Hi,
I'm new to the list and new to the use of LVM. I have read the manuals 
(which mainly are for LVM1) and am using LVM2.
I have one question. I just created a new volumegroup on an USB external 
disk.
As the manual says I did : pvcreate /dev/sda but that did't work but 
pvcreate /dev/sda1 worked.
I then did a vgcreate VG01, expecting to get one volume group for the 
whole disk (250 GB). However, it created 2 volumegroups, one named 
VolGroup00  of 46.6 GB and one VG01 (as expected) of 232.8 GB. The 
problem is I have on another 2 disks already a VolGroup00 so I cannot do 
an lvcreate VolGroup00 as this will try to access the earlier created one.
Can anybody explain why an unrequested volumegroup is created and how 
can I solve this.
I cannot do a vgdelete VolGroup00 as this will destroy my current - 
working - system.
Hope somebody knows the answers.
Thanks
Joep
