title: Online resize virtual machine disks on Xenserver or Xen
body: <p>I try to increase vitrual disk on running Xen VM.</p>
  
  <p>I use command <code>xe vdi-resize uuid=a68471c4-e4f6-4e8f-9cde-74cba33d67d1 disk-size=13GiB online=true</code></p>
  
  <p>where <code>a68471c4-e4f6-4e8f-9cde-74cba33d67d1</code> is uuid of my xen guest VM.</p>
  
  <p>I try to increase disk size on running VM, but I have a error:</p>
  
  <p>The SR backend does not support the operation (check the SR's allowed operations)
  sr: e062ce43-056b-1044-02af-00fd6c8dc028 (iSCSI virtual disk storage)</p>
  
  <p>I use iSCSI virtual disk storage</p>
  
  <p>What I do wrong?</p>
  
  <p>I use latest Xenserver version/</p>
  
  <p>Has the Xenserver online disk resize feature?</p>
  
  <p>Thanks in advance!</p>
