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
It implements the following kinds of heartbeats:
* Bidirectional Serial Rings ("raw" serial ports)
* UDP/IP broadcast (ethernet, etc.)
* UDP/IP multicast (ethernet, etc.)
* special "ping" heartbeats for routers, etc.
Comprehensive documentation on the configuration and running of
heartbeat can is supplied in HTML format with the distribution of the
code. If this documentation is not installed on your system it can be
found, with the latest distribution of heartbeat on http://www.linux-
-d Increment debugging level. Higher levels are more verbose.
-r Reloads heartbeat. It just sends it a SIGHUP. If nothing has
changed nothing will happen. If ha.cf or authkeys has changed
it will start heartbeat or reread authkeys. May not be used with
-k Kill (stop) heartbeat.
-s Report heartbeat status.
-R Heartbeat restart exec flag (internal use only). May not be
used with -r.
-C Heartbeat current resource state for restart (internal use
only). Only valid with -R.
-V 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.
