+ <p>Parallel NFS (pNFS) is an extension to the NFSv4 protocol that
+ allows for file accesses within a single logical mount to be
+ performed against multiple file servers, with the potential
+ for data access to occur in parallel. The pNFS
+ "layout" in use specifies how the division occurs, with
+ metadata operations occurring against the main server, and
+ bulk data operations (read/write/setattr/etc.) occurring via
+ a layout-specific scheme between the client and data
+ servers.</p>
+
+ <p>My first attempt at a pNFS server using GlusterFS was a dud.
+ It worked, but performance was so poor that it was not
+ usable. This attempt that I call "Plan B", only
+ uses &os;, with one &os; server handling the metadata
+ operations and multiple &os; servers configured to serve
+ data, is now ready for third party testing. If testing by
+ third parties goes well, I anticipate the code will be
+ merged into &os; head in time for &os; 12. Fairly
+ recent &os; or Linux systems should be usable as pNFS
+ clients for testing. This server supports the File Layout,
+ which is supported by both of these clients.</p>
+
+ <p>There is no support for the Flex Files Layout or mirroring
+ at this time. I hope to use the Flex Files Layout to add
+ mirroring support over the next year or so. Striping is not
+ supported, and I have no plans for implementing this at the
+ moment.</p>
+
+ <p>The patched &os; sources may now be accessed for testing
+ via either Subversion or download of a gzipped tarball.
+ They consist of a patched kernel plus nfsd daemon and can be
+ used on any &os; 11 or later system.</p>

+ <task>Testing by others will be needed, now that the code is
