+Start Recovery Policy
+Start recovery policy comes in effect if a service failed to start on a node
+once ore more times. It can be used to configure how often a restart
+should be triggered on the same node and how often a service should be
+relocated so that it will tried to be started on another node.
+The aim of this policy is circumventing temporary unavailability of shared
+resources on a specific node. For example, if a shared storage isn't available
+on a quorate node anymore, e.g. network problems, but still on other nodes,
+the relocate policy allows then that the service gets started nonetheless.
+There are two service start recover policy settings which can be configured
specific for each resource.
