(1) 1.0.1 is pretty badly out of date; suggest updating to
    1.0.6 or 2.X.

(2) Running pvcreate on a full device (e.g., /dev/hda) then
    again on /dev/hdaX will end up overwriting a portion of
    the contents in your first PV with the second one. LVM
    did exactly what you wanted it to. How is the a bug.
