title: Removing the contents of /dev/mapper/vg_ volume when 100%
body: <p>On a CentOS Linux box, when I run the following:</p>
  
  <pre><code>df-h 
  </code></pre>
  
  <p>I get that <code>vg_name-1v_root</code> is at 100%.</p>
  
  <pre><code>Filesystem                      Size  Used Avail Use% Mounted on
  /dev/mapper/vg_name-lv_root     12G   12G     0 100% /
  </code></pre>
  
  <p>When I drill down to <code>/dev/mapper</code> it looks like this <code>vg_name-1v_root</code> is a soft link to <code>../dm-0</code>.</p>
  
  <p>However i'm not able to get into <code>vg_name-1v_root</code> or the <code>../dm-0</code> directories. </p>
  
  <p>I am able to run <code>lsblk</code>, <code>vgs</code> and <code>lvs</code> to view the volume, but cannot enter it or view the contents. </p>
  
  <p>I've spent some time googling and searching Stack Overflow. How can I delete or even view what's in the directory <code>/dev/mapper/vg_name-1v_root</code>?</p>
  
  <p>Many thanks in advance.</p>
