Sound like a bug.

You can kill the process started by this task - since 3.6 this we use only
qemu-img, before that we use also dd for copying volumes.

Killing the underlying process doing the copy is safe, the operation should
fail and engine will delete the halfy-copied volumes.

Adding vdsm logs from the time you started the task will help to understand
why aborting and clearing the task did not work.
