    Description

      I'm not able to access my mongo db with the following error in the logs. The disk space on the server became full and now Mongo won't allow connections and the service runs only for a short time before stopping. The disk space has been cleared but I have been reading around and it could be the wiredtiger files have been corrupted.

      I have attached these. Are they able to be repaired?
