Using PVE 4 with ZFS and LXC

[rflaherty]

I just fired up a new ProxMox PVE 4.0 server with ZFS and followed the proxmox instructions on how to restore my OpenVZ containers to it. I scp'ed the file over to /var/lib/vz/dump and then attempted to restore it using the pct restore command, but I get an error:

Allocating group tables: 0/64 done
Writing inode tables: 0/64 done
Creating journal (32768 blocks): done
Multiple mount protection is enabled with update interval 5 seconds.
Writing superblocks and filesystem accounting information: 0/64
Warning, had trouble writing out superblocks.TASK ERROR: command 'mkfs.ext4 -O mmp xxx-disk-2.raw' failed: exit code 144

I created a ZFS Rpool on my local ZFS storage, but I am unable to restore the VM onto the ZFS pool. Trying to upload a backup to the pool throws an error "cannot upload to zfs pool". How can I restore my VM to the ZFS pool? Mods: I am new here so feel free to move this thread if needed.

Please upload the backup file to local storage, and specify the zfs storage only when you restore.

I am using the command "pct restore", what option to I have to append so that I can specify the storage location. Essentially, it creates the .raw disk image file on local storage, but fails to create the disk. I also cannot upload a backup to the local storage via the Web GUI, it gives the error "cannot upload, file type backup not allowed"

I will also note that the ZFS pool does not show up as an option even when creating LXC container from a template.

You need to allow backups on local storage (configure storage content).

templates and backups are tar files, and needs a directory storage (for example 'local' storage).
