Interesting - we've seen far better performance with
Ganesha v4.1 vs. gnfs. <br>

<p>Amazing! But it's not fair, the results is old glusterfs vs new
glusterfs but not nfs-ganesha vs gnfs. <br>
</p>
<p>Anyway i'll test the last nfs-ganesha versus gnfs, and get back
later.<br>

<p>Gnfs is stable enough, we have about ~1000

about ~2000 nfs clients, all works fine till
the last two years expect some memleak

<div dir="ltr">Hi All,
<div><br>
</div>
<div>As per the discussion on <a
href="https://review.gluster.org/23645"
rel="noreferrer" target="_blank"
moz-do-not-send="true">https://review.gluster.org/23645</a>,
recently we changed the status of
gNFS (gluster's native NFSv3
support) feature to 'Depricated /
Orphan' state. (ref: <a
href="https://github.com/gluster/glusterfs/blob/master/MAINTAINERS#L185..L189"
rel="noreferrer" target="_blank"
moz-do-not-send="true">https://github.com/gluster/glusterfs/blob/master/MAINTAINERS#L185..L189</a>).
With this email, I am proposing to
change the status again to 'Odd
Fixes' (ref: <a
href="https://github.com/gluster/glusterfs/blob/master/MAINTAINERS#L22"
rel="noreferrer" target="_blank"
moz-do-not-send="true">https://github.com/gluster/glusterfs/blob/master/MAINTAINERS#L22</a>) </div>
<div><br>
</div>
<div>TL;DR;</div>
<div><br>
</div>
<div>
<div>I understand the current
maintainers are not able to
focus on maintaining it as the
focus of the project, as earlier
described, is keeping
NFS-Ganesha based integration
with glusterfs. But, I am
volunteering along with Xie
Changlong (currently working at
Chinamobile), to keep the
feature running as it used to in
previous versions. Hence the
status of 'Odd Fixes'. </div>
<div><br>
</div>
<div>Before sending the patch to
make these changes, I am
proposing it here now, as gNFS
is not even shipped with latest
glusterfs-7.0 releases. I have
heard from some users that it
was working great for them with
earlier releases, as all they
wanted was NFS v3 support, and
not much of features from gNFS.
Also note that, even though the
packages are not built, none of
the regression tests using gNFS
are stopped with latest master,
so it is working same from at
least last 2 years. </div>
</div>
<div><br>
</div>
<div>I request the package
maintainers to please add '--with
gnfs' (or --enable-gnfs) back to
their release script through this
email, so those users wanting to
use gNFS happily can continue to
use it. Also points to
users/admins is that, the status
is 'Odd Fixes', so don't expect
any 'enhancements' on the features
provided by gNFS.</div>
<div><br>
</div>
<div>Happy to hear feedback, if any.</div>
<div><br>
</div>
<div>Regards,</div>
<div>Amar</div>
