You'll need to use GPT partition instead of MBR if you're trying to boot
with a size > TB. AKAIK, sysinstall doesn't support this, requiring a more
"hands on" installation.
If you haven't considered it, it may be worthwhile to use ZFS. In that
scenario, you'd want to the controller to present the disks as JBOD and use
RAIDZ. Once again, sysinstall doesn't support this, but there are some good
FreeBSD wiki articles on it.
