Well that's odd, I know they're there. Lets try this:
root@end root # losetup /dev/loop0 /dev/hda
root@end root # losetup /dev/loop1 /dev/hdd
root@end root # pvscan

Hi Miles,
the disks hda and hdb obviously are partitioned (they are shown as
/dev/hda1 and /dev/hdb1), so don't trying to detroy these partitions,
he doesn't know what the contents of, is good behaviour of lvm, isn't
it ;-).
Ciao

So, you're saying that although the lvm PVs are _not_ on partitions, the
disklabel still describes some partition on the disk, so lvm is ignoring
the disk as a whole as a possible PV?
That's what it looks like, i'd guess lvm will use your whole-disk PVs if
you get the partition table cleared. Without this, he'd destroy
partitions of unknown types.
Ciao
Klaus
