You have to unmount the volume in RHEL 3.

It may be necessary to log in as root (no sudo!) or reboot into single 
user mode to unmount a volume.

   # umount /dev/Vol01/<vol>

Do a forced filesystem check

   # e2fsck -f /dev/Vol01/<vol>

Extend the file system to new size

   # sudo resize2fs /dev/Vol01/<vol>

Remount the volume

   # mount /mount/point

Resizing a volume while still mounted requires a 2.6 kernel, lvm2-2.02 
and above, e2fsprogs 1.39 and above
