2.31. Resizing Volumes

CloudStack does not provide the ability to resize root disks or data disks; the disk size is fixed based on the template used to create the VM. However, the tool VHD Resizer), while not officially supported by Cloud.com or Citrix, might provide a workaround. To increase disk size with VHD Resizer:
  1. Get the VHD from the secondary storage.
  2. Import it into VHD Resizer.
  3. Resize the VHD.
  4. Upload the new VHD.
  5. Create a new VM.
  6. Take a snapshot, then create a new template from that snapshot.
