Right, that is pretty advanced. Good going.

I think one important "trouble spot" is that there is no operation 
yet(?) to create a duplicate of a PV that will not ruin the system 
unless you do pvchange -u and vgchange -u ;-).

It took quite a bit of time for me to realize what was going on ;-).

Is PVMOVE supposed to be a backup task? I don't think so? How are you 
supposed to back something up if you are planning to move your system to 
a new disk?
