comment Recovering data from MongoDB raw files
You can't mix & match database files from different instances of MongoDB; doing so will almost certainly guarantee instability and potential data loss. What state are your data files in now? Were you able to recover from this issue?

comment How to check if mongodb metadata's integrity?
The balancer will not run without all config servers available, so the sharded cluster metadata is implicitly read-only if one or more servers are unavailable. The error message is expected: you can stop of your remaining config servers, do the file copy, and then start up the config servers to resume normal operation. If you were doing planned maintenance you could stop the balancer before taking down a config server, which would try to complete any migration in progress before stopping the balancer.
