The IESG has approved the following document: - 'NFSv4.0 migration: Specification Update' (draft-ietf-nfsv4-rfc3530-migration-update-08.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-rfc3530-migration-update/ Technical Summary The migration feature of NFSv4 allows for responsibility for a single filesystem to move from one server to another, without disruption to clients. Recent implementation experience has shown problems in the existing specification for this feature in NFSv4.0. This document clarifies and corrects RFC7530 (the NFSv4.0 specification) to address these problems. Working Group Summary This I-D represents strong working group consensus and is derived from implementation experience of the NFSv4 migration capabilities and is therefore representative of needed clarification in specification for interoperable implementation. Document Quality As mentioned, this work is derived from implementation experience and relates to the needs of the community of NFSv4 implementors such that they can create effective and interoperable implementations in the context of migration support.
