                          I believe my MongoDB did not have a clean shutdown. I am able to restart it in a new location which doesn't have all of my collections. If I try to repair or start it in the old location, it gives the following error:

    [ec2-user@ip-172-31-30-192 tmp]$ mongod --repair --dbpath /data

Is there a way to fix my wiredtiger.wt file or move my collections and indexes from the old location into the new location?
