Why not just use pvmove to move the extents off the two original PVs and
onto the third? The end result is the same (and internally it's not
dissimilar - pmove creates a temporary mirror volume to do its work) but
it's less manual work and should be more robust as pvmove does
checkpointing that allows the process to be interrupted and restarted.
