Hi, I am using elastic search 6.3. I have 4 nodes of ES Cluster of nodesize (1Tb). 1 node disk space left is 10 GB and rest of 3 nodes have disk size of more than 70GB. I want to normalize the disk size. I want my first node shouldn't be utilize less or if i can stop that node to process. I have already implemented index deletion after 45 days. ---

The [disk-based shard allocator](https://www.elastic.co/guide/en/elasticsearch/reference/6.7/disk-allocator.html) balances the free disk space by moving shards away from a node that is too full (i.e. has exceeded `cluster.routing.allocation.disk.watermark.high`). ---
