    Description

      Problem Description: 

      We had an unexpected shutdown and are unable to access our Mongo database.  We have been accessing the database from a mongo image pulled from Docker and run in a container in Rancher.  Running the container now results in a number of errors from WiredTiger suggesting data corruption.  Some of the things we've tried to resolve the issue are running mongod --repair, deleting the mongod lock file, and creating a build of WiredTiger to try to retrieve the data.  The attempt to fetch data with a WiredTiger build resulted in the same errors we saw when using mongo image.
      As well, we have tried changing the versions to 4.2 and 4.0.21 to resolve the versions error.  The error is odd to us because we didn't try to upgrade our version of MongoDB.

      Steps to Reproduce

      Start up the MongoDB container.

      Expected Results

      Mongod --repair results in the database starting up correctly and being able to access data.

      Actual Results

      We receive a set of errors from WiredTiger suggesting data corruption.
