If all replicas of a partition are offline, your partition is unavailable. As such, there isn't a way for Kafka to copy data consistently from brokers that are offline. If you are worried that an entire rack or data center might go offline, you will need to ensure that your replicas are not on the same rack or you have a multi dc strategy using cross dc replicas or mirror makers. We have a JIRA open to do rack aware replica assignment automatically, but the work is not complete yet.
