What trouble are you having? And how are you installing elasticsearch? Since you are trying to run two different versions on the same server, I would recomend that you install them using the `.tar.gz.` package to avoid confusion. ---

Hi @leandrojmp Thanks for your reply on my case. I am trying to installing both Elasticsearch packages through an .tar.gz file only. i was able to configure ELS 6.8 having a following context in my elasticsearch.yml file. cluster.name: elastic\_68 # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # node.name: node-1 node.master: true node.data: true transport.host: localhost transport.tcp.port: 9300 http.port: 9200 network.host: 0.0.0.0 Below is the context of a ELS 7.9 elasticsearch.yml file. cluster.name: elastic\_68 # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # node.name: node-2 node.data: true transport.host: localhost transport.tcp.port: 9302 http.port: 9202 network.host: 0.0.0.0 When i am trying to start the elasticsearch 7.9, i am receiving following errors on the terminal screen. ktpl@ubuntu ~/elasticsearch-7.9.2 bin/elasticsearchv7 -d future versions of Elasticsearch will require Java 11; your Java version from [/usr/lib/jvm/java-8-openjdk-amd64/jre] does not meet this requirement future versions of Elasticsearch will require Java 11; your Java version from [/usr/lib/jvm/java-8-openjdk-amd64/jre] does not meet this requirement ktpl@ubuntu ~/elasticsearch-7.9.2 uncaught exception in thread [main] java.lang.IllegalStateException: failed to obtain node locks, tried [[/home/ktpl/elasticsearch-7.9.2/data]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max\_local\_storage\_nodes] (was [1])? at org.elasticsearch.env.NodeEnvironment.(NodeEnvironment.java:301) at org.elasticsearch.node.Node.(Node.java:344) at org.elasticsearch.node.Node.(Node.java:277) at org.elasticsearch.bootstrap.Bootstrap$5.(Bootstrap.java:227) at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:227) at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:393) at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:170) at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:161) at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:127) at org.elasticsearch.cli.Command.main(Command.java:90) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:126) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:92) For complete error details, refer to the log at /home/ktpl/elasticsearch-7.9.2/logs/elastic\_68.log Can you please let me know which these error means? should i run the els service through an Elasticsearch user only?

> [@hemangc](#): > > Java.lang.IllegalStateException: failed to obtain node locks, tried [[/home/ktpl/elasticsearch-7.9.2/data]] with lock id [0] It seems to be already a instance running writing to this data dir, can you check it? Also, I would recommend that you explicitly set the `path.data` and `path.logs` to [different directories](https://www.elastic.co/guide/en/elasticsearch/reference/master/path-settings.html) in each one of your nodes. You are also using the same `cluster.name` for your nodes, you can't do that, they need to have different a `cluster.name`. ---
