[linux-lvm] How do I use free PE?

[Rod Rook <rod rook gmail com>]

I've installed Fedora 10 on a 250GB SATA hard drive. 
I want to use the unused portion (free PE= 4378, about 140GB), but I don't know how I go about doing it.
I don't want to add it to VolGroup00, but I want it made accessible as a general storage space. 

> [root localhost Documents]# pvdisplay /dev/sdb2
