      After the a Hyper-V virtual machine running RHEL and mongod (v3.4.18) shutdown expectantly when the host was patched the database can no longer be started. 

      The last backup was a couple of weeks ago, and was done via Mongodump so I'm unable to recover the original metadata files to attempt to the wt restore method.
      Looking online this appears to occur when the database metadata files have become corrupt, and in the past it's been recommended to upload the attached files incase the developers are able to manually repair them.

      If this is possible it would be much appreciated.
