Hello, I've a simple question, is there a way to move a specific shard from a node to a specific other node ? For example, if I don't want a to have any replicas, and my data is set as many shards on many nodes: NODE1: SHARD1,SHARD4 NODE2: SHARD2,SHARD5 NODE3: SHARD3,SHARD6 If I shutdown the NODE3, SHARD3 and SHARD6 will be unavailable. How can I move SHARD3 to NODE1, and SHARD6 to NODE2 _without_ setting replica=1 to this index ? Thanks ! -- Erwan ---

Probably I don't properly understand your usecase, but if you have replica\>1 then there is no problem with removing the node3 as the shards are already replicated (at least once) to another node(s), no?

It is possible in master (upcoming 0.18): [Cluster / Index level allocation filtering · Issue #1311 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/issues/1311), by excluding that relevant node for shard allocation (can be done also based on IP, see at the bottom of the issue).

Hello Shay, Thanks for the answer, this feature is what I was looking for.
