Mike, One issue in your CIB (though may not be the cause of this) is the order statement with promote: order ordDRBDDLM inf: msDRBD:promote cloneDLM If you explicitly define the action to take (promote) then that action is taken on all resources in that statement unless explicitly defined otherwise. So it should be: order ordDRBDDLM inf: msDRBD:promote cloneDLM:start Have you tried just rebooting the offending node? I know that's not the greatest answer but it's not serving anything right now anyway. Also how about attaching the logs when the disconnect happened from both nodes?
