I’m trying to implement a HA solution which recovers very quickly when a node fails. It my configuration, when I reboot a node, I see in the logs that pacemaker realizes the node is down, and decides to move all resources to the surviving node. To do this, it initiates a ‘stop’ operation on each of the resources to perform the move. The ‘stop’ fails as expected after 20s (the default action timeout). However, in this case, with the node known to be down, I’d like to avoid this 20 second delay. The node is known to be down, so any operations sent to the node will fail. It would be nice if operations sent to a down node would immediately fail, thus reducing the time it takes the resource to be started on the surviving node. I do not want to reduce the timeout for the operation, because the timeout is sensible for when a resource moves due to a non-node-failure. Is there a way to accomplish this?
Thanks for your help.
