Gentlmen,

I am trying figured out how to set my ES to share the docs between two partition.

For example:  
First Partition is mounted in "/data1"  
Second Partition is mounted in "/data2"

My elasticsearch.yml has:

> path:  
> data:  
> - /data1  
> - /data2

But, for any reason, only the First Partition (/data1) is being populated.

Does anyone know which other configuration i have to do in elasticsearch.yml to share the docs between these partition ?

Thanks,  
CLaudio Ract

It depends on how many shards you have. Elasticsearch will allocate a shard per disk. So depending on how shards and nodes you have, a few disks may still not be used until you have enough shards.

Hi Thiago,

Per day, I have this volumn:

> -bash-3.00# curl -XGET 'localhost:9200/\_cat/indices?v&pretty'  
> health status index uuid pri rep docs.count docs.deleted store.size pri.store.size  
> yellow open dcr\_openet DPIiTJDKTNK5J\_cLbHar6w 5 1 274500000 0 51.7gb 51.7gb

I have only 416 GB available in this partition (data1)

So, as I have defined two partition in elasticsearch.yml file, ES will allocate automatically the /data2 partition if necessary ?

I dont need set any other configuration in my elasticsearch.yml to make this balance ?
