These are the basic configurations:
* The file name to write debugging messages (optional): Debug messages generated by the heartbeat will be recorded in this file.
* The file name to write other messages (optional): The file where all the log messages and warnings will be recorded.
* Facility to be used with the syslog/logger (optional):
* Watchdog device (optional): If this node sends no sign to the watchdog device for a minute, it will be restarted (reboot).
* How many seconds between "heartbeats" (optional): This option configures the keepalive item, which defines the amount of time in seconds on which a heartbeat will be sent to the cluster.
* Time (s) to declare a node dead (optional): Configures the deadtime, the time in seconds without receiving messages from a determined node after which it will be declared dead.
* Number of hops, for ring topologies (optional): (hopfudge) The maximum number of hops less the number of nodes in the configuration file.
* Transmission Rate (baud rate) for serial ports (optional): Defines the transmition rate of the serial ports used.
* UDP Port (optional): The UDP Port used for communication between the nodes.
* Nice_failback Controls the system behaviour in case of a failback, return after fail, or primary server initialization. If this option is enabled, when the primary server - the one which has resources associated to its name in the configuration files - is in the initialization process, it checks out if the cluster is already active. In the case of an affirmative answer and some node is already taking care of the resources which correspond to this server, this one acts like the secondary. This option is an alternative to the standard heartbeat behaviour, on which the primary server *always* takes its resources back on restart.
