Saving files from an qcow2 image of an ext4 partition

[sail3006]

Hi I am new to proxmox and Linux in generall...
I have an Openmediavault VM and i used to have an ext4 formated HDD drive. Before i switched to ZFS i saved the qcow2 image of this partition. Now that i have formated the HDD to the ZFS file system i need to retriev the data from the old EXT4 partition.
How can i do that? is there a way to mount the qcow2 file as a virtual hard drive to proxmox?

You can mount a qcow2 directly on a path:

• loading the kernel module: modprobe nbd
• connect FILE to the local NBD device DEV: qemu-nbd -c /dev/nbd0 <path to your qcow2>
• mount the qcow2 to a path you would like: mount /dev/nbd0p2 <mountpoint>
• Do your things...
• Unmount: umount /mnt/tmp
• Disconnect the device: qemu-nbd -d /dev/nbd0

You can also import a qcow2 directly:

qm importdisk <vmid> filename.qcow2 <storage name>
