Hi John,
In short; No.
I believe the most common, practical method to achieve some sort of data
protection is to have your devices in a RAID array with the LVM
configuration on top. You're probably already aware, given that you
mentioned 'dm', but this method means the mirroring is abstracted out
from LVM and handled by the dedicated processes.
Sorry that wasn't a great help, but thought I'd share. I'm actually
considering the best approach myself in preparation for rebuilding my
file-server, and I found (oddly enough) a very informative Slashdot.org
comment thread on the general subject:

Good luck!

Hi.
I was wondering if current releases of LVM2 included mirroring support
in the actual logical volume manager itself ('native' mirroring
support), without the need for any other external mirroring solutions
(like for example 'dm') ?
Sincerely,
John Smith.
