If you only have FreeBSD installed on the box or if you don't need
slices/partitions you can just do newfs /dev/xxx (dedicate).
vinum should not be used on 6.x and above, gvinum (GEOM + vinum)
replaced it but I'm not sure if it's still actively
supported/developped .. (?)
Also, take a look at gconcat and unionfs.
