Hello.

I have to reboot one of my 3 node cluster node and now one index is in the yellow state .

```
curl -XGET localhost:9200/_cluster/health/my_index | jq '.'
{
  "cluster_name": "cl1",
  "status": "yellow",
  "timed_out": false,
  "number_of_nodes": 3,
  "number_of_data_nodes": 3,
  "active_primary_shards": 5,
  "active_shards": 8,
  "relocating_shards": 0,
  "initializing_shards": 0,
  "unassigned_shards": 2,
  "delayed_unassigned_shards": 0,
  "number_of_pending_tasks": 0,
  "number_of_in_flight_fetch": 0,
  "task_max_waiting_in_queue_millis": 0,
  "active_shards_percent_as_number": 96.7741935483871
}

```

What does it mean "active\_shards\_percent\_as\_number": 96.7741935483871 ?

And how can I get green state ?

As long as all your nodes are using exactly the same version of Elasticsearch and there is enough space on disk this should fix itself. You can use the [cluster allocation explain API](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/cluster-allocation-explain.html) to find out why the missing shards are not assigned.

Yes. Thanks.  
Fixed by curl -XPOST localhost:9200/\_cluster/reroute?retry\_failed=true
