[NTLUG:Discuss] lvm, vgextend, PV too small

[Robert Citek]

How does one grow a volume group using vgextend 1.0.8?

I've created a volume group foo that contains four 100 MB devices.  I 
then removed one of the devices:
   # pvmove /dev/hda10
   # vgreduce foo /dev/hda10

I now want to add /dev/hda10 back into foo using vgextend.  However, 
I'm getting an error:

   # vgextend foo /dev/hda10
   vgextend -- INFO: maximum logical volume size is 2 Terabyte
   vgextend -- ERROR: physical volume "/dev/hda10" too small for 
physical extent size of volume group "foo"

I've browsed through the man page and googled, but haven't found 
anything directly related to this error message, yet.  I did find a 
nice LVM tutorials, though:

   http://ds9a.nl/lvm-howto/HOWTO/cvs/lvm-howto/lvm-howto.html

The box is running Knoppix 3.4 with vgextend v1.0.8, although I see the 
same error running Knoppix 3.3 with vgextend v.1.0.8.

Any hints in the right direction are appreciated.
