During install, you can do custom partitioning. You may want to
create more then one volume group, depending on how you plan on
using the drive. Or you can skip the creating of volume groups, and
just use disk partitions. But if I remember correctly, you are
limited to 16 partitions with the current drivers.
If you have already installed, and want to change sizes, I would
boot off a live CD and use Logical Volume Management from the System
--> Administration menu to change things.
Do not meddle in the affairs of dragons,
for thou art crunchy and taste good with Ketchup!
