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
