I believe that there are some limitations on booting FreeBSD from
filesystems bigger than 2Tb, but I know of no limitations on building
non-root filesystems bigger than 2Tb. I have copied Kris Kennaway
and the FreeBSD filesystem mailing list in the hope that someone
can give a more precise answer than me.

Hello,

Wikipedia says that you contributed to development of FFS and I
thought you might give a sure answer to a question about it.
These days I saw a question on freebsd-questions mailing list that was
left without a solution till now [see below].

Is there any chance that FFS can be extended to handle larger disks?

Best regards.

Hello

I'm trying to install FreeBSD 6.2 on a HP DL320s. This server has a P400 RAID
controller with 12 SATA disk drives attached to it. The RAID controller is
supported in FreeBSD through the ciss driver.

The problem happens when i try to use a RAID larger in size to 2 Terabyte,
then the install program freezes and the machine reboots (it cannot find the
disk). If the array is smaller than 2 Terabytes then there is no problem, the
controller detects the disk and i can install FreeBSD on it. I have tried
with i386 and AMD64 versions (the server has a Xeon processor supported by
AMD64)

Any clue on how to solve it? FreeBSD can't be installed on disks larger than 2
TB?

Thanks
