As I understand it, there is no FreeBSD VFSop that returns the maximum
file size supported. As such, the NFS servers just take a guess.
You can either switch to the experimental NFS server, which guesses the
largest size expressed in 64bits.
OR
You can edit sys/nfsserver/nfs_serv.c and change the assignment of a
value to
maxfsize = XXX;
at around line #3671 to a larger value.
I didn't check to see if there are additional restrictions in the
clients. (They should believe what the server says it can support.)
