>Description:
I tried to create raid5, based on vinum, 12 186.2GB hard drives, it's a little bit more than 2Tb. After creation vinum showed volume size = (about) 1499 Mb. And newfs formatted disk really the same size.

V raid                  State: down     Plexes:       1 Size:       1499 MB

When I decreased length to 199911199744, so length*11<2Tb, 
V raid                  State: down     Plexes:       1 Size:       2047 GB

So, that's ok...
