Technical Summary
The Parallel Network File System (pNFS) Flexible File Layout allows
for a file's metadata (MDS) and data (DS) to be on different servers.
It does not provide a mechanism for the data server to update the
metadata server of changes to the data part of the file. The client
has knowledge of such updates, but lacks the ability to update the
metadata server. This document presents a refinement to RFC8435 to
allow the client to update the metadata server to changes on the data
server.
Working Group Summary
Agreement was reached across the WG for this draft. This draft was relatively uncontroversial. Nothing has been threatened or no particular conflict present.
Document Quality
There are some significant implementations (in Linux) but not broadly yet
beyond Linux. There is at least one server implementation. The Linux
implementation is part of the kernel mainline, and so included in all
distributions. This is, however, an optional feature.
