title: MongoD doesn't stop on CentOS
body: <p>I try to shutdown mongoD in order to make a backup. However when I send <code>service mongod stop</code> it totally failed <code>Stopping mongod:[FAILED]</code></p>
  
  <p>I took a look on mongodb logs and there is nothing about shutdown...</p>
  
  <p>I've got important data on this DB and i don't want to kill anything, so as i'm a beginner in mongoDB, I prefer to ask here what to do before destroy everything. </p>
  
  <p>I was thinking about kill the process of MongoD, make my backup with mongodump and restart MongoD, but i'm not sure that it will work.</p>
  
  <p>Thanks for helping. </p>
