I am having similar scenario and we are having one Primary Master and One Back Up Master. Load switching is happen using Big IP load balancer. When Primary master goes down Back Up Master will become active Primary master.
We have added a heath check API in solr and when Primary master is back to normal it will check last delta/full import completion time with server startup time and heath API will only return Active Status if delta/full import completion time is greater than server startup time. Hope this make sense.
