title: Using the Linux Fault Injection framework
body: <p>I'm trying to use the Linux fault injection framework to inject page allocation faults. I'm trying to use the <code>failcmd.sh</code> script provided with the Linux kernel in <code>tools/testing/fault-injection/</code>.</p>
  
  <p>After setting variable <code>FAILCMD_TYPE</code> to <code>fail_page_alloc</code>, I'm running the following command:</p>
  
  <pre><code>./failcmd.sh --times=-1 --interval=1 --verbose=2 &lt;program_to_be_run_with_fi&gt;.
  </code></pre>
  
  <p>All programs I have tried this with have run fine and I do not get any debug information back although I set verbose to 2. I'm using kernel 3.2.0-32 on Ubuntu 12.04.1.</p>
  
  <p>Does anyone have experience with fault injection in Linux?</p>
