mongodb分片群集错误14037

Question

我将根据官方教程使用三个配置服务器，副本集中的三个服务器并使用mongos客户端创建共享集群，但是当我尝试使用以下方法创建集合时

db.createCollection("XYZ")

我懂了

/* 1 */
{
    "ok" : 0.0,
    "errmsg" : "can't create user databases on a --configsvr instance",
    "code" : 14037,
    "codeName" : "Location14037"
}

我的服务器状态是

/* 1 */

我究竟做错了什么？

提前致谢。

回答我自己的问题，这确实是个问题。 事实是，因为配置服务器是一个副本集，所以该副本集和分片副本集之间的名称必须唯一，在我的情况下不是唯一的，这会导致问题。
