Hi all,

I am currently having some trouble adding a second node to my ES cluster. I have been at it for a couple of days and doing research, but none of the search hits have yielded me with any positive results.

Running ES in a Windows VM environment as follows:

Win Server 2012 R2 - masternode1 - Original 5.4.0 node - 10.0.140.32  
Win Server 2012 R2 - slavenode1 - new 5.4.0 node to be added to cluster. - 10.0.140.28

This is my elasticsearch.yml file settings for both nodes:

cluster.name: escluster  
node.name: masternode1  
network.host: 10.0.140.32  
http.port: 9200  
discovery.zen.ping.unicast.hosts: ["10.0.140.32","10.0.140.28"]

(#)discovery.zen.minimum\_master\_nodes: 2  
node.master: true  
node.data: true

* * *

cluster.name: escluster  
node.name: slavenode1  
network.host: 10.0.140.28  
http.port: 9200  
discovery.zen.ping.unicast.hosts: ["10.0.140.32","10.0.140.28"]

(#) discovery.zen.minimum\_master\_nodes: 2  
node.master: true  
node.data: true

I understand the ideal setup would be to have 3 node to prevent split brain, but if I'm not mistaken setting both nodes with node.master and node.data to "true" will prevent split brain. Please correct me if this is incorrect. I would like to add a third node to the cluster in the near future, but I need to get two nodes working first.

Things to note:

1. If I remove the comment in front of discovery.zen.minimum\_master\_nodes: 2, it will break Kibana for some reason. I get the error seen below:

1. When I remove the comment in front of discovery.zen.minimum\_master\_nodes: 2, I still see only one node in the cluster when I check 10.0.140.32:9200/\_nodes.

2. I'm not entirely sure if I need any further details in the elasticsearch.yml files for each node to join the new node into the cluster.

Could someone please tell me where I am going wrong. Please try to keep it simple as I haven't been using ES for very long and still learning how to build this system.

Thanks in advanced. Your time is appreciated.
