<p>Hi Andreas, <br>
</p>
<p>By checking the code IMO currently this is limitation with in
FSAL_GLUSTER. It tries to <br>
</p>
<p>establish connection with glusterfs servers only using "tcp". It
is easy to fix as well.</p>
<p> You can raise a bug in <a
href="https://bugzilla.redhat.com/enter_bug.cgi?product=nfs-ganesha">https://bugzilla.redhat.com/enter_bug.cgi?product=nfs-ganesha</a>
<br>
</p>
<p>under FSAL_GLUSTER. I don't have any hardware to test the fix. I
can either help you in</p>
<p>writing up fix for the issue or provide a test rpms with the fix
.</p>
<p>Also thanks for trying out nfs-ganesha with rdma and finding
about this issue.</p>
<p>For the time being , if possible you can try with tcp,rdma volume
to solve the problem.</p>
<p>Regards,</p>
<p>Jiffin<br>
