Hi We have a 7 node ES cluster (v7.17.5) and we need to change the hostnames of all nodes. I know how to do it on Linux, but, is there anything I need to change on Elasticsearch? My elasticsearch.yml uses ip address (not hostnames), and we are not changing ips. For example: discovery.seed\_hosts: ["10.57.40.167", "10.57.40.168", "10.57.40.169", "10.57.40.136", "10.57.40.137"] But I see now two parameters which do use node name: xpack.security.transport.ssl.keystore.path: certs/${node.name}.p12 xpack.security.transport.ssl.truststore.path: certs/${node.name}.p12 Thanks ---

List the settings in the [keystore](https://www.elastic.co/guide/en/elasticsearch/reference/current/elasticsearch-keystore.html#list-settings) to see if you have something like this. ```auto /usr/share/elasticsearch/bin/elasticsearch-keystore list ``` ---

Hi The command returns: # /usr/share/elasticsearch/bin/elasticsearch-keystore list keystore.seed But I'm not worried about that parameter, what I'm asking if I need to change something in the Elastic Cluster when I'm changing the system hostname... Thanks ---

The system hostname is only used if you do not set the `node.name` in `elasticsearch.yml`, if you have set it, then it is irrelevant what is the hostname. Also, the node name is just a human-readable identifier of the node, to know which node is which the uuid generated when started the node for the first time is used. ---
