Sorry about the premture mail.  Here's the real thing:

~250GB looks like 2^31 sectors to me, ie, the largest int.  I think
it's highly unlikely that Linux can safely manage partitions bigger
than that, as there's just too much code in the kernel and fdisk both
that would need to be unsigned clean, just to reach 500GB.  800GB is
probably out of the question, even on 64-bit processors.  But you
might try it on Alpha or UltraSparc.

I wouldn't bet on it there, though, because there's no reason to
suppose the partition table itself can handle 64-bit ints.

The other possibility would be if you can arrange for the RAID to have
2048-byte sectors.
