Are you sure you need to defragment your partition? From the Multiple-Disk-HOWTO:
13.2.  Defragmentation

This is very dependent on the file system design, some suffer fast and
nearly debilitating fragmentation. Fortunately for us, ext2fs does not
belong to this group and therefore there has been very little talk
about defragmentation tools. It does in fact exist but is hardly ever
needed.

If for some reason you feel this is necessary, the quick and easy
solution is to do a backup and a restore. If only a small area is
affected, for instance the home directories, you could tar it over to
a temporary area on another partition, verify the archive, delete the
original and then untar it back again.
