I'm guessing here, but it sounds to me like the _partition_ has been
enlarged, but the file system on the partition has not been enlarged.
As far as I know, ReiserFS and ext3 can be enlarged on the fly (ie.
with the filesystem mounted) but some (most?) filesystems can only be
resized while unmounted.

For ReiserFS, the command I think you want is resize_reiserfs, and for
ext3 it's resize2fs.

If you need to enlarge the filesystem with it unmounted, you'll need
some kind of LiveCD or rescue disk to get a running system without
mounting /.

HTH,
Ian
