I have reviewed many faq's and searched the mailing list archives but
found nothing.
I am currently in the process of a major upgrade from an existing
system that has been in collocation for three years, openbsd 3.5 with
Pentium 3 hardware and 400gb total storage. The system hardware
replacing it will have a hardware sata raid controller, and the
original plan was to present the Array as one 2.1tb drive to Openbsd
3.8. The initial headache was obtaining all the hardware.
Reviewing documentation revealed this gem:

Is this hard limit because of issues with the filesystem? Would it be
possible, limitations with the controller aside, to present the array
as three 700mb slices and combine them with CCD? Or would I be faced
with the same limitation because of the large disk size.
The array is running raid 5 which is the reason for the large disk size.
I am really stuck on this problem as Openbsd is my primary OS choice,
but this is a deal breaker and I would like to explore all options
before having to move to another OS.
Thank you for your time.
