Question

Hi everybody,

i've exported a virtual disk image from my docker host and imported it into a simple Proxmox Linux vm (via shell, qm importdisk ...). Linux finds a Linux partition on the vDisk, but I'm unable to mount it.

When I try to mount it with

mount -t btrfs /dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi6-part1 /mnt

I'll get the following error:

mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdc1, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.

Is there any way to read the contents of a vDSM-Volume outside vDSM? This would be helpfull if vDSM crashes or any other problems happen which prevent booting vDSM to recover data or switch to another NAS platform.

Greetz,
BlackAlpha
