<br>
I believe you are looking for stack convergence in Heat. It's not
fully implemented yet AFAIK.<br>
You can check it out here

Hope it will help you.<br>

<p class="MsoPlainText">I'm running a HA overcloud configuration
and as far as I'm aware, there is currently no mechanism in
place for restarting failed nodes in the cluster. Originally,
I had been wondering if we would use a corosync/pacemaker
cluster across the control plane with STONITH resources
configured for each node (a STONITH plugin for Ironic could be
written). This might be fine if a corosync/pacemaker stack is
already being used for HA of some components, but it seems
overkill otherwise. The undercloud heat could be in a good
position to restart the overcloud nodes -- is that the plan or
are there other options being considered?<o:p></o:p></p>
