My current setup is with 10 nodes with ample space on spinning disks, and 20 nodes with smaller SSD disks. I would like my workflow to be that all data is initially indexed on the SSD nodes, after 10 days is reallocated to the spinning disks, after a further 10 days the index is closed, and after a further 70 days the indexes are deleted. The curator is great for moving them to the spinning disks, but what I am not sure about is how to define that initially all shards (primary and replica) of an index should be created on the ssd nodes. The spinning disk nodes are tagged: node.disk\_type: spinning The ssd nodes are tagged node.disk\_type: ssd To transfer after 10 days to spinning: /usr/local/bin/curator --host es101 allocation --older-than 9 --rule disk\_type=spinning But how do I define that the default location for all new shards should be on disk\_type:ssd ? I have the example here [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-cluster.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-cluster.html) which I think could be modified like this: curl -XPUT localhost:9200/\_cluster/settings -d '{ "persistent" : { "cluster.routing.allocation.require.disk\_type" : "ssd" } }' But for one this setting does not exist, and I'm not sure if this will stop the shards being reallocated to spinning later on... Any ideas how to implement my desired workflow? Thank you! -Robin- -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Check what curator is doing with your index. Its probably fiddling with index.routing.allocation.include and index.routing.allocation.exclude. When you create the new index just set it pick up the ssd tag. You'll have to make sure that curator knows how to strip that tag when the time comes to move it to the spinning disks.
