### Properly configuring Elasticsearch

The default **elasticsearch.yml** set by the Elasticsearch chart expects 2 masters. If using just 1 master replica, there are 3 environment variables which should be set equally to avoid issues starting Elasticsearch.

Set the following environment variables under **elasticsearch.cluster.env**. The Zammad StatefulSet will most likely fail without setting these correctly.

Refer to the Elasticsearch documentation for info on these variables. [[1](https://www.elastic.co/guide/en/elasticsearch/reference/5.6/modules-gateway.html)] [[2](https://www.elastic.co/guide/en/elasticsearch/reference/5.6/modules-node.html#split-brain)]

### Important note for NFS filesystems
For persistent volumes, NFS filesystems should work correctly for **Elasticsearch** and **PostgreSQL**; however, errors will occur if Zammad itself uses an NFS-based persistent volume. Websockets will break completely. This is particularly bad news for receiving notifications from the application and using the Chat module.
Don't use an NFS-based storage class for Zammad's persistent volume.
