扩容节点后数据库消失

[liarby]

Kubernetes version: v1.26.0(KubeSphere：v3.4.1) Helm version: v3.12.0 RadonDB Operator version: 3.0.0 RadonDB MySQL version: 8.0.25

数据库集群节点从1节点扩到3节点后，创建的数据库消失 操作过程： 1、检查1节点集群状态

2、创建数据库

3、将集群节点扩容到3个 [root@k8s-master001 ~]# kubectl get all -n mysql-cluster NAME READY STATUS RESTARTS AGE pod/radondb-operator-mysql-operator-846657db5-xsb6v 2/2 Running 0 45h pod/sample-mysql-0 3/3 Running 0 87s pod/sample-mysql-1 3/3 Running 0 3m43s pod/sample-mysql-2 3/3 Running 0 2m40s

4、查看数据库

可以看到数据库hx_db已经没有了
