При загрузке Linux на этапе виполнения Checking root filesystem выдает предупреждение не находит файловую систему.
WARNING: Your /etc/fstab does not contain the fsck passno field. I will kludge around things for you, but you should fix your /etc/fstab file as soon as you can. /:
The superblok could not be read or does not describe a correct ext2 filesistem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate suberblock: e2fsck -b 8193 <device>
Подскажите каким образом могу восстановить файловую систему. Заранее благодарен.
