In the interest of this thread I tried to duplicate the problem. I
created:

Which I can newfs and mount

(root@charon) /etc# mount /dev/gvinum/test /mnt
(root@charon) /etc# df -h
Filesystem                 Size    Used   Avail Capacity  Mounted on
/dev/ad4s1a                357G    119G    209G    36%    /
devfs                      1.0K    1.0K      0B   100%    /dev
172.0.255.28:/data/unix    1.3T    643G    559G    54%    /nas1
/dev/gvinum/test           148G    4.0K    136G     0%    /mnt

But with /dev/gvinum/test unmounted if I try:

(root@charon) /etc# geli init -P -K /root/test.key /dev/gvinum/test
geli: Cannot store metadata on /dev/gvinum/test: Operation not
permitted.  
(root@charon) /etc#

My random file was created like 

dd if=/dev/random of=/root/test.key bs=64 count=1

I use GELI at home with no trouble, although not with a gvinum volume.
