Gluster Add node failure error: No route to host

This problem occurs with Glusterfs 3.4.7 and gluster3.6.4.

The server side executes the Add Peer command to report the following error:

Probe returned with unknown errno 107

The corresponding log error message is as follows:

[2015-08-25 02:47:06.818281] I [glusterd-handler.c:1031:__glusterd_handle_cli_probe] 0-glusterd:received CLI Probe req node61 24007

In fact, root cause is the authority problem, gluster error is more outrageous.

Solution:

Turn off firewall or open Gluster related port permissions.
