Yes, that should work just fine.
The NFS server acts as a Gluster client. So, on one side the NFS-server
speaks the standard NFS protocol to the clients, on the other side it
talks to the bricks in the volume. The logic of the distribution and
splitting of data is done inside the NFS-server (by libgfapi in
FSAL_GLUSTER for NFS-Ganesha).

Thanks, I understand it. Now I am trying to export a volume through
nfs-ganesha but have a question again.
In the EXPORT block in ganesha.conf, for the export path I need the
enter the full path to gluster volume.
So this means that I need to mount the gluster volume on the server
right? Currently I don't have gluster volume mounted on servers.
If this is true each server also will be a client right?
