      Hello,

      My mongodb likely had an unclean shutdown and i have spent days trying to get it back up. I am able to start a new mongodb instance in a new location but cannot get my old one with all of my old collections and indexes to work properly. When I try to repair it, it gives the following message:

      From past people experiencing the same issues, it would appear my WiredTiger.rt is corrupted? Can anyone please assist with these issues? I have attached my associated WiredTiger.rt files.
