Hello.  
Explain me please, how to work elastic data node if I set multiple path.data with different volumes.  
For explain, I set path.data: [/path/for/data1, /path/for/data2, /path/for/data3] where  
/path/for/data1 - 1Tb  
/path/for/data2 - 2Tb  
/path/for/data3 - 3Tb

How will the elastic fill these catalogs?  
I did not find this information in the documentation?

It is not the case of if path1 is full then it starts writing to path2, no.

Please see here: [Important Elasticsearch configuration | Elasticsearch Reference [6.1] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/6.1/important-settings.html#path-settings)

Please see my last post. Elasticsearch will not write just to one (data1 path) until it is full and then write to another, no. All paths will be utilised.

I understand that elastic use all data path. But if one of the path less than another data path, means a smaller path is filled faster than other paths. It is not clear how the elastic will work on?
