Gluster users - Mar 2015 - Upgrade from 3.5 to 3.6: issue with socket

Actually I could solve my issue with the mounting of the volume by re-installing
Gluster 3.6 from scratch. Before that I tried to update the volfile as I read in
a bug but that did not work. So the only last problem which remains is this
warning error with the socket as reported.

As I did indeed disable NFS on all my volumes (currently only one) I suppose
this is why as you suggest Joe. But this is really annoying having a log entry
every 3 seconds in gluster's log file. How can I fix or avoid that? I would
say this might be a bug?

This is a bug. Could you raise a bug and provide the id in this thread?
Meanwhile, I will send out a patch for review on master and release-3.6 branch.
Thanks for reporting this issue.

Thanks Joe Julian for giving the crucial piece of lead which helped me identify
the issue.
