NFS Version 4.0 Trunking Update
Abstract
In NFS version 4.0, the fs_locations attribute informs clients about
alternate locations of file systems. An NFS version 4.0 client can
use this information to handle migration and replication of server
file systems. This document describes how an NFS version 4.0 client
can also use this information to discover an NFS version 4.0 server's
trunking capabilities. This document updates RFC 7530.
