Internet Engineering Task Force (IETF) C. Lever, Ed. Request for Comments: 8587 Oracle Updates: 7530 D. Noveck Category: Standards Track NetApp ISSN: 2070-1721 May 2019 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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 7841.
