Rebooting the system is indeed the easy solution here. I could do it because it was my test setup. 1. Have you added any resources to this cluster? 2. Have you configured any services to this cluster? 3. Have you tried using a fence device. i.e., fence_manual? 4. Is there at times a heavy load on your network? 5. Have you opened all the ports on your firewall?
