etcd集群搭建报报错：request cluster ID mismatch (got
目前在学习K8S, etcd 集群搭建，启动时候报错：
master-16 etcd[25461]: request cluster ID mismatch (got bdd7c7c32bde1208 want 698851d67fea3c17)

解决办法：删除了etcd集群所有节点中的--data_dir配置的数据存储目录下所有数据如：/datasoft/soft/etcd_v3.3.12/default.etcd/
分析： 因为集群搭建过程，单独启动过单一etcd,做为测试验证，集群内第一次启动其他etcd服务时候，是通过发现服务引导的，所以需要删除旧的成员信息
