I have 3 node and config setup as shown below in all 3 es server. If anyone has similar fail over issue, please let me how did you resolved. I am implementing first time in Oracle PeopleSoft application. elasticsearch.yml server1 discovery.zen.minimum\_master\_nodes: 1 node.master: true node.data: true server2 discovery.zen.minimum\_master\_nodes: 1 node.master: true node.data: true server3 discovery.zen.minimum\_master\_nodes: 1 node.master: true node.data: true ---

The fail over not working. When I shut down server1 (Node1) the ES does not switch automatically to either of the 2 additional node in cluster. Thanks Qamar ---

That does not answer my question. What is the elasticsearch client or library which is used by Peoplesoft to connect to elasticsearch cluster? Anyway, here is what you can do: - Ask Peoplesoft support - Add a Load Balancer (LB) in front of elasticsearch nodes but if the LB fails you will have the same issue - Add a coordinating only node (master and data: false) and connect Peoplosoft to this node. But same as previous, if it fails, you will have the same issue. Most of elasticsearch clients are supporting using multiple nodes, like the Java REST Client, Logstash or Beats. ---

> [@qamarjrk](#): > > discovery.zen.minimum\_master\_nodes: 1 If you have 3 master eligible nodes in the cluster, you need to set `discovery.zen.minimum_master_nodes` to 2 in order to avoid split-brain scenarios and data loss.

I have setup as as you mention earlier. discovery.zen.ping.unicast.hosts: ["[server1.pttmor.org](http://server1.pttmor.org)", "[server2.pttmor.org](http://server2.pttmor.org)", "[server3.pttmor.org](http://server3.pttmor.org)"] discovery.zen.minimum\_master\_nodes: 2 My question is do I need to keep same in all 3 server? Thanks for you all help. ---

You did that in the server. Not on the client side. ---

I can't access to your private network I think. But I guess you are using that: [https://blogs.oracle.com/peopletools/elasticsearch-for-peoplesoft-now-available](https://blogs.oracle.com/peopletools/elasticsearch-for-peoplesoft-now-available) May be it's better to ask Oracle about how to configure this tool? ---

This is my current setup, but when i shut down server 1 search did not work. Seems like cluster not working. # Server1 # node.master: true # node.data: true # Server2 node.master: true # node.data: true # Server3 node.master: true # node.data: true ---

Please format your code using `` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button. It will make your post more readable. Or use markdown style like: ```` ``` CODE ``` ```` Please edit your post and share the logs of the 3 nodes. What gives `GET _cat/nodes?v` on one of the nodes which is still running? ---
