I have setup ILM policy with shrink but not working. what am I missing

```auto
PUT _ilm/policy/metricbeat
{
  "policy": {
    "phases": {
      "hot": {
        "min_age": "0ms",
        "actions": {
          "rollover": {
            "max_size": "120gb",
            "max_age": "30d"
          }
        }
      },
      "warm": {
        "min_age": "30d",
        "actions": {
          "set_priority": {
            "priority": 50
          },
          "shrink": {
            "number_of_shards": 2
          },
          "allocate": {
            "number_of_replicas": 0
          }
        }
      }
    }
  }
}

```

I also want this to move to warm node which I have define via Elasticsearch.yml

```auto
# grep node.role /etc/elasticsearch/elasticsearch.yml
node.roles: [data_warm]

```

this does not seems to be taking place. which step did I miss.  
ILM policy is being executed because my data has 0 replica

How many shards does your index originally have?

Do you have anything in the logs, probably the in the master node logs?

What happens when you try to shrink the index using the shrink API, any error? Can you try that?
