Hi all, we were testing kafka disaster/recover in our Sites. Anyway do avoid the scenario in this post ? https://blog.softwaremill.com/help-kafka-ate-my-data-ae2e5d3e6576
But, the Unclean Leader exception is not an option in our case. FYI.. We needed to deactivated our systemctl for kafka brokers to avoid a service startup with a corrupted leader disk. Best Regards!
