| 10:32:40 | bauzas | mdbooth: but whatever it is, it's still capping at the maximum size given by the flavor ? | |
| 10:32:51 | tojuvone | johnthetubaguy, Yes and there is different sides. Generic "host state" to be outside with notif about change makes it again easier to catch that in monitoring hosts | |
| 10:32:57 | mdbooth | bauzas: Yes, flavor is a maximum. | |
| 10:33:37 | mdbooth | The issue reported here is that if your instances are predominantly BFV, then RM thinks you ran out of disk long before you actually did. | |
| 10:34:02 | mdbooth | In fact, RM thinks you have negative disk space | |
| 10:34:06 | bauzas | mdbooth: but those instances could max out up to that size | |
| 10:34:21 | johnthetubaguy | tojuvone: yeah, lets get that admin view and user view pinned down nicely | |
| 10:34:40 | mdbooth | bauzas: Interesting idea. Not without rescheduling, I think. | |
| 10:34:56 | mdbooth | bauzas: I think you'd have to resize. | |
| 10:35:08 | bauzas | mdbooth: if my BDM source type is image | |
| 10:35:19 | mdbooth | Even then, can you change the non-volume bdms? | |
| 10:36:00 | lyarwood | don't we have periodic jobs already checking the sizes of local disks etc on each of the hosts? I assumed we were already reporting this somewhere for quotas etc? | |
| 10:36:13 | bauzas | the size on the disk can grow for a non-volume, right? | |
| 10:36:26 | mdbooth | bauzas: I can't think of anything in the libvirt driver which allows resizing/adding ephemeral disks, except for the resize operation | |
| 10:36:30 | mdbooth | bauzas: No | |
| 10:36:41 | mdbooth | This isn't overcommit. | |
| 10:36:55 | bauzas | I'm puzzled honestly | |
| 10:36:56 | mdbooth | This is, the user specified a BDM with a smaller disk size. | |
| 10:37:07 | mdbooth | Or in the case of BFV, no disk at all. | |
| 10:37:34 | bauzas | okay, let's admit a flavor of 0 | |
| 10:40:53 | bauzas | mdbooth: tbh, I'm not particularly seasoned with BDMs, so reading https://docs.openstack.org/developer/nova/block_device_mapping.html | |
| 10:41:11 | mdbooth | bauzas: You're not alone :) | |
| 10:41:41 | bauzas | mdbooth: I mean, I trust you when you describe it could be suboptimal | |
| 10:42:03 | bauzas | mdbooth: I'm just tryint to get more picture to know whether it's by design | |
| 10:42:40 | bauzas | mdbooth: lemme explain | |
| 10:42:50 | mdbooth | bauzas: So I'm not that familiar with the resource manager code, which was probably pretty apparent yesterday | |
| 10:43:15 | bauzas | mdbooth: that's how community works :) | |
| 10:43:17 | mdbooth | I have a vague understanding of what happens, but I'm not entirely sure which bits do what, or even what all the bits are. So I did some digging. | |
| 10:44:07 | mdbooth | I *think* that code above is what RM ultimately uses to update the scheduler's understanding of host resource usage, based on scheduling a specific instance. | |
| 10:44:34 | mdbooth | Which I *think* means that, if it's wrong, something up the line will ultimately add up a bunch of wrong numbers. | |
| 10:54:03 | openstackgerrit | jichenjc proposed openstack/nova master: add zvm migration object https://review.openstack.org/414090 | |
| 10:58:00 | BobBall | mriedem: Many thanks for your help + shepherding on the XAPI live migration fix :) I'm really glad it made Ocata. Now it's up to us to make sure it doesn't happen again. | |

| 11:36:55 | openstackgerrit | Silvan Kaiser proposed openstack/nova master: Removes getfattr from Quobyte Nova driver https://review.openstack.org/428646 | |
| 11:41:35 | mdbooth | bauzas: Hey, what does scheduler/client/report.py do? That's also not quite right. | |
| 11:41:58 | bauzas | mdbooth: it's both updating the DB and also calling the placement API | |
| 11:42:13 | openstackgerrit | Artom Lifshitz proposed openstack/nova-specs master: Virtual guest device role tagging https://review.openstack.org/435397 | |
