I'm using elasticsearch 5.5.1 in 4 node cluster and I just noticed following:

```
# curl --silent --request GET elk:9200/_cat/health
1505576198 15:36:38 X red 4 4 991 831 0 0 691 0 - 58.9%
# 

```

&

```
# curl --silent --request GET elk:9200/_cat/indices | egrep -v '^(green|yellow)'
red open X-2017.09 hG0-mX0tTwSEKaweqffuyg 5 1                                 
red open Y-2017.06 xIJ-UX2rQI-tSrfwr5oy0Q 5 1                                 
# 

```

I've looked in logs and did not find anything useful, I also tried "Windows approach" (aka restart) all nodes, that did not help either...

How does one address this issue? and mean while, I guess I have some reading to do:

[Cluster Health | Elasticsearch: The Definitive Guide [2.x] | Elastic](https://www.elastic.co/guide/en/elasticsearch/guide/current/_cluster_health.html)  
[RED Elasticsearch Cluster? Panic no longer | Elastic](https://www.elastic.co/blog/red-elasticsearch-cluster-panic-no-longer)

Please advise.

Look in the Elasticsearch logs, it should say why the indices are red.

@alexus index in red state depends on shards not allocate properly due to some configuration issue.  
best way to debug this issue please share elasticsearch logs .
