2.4. Quickly Deleting Part of the Configuration

Identify the object you wish to delete. eg.

  # cibadmin -Q | grep stonith

   <nvpair id="cib-bootstrap-options-stonith-action" name="stonith-action" value="reboot"/>
   <nvpair id="cib-bootstrap-options-stonith-enabled" name="stonith-enabled" value="1"/>
  <primitive id="child_DoFencing" class="stonith" type="external/vmware">
   <lrm_resource id="child_DoFencing:0" type="external/vmware" class="stonith">
   <lrm_resource id="child_DoFencing:0" type="external/vmware" class="stonith">
   <lrm_resource id="child_DoFencing:1" type="external/vmware" class="stonith">
   <lrm_resource id="child_DoFencing:0" type="external/vmware" class="stonith">
   <lrm_resource id="child_DoFencing:2" type="external/vmware" class="stonith">
   <lrm_resource id="child_DoFencing:0" type="external/vmware" class="stonith">
   <lrm_resource id="child_DoFencing:3" type="external/vmware" class="stonith">

Next identify the resource's tag name and id (in this case we'll chose primitive and child_DoFencing). Then simply execute:

cibadmin --delete --crm_xml ‘<primitive id="child_DoFencing"/>'
