报上面错误的原因疑似最新版2.2.0镜像sha256:be794368c96f90e42a6dd9f288d3fb12d69608cebd782eb091a489ccb48cfd28 里面，没有设置spring.sql.init.platform=${SPRING_DATASOURCE_PLATFORM:} 默认值mysql，手动添加后nacos-0和nacos-1启动成功，nacos-2启动失败 - name: SPRING_DATASOURCE_PLATFORM
value: "mysql"

去掉pvc，三个节点集群是正常的，但是相应的就丧失了动态扩缩容的能力，我们需要这个，能否有人看一下问题，集群+pvc模式的所有日志在上面的压缩包中

k8s版本: 1.20.11-aliyun.1

使用阿里云NAS做的pvc，挂载的nfs3
集群主机连接RDS是可以通的，命名空间中有一个1.4版本的在运行
数据库帐号密码正确，使用的初始化sql为 https://github.com/alibaba/nacos/blob/master/distribution/conf/mysql-schema.sql
