Hi Samuthira,
you can refer to few below presentations/posts on GlusterFS architecture
and libgfapi -
http://www.gluster.org/community/documentation/index.php/File:GlusterFS_Architecture_%26_Roadmap-Vijay_Bellur-LinuxCon_EU_2013.pdf
http://www.gluster.org/community/documentation/index.php/File:Developing_Apps_and_Integrating_with_GlusterFS_-_Libgfapi.odp
http://humblec.com/libgfapi-interface-glusterfs/
In short -
GlusterFS is a modular and stackable architecture. It has server stack
running on each of the volume bricks processes' and the client stack
loaded in the client applications. The communication between server and
client processes is done via RPC.
So in this case, libgfapi is the module provided by GlusterFS which is
loaded in the client application's (i.e, nfs-ganesha's) userspace when
started and responsible for establishing rpc connections/communicating
with Gluster management and server processes.
Yes. If using libgfapi, FUSE is not required.
I am not sure about how SDFS is designed. Atleast I do not see any
reason why ganesha cannot be plugged to any of the filesystems. You may
just need to mainly work on a library (like libgfapi.so) which when put
in appropriate location, ganesha can load that module and in turn can
communicate with your filesystem.
For any queries on how to plug-in that module for ganesha to use, please
mail to "nfs-ganesha-devel@xxxxxxxxxxxxxxxxxxxxx"
CCin the gluster mailing list who can help you out with the libgfapi
design queries you may have.
Thanks,
Soumya

Hi Soumya,
I can able to integrate the glusterfs FSAL with NFS-Ganesha. Only think
i didn't get the libgfapi to link with FSAL compilation.
Requirement :
I'm going to use SDFS with NFS-Ganesha in my
project. For this i've taken Glustefs for my reference. After that i'm
getting confused with libgfapi. Actually how it is interacting with both
FSAL and Gluster filesystem. If i'm using libgfapi then Fuse layer is
required or not.
can i implement same like libgfapi for SDFS. If it is fine then how can
i start.
Thank you Very much for your response.

Hi Samuthira,
I have documented on how NFS-Ganesha is integrated with glusterfs in
the below blog post.

Kindly check the link and let me know if you have any more queries.
Also I am curious to know on what your usecase could be. Can you
please specify?

Hi Soumya,
Thank you very much for your reply. I need one more help from
your side,
i've downloaded the Glusterfs source code and just trying to
understand
the link between NFS-ganesha to glusterfs via FSAL. I've the
following
doubts,
1. Is libgfapi used for the interface between NFS ganesha
(Gluster FSAL)
to gluster filesystem?
2. I think we are not using the libfuse interafce. Is it right?
(FUSE
based architecture via kernel space fuse library)
3. How the internal linking is happening between FSAL to Gluster
filesystem?
Can you please guide me.
Thank you.

First verify if libgfapi.so* files are generated in

"/usr/local/lib".
If present, now verify if there are links created
to those
files in
"/usr/local/lib64" and "/usr/lib64". If not,
please create
the links
in those directories.
Eg:
[root@kvm2 glusterfs]# ls -ltr
/usr/local/lib64/libgfapi*
lrwxrwxrwx 1 root root 26 Aug 13 18:36
/usr/local/lib64/libgfapi.so

lrwxrwxrwx 1 root root 28 Aug 13 18:36
/usr/local/lib64/libgfapi.so.7 ->
/usr/local/lib/libgfapi.so.7
lrwxrwxrwx 1 root root 32 Aug 13 18:36
/usr/local/lib64/libgfapi.so.______7.0.0 ->
/usr/local/lib/libgfapi.so.7.______0.0
[root@kvm2 glusterfs]#
Now try to bringup the ganesha.

Only after setting up GlusterFS, you can
compile
nfs-ganesha with
GlusterFS by following the steps given in
the link
which
Anand has
forwarded.
cmake -DUSE_FSAL_GLUSTER=ON
-DCURSES_LIBRARY=/usr/lib64
-DCURSES_INCLUDE_PATH=/usr/________include/ncurses
