I see that is a new feature in the lvm2 tools in the upstream providers Update 
4. Tried to google up some info, but it all drowns in md mirroring and old info. 
Hope they have implemented 3-way mirrors, on-the-fly increase and reduction of 
mirrors. Like you have in AIX LVM. Too bad it was based on HP-UX LVM originally, 
but that is water under the bridge.

With LVM, it is pretty easy to do mirroring, since all you have to do is map 
more than one PE to each LE. I'm looking forward to test this feature. It could 
also deprecate utilities like pvmove, since you would not really need it anymore.

The worst that can be said is that he's an underachiever.
