You can configure this with pingd. The documentation is very confuse but
it's possible.
I make this with:
ha.cf:
ping_group ping_nodes 192.168.X.X 192.168.X.X # These are the ping nodes
of the documentation
cib.xml:
<clone id="pingd">
<instance_attributes id="pingd">
<attributes>
<nvpair id="pingd-clone_node_max" name="clone_node_max"
value="1"/>
</attributes>
</instance_attributes>
<primitive id="pingd-child" provider="heartbeat" class="ocf"
type="pingd">
<operations>
<op id="pingd-child-monitor" name="monitor" interval="20s"
timeout="40s" prereq="nothing"/>
<op id="pingd-child-start" name="start" prereq="nothing"/>
</operations>
<instance_attributes id="pingd_inst_attr">
<attributes>
<nvpair id="pingd-dampen" name="dampen" value="5s"/>
<nvpair id="pingd-multiplier" name="multiplier" value="100"/>
</attributes>
</instance_attributes>
</primitive>
</clone>
An then the rules in the same file:
<rsc_location id="my_resource:connected" rsc="RESOURCE_GROUP"> ##
Resource GROUP is the group of resources to move when a network failure
happens.
<rule id="my_resource:connected:rule" score="-INFINITY"
boolean_op="or">
<expression id="my_resource:connected:expr:undefined"
attribute="pingd" operation="not_defined"/>
<expression id="my_resource:connected:expr:zero"
attribute="pingd" operation="lte" value="0"/>
</rule>
</rsc_location>
I am trying to configure now a clone set of mysql servers and when pingd
or mysql resource tells an error, the VIP must be moved to another
cluster node!
Best Regards...

Hello,
Can anyone tell me where in Linux-ha is the Ethernet failure detected, which triggers the complete take-over procedure.
Can anyone suggest any documents related with the same.
Thanks in advance.
