Bug 763494 (GLUSTER-1762)

I tried to add wrong brick - (a brick where glusted was not started) and cancelled it.

[root@compute-241-02 ~]# gluster peer probe  172.24.21.134
^c

then added correct brick -
[root@compute-241-02 ~]# # gluster peer probe  172.24.21.132
Probe successful

and checked its status
[root@compute-241-02 ~]# gluster peer status
Number of Peers: 2
hostname:172.24.21.134, uuid:00000000-0000-0000-0000-000000000000, state:0 (disconnected)
hostname:172.24.21.132, uuid:1f4adc52-aa20-4232-9c1b-b1a166e8ec17, state:3 (connected)

after removing peer using detach - and status check - found a glusterd core  file

[root@compute-241-02 ~]# gluster peer detach 172.24.21.134
Detach successful
[root@compute-241-02 ~]# gluster peer status
Connection failed. Please check if gluster daemon is operational.
