You probably didn't disklabel the disk.  Do a "man disklabel".  In
particular, you should do:

   disklabel -w /dev/vinum/??? auto

Edit the disklabel:

   disklabel -e /dev/vinum/???

Then newfs:

   newfs /dev/vinum/???

Note that you can potentially trash the system with all this, so please
read the section in the handbook on setting up vinum and/or disklabels
before doing this on a production system.  In fact, test on a scratch disk
first.
