(Resending to properly start new thread.)
Hi, 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? Thanks, Tom
