[ClusterLabs] Antw: [EXT] Stonith failing

[Gabriele Bulfon]

Thanks, I attach here the script.
It basically runs ssh on the other node with no password (must be preconfigured via authorization keys) with commands.
This was taken from a script by OpenIndiana (I think).
As it stated in the comments, we don't want to halt or boot via ssh, only reboot.
Maybe this is the problem, we should at least have it shutdown when asked for.
 
Actually if I stop corosync in node 2, I don't want it to shutdown the system but just let node 1 keep control of all resources.
Same if I just shutdown manually node 2, 
node 1 should keep control of all resources and release them back on reboot.
Instead, when I stopped corosync on node 2, log was showing the temptative to stonith node 2: why?
 
Thanks!
Gabriele

Gabriele,
 
"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.

Hi, now I have my two nodes (xstha1 and xstha2) with IPs configured by
Corosync.
To check how stonith would work, I turned off Corosync service on second
node.
First node try to attempt to stonith 2nd node and take care of its
resources, but this fails.
Stonith action is configured to run a custom script to run ssh commands,
I think you should explain what that script does exactly.
