LVM hlasi chyby a filesystem nechce najet. Potrebuju zachranit.

Ahoj. Neco se mi stalo s LVM. Mam na nem dva disky s daty a potreboval bych to zachranit. Tady jsou nejake vypisy

trukinbob:/home/trukinbob# mount /dev/media01_vg/media01 /mnt/media01/
mount: wrong fs type, bad option, bad superblock on /dev/media01_vg/media01,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

File system tam je xfs. Hardisky nemaji partitions, ale dal jsem je rovnou do lvm.

trukinbob:/home/trukinbob# xfs_repair -n /dev/media01_vg/media01
Phase 1 - find and verify superblock...
bad primary superblock - bad blocksize field !!!

attempting to find secondary superblock...
........................................................

.......found candidate secondary superblock...
verified secondary superblock...
would write modified primary superblock
Primary superblock would have been modified.
Cannot proceed further in no_modify mode.
Exiting now.

Po prikazu trukinbob:/home/trukinbob# xfs_repair /dev/media01_vg/media01 se vse opravilo.

Zatim vse vypada OK.
