Dear all With the following cluster setup : 2 nodes and one spare, two ressources, full config at the end of message Test resource is a simple binary with a sleep loop and logging in the heartbeat script
When one node is rebooted, two actions occur that we are trying to understand : - When first node is taken offline by a reboot command the resource is started on the spare as expected, when the node is back online the resource on the spare is stopped, again as expected BUT on the second node, the resource also receives a stop/start command - When first node is taken offline by a reboot, when node is back online, resource is stopped on spare BUT on the first node the action called in the heartbeat script is the stop action and not the start action as one would expect (thus preventing the resource from coming back online) How can we explain these two actions ?
