Hi Andreas,

I think I posted exactly the same quiestion to the list some time ago.  The
answer is that you need the Device Mapper Mirror Target compiled into (or as a
module in) your kernel.  You will need to get the "unstable" patches from the
following URL:

http://sources.redhat.com/dm/patches.html

Feel free to mail me if you need any more info on this.

Rupert

Erm...the mirror target is available in 2.6.8.1 now I believe - you just need
to make sure it's enabled in your .config when you compile your kernel.  I
believe the dm-mirror target is all that's required for pvmove.
