[Pacemaker] Breaking dependency loop && stonith

Hi, ALL.

I want to clarify two more questions.
After stonith reboot - this node hangs with status "pending".
The logs found string .....

    info: rsc_merge_weights:    pgsql:1: Breaking dependency loop at msPostgresql
    info: rsc_merge_weights:    pgsql:2: Breaking dependency loop at msPostgresql

This means that breaking search the depends, because they are no more.
Or interrupted by an infinite loop for search the dependency?

And two.
Do I need to clone the stonith resource now (In PCMK 1.1.11)?
On the one hand, I see this resource on all nodes through command.
# cibadmin -Q|grep stonith
        <nvpair name="stonith-enabled" value="true" id="cib-bootstrap-options-stonith-enabled"/>
      <primitive id="st1" class="stonith" type="external/sshbykey">
          <lrm_resource id="st1" type="external/sshbykey" class="stonith">
          <lrm_resource id="st1" type="external/sshbykey" class="stonith">
          <lrm_resource id="st1" type="external/sshbykey" class="stonith">
(without pending node)

On the other hand, another command I see only one instance on a particular node.
# crm_verify -LVVVV

    info: LogActions:   Leave   pingCheck:3     (Stopped)
    info: LogActions:   Leave   st1     (Started dev-cluster2-node4)


However, if I do a "clone" - it turns out the same garbage.
