Hi,

I’m trying to configure a sles 12 two node GFS cluster, everything works fine and the GFS2 volumes getting mounted on both nodes. But if I try to fence one of the nodes the other node is fencing also after a wile. I see the following log enteis after i executing a stonith\_admin -f suse2 in the logs where my first node suse1 is self fencing / rebooting:

Hi,

anything you see in the logs of suse1 right before it is rebooted itself? Anything in the logs of suse2 indicating a reason for reboot of suse1?

Regards,

Please check if you encountered this issue:  
[https://github.com/ClusterLabs/pacemaker/pull/839](https://github.com/ClusterLabs/pacemaker/pull/839)

Upgrade your dlm and pacemaker packages if so, or just revert that patch for controld RA from that redhat guy.
