Sven, if seems like 90% of the gvinum commands don't work ... they just 
yield "unknown command" which isn't helpful.  Three questions would help 
me, so I'll ask them.

1) how do I erase the existing screwed up config?  Reconfig is naturally

volume/plex size remains 0.  Again, "attach" isn't recognized).  The
