It is probably not a bug... most likely you have additional filesystems that need checking.  If you are unsure about what filesystems to check, use the "-A" flag to fsck:

# fsck -A

That will check all applicable filesystems listed in your /etc/fstab file.

It is also possible that the filesystems are too severely damaged to be repaired from single user mode.  In that case you'll need to download a Centos CD and use rescue mode and hope that you can recover.

Thank you for your reply . I have received my CentOS server as pre-installed , with no CD accompanied . Is there any other way to fix the bug?

Thank you
