Dear elasticsearch team, I have tried all the possible solution but I can't installa e new cluster because no master node could be discovered. My cluster is made by 3 master and 3 data node. Here are the master configurations: NODE01: > ``` > cluster.initial_master_nodes: > - es-ms01 > - es-ms02 > - es-ms03 > cluster.name: es-data > discovery.seed_hosts: > - es-ms01 > - es-ms02 > - es-ms03 > network.publish_host: es-ms01 > node.data: false > node.master: true > node.name: es-ms01 > > #################################### Paths #################################### > > # Path to directory containing configuration (this file and logging.yml): > > path.data: /var/lib/elasticsearch > path.logs: /var/log/elasticsearch > action.auto_create_index: true > > ``` NODE02: > ``` > cluster.initial_master_nodes: > - es-ms01 > - es-ms02 > - es-ms03 > cluster.name: es-data > discovery.seed_hosts: > - es-ms01 > - es-ms02 > - es-ms03 > network.publish_host: es-ms02 > node.data: false > node.master: true > node.name: es-ms02 > > #################################### Paths #################################### > > # Path to directory containing configuration (this file and logging.yml): > > path.data: /var/lib/elasticsearch > path.logs: /var/log/elasticsearch > action.auto_create_index: true > > ``` NODE03: > ``` > cluster.initial_master_nodes: > - es-ms01 > - es-ms02 > - es-ms03 > cluster.name: es-data > discovery.seed_hosts: > - es-ms01 > - es-ms02 > - es-ms03 > network.publish_host: es-ms03 > node.data: false > node.master: true > node.name: es-ms03 > > #################################### Paths #################################### > > # Path to directory containing configuration (this file and logging.yml): > > path.data: /var/lib/elasticsearch > path.logs: /var/log/elasticsearch > action.auto_create_index: true > > ``` DATA01: > ``` > cluster.name: es-data > discovery.seed_hosts: > - es-ms01 > - es-ms02 > - es-ms03 > network.publish_host: es-data01 > node.data: true > node.master: false > node.name: es-data01 > > #################################### Paths #################################### > > # Path to directory containing configuration (this file and logging.yml): > > path.data: /mnt/data01,/mnt/data02,/mnt/data03 > path.logs: /var/log/elasticsearch > action.auto_create_index: true > > ``` DATA02: > ``` > cluster.name: es-data > discovery.seed_hosts: > - es-ms01 > - es-ms02 > - es-ms03 > network.publish_host: es-data02 > node.data: true > node.master: false > node.name: es-data02 > > #################################### Paths #################################### > > # Path to directory containing configuration (this file and logging.yml): > > path.data: /mnt/data01,/mnt/data02,/mnt/data03 > path.logs: /var/log/elasticsearch > action.auto_create_index: true > > ``` DATA03: > ``` > cluster.name: es-data > discovery.seed_hosts: > - es-ms01 > - es-ms02 > - es-ms03 > network.publish_host: es-data03 > node.data: true > node.master: false > node.name: es-data03 > > #################################### Paths #################################### > > # Path to directory containing configuration (this file and logging.yml): > > path.data: /mnt/data01,/mnt/data02,/mnt/data03 > path.logs: /var/log/elasticsearch > action.auto_create_index: true > > ``` I continuously receive this error: `[2019-12-15T17:10:41,826][WARN][o.e.c.c.ClusterFormationFailureHelper] [es-ms01] master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster, and this node must discover master-eligible nodes [es-ms01, es-ms02, es-ms03] to bootstrap a cluster: have discovered [{es-ms01}{ZqCI-_cwQ7iznI9ocOygzA}{IuSN7KoITtSSmmXe2NRR6A}{es-ms01}{10.0.20.111:9300}{ilm}{ml.machine_memory=3973365760, xpack.installed=true, ml.max_open_jobs=20}]; discovery will continue using [10.0.20.112:9300, 10.0.20.113:9300] from hosts providers and [{es-ms01}{ZqCI-_cwQ7iznI9ocOygzA}{IuSN7KoITtSSmmXe2NRR6A}{es-ms01}{10.0.20.111:9300}{ilm}{ml.machine_memory=3973365760, xpack.installed=true, ml.max_open_jobs=20}] from last-known cluster state; node term 0, last-accepted version 0 in term 0` Just in case could help: java is correctly binded on tcpv4 on port 9200 and 9300 > ``` > tcp 0 0 127.0.0.1:9200 0.0.0.0:* LISTEN 994 132983 28897/java > tcp 0 0 127.0.0.1:9300 0.0.0.0:* LISTEN 994 132941 28897/java > > ``` Firewall is open on those ports via service elasticsearch: > ``` > public > target: default > icmp-block-inversion: no > interfaces: > sources: > services: dhcpv6-client elasticsearch ssh > ports: > protocols: > masquerade: no > forward-ports: > source-ports: > icmp-blocks: > rich rules: > > ``` I have finished the ideas here, I am stuck !!!!

I got the problem !!!!! java was binded to localhost!!! I have noted the error only reading the post to this forum. Adding the option: > network.bind\_host: 0.0.0.0 with the option of the Java VM to prefer ipv4 over ipv6: > -Djava.net.preferIPv4Stack=true And now I have my cluster working 😄 > { > "cluster\_name" : "es-data", > "status" : "green", > "timed\_out" : false, > "number\_of\_nodes" : 6, > "number\_of\_data\_nodes" : 3, > "active\_primary\_shards" : 0, > "active\_shards" : 0, > "relocating\_shards" : 0, > "initializing\_shards" : 0, > "unassigned\_shards" : 0, > "delayed\_unassigned\_shards" : 0, > "number\_of\_pending\_tasks" : 0, > "number\_of\_in\_flight\_fetch" : 0, > "task\_max\_waiting\_in\_queue\_millis" : 0, > "active\_shards\_percent\_as\_number" : 100.0 > } Thanks, Stefano ---
