Is it impossible? We have 3 elasticsearch servers with similar config: ``` path: data: - /data/1/elasticsearch - /data/2/elasticsearch - /data/3/elasticsearch - /data/4/elasticsearch ``` df -h: ``` /dev/sda4 5,2T 239G 4,7T 5% /data/1 /dev/sdb4 5,2T 304G 4,7T 7% /data/2 /dev/sdc4 5,2T 238G 4,7T 5% /data/3 /dev/sdd4 5,2T 283G 4,7T 6% /data/4 ``` from filebeats -\> logstashes -\> elastic we receive many logs (around 30.000/sec). I disable replication (we don't afraid to lose logs). On day we have two index - filebeat-7d, filebeat2-7d, delete index older than 7 days. Shards per index I didn't change. In grafana I view that not all disks are using ![node1](https://us1.discourse-cdn.com/elastic/original/3X/9/a/9a33610200adf3580aeb6807cc3b124df7fa22bc.png) ![node2](https://us1.discourse-cdn.com/elastic/original/3X/0/e/0e7e3ddd2cc70f9c13dca984a655d94675bb538f.png) It will be cool, if I may be to force elasticsearch to use all path.data. it seems to me, that I must change default shards per index - increase or decrease? In google, I search and find, that for high perfomance I need decrease shards per index. But, logically: 3 servers \* 4 path.data = 12 6 shards per index? Could any one explain how right choose shards or another option for utilization all disks? ---

Elasticsearch balances shards across nodes, but not across data paths within each node. If you want this kind of balancing, I suggest you try running 12 nodes, each on a single data path. ---
