[Gluster-users] remote operation failed [Permission denied] every 10 minutes after upgrading from 5.10 to 7.0

Thanks Amar,

Checking the brick logs, I'm seeing these and numerous other files with
Permission denied. The question is why is the permission being denied?
Gluster runs as root and the files are owned by wwwrun:www, which it should
have full access to.

Is there any more documentation on what enabling or disabling this feature
accomplishes, why it was added to 7.1 by default (and 7.0 as far as I can
tell), and what side effects it may have? Basically, I'd like to understand
the problem better instead of simply turning the flag off and fix the
underlying issue (or help fix a bug if it's a bug in gluster).

Btw, cluster.op-version is 70000, which is the latest. I always rev it up
after upgrading the cluster.
