You're not supposed to expand LVM physical volumes, you create new ones
and add them to the volume group. Make sure you create partitions on the
array, don't pvcreate it as a whole disk. After expanding the array the
disk (/dev/sda or whatever) should have free space at the end. You would
create another partition in the new space, pvcreate it, and extend the
volume group on to it.
