicolasbock melwitt (IRC): The console proxy is deployed in an LXC container that runs the Nova API
20:35:42 nicolasbock I haven't noticed database acces issues from that container to the Galera container
20:38:41 melwitt nicolasbock: ok. it sounds like it's possible the [spice] config options have been misconfigured, like the address configs. seeing if I can find docs. have you been able to set this up properly before in the past and now it is broken?
20:39:17 nicolasbock No, this is the first time I am setting this up.
20:39:25 nicolasbock I could try an older branch
20:40:30 melwitt no, that's ok, just checking whether this is a regression in behavior you have seen before
20:42:55 nicolasbock I have set `novncproxy_base_url = https://44.81.0.110:6080/vnc_lite.html` in the nova-api container
20:43:04 nicolasbock However, that IP is the IP of the OSA host
20:43:13 nicolasbock Is that possible the issue?
20:43:48 melwitt yeah, I was about to suggest something like that based on what I'm reading in https://docs.openstack.org/nova/latest/admin/remote-console-access.html#spice-console
20:44:31 fried_rice cdent: So far the philosophy has been that the client isn't supposed to "compare" generations at all.
20:45:08 fried_rice They're supposed to be opaque, introspected only by placement itself.
20:45:29 cdent fried_rice: they are supposed to be meaningless, but comparing mine to yours doesn't imply meaning
20:45:36 nicolasbock melwitt (IRC): The "controller" node is the one that runs the API?
20:46:08 melwitt nicolasbock: I notice you are using novnc config options but are running the spice proxy?
20:46:23 fried_rice cdent: It's a subtle distinction - testing for (in)equality versus gt/lt - but it's still treating it as non-opaque on the client.
20:46:26 cdent fried_rice: if we had done etags instead of generations, the way to accomplish the thing I'm describing is with a conditional GET.
20:46:53 fried_rice cdent: but putting that aside for the moment, what you're talking about is overloading the generation to do more than we're doing now.
20:46:57 melwitt nicolasbock: I think there it means the "controller" is where you are running the proxy. and the config options in the [spice] section are on the compute host (compute host is referring to where the proxy is running)
20:46:59 nicolasbock melwitt (IRC): the initial installation was configured to use the spice proxy, but as I was getting these error messages I reconfigured it
20:47:06 cdent fried_rice: I seem to recall seeing generation comparison in report client code, but I may be out of date
20:47:17 cdent no it is doing exactly how a generation is defined
20:47:20 nicolasbock melwitt (IRC): Thanks that clarifies this
20:48:20 nicolasbock melwitt (IRC): I should stop the spicehtml5proxy service
20:50:33 melwitt nicolasbock: I'm not sure. it doesn't look like the spice options are related to the proxy service
20:50:52 melwitt meaning, I think they are consumed by nova-compute, not the proxy
20:52:21 melwitt so I'd fix the options on the host running nova-compute first and then see what happens
20:54:21 nicolasbock Ok, thanks melwitt (IRC) I'll try that
21:37:18 mgagne mriedem: does it *need* to be cell0 database or could it be a different dedicated database?
21:40:15 mriedem mgagne: doesn't need to be cell0,
21:40:20 mriedem that's just what we use in devstack
21:40:25 mriedem b/c we have the api db, cell0 and cell1
21:40:32 mgagne mriedem: does it mean there are 2 schemas/migration in the same database?
21:40:36 mriedem and we want to make sure cell1 is just for instances and compute hosts and such
21:40:40 mriedem no
21:40:51 mriedem cell0 and cell1 have the same schema
21:41:07 mriedem everything used for a [database]/connection config uses the 'nova' schema
21:41:20 mriedem [api_database]/connection uses the 'nova_api' schema
21:41:33 mriedem iow, former is 'nova-manage db sync', latter is 'nova-manage api_db sync'
21:42:04 mgagne ok so it just happens to have the same schema but might not be used for the same purpose from a pure semantic perspective
21:42:57 mgagne because if I put nova_cell0 in database/connection and run map_cell0, I might just end up with nova_cell0_cell0

06:23:14 pvc hi anyone successfully integrate cyborg to nova?
08:56:28 bauzas good morning stackers
09:06:11 pvc bauzas
09:06:15 pvc it is possible to implement cybrog to nova
09:10:14 bauzas it's a long story but some people try to do this
09:13:58 jangutter it's also unlikely to happen in the short term.
09:28:23 johnthetubaguy bauzas: just checking, partly for pvc, but I didn't think we had any code in place to integrate cyborg in master (yet)? Apart from maybe PCI pass-through?
09:31:21 bauzas johnthetubaguy: AFAIK, cyborg directly modifies nova.conf for using PCI passthru, yes
09:31:37 johnthetubaguy ah, got it, thanks
09:31:38 bauzas johnthetubaguy: there was a YVC session
09:32:15 johnthetubaguy yeah, I was more checking there wasn't post PTG progress I didn't know about while I was out of it
