gaoyuanopenfire, your cluster is not balanced because the config servers are out of sync, as the logs point out. You'll need to replace the offending config server to fix your cluster. Here's some documentation on replacing a config server, and also some instructions on fixing out-of-sync config servers. That being said, note that the SERVER project is for reporting bugs or feature suggestions for the MongoDB server and tools. For MongoDB-related support discussion please post on the mongodb-user group or Stack Overflow with the mongodb tag. A question like this involving more discussion would be best posted on the mongodb-user group. |
