Internet Engineering Task Force (IETF) D. Noveck, Ed. Request for Comments: 8881 NetApp Obsoletes: 5661 C. Lever Category: Standards Track ORACLE ISSN: 2070-1721 August 2020 Network File System (NFS) Version 4 Minor Version 1 Protocol Abstract This document describes the Network File System (NFS) version 4 minor version 1, including features retained from the base protocol (NFS version 4 minor version 0, which is specified in RFC 7530) and protocol extensions made subsequently. The later minor version has no dependencies on NFS version 4 minor version 0, and is considered a separate protocol. This document obsoletes RFC 5661. It substantially revises the treatment of features relating to multi-server namespace, superseding the description of those features appearing in RFC 5661.
