[ClusterLabs] Antw: [EXT] Stonith failing

"No route to host" is a somewhat generic error message when we can't find
anyone to fence the node. It doesn't mean there's necessarily a network
routing issue at fault; no need to focus on that error message.

I agree with Ulrich about needing to know what the script does. But based
on your initial message, it sounds like your custom fence agent returns 1
in response to "on" and "off" actions. Am I understanding correctly? If so,
why does it behave that way? Pacemaker is trying to run a poweroff action
based on the logs, so it needs your script to support an off action.
