glusterfsd fails if the glusterd is bind to specific-IP address. This patch helps glusterfsd to get the volfile using Unix domain socket. glusterfs -s <unix socket path> --volfile-server-transport unix --volfile-id <volume-name> <mount-point> The patch checks if the volfile-server-transport is of type "unix", If It is then uses rpc_transport_unix_options_build to get the volfile.
