Hello everyone! I'm trying to deploy ES v 8.6.2 on a Kubernetes cluster in a single-node configuration, and having troubles with the data storage on bootstrap. I'm deploying ES as a StatefulSet (replicas: 1) with indexing type NIOFS, and the storage space is requested to a StorageClass via a volumeClaimTemplate in the definition of the StatefulSet, with accessMode: "ReadWriteOnce". This is the error I'm getting: ```auto 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? ``` followed by the chain of exceptions raised, and then this: ```auto Caused by: java.nio.file.NoSuchFileException: /usr/share/elasticsearch/data/node.lock ``` On the Kubernetes cluster there is already another ES node, belonging to another ES cluster, but the two nodes (mine and the already existing one) are using totally different volumes, so there shouldn't be any conflict in that sense. Besides, I cannot create/request a separate namespace, so the two should live under the same namespace. What could be the cause of the error? If it's something regarding not having the right privileges to read/write, how can I solve this without escalating to root? The K8s cluster I'm working on does not allow for privileged/root containers. Thanks in advance * * * Edit: this is the complete log generated by elasticsearch before crashing (I removed the timestamps, since they are not very meaningful) ```auto Created elasticsearch keystore
