Parallel NFS (pNFS) extends the Network File System version 4 (NFSv4) to
enable direct client access to file data on storage devices and bypass the
NFSv4 server. This can increase both performance and parallelism,
but it 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 updates RFC 5663 to add a mechanism 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. [STANDARDS-TRACK]
