Unable to create a physical volume on a whole disk

Hi Jan,

Quoted 5 lines

I would like to create a pv on a whole disk but pvcreate gives me the message that there is a "partition table" on the disk.

gw:/dev# pvcreate /dev/hdb
pvcreate -- device "/dev/hdb" has a partition table

I think what teh message from pvcreate means is that this is a device with a partition table, and pvceate isn't supposed to be used on such devices with partition tables, but only on partition-like devices. I think pvcreate doesn't care whether the partition table is valid or not; it only cares about the type of device.

I would suggest that, to use the space on a whole disk as a physical volume, you try:

- Making just one partition of the whole disk space, with fdisk or other partitioning tool of your choice; that will normally be /dev/hdb1
- Making a physical volume in that: pvcreate /dev/hdb1
