Dear People,
I must be missing something obvious, but I'm having problems with basic
commands on Debian Sarge, using lvm2.
I installed lvm2 and dmsetup. I'm using the stock Debian kernel 2.6.8-2-386.
I can do basic manipulations using /dev/hda1, but not with /dev/hda2.
This is on a very ordinary Dell Optiplex, normal x86 architecture.

All good so far. However.
[EMAIL PROTECTED]:/dev/mapper# pvdisplay /dev/hda2
No physical volume label read from /dev/hda2
Failed to read physical volume "/dev/hda2"
[EMAIL PROTECTED]:/home/faheem# vgextend testvg /dev/hda2
No physical volume label read from /dev/hda2
/dev/hda2 not identified as an existing physical volume
Unable to add physical volume '/dev/hda2' to volume group 'testvg'.
Any idea what is going on here? This is a new installation, and only has the
bare bones on it.
Please cc me on any reply. Thanks in advance.
Faheem.
