You have a service locally installed on multiple hosts but only one service instance can run at any given time on that group of hosts. The network mounted pid file is what the local services use to determine whether or not an instance is already running. Simply put, the non-existence of a network pid file indicates that no instance is running and vice versa? Moreover, the service is enabled on all hosts and should really be running on only one host? Can you have the file validation logic in the start method and the first running instance will create the pid file which prevents the other instances(on other hosts) to run? Perhaps, the other instance can put themselves in temporary disable state.
Am I understanding your problem correctly? -tony
