I have ES nodes in ec2 with both with local ephemeral SSD disks and large  
EBS disks  
New indexes are created on daily basis.  
I want current day index to be created and on SSD disks  
with number\_of\_replicas = 1  
Once the day ends i want to move the index to EBS disks and change  
the number\_of\_replicas to 0

I could not find a feature to choose specific data dir for index shards at  
[http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/indices-update-settings.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/indices-update-settings.html)  
I know i can move index shards to different nodes (and control number of  
shards per node  
) with index.routing.allocation.\*, so I was wondering i can also control in  
which data dir within same node index shard will be created and realocated?

tnx
