I'm running into trouble here, getting the lvm scanning tools to notice PVs I have created on entire disks, like this:
pvcreate /dev/hdd
Some output:

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 PV /dev/loop0 VG media_vg lvm2 [111.79 GB / 0 free] PV /dev/loop1 VG media_vg lvm2 [186.31 GB / 0 free] Total: 2 [298.10 GB] / in use: 2 [298.10 GB] / in no VG: 0 [0 ]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 Klaus
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?
