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
