Hmm. There is a manpage in 6-STABLE. And there are a few things that
don't work but I wouldn't call it "lots".

That's a bug; I think it might be related to compiling gvinum in the kernel
as opposed to loading it from /boot/loader.conf. I also think there is a
fix already commited to 6-STABLE.

I'm succesfully running gvinum RAID-5 on two plexes on the same
machine since 6.0-RC3 or thereabouts. I just used the same procedure I
used to setup volumes with "regular" vinum. I did not try to migrate
volumes however, I started from scratch and restored my data.

Two things:

- contact Lukas Ertl <le at FreeBSD.org> and/or send PRs with any problems
  that you encounter. He is very responsive, especially when you send
  in detailed problem reports.
- try 6-STABLE instead of 6.0-RELEASE. It might not be useful for you
  in production, but at least you get a manpage, and the disappearing
  volume bug might be fixed. If not, you can try option 1.

HTH,
