Heh, Sorry Zac - should've payed more attention to what I was typing...

pvscan -- ACTIVE    PV  "/dev/cciss/c1d0p1" of VG "Volume0" [99.99 GB / 99.99 GB Free]
pvscan -- ACTIVE    PV  "/dev/cciss/c0d0p2" of VG "Volume0" [136.61 GB / 68.89 GB Free] 

I need to remove /dev/cciss/c1d0p1.
pvscan shows that its unused, but a "vgreduce Volume0 /dev/cciss/c1d0p1"
tells me it can't reduce because the PV is used.

Any ideas?
