The mount point needs to exist prior to mounting a filesystem so, try
something like this (as root):

mkdir /test
mount /dev/gvinum/test /test
mount | grep test

That last one should produce the following output,

/dev/gvinum/test on /test (ufs, local, soft-updates)

which indicates that you have a mounted filesystem on /test.

Ya, documentation is still being worked on. For basic stuff (like creating
concatinated volumes) you can use the vinum documentation and replace
'vinum' with 'gvinum' when you try things. Using your 'test' filesystem is
a very good idea. Some aspects of vinum still aren't fully implemented in
gvinum.

Remember, if you just created your /test volume. It should be empty. You
did run 'newfs /dev/gvinum/test' after creating it and before mouting it,
right?
