Hi, I am using elasticsearch cluster (8.7.0) on Kubernetes, I have 1 master, 1 client and 3 data nodes. After the restart of my master node, the other nodes cannot discover the master again. This is in the log of the data node: ```auto {"@timestamp":"2023-05-31T12:38:36.905Z", "log.level": "WARN", "message":"master not discovered yet: have discovered

Yes, they are.

I don't have path.data in my elasticsearch.yaml file, can that be the problem why my data path did not persist across its restart? I only have persistent volume which is mount in my deployment: ```auto volumeMounts: ... - mountPath: /data name: elasticsearch-master-pvc ... volumes: ... - name: elasticsearch-master-pvc persistentVolumeClaim: claimName: elasticsearch-master-pvc ... ``` And this is my elasticsearch.yaml file: ```auto cluster.name: ${CLUSTER_NAME} node.name: ${NODE_NAME} discovery.seed_hosts: ${NODE_LIST} network.host: 0.0.0.0 node.roles: ["data"] xpack.monitoring.collection.enabled: true xpack.security.enabled: true xpack.security.transport.ssl.enabled: true xpack.security.transport.ssl.verification_mode: certificate xpack.security.transport.ssl.keystore.path: /usr/share/elasticsearch/config/certs/elastic-certificates.p12 xpack.security.transport.ssl.truststore.path: /usr/share/elasticsearch/config/certs/elastic-certificates.p12 xpack.security.http.ssl.enabled: false xpack.security.http.ssl.truststore.path: /usr/share/elasticsearch/config/certs/elastic-certificates.p12 xpack.security.http.ssl.keystore.path: /usr/share/elasticsearch/config/certs/elastic-certificates.p12 ``` ---

Sounds like a plausible explanation indeed. Is Elasticsearch writing anything to that PVC? Definitely best to set `path.data` anyway. ---

Anywhere that persists across restarts will do. You mentioned `mountPath: /data` above which suggests that anything under `/data` will work. ---
