Kafka is not concerned about your disks and it does not do anything lower than writing files to a folder. Meaning, the best way to add more capacity to your servers is to stop the service add the drives create a new volume and data folder copy over the data from previous location and mount the new volume to the right place (/data for me). After that you can start to service again.
This also can be done in a seamless fashion without service interruption. I.
