   You are aware that there's a real in-kernel ZFS implementation under 
Linux now, right?  See http://zfsonlinux.org/.  I've done some very 
basic testing with it, and so far, it works.  Going through FUSE is 
slower than pissing tar; this implementation won't have that problem.

   FUSE is useful for many things.  Performance-sensitive filesystems on 
production servers is oh-so-NOT one of them. ;)
