This is a minor update to change the requirements text for operating systems that don't support the pNFS block layout. Instead of the "SHOULD" requirement to check the GPT for all such systems (that was in the -01 version), the new draft says: Data stored on pNFS block layout storage devices can be better protected by incorporating checks for this GUID into other hosts and systems that do not support pNFS block layouts. If pNFS block storage devices are presented to such hosts or systems by mistake, the check for presence of this GUID can be used to prevent writes that could otherwise corrupt stored pNFS data.

Title : pNFS block disk protection Author(s) : Sorin Faibish Jason Glasgow David L. Black Filename : draft-faibish-nfsv4-pnfs-block-disk-protection-02.txt Pages : 6 Date : 2011-09-27 Parallel NFS (pNFS) extends Network File System version 4 (NFSv4) to enable direct client access to file data on storage, bypassing the NFSv4 server. This can increase both performance and parallelism, but requires additional client functionality, some of which depends upon the type of storage used. The pNFS specification for block storage (RFC 5663) describes how clients can identify the volumes used for pNFS, but this mechanism requires communication with the NFSv4 server. This document adds a mechanism to RFC 5663 that enables identification of block storage devices used by pNFS file systems without communicating with the server. This enables clients to control access to pNFS block devices when the client initially boots, as opposed to waiting until the client can communicate with the NFSv4 server.
