<p class="MsoNormal">Hope you are doing well.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a 4 node pacemaker cluster where I created clone dummy resources test-1, test-2 and test-3 below:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><b>$ sudo pcs resource create test-1 ocf:heartbeat:Dummy op monitor timeout="20" interval="10" clone<o:p></o:p></b></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Then I ordered them so test-2-clone starts after test-1-clone and test-3-clone starts after test-2-clone:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><b>$ sudo pcs constraint order test-1-clone then test-2-clone<o:p></o:p></b></p>

<p class="MsoNormal">Here are my clone sets(snippet of "pcs status" output pasted below):<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Then I restart test-1 on just node1_a:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><b>$ sudo pcs resource restart test-1 node1_a<o:p></o:p></b></p>

<p class="MsoNormal">This causes test-2 and test-3 clones to restart on all pacemaker nodes when my intention is for them to restart on just node1_a.<o:p></o:p></p>
<p class="MsoNormal">Below is the log tracing seen on the Designated Controller NODE1-B:<o:p></o:p></p>

<p class="MsoNormal">Above is a representation of the observed behavior using dummy resources.
<o:p></o:p></p>
<p class="MsoNormal">Is this the expected behavior of cloned resources?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My goal is to be able to restart test-2-clone and test-3-clone on just the node that experienced test-1 restart rather than all other nodes in the cluster.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please let us know if any additional information will help for you to be able to provide feedback.<o:p></o:p></p>
