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