Checking root file system
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 superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and if really contains an ext2 filesystem (and not swap or ufs or something else), the superblock is corrupt, and you might try running e2fsck with an alternate superblockZ:
  e2fsck -b 8193 <device>

fsck.ext2: Is a directory while trying to open /           [FAILED]

*** An error occurred during the file system check.

我输入 root password 后, 出现:
bash: id: command not found
bash: id: command not found
bash: id: command not found
bash: [:  too many arguments

请问这是怎么回事? 应该如何恢复正常使用?
谢谢
