Mongodb 启动mongos失败

我在不同的服务器上有三个mongod shard进程和三个mongod配置服务器

部署：

服务器192.168.2.101、192.168.2.102192.168.2.163上的ShardA和三个碎片是副本集，192.168.2.102是仲裁器

配置： A.192.168.2.101

XXXX@ubuntu:~$ ps aux | grep mongo

我在服务器192.168.2.102上启动mongos，但启动失败

命令是：

sudo mongos -configdb 192.168.2.101:20000,192.168.2.163:20000,192.168.2.102:20000 -port 30000 -chunkSize 256 -logpath $LOGPATH/mongos.log -logappend -fork

日志输出为：

错误信息是：配置服务器192.168.2.101:20000和192.168.2.163:20000不同，这是什么意思

谢谢

三个配置服务器的内容必须相同。在你的情况下，他们不是。这些配置服务器的历史记录是什么？以前是否使用过dbpath/var/lib/mongodb/config？如果您试图在路径中配置一些数据，可能会出现这样的错误。谢谢Srivatsa N。我删除了旧数据，工作正常。
