<p>Hi All,</p>
<p><br>
</p>
<p>I'm running Pacemaker 2.0.1 on a cluster containing two nodes; one master and one slave. I have a main master/slave resource (m_main_system), a group of resources that run in active-active mode (active_active - i.e. run on both nodes), and a group that runs
in active-disabled mode (snmp_active_disabled - resources only run on the current promoted master). The snmp_active_disabled group is configured to be co-located with the master of m_main_system, so only a failure of the master m_main_system resource can trigger
a failover. The constraints specify that m_main_system must be started before snmp_active_disabled.<br>
</p>
<p><br>
</p>
<p>The problem I'm having is that when a resource in the snmp_active_disabled group fails and gets into a constant cycle where Pacemaker tries to restart it, and I then kill m_main_system on the master, then Pacemaker still constantly tries to restart the failed
snmp_active_disabled resource and ignores the more important m_main_system process which should be triggering a failover. If I stabilise the snmp_active_disabled resource then Pacemaker finally acts on the m_main_system failure. I hope I've described this
well enough, but I've included a cut down form of my CIB config below if it helps!</p>
<p><br>
</p>
<p>Is this a bug or an error in my config? Perhaps the order in which the groups are defined in the CIB matters despite the constraints? Any help would be gratefully received.</p>
<p><br>
</p>
<p>Thanks,</p>
<p>Harvey</p>
