NFSv4.1 Update for Multi-Server Namespace
draft-ietf-nfsv4-mv1-msns-update-01
Abstract
This document presents necessary clarifications and corrections
concerning features related to the use of location-related attributes
in NFSv4.1. These include migration, which transfers responsibility
for a file system from one server to another, and facilities to
support trunking by allowing discovery of the set of network
addresses to use to access a file system. This document updates
RFC5661.
