I wonder why this seems problematic to you. This is perfectly normal Elasticsearch behavior. It does not balance by disk space, rather it uses the [low and high watermarks](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-cluster.html#disk-based-shard-allocation) to ensure that no node gets to a full disk.

As long as your workload is served well, this is no problem. Perhaps there is an underlying symptom you are chasing?
