title: How to use empty disk spaces under /dev/sdb1 on Azure?
body: <p>I have a VM with 200GB local SSD on Windows Azure. </p>
  
  <p>When I want to use 100GB of it, a "Disk Quote Exceed Error" message is appeared. I can see that my home ( or root) directory is 30GB from the table below ( which is output of <strong><code>df -Th</code></strong> ) </p>
  
  <p>So how can I make the disk space /dev/sdb1 available to use in my home directory?</p>
