HI, I have setup ES-5.6.0 using RPM (on OEL-7.3), I have setup 7-nodes in cluter. Issue: I am able to start the ES services on all 7-nodes but when I am listing cluster nodes using curl command then I am getting on 5-nodes listed. When I am restarting the ES service on all this 7-nodes then cluster is picking random 5-nodes from it, but not all 7-nodes. [root@perf03 x-pack]# curl -XGET -u elastic '[http://172.20.90.60:9200/\_cat/nodes?v](http://172.20.90.60:9200/_cat/nodes?v)' Enter host password for user 'elastic': ip heap.percent ram.percent cpu load\_1m load\_5m load\_15m node.role master name 172.20.90.62 1 59 0 0.05 0.04 0.05 mdi - perf05 172.20.90.63 1 85 0 0.00 0.01 0.05 mdi \* perf06 172.20.90.60 2 90 1 0.00 0.02 0.05 mdi - perf03 172.20.90.64 2 58 0 0.00 0.01 0.05 mdi - perf07 172.20.90.61 1 58 1 0.00 0.01 0.05 mdi - perf04 - elasticsearch.yml file content: [node.name](http://node.name): perf03 (set same as hostname on each node) [cluster.name](http://cluster.name): PERFES5 path.data: /data/es\_data network.host: _ens160:ipv4_ http.port: 9200 transport.tcp.port: 9300 discovery.zen.ping.unicast.hosts: ["perf01:9300", "perf02:9300", "perf03:9300"] discovery.zen.minimum\_master\_nodes: 2 node.max\_local\_storage\_nodes: 2 xpack.security.audit.enabled: true Any help appreciated!!

Check the logs on the nodes that aren't in the cat output, it should state if they are joining or not, and why. ---

You have more than 3 master eligible nodes, which means that minimum\_master\_nodes is incorrectly set. The host list also does not seem to contain all master eligible nodes. ---
