Is it possible to recover the corrupted img?
ty in advice

 

[dietmar]

you can try to check/repair the image using

# qemu-img check ...

see man qemu-img

I tried but i got those errors:

qemu-img check /var/lib/vz/images/106/vm-106-disk-1.qcow2
qemu-img: Check failed: Cannot allocate memory

and

qemu-img check -r all /var/lib/vz/images/106/vm-106-disk-1.qcow2
qemu-img: Check failed: Cannot allocate memory


I have no idea what does can not allocate memory means because the machine I'm running those commands have:

free -h
total used free shared buffers cached
Mem: 62G 45G 17G 53M 206M 42G
-/+ buffers/cache: 2,7G 60G

and
