Hi all, I tried to setup 3 Elasticsearch nodes with configuration below - file /etc/hosts (on 3 nodes) ![image](https://us1.discourse-cdn.com/elastic/original/3X/a/1/a12b0c5370f3e2432329d5bbce6214db295aa914.png) - elasticsearch.yml NODE 1 (master-1) cluster.name: es-cluster node.name: "master-1" node.master: true node.data: true path.data: /home/elasticsearch/elasticsearch-7.12.0/data path.logs: /home/elasticsearch/elasticsearch-7.12.0/logs network.host: [_local_, _site_] discovery.seed\_hosts: ["172.19.11.74", "172.19.11.75", "172.19.11.76"] cluster.initial\_master\_nodes: ["master-1", "master-2", "master-3"] NODE 2 (master-2) cluster.name: es-cluster node.name: "master-2" node.master: true node.data: true path.data: /home/elasticsearch/elasticsearch-7.12.0/data path.logs: /home/elasticsearch/elasticsearch-7.12.0/logs network.host: [_local_, _site_] discovery.seed\_hosts: ["172.19.11.74", "172.19.11.75", "172.19.11.76"] cluster.initial\_master\_nodes: ["master-1", "master-2", "master-3"] NODE 3 (master-3) cluster.name: es-cluster node.name: "master-3" node.master: true node.data: true path.data: /home/elasticsearch/elasticsearch-7.12.0/data path.logs: /home/elasticsearch/elasticsearch-7.12.0/logs network.host: [_local_, _site_] discovery.seed\_hosts: ["172.19.11.74", "172.19.11.75", "172.19.11.76"] cluster.initial\_master\_nodes: ["master-1", "master-2", "master-3"] I expect to get 3 node with both master and data role in a cluster but this is the result when I get information on each node (only 1 node in cluster) ![image](https://us1.discourse-cdn.com/elastic/original/3X/c/e/ce5669e5924955989c5b95c8bf016f07bfcc6947.png) Can you guys have any advice for my configuration ?, tks ---

The configuration looks ok now, but I think you used a different configuration earlier that has got you stuck. The simplest thing to try is to delete `/home/elasticsearch/elasticsearch-7.12.0/data` on all the nodes and try again. See [these docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-bootstrap-cluster.html#modules-discovery-bootstrap-cluster-joining) for more information. ---
