title: Mongo shell not showing databases?
body: <p>I have various Mongo databases and when I do <code>ls -l</code> in my CentOS linux I can see the databaseA.0 and databaseA.ns files for each database and the file size is large enough to tell my data is still there, but when I go to the mongoDB shell by executing the <code>mongo</code> command and do a <code>show dbs</code> or <code>show databases</code> it only shows admin(empty), local 0.078GB, and test(empty).
  How do I get my databases back?</p>
  
  <p>Additonal info:
  When I start the mongo shell I get the following:</p>
  
  <pre><code>MongoDB shell version: 2.6.4
  connecting to: test
