Hello! Faced the following problem. After a correct restart of the server, one of the virtual machines did not boot. Bootloader not found. The machine disk was stored on LVM as a RAW file. After booting from LIVECD, fdisk and gparted saw the disk as unrecognized by the volume label. Can't mount the disk on the host server mount / dev / mapper / VM01-vm - 3000 - disk - 1 ./mnt mount: ./mnt: wrong fs type, bad option, bad superblock on / dev / mapper / VM01-vm - 3000 - disk - 1, missing codepage or helper program, or other error. Moreover, I tried to restore from daily backups of a weekly depth, they all behave in the same way
