| mnaser | manila + force_config_drive in nova = broken :( | 18:13 |
| mnaser | config drive is presented at /dev/vdb on first boot, /dev/vdc is the actual mounted share. | 18:13 |
| mnaser | on reboot, /dev/vdb becomes the share, /dev/vdc becomes configdrive | 18:13 |
| bswartz | mnaser: that sounds like a bug specific to the generic driver | 18:14 |
| mnaser | it is indeed bswartz | 18:14 |
| bswartz | definitely something we should fix | 18:14 |
| mnaser | i am slightly annoyed by nova too | 18:15 |
| mnaser | if force_config_drive is true, its not possible to change it via the image metadata | 18:15 |
| mnaser | https://github.com/openstack/nova/blob/stable/mitaka/nova/virt/configdrive.py#L168-L177 | 18:15 |
| mnaser | so i cant even work around it | 18:15 |
| bswartz | to change what with the image metadata? the option? | 18:17 |
| bswartz | I think the "force" in the option name indicates the option overrides anything you set elsewhere | 18:17 |
| mnaser | bswartz yeah but I figured I could disable it in the image metadata to override | 18:18 |
| mnaser | but yeah, assumingly force_config_drive means enforce it | 18:18 |
| mnaser | tried to work around it by mkfs.ext4 /dev/vdb after a reboot | 18:19 |
| mnaser | but now the machine gets stuck on boot | 18:19 |
| bswartz | the generic VM does? | 18:25 |
| bswartz | so does the fix need to go into the generic driver or the service image? | 18:25 |
| mnaser | bswartz i believe thats its cinder to blame in this case | 18:26 |
| mnaser | it reports back /dev/vdb even if its on /dev/vdc .. on reboot it becomes /dev/vdb though | 18:26 |
| mnaser | so for all that manila cares, it's getting the wrong info | 18:27 |
| bswartz | cinder reports that? | 18:28 |
| bswartz | cinder doesn't really have any idea what the device name is | 18:28 |
| mnaser | sorry nova | 18:28 |
| mnaser | nova volume-attachments <uuid> = device: /dev/vdb | 18:29 |
| bswartz | yeah that does sound like nova is lying | 18:30 |
| mnaser | so nova should report it as /dev/vdc and on reboot /dev/vdb | 18:30 |
| bswartz | does config drive not provide a way to control which device it uses? | 18:30 |
| mnaser | yes and no... i think it attempts to mount it as the "last device" | 18:32 |
| mnaser | im trying to remember where i've seen this cod | 18:32 |
| bswartz | well one fix would be to change manila to not rely on the device names/numbers from nova/cinder and instead to rely on UUIDs | 18:35 |
| mnaser | i think the unfortunate thing is that there is no way to reliably determine that either :( | 18:36 |
| bswartz | well that's something we can fix in manila | 18:38 |
| mnaser | http://docs.openstack.org/developer/nova/block_device_mapping.html#intermezzo-problem-with-device-names | 18:38 |
| mnaser | the block device mapping should pin configdrive correctly imho | 18:39 |
| mnaser | if configdrive is at /dev/vdb, it should stay there, foreve.r | 18:39 |
| mnaser | bah this is frustrating, basically means that we cant use manila till we figure out what we do with this | 18:42 |
| mnaser | bswartz of interest for manila - https://github.com/kubernetes/kubernetes/issues/33128 | 18:47 |
| bswartz | mnaser: that bug seems to similarly confuse nova and cinder | 18:48 |
| bswartz | because again cinder knows nothing of the attachment device | 18:49 |
| mnaser | similar issue, kubernetes attempts to attach cinder volumes and reworked how they detect volumes, ignoring nova reported info | 18:49 |
| mnaser | i guess our workaround will be to set img_config_drive=mandatory for all images and switch force_config_drive off | 18:54 |
| bswartz | ........... | 19:04 |
| bswartz | sorry that's the baby hammering on the keyboard | 19:04 |
| bswartz | if that workaround works, make sure to mention it in the bug you file | 19:05 |
| bswartz | so others will have a solution until we can fix the underlying problem | 19:05 |
| mnaser | will do so, also of interest to this convo is something i was pointed at from openstack-nova http://lists.openstack.org/pipermail/openstack-dev/2016-September/104617.html | 19:06 |
