CHECKING ROOT FILESYSTEM

(i.e.,without -a or -p options)
It means that the root file system is corrupted
how can i fix it?

First try to boot it into single user mode, and do preceisely what it's telling you ('fsck -r /dev/'. Use 'mount' to find out what that is).

Fix whatever issues it's got.

If it wont allow you to do that, find a bootable linux CD with a 'rescue' or 'repair' mode, and do the fsck from there.

This will hopefully fix the issue.

Even if you'll be able to boot your system after running fsck, I strongly recommend to check system logs - maybe your harddisk going bad. In this case you should urgently transfer your linux to a new disk.

looks like a disk failure to me too.

run the system in single user mode. and run fsck command and fixed the error. and take the backup on another disk drive. This is seems tobe disk failuer.

Hi

I guess you need to check your disk. Download few HE check utilities from net and try to diagnose your disk.

Booting to single user mode is the correct
way to correct this. FSCK manually.

This is not an unutual occurance using
an unjournaled file system (EXT2).

Once you are up and running consider:
- Check the rc script for the mount and
see if you can set a flag to automatically
fix errors during booting.
- If supported, consider making your root
file system journalled. (EXT3). This
will reduce the likelyhood of such failures
in the future.
