{timestamp:2024-11-25T15:25:39.730Z, log.level: WARN, message:This node is a fully-formed single-node cluster with cluster UUID [CHfiZM08TKimVoEvLnfBbw],
but it is configured as if to discover other nodes and form a multi-node cluster via the [discovery.seed_hosts[elasticsearch-headless]] setting.
Fully-formed clusters do not attempt to discover other nodes, and nodes with different cluster UUIDs cannot belong to the same cluster.
The cluster UUID persists across restarts and can only be changed by deleting the contents of the nodes data path(s). Remove the discovery configuration to suppress this message., ecs.version: 1.2.0,service.name:ES_ECS,event.dataset:elasticsearch.server,process.thread.name:elasticsearch[elasticsearch-0][cluster_coordination]
[T#1],log.logger:org.elasticsearch.cluster.coordination.Coordinator,elasticsearch.cluster.uuid:CHfiZM08TKimVoEvLnfBbw,elasticsearch.node.id:1HTqcojWQxGciuVa71gb-g,elasticsearch.node.name:elasticsearch-0,elasticsearch.cluster.name:elasticsearch}kubectl edit sts elasticsearch
#去掉以下部分
name: discovery.seed_hosts
value: elasticsearch-headless
2.修改后报错服务和集群uuid绑定无法加入新集群
此时需要清除数据目录让其重新运行
注意生产环境需慎重
{timestamp:2024-11-26T09:50:06.905Z, log.level: WARN, message:this node is locked into cluster UUID [xxx]
but [cluster.initial_master_nodes] is set to [elasticsearch-0]; remove this setting to avoid possible data loss caused by subsequent cluster bootstrap attempts;
for further information see https://www.elastic.co/guide/en/elasticsearch/reference/8.11/important-settings.html#initial_master_nodes, ecs.version:
1.2.0,service.name:ES_ECS,event.dataset:elasticsearch.server,process.thread.name:main,
log.logger:org.elasticsearch.cluster.coordination.ClusterBootstrapService,elasticsearch.node.name:elasticsearch-0,elasticsearch.cluster.name:elasticsearch}
3.若有重要数据需要备份数据目录
#删除前请按需备份数据
kubectl scale --replicas0 sts elasticsearch
kubectl delete pvc elasticsearch-elasticsearch-0
kubectl scale --replicas1 sts elasticsearch
4.等待pod重建后已正常
