Disable replica shard on cold data node?

Elastic Stack Elasticsearch
1

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

and when data pass to cold phase remove filter .
