Hi, I'm using elasticsearch with graylog. I previously had elasticsearch 2, now I upgraded it to 5. I run it using docker-compose. I'm only using one instance. Here's the service definition:
```
elasticsearch:
restart: always
image: "docker.elastic.co/elasticsearch/elasticsearch:5.6.3"
command: "elasticsearch -Ecluster.name='graylog' -Expack.security.enabled=false"
volumes:
- /home/graylog/.elasticsearch:/usr/share/elasticsearch/data
```
Graylog's System Overview says everything is fine:
> Elasticsearch cluster is green. Shards: 4 active, 0 initializing, 0 relocating, 0 unassigned,
However,
```auto
naftoli@graylog-main:/home/graylog$ curl 172.18.0.3:9200/_cat/health
1509412370 01:12:50 graylog yellow 1 1 9 9 0 0 5 0 - 64.3%
naftoli@graylog-main:/home/graylog$ curl 172.18.0.3:9200/_cat/nodes
172.18.0.3 10 64 8 0.08 0.43 0.66 mdi * 0bjKb6g
```
Here are the logs: [elasticsearch.log ยท GitHub](https://gist.github.com/nafg/07b5c951b2566a37aec074c0f405da31)
Note the ClusterBlockException.
How to proceed?
Thanks.
