在2.1多节点安装时
kubectl logs mysql-b5597d996-99mvp -n kubesphere-system

使用的rbd存储，全部删了重安了一次，还是出现相同的情况

您好,看你的ERROR,initialize specified but the data directory has files in it. Aborting.
应该是data目录(/var/lib/mysql)里边有文件需要删除.
可以exec到容器里边手动删除,看是否能解决

describe后看到

应该是执行rm -rf /var/lib/mysql/lost+found 失败了，您知道为什么吗
