I am trying to figure out what is consuming disk space on my hot data node. When I run **GET \_cat/allocation** , the output shows that **disk.indices** is only consuming 80.4gb, whereas **disk.used** is 648.4gb. On my other hot data node the discrepancy between these two metrics is small. [Documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-allocation.html) says that **disk.indices** doesn't include unassigned shards or translogs, so how do I know what is taking up the 568gb of unaccounted-for space? ---

It could be due to unmerged segments, but that's a lot of space. What does a `df -h` show on that node? ---
