I knew there had to be a more sensible way. :P

Hi all,
a quick question. I have a DRBD resource that was once used as a
drive
for a Linux machine that used LVM. I want to create a new VM (KVM
based) that uses this resource. I can start the installation OK
- the
installer 'sees' the 300GB drive (/dev/drbd/by-res/<resource>)
but when
I try using the partition manager in the Debian (guest) installer it
complains that there is already LVM data on there and it won't
allow me
to use the drive without first cleaning up the LVM config on there.
Is it possible to mount the resource in the host and use the command
line LVM tools to 'clean' that up? I was thinking that maybe I could
use *dd* to clone a new clean resource of the same size but that
seems
silly.
Does anyone have any suggestions for 'formatting' this resource
so that
it looks again like a clean un-partitioned disk?
Thanks in advance.
Simplest would be to write zeros to the device;
dd if=/dev/zero of=/dev/drbd/by-res/<resource> bs=4M
If you know that the LVM metadata is at the first or end of the drive,
you can limit the dd to count=X or use of offset to hit the end of the
resource.
