The IESG has approved the following document: - 'Parallel NFS (pNFS) Flexible File Layout' (draft-ietf-nfsv4-flex-files-19.txt) as Proposed Standard This document is the product of the Network File System Version 4 Working Group. The IESG contact persons are Mirja Kühlewind and Spencer Dawkins. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-nfsv4-flex-files/ Technical Summary This Internet-Draft introduces the Flex File Layout Type to extend parallel NFS (pNFS). This layout type allows for the control protocol to be defined in another I-D or to be the NFS storage protocol. This I-D details the interaction of the new layout type with both NFSv4.1 and NFSv4.2 metadata servers. It also introduces client-side mirroring for the replication of files. Working Group Summary The WG had no major issues during the WGLC. The new layout type is implementable. There are several client and server implementations already interoperating based on the I-D. Document Quality This Internet Draft reviews and clarifies the requirements for creating a new Layout Type. It uses the three existing Layout Type specification as case studies to show that the requirements were issues considered during the creation of earlier Layout Types. I.e., it captures the relevancy of the requirements. The content of this document has received quality feedback and review throughout its life. Personnel Spencer Shepler (NFSv4 WG co-chair) is the document shepherd Spencer Dawkins is the Responsible Area Director.
