Hi ,

Recently we created 3 nodes in a cluster because of some reason we want to remove those nodes and bring our elasticsearch to old state (without nodes).

how to do this by not loosing any data?

Thanks in Advance.

The easiest thing to do is take down one node, wait for the cluster to re-balance the shards across the existing nodes, take down the next node, etc.

Edit: ^^^^ this assumes you have at least one replica for each index. If you don't have replicas, you'll have to use shard filtering below vvv

Alternatively, you could use [Shard Allocation Filtering](https://www.elastic.co/guide/en/elasticsearch/reference/current/shard-allocation-filtering.html) to exclude all your indices from the target nodes, wait for the cluster to rebalance, then take down the nodes.

Make sure you update [`minimum_master_nodes` as appropriate](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/modules-discovery-zen.html#master-election)
