I don't think those commands will work on ext3

[root@HF-LINSRV01 i386]# e2fsck -f -y /dev/data/cpanel002
e2fsck 1.39 (29-May-2006)
Couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open 
/dev/data/cpanel002
The superblock could not be read or does not describe a correct ext2
filesystem.  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 superblock:
   e2fsck -b 8193 <device>
