The MBR format is limited to a 32-bit number of sectors. Given
512-byte sectos, it cannot handle values larger than 2TB. However,
this doesn't matter if you don't want to share the disk with other
operating systems. In disklabel(8), simply set the OpenBSD disk
boundaries 'b' to the real size '*'; see the man page.
Here's the partition info I put on a 3TB disk:
# fdisk sd1
