Hi, First of all, the purpose of having 3 ZK in ensemble is to minimise the chances of loosing quorum. With 3 ZK, you can loose one and still have operable ZK ensemble. You should monitor it and alert if you loose one ZK and react to alert before you loose the second one. If you are wondering how to monitor it, you can check out Sematext’s performance monitor: https://sematext.com/spm/ <https://sematext.com/spm/> If you loose the second ZK, then you either ignored the alert or you are really unlucky person or you have something terribly wrong in your setup.
Anyway, if that happens, there is nothing in Solr that keeps track what is indexed and what is not. You need to track that on your client side. It can be loosely tracking by some timestamp or strictly tracked by acknowledging every indexed document. In some cases it might be the simplest if you do full reindexing.
