EXTERNAL module for Linux-HA STONITH
-This stonith plug in runs an external command written in your favorite
+This stonith plugin runs an external command written in your favorite
language to shutdown the given host. The external command should return
a zero exit status after a successful shutdown, or non-zero exit status
for a shutdown failure. Failures notifications will be sent to syslog.
-To configure the plug in, add this line to /etc/ha.d/rpc.cfg
+To create your own external plugin, write a script that supports the
+following actions:
-stonith external
+ reset
+ on (optional)
+ off (optional)
+ gethosts
+ status
+ getconfignames
+ getinfo-devid
+ getinfo-devname
+ getinfo-devdescr
+ getinfo-devurl
+ getinfo-xml
-/etc/ha.d/rpc.cfg should contain lines like the following:
+and place it in the /usr/lib/stonith/plugins/external directory - the
+script must be a regular executable file that is NOT writable by group
+or others in order to be recognized as an external plugin. If the
+action requires information to be returned, such as the list of hosts
+or config names or any of the getinfo-* calls, simply write the
+information to stdout. When complete, return zero to indicate the
+action succeeded or non-zero to indicate the action failed. You can
+use the ssh (sh) and riloe (pyhton) scripts already in that directory
+as working examples.
-hostname.domain.org /path/to/command [argument]...
-otherhost.domain.org /path/to/command [argument]...
+To make sure that your external plugin is recognized, run "stonith -L"
+and look for its name in the output, something along the lines of:
-Where /path/to/command gives the location of your shutdown script.
+ external/yourplugin
+
+To configure the plugin on an R1 (legacy) cluster, add a line similar
+to the following to /etc/ha.d/ha.cf:
+
+ stonith external/yourplugin /etc/ha.d/yourplugin.cfg
+
+where /etc/ha.d/yourplugin.cfg contains a single line with all of your
+plugin's required parameters and any optional ones as well:
+
+ parm1-value parm2-value ...
+
+Another way to configure the plugin on a legacy cluster is to add a line
+similiar to the following to /etc/ha.d/ha.cf instead:
+
+ stonith_host * external/yourplugin parm1-value parm2-value ...
+
+where all of your plugin's parameters are placed at the end of the line.
+
+Please note that all parameters come in to the plugin in name/value
+(environment variable) form, but in R1 configurations, they appear as a
+list of parameters. They are ordered in the config file or on the
+stonith_host line according to the ordering specified in the output of
+the getconfignames operation.
+
+To configure the plugin on an R2 cluster, place lines similar to the
+following into the <resources> section of your CIB, which is contained
+in /var/lib/heartbeat/crm/cib.xml:
+
+ <clone id="DoFencing">
+ <instance_attributes>
+ <attributes>
+ <nvpair name="clone_max" value="2"/>
+ <nvpair name="clone_node_max" value="1"/>
+ </attributes>
+ </instance_attributes>
+ <primitive id="child_DoFencing" class="stonith"
type="external/yourplugin" provider="heartbeat">
+ <operations>
+ <op name="monitor" interval="5s" timeout="20s"
prereq="nothing"/>
+ <op name="start" timeout="20s" prereq="nothing"/>
+ </operations>
+ <instance_attributes>
+ <attributes>
+ <nvpair name="parm1-name" value="parm1-value"/>
+ <nvpair name="parm2-name" value="parm2-value"/>
+ <!-- ... -->
+ </attributes>
+ </instance_attributes>
+ </primitive>
+ </clone>
+
+Whatever <nvpair> parameters specified in the <attributes> section of
+the CIB are passed to the script as environment variables. For the
+example above, the parameters are passed as parm1-name=parm1-value,
+parm2-name=parm2-value and so on.
