$/dev/mapper/sda1 not identified as an existing physical volume

[krajschmitz]

I'm running Ubuntu 9.04 Server w/o gui.
My original is
$sudo vgextend volumegroup /dev/sda1
$/dev/mapper/sda1 not identified as an existing physical volume
$Unable to add physical volume '/dev/mapper/sda1' to volume group 'volumegroup'.

$sudo vgextend --version
$LVM version: 2.02.39 (2008-06-27)
$Library version: 1.02.27 (2008-06-25)
$Driver version: 4.14.0

If it helps
$sudo fdisk -l

What exactly do you want to do?

[krajschmitz]

I wanted to extend my volume group to include my second hard drive

[krajschmitz]

I solved the problem.

I solved the problem!?! that's it? no explanation of how.

I'll submit that you probably forgot to do a pvcreate on the device first.

I had the exact same problem and found this thread but figured out what was wrong...
