will enabling pnfs just be like fhe VFS FSAL with pnfs = "true"? 
otherwise I'll wait for your docs


It is not required . By default , FSAL GLUSTER will use pnfs for nfsv4.1.

Only the thing you used be carefully that , current architecture 
supports single mds and multiple ds.

Also you should required to run  nfs-ganesha daemon(will act as DS) on 
every node which contains brick in the trusted pool.

MDS can be any node inside trusted pool or outside the trusted pool.

For nfs-ganesha , latest source code (v2.2-rc6) need to be used.

Thanks,

    FYI.

    GlusterFS vols can now be accessed via NFSv4.1 pNFS protocol
    (mount -t nfs -o minorversion=1 ...) from nfs-ganesha 2.2-rc5
    onwards.

    Note: one fix is to go into libgfapi to fix up using anonymous
    fd's in ds_write/make_ds_handle() (Avati's sugeestion that
    really helps here).
    Once Jiffin or myself get that fix in, a good large file
    performance can be seen with pNFS vs V4.

    All thanks and credit to Jiffin for his terrific effort in
    coding things up quickly and for fixing bugs.

    Great news!

    I did a quick check in the docs directory i.e.
    https://github.com/gluster/glusterfs/tree/master/doc to see if we
    have any documentation about nfs-ganesha or pNFS and glusterfs
    integration, but did not find any.

    I think without howtos around this will hamper the adoption of
    this feature among users. So if we can get some documentation for
    this, it will be awesome.


    Thanks,
    Lala
    Documentation for glusterfs-nfs-ganesha integration is already
    present  :

    https://forge.gluster.org/nfs-ganesha-and-glusterfs-integration

    http://blog.gluster.org/2014/09/glusterfs-and-nfs-ganesha-integration/

    For pNFS, I will send a documentation as soon as possible.

    Thanks,
    Jiffin
