snapshot is not a good choise for me. I want to have an identical copy
(like dd) on another identical disk, for fast recovery in case of
failure.
This is what I do with raid hardware, and I would like to know if is
possible to do it with lvm mirroring.
I'm looking also on mdadm to mirror a disk (or partition) but I think it
is not usable when disk is already partitioned and used without mdadm.
Backup is good but is not a good choise in this case, because a full
restore is a long process
Tnx
