why do u want to double ur disk ? i have no knowledge about vinum yet
but some time ago i set up a mirror with linux which doubled the disks
automatically first time i add a new disk to the raid array ... guess
this would be similar with vinum (?)

i am not sure whether u can move partitions/slices in this way. if u
really wonna double ur disk
dd if=/dev/ad0 of=/dev/ad2 is the command i would use (NOT TESTED!)
