usage: $0 (start|stop|status|reload|monitor|validate-all|meta-data)
$0 manages the File System as an HA resource
The 'start'...... operation starts the service.
The 'stop'....... operation stops the service.
The 'reload'..... operation stops and then starts the service.
The 'status'..... operation checks the status of the service.
The 'monitor'.... operation indicates the in-service status of the service.
The 'validate-all' operation reports whether the parameters are valid.
The 'meta-data'... operation reports the meta-data information.
