Marcus Sorensen closed CLOUDSTACK-1445.
---------------------------------------
Resolution: Won't Fix
QCOW2 doesn't allow shrink, per qemu-img resize. Therefore the code checks to
see if you're trying to shrink a QCOW2, and returns a proper error.
> Resize volume[Data Disk] failed when shrink volume is set to true [20 GB to
> 10 GB]

> } else if (type.equals("QCOW2") && shrinkOk) {
> return new ResizeVolumeAnswer(cmd, false, "Unable to shrink volumes of
> type " + type); }
> Seems like a logical mistake? Shouldn't that be !shrinkOk?
