As part of the gluster-colonizer tool, the zeroconf utilities require avahi. The avahi-0.6.31-17.el7.x86_64 package is currently available via the rhel-7-server-rpms channel. This should likely be set as an RPM dependency for the gluster-zeroconf-avahi package.
Fixed in version :: gluster-zeroconf-0.1.0-3.el7rhgs
verified that without avahi colonizer can't be installed. attached is the test screenshot, hence moving to verified
