The current LVM mirror code creates 3 (or more - assume just 2
copies for discussion) pieces: copy0, copy1, log. It is obvious what
should and probably does happen if the PV for copy0 or copy1 goes away.
But what happens if the PV for log goes away? Does it convert to a memory
log? When you reboot, does it do a full sync, like with a memory log?
Which copy is copied from and which is copied to for the sync?
