GFS2 two node cluster

bergest2 · June 28, 2016, 11:35pm

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,
J
