Glusterfs is a scalable network filesystem with capabilities of scaling to several petabytes and handling thousands of clients. In the above examples, port 4789 is used for User Datagram Protocol (UDP). dnsmasq is automatically configured on all masters and nodes. As of Red Hat Enterprise Linux 7.4, you have the option to configure your default zone, which ensure that firewalld is configured correctly.
