If mongos detects that config servers are different, metadata should not be changed.
- Ongoing split/moveChunks operations can lead to the full inconsistency if the first config is corrupted for some reason;
- Ongoing metadata changes can mask the original issue
I checked manually with 2.4.1, and I could do manual splitAt and moveChunk, while my second config server was out of sync.
