> KIP-113 introduced support for moving replicas between log directories. As part of it, support was added to kafka-reassign-partitions.sh so that users can move replicas between log directories. Specifically, when you call "kafka-reassign-partitions.sh --topics-to-move-json-file topics-to-move.json", you can specify a "log_dirs" key in the topics-to-move.json file, and kafka-reassign-partitions.sh will then move those replicas to those directories.
>  
> However, when working on that KIP, we didn't update the docs on kafka.apache.org to describe how to use the new functionality. We should add documentation on that.
>  
> I haven't used it before, but whoever works on this Jira can probably figure it out by experimentation with kafka-reassign-partitions.sh, or by reading KIP-113 page or the associated JIRAs.
