This code is now in CVS for testing.

It lets you restrict the PEs you want to move. 
Can only move off one PV at once (ie. only one cmdline arg).

And of course you can still restrict the PEs available for allocation
by listing them afterwards, and/or use -n to restrict the PEs
moved to those belonging to a specific LV.

pvmove /dev/sda2:1000-1999 /dev/sdb1:1000-1499:2000- /dev/sdc1:500-1000
