It's probably because you cannot create bsdlabels or fdisk partitions larger than 2 TB. The sizes you're seeing are probably because of overflows in calculations. It's not that the OS doesn't support larger drives, the problem is the partition formats. You might succeed by creating two large partitions, one ending just before the 2 TB limit and one stretching the rest of the space, but a more robust way would be to either create two smaller volumes (if the controller supports creating them on the array) or you'll need to install FreeBSD on a separate, smaller array and partition the large array with GPT (or use ZFS). --------------enig74292645D45E2B768062CBEF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJPPjIldnAQVacBcgRAsk4AJ9ksMLD9Lv3EGUvOnq7M6oShfCRcACdELzK qjV5bCDbIYvDA2Ichhs3Wck= =J7g8 -----END PGP SIGNATURE----- --------------enig74292645D45E2B768062CBEF--
