<p class="MsoNormal">As you can see, pcs status indicates that “main-multi-state-resource" stopped where corosync was killed on “pace_node_a” and started on “pace_node_b”. Although, this indication is right, the underlying resource managed by “main-multi-state-resource”
never stopped on “pace_node_a". Also, there were no logs from crmd and other components stating it even attempted to stop on “pace_node_a”. Interestingly, crmd logs indicated that the colocated resource – “colocated-resource" was being stopped and there is
evidence that the resource managed by “colocated-resource” actually stopped.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is this a known issue? <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please let us know if any additional information is needed.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your help!<o:p></o:p></p>
