Help with an LVM2 server?

[G Mc.Pherson]

Hi Folks,

I recently upgraded my server here at home. This server currently has 3 
hard drives operating under LVM2 and formatted as JFS and I'm trying to 
add a 4th drive (/dev/sda1). The problem is that the howto at 
http://www.tldp.org/HOWTO/LVM-HOWTO/recipeadddisk.html talks about ext2fs.


After fooling around, I managed to get vgdisplay to report the following:

--(cut here)--

   --- Volume group ---
   VG Name               archive
   System ID

   VG UUID               dTVTyh-4P0j-aKmx-M8WW-eQNY-VKon-OMrGkY

Note that the VG Size is reporting 745.23GB, however when I
issue a 'df -h', I get the following report:

--(cut here)--

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/pvr
                       513G  288G  225G  57% /home/pvr
root at vsrv:/home/pvr#
--(cut here)--

The question is, it appears that I'm missing 232GB, which sounds 
reasonable as the additional drive is a 250G?

Can anyone help?
