Hi I have an index in ES , with 5 shards , 0 replicas and , indexing some data with Parent child relationship. The size of the index is 1.1 GB. I am setting child document's id, parent , and routing value , as the parent's ID , and parent's routing value also the same (to enable , that both the documents go to the same shard) . When i go and delete the child mapping , data is expected to be deleted, which is reflected by the REST API (\_Stats/\_status). (shows 957 mb ) But upon checking manually , the disk space was not getting freed up . So, i tried optimization . Although the optimization operation response was successful, the disk space didn't get free. By reffering to this link ;- [http://elasticsearch-users.115913.n3.nabble.com/When-does-ES-free-up-disk-space-td2601270.html](http://elasticsearch-users.115913.n3.nabble.com/When-does-ES-free-up-disk-space-td2601270.html) i tried using the curl command - curl -XPOST '192.168.145.117:9200/\_optimize?only\_expunge\_deletes=true' Although the command was run successfully , but , the response was {"ok":true,"\_shards":{"total":5,"successful":4,"failed":0}} 1 shard not either successful, nor failed. I checked the stats/status API, the size it refleced was reduced , but disk size was still the same. Also , it reflected the same number of shards (successful = 4) . After deletion when ES shows 4 successful shards , the size of the 5th shard is (1.1 GB -957 MB). Physically , all the 5 shards are present in the data directory. Upon restarting the ES instance , it again shows( Stats/Status API) , 5 successful shards , and the data size is again back to 1.1 GB. I am using elasticsearch-0.90.0.RC2 . Please help me .Where am i going wrong ? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
