Hi,
I have created a cluster with two nodes.
Config on server1:
```auto
cluster.name: app.elasticsearch.prod
node.name: app.elasticsearch.prod.prod01
```
Config on server2:
```auto
cluster.name: app.elasticsearch.prod
node.name: app.elasticsearch.prod.prod02
```
I have stopped elasticsearch one server at a time couple of times for config modifications.
In head plugin of each server, I see the only one local elasticsearch.
**Data is in sync**. **But seems like both are trying to be master nodes.**
How can I resolve this?
Thanks.

I know I can set in one of the configuration that it cannot be master node.
But then I can't bounce the elasticsearch as there might be missing master node.
Please suggest.

What does the rest of your config (minus comments) look like?

All other config is default except this:
```auto
path.conf: ${ELASTIC}/conf
path.data: ${ELASTIC}/data
path.logs: ${ELASTIC}/logs
path.plugins: ${ELASTIC}/plugins
```

Big ++ on that last one.
Also take a look at [https://www.elastic.co/guide/en/elasticsearch/guide/current/\_important\_configuration\_changes.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/_important_configuration_changes.html)

Thanks @mosiddi, it worked.
@warkolm, We have only two servers in the cluster, and I see the recommendation to use 3 servers and quorum of 2.
Currently minimum\_master\_nodes is 1. Can we continue using this setting?

You can but you are at greater risk of split brain.

Yes. We see the risk. Planning to add another server to the production to avoid it.
Thanks for your inputs.
