title: MISCONF Redis is configured to save RDB snapshots
body: <p>During writes to Redis ( <code>SET foo bar</code> ) I am getting the following error:</p>
  
  <blockquote>
    <p>MISCONF Redis is configured to save RDB snapshots, but is currently
    not able to persist on disk. Commands that may modify the data set are
    disabled. Please check Redis logs for details about the error.</p>
  </blockquote>
  
  <p>Basically I understand that the problem is that redis is not able to save data on the disk, but have no idea how to get rid of the problem.</p>
  
  <p>Also <a href="https://stackoverflow.com/questions/16472786/configuring-redis-to-play-nice-with-appharbor">the following question</a> has the same problem, it is abandoned long time ago with no answers and most probably no attempts to solve the problem.</p>
