| 22:14:01 | jaypipes | efried: I thought all API changes required a spec? | |
| 22:14:20 | efried | jaypipes: Apparently that's true; see above. | |

| 23:03:55 | mriedem | mdbooth: you should take a look at this https://review.openstack.org/#/c/542646/ | |
| 23:19:05 | tetsuro | is avolkov around? | |
| 23:20:12 | tetsuro | I’d like you to answer the question in https://review.openstack.org/#/c/539865/. … or anyone who can help me. | |
| 23:47:44 | mnaser | is there any way i can do something to get output from nova-compute about memory usage | |
| 23:47:53 | mnaser | i have a nova-compute process sitting on 13gb of ram. | |
| 23:48:21 | mnaser | (before i restart it, just to get helpful information out) | |
| 23:49:30 | melwitt | mriedem: these comments aren't related to the patch, are they? just a suggestion on some better cleanup we could do in a separate patch? https://review.openstack.org/#/c/520158/3/nova/compute/api.py@2826 | |
| 23:50:14 | mnaser | wow... actually almost every nova-compute process is using 13g of memory.. | |

| 00:00:21 | efried | edleafe, mriedem, melwitt, jaypipes, cdent: ^ | |
| 00:04:28 | melwitt | mnaser: the only thing I know of is the hypervisor-stats type of things e.g. https://docs.openstack.org/nova/pike/admin/common/nova-show-usage-statistics-for-hosts-instances.html | |
| 00:04:45 | melwitt | mnaser: but you may be able to use something like this to dig deeper https://github.com/rogerhu/gdb-heap | |
| 00:05:10 | mnaser | melwitt: looks like a bunch of reading but i'll look into it because it seems a bit (very) high | |
| 00:05:19 | mnaser | melwitt: thank you for that information | |
| 00:08:37 | melwitt | the only other thing could be a GMR (guru meditation report) | |
| 00:09:32 | melwitt | I'm not sure that would help too much https://docs.openstack.org/nova/latest/reference/gmr.html | |
| 00:10:21 | mmedvede | mriedem: ok, I'll change that | |
| 00:10:49 | melwitt | but it should be simple to try, send USR2 to the nova-compute pid | |
| 00:39:02 | openstackgerrit | Merged openstack/nova master: Fix PatternPropertiesTestCase for py 3.6 https://review.openstack.org/545798 | |

| 01:04:31 | tetsuro | could anyone review https://review.openstack.org/#/c/531347/? It got one +2 a month ago. | |
| 01:35:51 | mriedem | melwitt: yeah i guess, i probably hadn't noticed that when rebasing it last time | |
| 01:36:04 | mriedem | mnaser: my guess would be any caching done in the nova.compute.manager.resource_tracker | |
| 01:36:15 | mriedem | mnaser: we cache some placement-related stuff in there now | |
| 01:36:32 | mriedem | but it shouldn't be much.. | |
| 01:37:13 | mriedem | https://github.com/openstack/nova/blob/master/nova/compute/resource_tracker.py#L133 | |
| 01:37:25 | melwitt | mriedem: okay, just wanted to confirm whether there's more to do on that patch before I +W | |
| 01:37:57 | mriedem | melwitt: as far as i know, not tracking the created snapshots and cleaning them up is latent behavior | |
| 01:38:13 | melwitt | mriedem: that's what it looked like to me too | |
| 01:38:52 | mriedem | mnaser: and the RT has an in-memory report client that has a cache of its own https://github.com/openstack/nova/blob/stable/pike/nova/scheduler/client/report.py#L233 | |

| 07:12:28 | akki__ | Hello, I have a running OpenStack setup on which I was able to launch VMs. But I want to move to use LXC instantiation. So, for that, I have installed nova-compute-lxd on my current setup of OpenStack with basic services installed in it. I have installed nova-compute-lxd on my compute node (Ubuntu 16.04), changed the virt-type to 'lxc' in my nova.conf and then restarted the nova-compute service. | |
| 07:12:52 | akki__ | After this, I launched an instance and it failed after some time and gives the following error: [Error: No valid host was found. There are not enough hosts available.]. Could you please guide what else is required to launch container on OpenStack setup? What configurations will I need to configure LXD and my nova user to see the LXD daemon. I am new to this, every help appreciated. | |

| 09:59:16 | kashyap | Hi, can someone point to PTG Nova agenda etherpad? | |
| 09:59:31 | cdent | kashyap: https://etherpad.openstack.org/p/nova-ptg-rocky | |
| 09:59:39 | kashyap | cdent: Thank you | |
| 10:01:27 | bauzas | meh, LP timeout :( | |
| 10:01:33 | bauzas | hello folks, btw. | |

| 10:34:50 | openstack | Launchpad bug 1740025 in OpenStack Compute (nova) "LVM Sparse Volumes broken" [Undecided,New] | |
| 10:34:51 | bauzas | agreed ? | |
| 10:35:34 | mdbooth | bauzas: Reading | |
| 10:36:22 | mdbooth | bauzas: Why wontfix? | |
| 10:36:55 | mdbooth | I recall there being severe problems with sparse lvm | |
| 10:37:03 | mdbooth | Not the specifics, though | |
| 10:38:53 | bauzas | mdbooth: because it looks like a feature | |
| 10:39:21 | bauzas | mdbooth: tbc, you can do thin provisioning with Cinder | |
| 10:39:23 | kashyap | I don't know, would you want the reporter to do the whole spec dance? | |
| 10:39:36 | bauzas | but here, the reporter only uses raw LVM | |
| 10:39:37 | kashyap | It's okay to flesh out the details on the bug, without hurrying to close it | |
| 10:39:47 | mdbooth | bauzas: It reads like a bug to me. | |
| 10:39:51 | kashyap | Yeah, to me too. | |
| 10:40:05 | bauzas | so, in case you create LVM volumes having X size | |
| 10:40:08 | bauzas | then, meh | |
| 10:40:15 | mdbooth | Sparse LVM is a thing, and if we were using it correctly, I would expect the scenario described to work. | |
| 10:40:39 | bauzas | mdbooth: why can't the reporter create LVs that are more than 64MB ? | |
| 10:41:01 | bauzas | that's something I don't understand | |
| 10:41:02 | mdbooth | bauzas: I'm guessing because we didn't create the sparse lv correctly. | |
| 10:41:20 | mdbooth | bauzas: As I said, though, I'm pretty sure I recall severe problems in our implementation of sparse lvm. | |
| 10:41:20 | lyarwood | yeah that's not up to the user, n-cpu is creating the lv's | |
| 10:41:29 | bauzas | ah ok | |
| 10:41:34 | mdbooth | severe == How could it ever possibly have worked | |
| 10:41:41 | bauzas | so when nova creates the lv, it asks for a size | |
| 10:41:48 | bauzas | that's not the image | |
| 10:41:48 | bauzas | meh | |
| 10:42:04 | mdbooth | bauzas: It's like creating a sparse file, except lvm | |
| 10:42:12 | bauzas | and then tries to thin provision by itself, while cinder can do that far better | |
| 10:42:31 | mdbooth | It creates a sparse block device, which only allocated blocks from the lvm block pool when they're used | |
| 10:42:35 | mdbooth | Or it's supposed to, anyway | |
| 10:42:36 | bauzas | looks to me we barely support it | |
| 10:42:44 | mdbooth | bauzas: Right. | |
| 10:42:54 | bauzas | yeah I understand the purpose of sparse LVs | |
| 10:42:59 | mdbooth | bauzas: I'm not convinced this has ever worked. However, I'm pretty sure that it was intended to work. | |
