take sdb as newly added disk

Step1: Format new disk and label as LVM disk
fdisk /dev/sdb
n -> p -> 1 -> return twice -> t -> 8e -> w

Step2: Create FS on new disk
mkfs.ext3 /dev/sdb1

Step3: Create as PV
pvcreate /dev/sdb1

Step4: Extend existing VG to new disk
vgextend VolGroup00 /dev/sdb1
then, you will get more free space now. check with:
vgs

lvextend -L +total_space_for_vol_g /dev/VolGroup00/LogVol00
lvextend -L +space_number_to_add_g /dev/VolGroup00/LogVol00
