One of the common requests we get is to be able to easily move all Kafka logs between two disks on the JBOD storage array. This is useful for example when:

• Your current disk is too big and you want to use smaller one
• You watch to use different Storage Class with different parameters or different storage type

Currently, this needs ot be done using the Kafka CLI tools which is not really user-friendly. It would be nice to have an option to do it through Cruise Control and have CC handle moving the logs.
