As I understand from the documentation, when a node goes down, elastic search _automatically_ creates primary or replica shards on all other nodes to address the failure of the node.

However, what happens if the nodes comes up - will those shards are "automatically" removed created on other node as the machine comes up - say , in a cluster with _3 nodes_ , node 1 which contains 1 primary shard of _index 1_ , and one replica shard of _index 2_ . If node 1 goes down, the ES _automatically_ creates the primary shard , replica shard in either of the available nodes

[This section](https://www.elastic.co/guide/en/elasticsearch/guide/2.x/distributed-cluster.html) is quite old but as far as I can tell still valid, and [this blog post](https://www.elastic.co/blog/every-shard-deserves-a-home) may also be quite useful.
