Hi All, I am starting up 3 elasticsearch services to try to utilise the large amount of memory my server has (~390GB). I have just made copy's of the /etc/init.d script and changed them to point to their own configuration file. Then ran update-rcd to ensure they run on boot.. I can see the 3 processes running all pointing to there own config files. Each configuration file has the same cluster name ################################### Cluster ################################### # Cluster name identifies your cluster for auto-discovery. If you're running # multiple clusters on the same network, make sure you're using unique names. # cluster.name: elasticsearch However I've given them different Node names. i.e Node1, Node2 and Node3 #################################### Node ##################################### # Node names are generated dynamically on startup, so you're relieved # from configuring them manually. You can tie this node to a specific name: # node.name: Node1 However when I when I running 'curl localhost:9200/\_nodes/process?pretty' I notice they all have the same Node Name.... is that correct? Also does everything else look ok? { "cluster\_name" : "elasticsearch", "nodes" : { "h74xaIssRkui4\_jO-kwsfA" : { "name" : "Node1", "transport\_address" : "inet[/10.166.132.11:9302]", "host" : "msi-n-logz-1", "ip" : "10.166.132.11", "version" : "1.4.2", "build" : "927caff", "http\_address" : "inet[/10.166.132.11:9202]", "attributes" : { "master" : "true" }, "process" : { "refresh\_interval\_in\_millis" : 1000, "id" : 1892, "max\_file\_descriptors" : 65535, "mlockall" : false } }, "8fhp\_JSCRZS27gdXNa8KDg" : { "name" : "Node1", "transport\_address" : "inet[/10.166.132.11:9301]", "host" : "msi-n-logz-1", "ip" : "10.166.132.11", "version" : "1.4.2", "build" : "927caff", "http\_address" : "inet[/10.166.132.11:9201]", "attributes" : { "master" : "true" }, "process" : { "refresh\_interval\_in\_millis" : 1000, "id" : 1660, "max\_file\_descriptors" : 65535, "mlockall" : false } }, "\_-R2UbIoQNurnZA8\_ibLxg" : { "name" : "Node1", "transport\_address" : "inet[/10.166.132.11:9300]", "host" : "msi-n-logz-1", "ip" : "10.166.132.11", "version" : "1.4.2", "build" : "927caff", "http\_address" : "inet[/10.166.132.11:9200]", "attributes" : { "master" : "true" }, "process" : { "refresh\_interval\_in\_millis" : 1000, "id" : 1636, "max\_file\_descriptors" : 65535, "mlockall" : false } }, "xPNfdj-rR\_SrEbgpxwdWEg" : { "name" : "logstash-msi-n-logz-1-625-2018", "transport\_address" : "inet[/10.166.132.11:9303]", "host" : "msi-n-logz-1", "ip" : "10.166.132.11", "version" : "1.1.1", "build" : "f1585f0", "attributes" : { "client" : "true", "data" : "false" }, "process" : { "refresh\_interval\_in\_millis" : 1000, "id" : 625, "max\_file\_descriptors" : 65535, "mlockall" : false } } } } Many thanks! -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Anyone? I'm sorry if this is a silly question, I'm still trying to get my head around this.

I'd say there is still something referring to the old config file.
