" 1. use fdisk create a new primary partition using the available open space.
For this example it would be /dev/sda3.
2. pvcreate /dev/sda3 to set it up
3. vgextend /dev/VolGroup00 /dev/sda3
4. do a vgdisplay and see how many open extents you have on VolGroup00.
For this example assume 407 extents are open
5. lvextend -l +407 /dev/VolGroup00/LogVol00
6. resize2fs /dev/VolGroup00/LogVol00 (assumming ext2/ext3)"
