[Home Assistant VM corrupted?]

Let's see if you can mount it, from unraid terminal:

modprobe nbd max_part=8
qemu-nbd --connect=/dev/nbd0 /path/to/the/image/test.qcow2

Create a mount point:

mkdir /path/to/the/mount/point/

List the partitions of nbd0:

fdisk /dev/nbd0 -l

Mount the partition (in this example is p1):

mount /dev/nbd0p1 /path/to/the/mount/point/

 

cd to the mount point and do what you need to do.

Once finished:

umount /path/to/the/mount/point/
qemu-nbd --disconnect /dev/nbd0
rmmod nbd

 

This was extremely helpful. I recently had a slowly dying cache drive containing my Home Assistant VM. My "backups" were contained within the VM rather than pulled anywhere else, which in hindsight was as good as no backup. I was able to navigate into the backups and pull them out by following your instructions. I tried Mat W's solution above but with my corrupted cache I can't currently install any VM's and haven't dug for a solution yet.
