Hi, Does anybody know how to solving this "fence loop" ? > master_wins="1" is not working properly, qdisk also. > Logs shared are not sufficient to identify the cause of fence loop. I would suggest you to 1. Disable cman - chkconfig cman off ( and rgmanager also if you wish ) - on both the nodes . 2. Reboot both the nodes 3. Once the machine is up, open two terminals 4. Start cman manually on both the nodes 5. share the behaviour and logs generated. Cheers,
