Hello Team, I have installed ECK Operator(v2.11.1). Installation of the operator is successful. If I am creating Elasticsearch cluster via an operator, pods are getting crashed with following error: {"@timestamp":"2024-02-12T20:52:58.133Z", "log.level":"ERROR", "message":"fatal exception while booting Elasticsearch", "ecs.version": "1.2.0","service.name":"ES\_ECS","event.dataset":"elasticsearch.server","process.thread.name":"main","log.logger":"org.elasticsearch.bootstrap.Elasticsearch","elasticsearch.node.name":"quickstart-es-default-0","elasticsearch.cluster.name":"quickstart","error.type":"java.lang.IllegalStateException","error.message":"failed to obtain node locks, tried [/usr/share/elasticsearch/data]; maybe these locations are not writable or multiple nodes were started on the same data path?","error.stack\_trace":"java.lang.IllegalStateException: failed to obtain node locks, tried [/usr/share/elasticsearch/data]; maybe these locations are not writable or multiple nodes were started on the same data path?\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.env.NodeEnvironment.(NodeEnvironment.java:296)\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.node.NodeConstruction.validateSettings(NodeConstruction.java:484)\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.node.NodeConstruction.prepareConstruction(NodeConstruction.java:246)\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.node.Node.(Node.java:181)\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.bootstrap.Elasticsearch$2.(Elasticsearch.java:236)\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.bootstrap.Elasticsearch.initPhase3(Elasticsearch.java:236)\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:73)\nCaused by: java.io.IOException: failed to obtain lock on /usr/share/elasticsearch/data\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.env.NodeEnvironment$NodeLock.(NodeEnvironment.java:241)\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.env.NodeEnvironment$NodeLock.(NodeEnvironment.java:209)\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.env.NodeEnvironment.(NodeEnvironment.java:288)\n\t... 6 more\nCaused by: java.nio.file.NoSuchFileException: /usr/share/elasticsearch/data/node.lock\n\tat java.base/sun.nio.fs.UnixException.translateToIOException(UnixException.java:92)\n\tat java.base/sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:106)\n\tat java.base/sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:111)\n\tat java.base/sun.nio.fs.UnixPath.toRealPath(UnixPath.java:834)\n\tat org.apache.lucene.core@9.9.2/org.apache.lucene.store.NativeFSLockFactory.obtainFSLock(NativeFSLockFactory.java:94)\n\tat org.apache.lucene.core@9.9.2/org.apache.lucene.store.FSLockFactory.obtainLock(FSLockFactory.java:43)\n\tat org.apache.lucene.core@9.9.2/org.apache.lucene.store.BaseDirectory.obtainLock(BaseDirectory.java:44)\n\tat org.elasticsearch.server@8.12.1/org.elasticsearch.env.NodeEnvironment$NodeLock.(NodeEnvironment.java:234)\n\t... 8 more\n\tSuppressed: java.nio.file.AccessDeniedException: /usr/share/elasticsearch/data/node.lock\n\t\tat java.base/sun.nio.fs.UnixException.translateToIOException(UnixException.java:90)\n\t\tat java.base/sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:106)\n\t\tat java.base/sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:111)\n\t\tat java.base/sun.nio.fs.UnixFileSystemProvider.newByteChannel(UnixFileSystemProvider.java:261)\n\t\tat java.base/java.nio.file.Files.newByteChannel(Files.java:379)\n\t\tat java.base/java.nio.file.Files.createFile(Files.java:657)\n\t\tat org.apache.lucene.core@9.9.2/org.apache.lucene.store.NativeFSLockFactory.obtainFSLock(NativeFSLockFactory.java:84)\n\t\t... 11 more\n"} **What did you expect to see?** Should be able to install Elasticsearch cluster **What did you see instead?