| 11:42:38 | mdbooth | bauzas: Is the behaviour of DiskFilter provided by anything else, btw? | |
| 11:42:47 | mdbooth | Can we just deprecate it in favour of X? | |
| 11:59:00 | openstackgerrit | Sean Dague proposed openstack/nova master: Verify project_id when quotas are checked https://review.openstack.org/435010 | |
| 12:01:43 | lyarwood | sdague: morning, just looking at https://review.openstack.org/#/c/433825/ - would https://review.openstack.org/435406 - disabling gate-tempest-dsvm-full-devstack-plugin-ceph-ubuntu-trusty for stable/mitaka help here? | |
| 12:02:14 | lyarwood | or should we skip this with another devstack rc file? | |
| 12:02:34 | lyarwood | s/skip this/skip the test/g | |
| 12:03:04 | sdague | lyarwood: yeh, we could make it non voting on mitaka to get that other fix in | |
| 12:03:42 | sdague | lyarwood: is anyone working on the ceph issue? | |
| 12:04:21 | lyarwood | sdague: I was about to add the fact that it's non-voting to the ptg etherpad, I don't think anyone is working on it tbh | |
| 12:06:37 | bauzas | mdbooth: so, the DiskFilter is now legacy | |
| 12:06:53 | bauzas | mdbooth: given we now use the Placement API for verifying the disk usage | |
| 12:07:08 | bauzas | we still use it for the CachingScheduler | |
| 12:07:28 | mdbooth | bauzas: So it's worth fixing ResourceTracker? | |
| 12:08:32 | bauzas | mdbooth: well, the RT is still used for providing the resources | |
| 12:08:48 | mdbooth | bauzas: Ok, cool. | |
| 12:08:49 | bauzas | mdbooth: when are you arriving in ATL ? we could be discussing about that during the PTG | |
| 12:09:12 | mdbooth | bauzas: You forget :) | |
| 12:10:04 | mdbooth | ATL or the alps... which to choose? | |
| 12:10:05 | cdent | wait, does this mean that I won't get a chance to have the beers with mdbooth that I was supposed to have in BCN in ATL? | |
| 12:10:18 | mdbooth | cdent: Bah! | |
| 12:10:23 | bauzas | mdbooth: ooooooh right :p | |
| 12:10:42 | cdent | I was coping just fine until now, but this is the last straw. | |
| 12:10:46 | bauzas | mdbooth: lemme just take a picture for you :p | |
| 12:10:51 | mdbooth | cdent: lol | |
| 12:10:59 | mdbooth | bauzas: Yeah, yeah, I know | |
| 12:11:27 | mdbooth | cdent: If we took an American view, we both live in London and could therefore meet up any time | |
| 12:11:50 | lyarwood | mdbooth: it's just down the road from you right? | |
| 12:11:51 | cdent | heh, yeah. weird that. | |
| 12:12:09 | bauzas | heh | |
| 12:12:23 | bauzas | mdbooth: snow will be awesome | |
| 12:12:28 | mdbooth | cdent: Wait, do you actually live in London? | |
| 12:12:33 | cdent | cornwall | |
| 12:12:40 | mdbooth | Right... :) | |
| 12:12:47 | mdbooth | South West London | |
| 12:12:54 | cdent | ha! | |
| 12:13:16 | lyarwood | the commuter belt | |
| 12:13:16 | cdent | When bauzas goes outside he sees the snowy mountains. I see the shining blue sea. | |
| 12:13:34 | mdbooth | lyarwood: lol | |
| 12:13:48 | cdent | it certainly feels that way | |
| 12:14:35 | bauzas | heh | |
| 12:14:55 | mdbooth | bauzas: Weather in the mountains next week looks nice | |
| 12:21:22 | bauzas | correct | |
| 12:24:07 | bauzas | mdbooth: just teasing a bit, here is what I had last Sat https://scontent-cdg2-1.xx.fbcdn.net/v/t35.0-12/16709262_10210130727278505_1924147998_o.jpg?oh=da67edbd122e61da21a7d59e8cd13ae7&oe=58A9279F | |
| 12:24:15 | bauzas | :) | |
| 12:24:43 | mdbooth | bauzas: git | |
| 12:24:46 | bauzas | 80cm of pow or around | |
| 12:24:53 | bauzas | and just fresh | |
| 12:25:10 | mdbooth | VT hasn't had fresh for about a week, I think | |
| 12:25:31 | bauzas | planned for tonight IIRC | |
| 12:26:07 | bauzas | either way, I recommend you to enjoy on mornings, afternoons could be a bit not that good | |
