I'm doing a big upgrade on my computer and I tryed to use lv mirroring

As I do with LVM on other OS i thought that after mirroring one could
chose to split the mirrored lv.
I can't find how to do it with LVM2 on Linux.
There is a way?
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.
