我正在做mongodump --host=replicasetname/host,host,host -d databasename --out=path，它工作正常，永远。

但是我已经制作了一个新的副本集，当我这样做时，我什么也得不到。

当它起作用时会发生这种情况：

out 文件夹已创建，但它是空的。

没有显示错误。数据库存在，它包含集合和文档

他们的配置虽然不同

这个有效

{
    "settings" : {
        "chainingAllowed" : true,
        "heartbeatTimeoutSecs" : 10,
        "getLastErrorModes" : {

        },
        "getLastErrorDefaults" : {
            "w" : 1,
            "wtimeout" : 0
        }
    }
}

这个其他不{“protocolVersion”：NumberLong（1），“settings”：{“chainingAllowed”：true，“heartbeatIntervalMillis”：2000，“heartbeatTimeoutSecs”：10，“electionTimeoutMillis”：10000，“getLastErrorModes”：{

        },
        "getLastErrorDefaults" : {
            "w" : 1,
            "wtimeout" : 0
        }
    }
}

这里发生了什么？我能做些什么？

谢谢
