我在the official tutorial之后使用三个配置服务器，副本集中的三个服务器以及使用mongos客户端创建共享集群，但是当我尝试使用
创建集合时db.createCollection("XYZ")
我得到了
/* 1 */

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

我的服务器状态为

我做错了什么？
提前致谢。
答案 0 :(得分：2)
回答我自己的问题，这真的是假的问题。问题在于，因为配置服务器是副本集，所以副本集和分片副本集之间的名称必须是唯一的，在我的情况下，不会导致问题。
