ZFS Pool files are missing!!!

[lionking]

Hey guys!

Need your help please!

I am using Proxmox 2.2 with zpool called: DATA
after a recent reboot my VM's that are stored on DATA won't boot with error the files are missing, when i tried to locate them the whole pool is empty.
but when i run this:

root@proxmox:~# zfs list
NAME USED AVAIL REFER MOUNTPOINT
data 860G 52.5G 860G /data

it shows the right amounts, still no files!
after some research i understand it is some kinda mount issue, which i have no idea how to fix.

Please help!
Sincerely
Andrey

Do you see them mounted eg. via the `mount` command? If not, try `zfs mount -a`.

Thank you very much for your reply! when i run it: root@proxmox:~# zfs mount -a
cannot mount '/data': directory is not empty

Well, in that case probably Proxmox created dirs for some PVE storage you configured in the zfs root. You're safe to delete everything there before mounting the zfs datasets (but do check it before doing so). I'd recommend to use/upgrade to the ZoL 0.6.1 release for Debian, that comes with an actually working automount script (at least I had no problems so far with it). Or arrange startup order so PVE startup scripts start after the zfs script in init.d. In short, make sure the zfs root dir is empty when mounting your zfs datasets.
