heartbeat - Heartbeat subsystem for High-Availability Linux
heartbeat is a basic heartbeat subsystem for Linux-HA. It will run scripts at initialisation, and when machines go up or down. This version
will also perform IP address takeover using gratuitous ARPs. It works correctly for a 2-node configuration, and is extensible to larger
It implements the following kinds of heartbeats:
o UDP/IP broadcast;
o UDP/IP multicast;
o UDP/IP unicast;
o Bidirectional Serial Rings ("raw" serial ports) -- this type is deprecated and should no longer be used;
o special "ping" heartbeats for routers, etc. -- this type has been superseded by functionality in pacemaker() and should no longer be
Comprehensive documentation on heartbeat is available in the Heartbeat User's Guide. If this documentation is not installed on your system,
it can be found at http://linux-ha.org/.
The following options are supported by heartbeat:
Increment debugging level. Higher levels are more verbose.
Reload heartbeat. This option is functionally identical to sending a running heartbeat process a HUP signal. If the configuration has
not changed, then this option is essentially a no-op. If ha.cf(5) or authkeys(5) has changed, then heartbeat will re-read these files
and update its configuration.
This option may not be used together with -R.
Kill (stop) heartbeat.
Report heartbeat status.
Heartbeat restart exec flag (internal use only). May not be used with -r.
Heartbeat current resource state for restart (internal use only). Only valid with -R.
Print out heartbeat version.
Note that most of these options are used for supporting the heartbeat init script, which provides the conventional start, stop, status and
restart options (among others). It is recommended to use this rather than invoking the heartbeat command directly.
