 Description   

I directly used tar to pack the whole directory of my running mongod instance, the mongo directory contains my dbpath with jounal enabled. But when I  copy my tar package to another volumn and want to restart the mongod instance, it fails. I know that there must be somet corruption happened since I didn't stop mongo writing when I tar the underlying data  files. Here I post the WiredTiger err log which append when I try to use WiredTiger command utils to salvage my dataset collection. It is almost the same err when I try "-repair"
