Elasticseach - Shards allocation error

After follow the Guidelines from Elastic documentation. In order to recover unassigned shard on TEST Env elasticsearch cluster. I got this error..

" {"error":"RemoteTransportException[[node01][inet[/ipaddess:9300]][cluster:admin/reroute]]; nested: ElasticsearchIllegalArgumentException[[allocate] trying to allocate a primary shard [.shardname1][0], which is disabled]; ","status":400} "

Resolved with ...

"
#!/bin/bash
for shard in $(curl -XGET http://localhost:9200/_cat/shards | grep UNASSIGNED | awk '{print $2}'); do
  # This have to be commented
  curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
    "commands": [
      {
      "allocate": {
          "index": "index_name",
          "shard": 1,
              "node": "node1",
              "allow_primary": true
          }
        }
    ]
  }'
  sleep 5
done

"

So, I would like to ask you whether, I should try to recover the data or just disable it at all.

:-) Dont worry I managed to fix it and re-assigned the shards ...
