Hi all,  
I'm getting an error when I try to clone my index called `myindex` into `myindex_clone`. I have set up a 3 node cluster on my machine, and I'm using the (Go) SDK client to call the `CloneIndex()` function. However I'm seeing the following error:

```auto
es1 | {"type": "server", "timestamp": "2021-12-08T17:56:59,344Z", "level": "WARN", "component": "o.e.i.c.IndicesClusterStateService", "cluster.name": "es-docker-cluster", "node.name": "es1", "message": "[myindex_clone][0] marking and sending shard failed due to [failed recovery]", "cluster.uuid": "9sYb7rmqQGmRXOLvyLxOxg", "node.id": "rzC7tCbeThypNSAY6KokIg" ,
es1 | "stacktrace": ["org.elasticsearch.indices.recovery.RecoveryFailedException: [myindex_clone][0]: Recovery failed on {es1}{rzC7tCbeThypNSAY6KokIg}{K-JS8W07RkifXim9kF8cQg}{172.28.0.2}{172.28.0.2:9300}{cdhilmrstw}{ml.machine_memory=5175709696, xpack.installed=true, transform.node=true, ml.max_open_jobs=20}",

```

The cluster status becomes red indefinitely. If I try curling the clone API endpoint it seems to work fine:

```auto
curl -X PUT "localhost:9200/myindex/_clone/myindex_clone-1"
{"acknowledged":true,"shards_acknowledged":true,"index":"myindex_clone-1"}

```

This is the result i'm seeing:

```auto
curl -X GET localhost:9200/_cat/indices\?format=json\&pretty
[
  {
    "health" : "green",
    "status" : "open",
    "index" : "myindex_clone-1",
    "uuid" : "CSufysmETAqrhNuGsQd3Ag",
    "pri" : "1",
    "rep" : "1",
    "docs.count" : "0",
    "docs.deleted" : "0",
    "store.size" : "416b",
    "pri.store.size" : "208b"
  },
  {
    "health" : "red",
    "status" : "open",
    "index" : "myindex_clone",
    "uuid" : "Fp_vdgXuSkGXvHYOFOmwiA",
    "pri" : "1",
    "rep" : "1",
    "docs.count" : null,
    "docs.deleted" : null,
    "store.size" : null,
    "pri.store.size" : null
  },
  {
    "health" : "green",
    "status" : "open",
    "index" : "myindex",
    "uuid" : "nFOgoOGwR0K4hpU-gEtyJQ",
    "pri" : "1",
    "rep" : "1",

    "docs.deleted" : "0",
    "store.size" : "416b",
    "pri.store.size" : "208b"
  }
]

```

If I do an erxplain on the cluster I get:

        },
        {

          "decision" : "NO",
          "explanation" : "primary shard for this replica is not yet active"
        }
      ]
    }
  ]
}

```

But I'm unsure what that means exactly. I don't understand why the `curl` request would work while the request via the client SDK doesn't. Can anyone help me fixing this?

I found out why. Turns out i had set the current index to `index.blocks.read_only` when it should be `index.blocks.write`.
