I'm running an Elasticsearch 7.3.2 cluster, which was recently bootstrapped with 3 nodes:

- [elastic1.domain.com](http://elastic1.domain.com)
- [elastic2.domain.com](http://elastic2.domain.com)
- [elastic3.domain.com](http://elastic3.domain.com)

The cluster was running well until yesterday when I needed to make a full cluster shutdown.

Now the cluster is not running and /\_cat/health calls on every node returns status 503:

```
{
"error": {
"root_cause": [
{
"type": "master_not_discovered_exception",
"reason": null
}
],
"type": "master_not_discovered_exception",
"reason": null
},
"status": 503
}

```

This is the complete Elasticsearch configuration on all three nodes:

```
cluster.name: mycluster
node.name: elasticX.domain.com
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: 0.0.0.0
http.port: 9200
discovery.seed_hosts: ["elastic1.domain.com", "elastic2.domain.com", "elastic3.domain.com"]
cluster.initial_master_nodes: ["elastic1.domain.com", "elastic2.domain.com", "elastic3.domain.com"]

```

Could you help me to understand where I'm wrong, and how I can recover my cluster, please?

Is the storage used persistent?

Yes, it is.  
Nodes are installed on local storage and not in containers like Dockers.

Did any firewall rules change?

No, nodes can correctly see each others and there are no blocking firewall rules.
