I was following this [doc](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/indices-shrink-index.html) for decreasing shards but `GET /_cluster/allocation/explain` shows  
`"explanation" : """node does not match index setting [index.routing.allocation.require] filters [_name:"ed1"]"""`  
I want to shrink an index name called elastalert\_status earlier it has 3 primary and 1 replica shard  
now i want to have 2 shards(1P+1R)  
I ran the following commands  
1.

```auto
PUT elastalert_status/_settings
{
  "settings": {
      "index.routing.allocation.require._name": "ed1",
      "index.blocks.write": true,
       "index.number_of_replicas": 0     
  }
}

```

1. 

```auto
POST /elastalert_status/_shrink/elastalert_status_1
{
  "settings": {
     "index.number_of_replicas": 1,
    "index.number_of_shards": 1,
    "index.codec": "best_compression"
  }
}

```

New index name is elastalert\_status\_1  
GET /\_cat/indices/elastalert\_status\_1?v&pretty

````auto
yellow open elastalert_status_1 BShehE1bRdO3DRlOHs1yEQ 1 1 389798 0 266.3mb 266.3mb```
The size of old index was 281.7mb
