Yes, but if you use v3 or v4 it's larger than you care about.

That also matters. You need to have a server OS which supports
large block devices, and the filesystem needs to support it also.
Obviously, XFS does (except it can't export more than 2^32 inodes
currently).

Yes. Don't use NFSv2.

This comes down to large block device support. You need to use 2.6
or apply the LBD patch to 2.4.

Yes. Our sales staff will be happy to sell you one, and as many TB
of disk as you can afford.
