[ClusterLabs] Stop action called after reboot and on all nodes

[Thomas Singleton]

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 ?


Thank you for your input
