Ok, so right now Dummy only takes one parameter called "state" (no
idea why I called it that).
Add a new one, but make it non-unique.
<parameter name="somename" unique="0">
<longdesc lang="en">
Random parameter that, when changed, causes a reload instead of a restart
</longdesc>
<shortdesc lang="en">Some parameter</shortdesc>
<content type="string" default="" />
</parameter>
And make sure the agent advertises the reload operation:
<action name="reload" timeout="90" />
Then when defining the resource, include an nvpair for "somename". eg
<primitive class="ocf" id="test" provider="heartbeat"
type="Dummy">
<instance_attributes id="test">
<attributes>
<nvpair id="test_someename"
name="someename" value="a"/>
</attributes>
</instance_attributes>
</primitive>
Then just change the value of "somename" and the resource will get reloaded.
