>How-To-Repeat:
Install FreeBSD on to a machine/array configured over 2TB in size.

Reconfiguring the array to a 2x400GB mirror (which now holds /, /usr and /var) and a 6x400GB raid5 dropped the array disk size down to 1.8 and allowed sysinstall to format it and then I just shoved it in to fstab manually.  An annoying work around, but for now I'll live.
