Pvcreate worked fine:

This happens with either of the two partitions.

Neither partition is allocatable.
Since the volume group was never created, there's nothing here:

take a while...
vgscan Finding all volume groups
vgscan Wiping internal VG cache
NOW...the kicker here is that I also have Mandriva 2006.0 installed on the
same machine. It was able to create the physical volumes and the volume group
without any problems, and thereafter the logical volume, which formatted (under
jfs) and mounted.
So it appears there is a bug in pvcreate (or maybe vgcreate)???
Thanks -
