Vadym,

Thanks for the feedback.  I do test this scenario and it works for me:

[root at cast flatiron]# service corosync start
Starting Corosync Cluster Engine (corosync):               [  OK  ]
[root at cast flatiron]# service corosync restart
Signaling Corosync Cluster Engine (corosync) to terminate: [  OK  ]
Waiting for corosync services to unload:.                  [  OK  ]
Starting Corosync Cluster Engine (corosync):               [  OK  ]
[root at cast flatiron]# service corosync stop
Signaling Corosync Cluster Engine (corosync) to terminate: [  OK  ]
Waiting for corosync services to unload:.                  [  OK  ]
[root at cast flatiron]# service corosync start
Starting Corosync Cluster Engine (corosync):               [  OK  ]
[root at cast flatiron]# /etc/init.d/corosync restart
Signaling Corosync Cluster Engine (corosync) to terminate: [  OK  ]
Waiting for corosync services to unload:.                  [  OK  ]
Starting Corosync Cluster Engine (corosync):               [  OK  ]


One thing that would stop corosync from shutting down is if it couldn't 
enter operational state.  This often happens because of a firewall 
enabled on the ports corosync uses to communicate.

The system logs would be helpful (with debug: on).
