----------------------------------------

             Summary: UI should show error message user tries to shrink the VM ROOT volume size
                 Key: CLOUDSTACK-9697
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9697
             Project: CloudStack
          Issue Type: Improvement
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: UI
    Affects Versions: 4.9.0, 4.8.0, 4.7.0
            Reporter: Rashmi Dixit
            Assignee: Rashmi Dixit
             Fix For: 4.9.1.0


If a user tries to shrink the size of the root volume of a VM, the operation fails with an error 
Going from existing size of 10737418240 to size of 8589934592 would shrink the volume.Need to sign off by supplying the shrinkok parameter with value of true.

Instead, the UI can simply not allow shrink operation on the ROOT volume. Throw a more user friendly message
"Shrink operation on ROOT volume not supported"
