Unfortunately, MBR and BSD disklabel use 32 bit values, so they are limited to 2TB. GPT uses 64 bit values, but I don't believe that FreeBSD fully supports it. You can see the Big Disk project page  for more information. As a workaround, you may wish redo your RAID configuration so that you have multiple logical volumes (e.g. 2T, 2T, 0.5T).  http://www.freebsd.org/projects/bigdisk/index.html -- Benjamin Lee http://www.b1c1l1.com/
