[linux-lvm] cannot create a volume group named the same as one already removed

[Tom Georgoulias <tom.georgoulias@motorola.com>]

I'm using lvm 1.0.3 that came with my Red Hat 7.3 system, with kernel 
2.4.18-24.7.x.  When I try to create a volume group that has the same 
name as one that existed in the past but was removed, I get an error 
stating that the volume group already exists and to use a different 
name.  What can I do to fix this?

I appreciate any tips.  Most of the command outputs are below to help 
illustrate what I'm seeing/doing.

[root@mom root]# vgcreate volgrp2 /dev/hdg
vgcreate -- volume group directory or file already exists
vgcreate -- please choose a different name

[root@mom root]# vgremove volgrp2
vgremove -- volume group "volgrp2" doesn't exist

Before I tried recreating this group, I removed all of the LVs from it:

[root@mom root]# df -hl

The new disk was been initialized:
[root@mom root]# pvdisplay /dev/hdg
pvdisplay -- "/dev/hdg" is a new physical volume of 114.50 GB

And volgrp2 isn't active:
[root@mom root]# vgdisplay
