Except that the lvm that's being run now is NOT on sdb.  Observe: 

[frankcox mutt ~]$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      450G  192G  235G  45% /
/dev/sda1             190M   22M  159M  13% /boot
tmpfs                 2.0G  476K  2.0G   1% /dev/shm

As you can see, there's a difference between what's being reported and what's
actually being used.  sda seems to be "lost" but it's the one that's in use.

Since all of my "stuff" is currently on the 500gb drive, and it's what I'm
using right now, I would like to either keep it as-is and set up a new volume
that I can actually use on sdb or extend my currently in-use volume to use the
space on sdb as well.
