Well , Thanks for your suggestions.
1.Which kind of file system is being used on the volume having trouble? A: it uses the ext2fs filesystem on CentOS 4.6 x86_64
2.Do you have backups? A: that server is used to backup other servers data , so itself has not any backups
3.Is the volume small enough and do you trust yourself enough with dd to duplicate it off to a USB|firewire|esata disk? (now THIS _is_ risky. :)
4.have you read `man fsck` to see why it was being suggested to run it WITHOUT the a or p options? A: Yeah ~ I have read that . In particular , "-p" options ,. This option is mainly provided for those sysadmins who don't want to repartition the root system to be small and compact( which is really the right solution)
You are either going to have to run fsck and answer 'y' to whatever it suggests or learn more than it knows about fixing filesystems.
