      I only backup my whole mongo directory without stopping the mongod instance, after finishing the System initialization, I returned mongo directory and try "bin/mongod -f mongo.conf", it fails. Then I check the mongo.log and find out that these must be some corruption happened. I tried "repair" and it fails with the log bellow. I also tried WiredTiger tools and it fails with almost same err. please help me. Dataset here is very important for me .
