All OCF RAs are available in
/usr/lib/ocf/resource.d/. The scripts that are
delivered with the Heartbeat package are found in this directory in
the subdirectory heartbeat. To avoid name
clashes, create a different subdirectory when creating new
resource agents. For example, if you have a resource group
kitchen with the resource
coffee_machine, add this resource to
the directory
/usr/lib/ocf/resource.d/kitchen/. To access
this RA, the configuration would look like:
<primitive id="coffee_1" class="ocf" type="coffee_machine" provider="kitchen"/>
When implementing your own OCF RA, provide several actions for this agent. More details about writing OCF resource agents can be found at http://www.linux-ha.org/OCFResourceAgent. Find special information about several concepts of Heartbeat 2 at http://linux-ha.org/v2/Concepts.
