<b>Subject:</b> [Pacemaker] PingD Failure-Timeout<o:p></o:p></span></p>
</div>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a way to time-out the failure of PingD? <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In my configuration, I cannot run PingD all the time on every node. Only one node (the master) has public Internet access. I use PingD to cause the master to fail-over to one of the slaves. When a slave becomes master, it then gains public
Internet connectivity. When it is a slave, the entire interface is down, so not even the gateway is reachable. So, I set up a PingD resource that is co-located with the master resource in the Master state. I also set up constraints that assign a -1000 score
to a node for each resource if that node loses connectivity to the gateway. The result is that if I firewall off ICMP on the master, it correctly fails over to a slave. Then, it runs a stop on the master, as expected since it has a -1000 score. The result
is that my master resource runs as Master on the node that was the slave, and is Stopped on the node that was the master. However, it is still stuck with a -1000 score, and will never restart on the node that was the master until PingD thinks it has connectivity
back. But that won’t happen because PingD no longer runs on that node since the interface is down on it and it won’t see anything if it did.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I set a failure-timeout on the PingD resource, but it does not seem to do anything. Running ‘crm_verify –VVVVV –L 2>&1 | less’ shows that the -1000 score stays there, even well past the failure-timeout.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anybody have any suggestions how I can automatically clear that -1000 score after a certain (small) interval of time?<o:p></o:p></p>
