Hey,

I have 3 elasticsearch nodes (2 hot and 1 cold\_data at the moment). I receive logs from logstash and store them in hot nodes. I would like move "old" logs with ILM to cold\_data nodes, but when I start cold\_data node, then all hot nodes are rebalancing and put some replica shards to cold\_data node.

I tried `cluster.routing.allocation.exclude._ip: "cold_data_node_ip"` in cold data node config, but ILM cannot move the primary shards too to node.

How can I disable that, cluster do not move replica shard to cold data node?

you need to filter at index level

index.routing.allocation.exclude.\_name

> **[Shard Allocation Filtering | Elasticsearch Reference \[6.8\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/shard-allocation-filtering.html)**

and when data pass to cold phase remove filter .
