Hi, I tested to set the value of 'deadping' to 3 with a 'dampen' value of 1
ha.cf:
<snip>
initdead 30
deadtime 2
keepalive 800ms
warntime 1800ms
deadping 3
</snip>
xml snippet for resource pingd:
<clone id="clone-pingd">
<meta_attributes id="clone-pingd-meta-attrs">
<nvpair id="clone-pingd-meta-attr-clone-max" name="clone_max" value="2"/>
<nvpair id="clone-pingd-meta-attr-clone-node-max" name="clone_node_max"
value="1"/>
</meta_attributes>
<primitive id="pingd" class="ocf" type="pingd" provider="heartbeat">
<operations>
<op id="op-pingd" name="monitor" interval="1s" timeout="1s"/>
</operations>
<instance_attributes id="pingd-inst-attrs">
<nvpair id="pingd-inst-attr-multiplier" name="multiplier" value="200"/>
<nvpair id="pingd-inst-attr-dampen" name="dampen" value="1s"/>
<nvpair id="pingd-inst-attr-host-list" name="host_list"
value="default-gateway switch1 switch2"/>
</instance_attributes>
</primitive>
</clone>
But the cluster still behaves as before. After the master node lost its
connection to one ping node, the failover occurs at least 70 seconds later.
In addition it would be great to reduce the ping testing interval. it still
sticks at 10 seconds. As you can see I tried to set it to one seconds.
When i look into meta-data of ocf-RA pingd i can found this entries:
<actions>
<action name="start" timeout="90" />
<action name="stop" timeout="100" />
<action name="monitor" depth="0" timeout="20" interval="10" start-delay="1m" />
<action name="meta-data" timeout="5" />
<action name="validate-all" timeout="30" />
</actions>
I guess the op attribute 'interval' means something like pingd test interval,
right?
As far as I can remember in heartbeat version 2.1.4 the default test interval
for pingd was 1 second.
Greetings,
Joerg
