尝试从主节点同步时，添加的副本集成员在检测到以前的数据时失败

Question

通过删除每个主机上的本地数据库来删除任何旧副本的数据后，启动具有不同 replSetName 的新副本。

尝试添加另一个成员，当尝试从主副本同步并死亡时，它会找到先前副本的历史记录：

如何彻底删除该成员之前的副本集历史记录？为什么它会找到不同 replSetName 的副本集的先前历史记录？？

任何副本集内容都保存在本地数据库中，在未启用复制的情况下运行时已被删除。历史记录还保存在哪里？

任何想法都值得赞赏。

Answer 1

建议的建议很明显，但它正在解决问题。

停止在不复制的情况下添加成员，转到其存储目录并删除所有内容。然后重新启动复制

storage:
  dbPath: /var/lib/mongodb
