How does LVM deal with physical disks that can get bigger or smaller,
such as a hardware RAID device? What happens to a PV on a hardware
RAID-5 device that is presented to the system as a single (say scsci)
target when you put a few more disks in it and tell the hardware raid
device to add them to the given (scsi) target that a PV was created
on? (what a mouthful).
Is this really possible or can one only expand a hardware raid array
for LVM usage by adding additional raid targets and then adding the
raid targets as PVs to a VG?
