Mirroring is software RAID1. What you want looks like LVM snapshots. See LVM HOWTO to see how to create snapshots. A backup may be a good thing to do, too.

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 Ambrogio
