Bug 1004699

Description of problem:
glusterd: If RHSS is already part of another cluster and User tries to add it using command 'gluster peer probe <hostname/ip>' ; It is failing  with error 'peer probe: failed:' but not giving reason for failure


Version-Release number of selected component (if applicable):
3.4.0.30rhs-2.el6rhs.x86_64

How reproducible:
always

Steps to Reproduce:
1. had a cluster of 2 RHSS
[root@DHT2 ~]# gluster peer status
Number of Peers: 1

Hostname: 10.70.37.195
Uuid: 0d0f02d7-1dd1-4252-bff9-3c28b113fba0
State: Peer in Cluster (Connected)


2. try to add one of this RHSS node from 3rd RHSS as below

[root@DHT3 ~]# gluster peer probe 10.70.37.66
peer probe: failed: 
[root@DHT3 ~]# echo $?
1



Actual results:
It is not giving any reason for failure

Expected results:
It should give reason for failure. It should say that host is already part of another cluster

-> In Anshi It was giving reason for failures as below:-

[root@localhost ~]# gluster peer probe 10.70.42.186
10.70.42.186 is already part of another cluster

[root@localhost ~]# glusterfs -V
