Good point. Maybe it is better then to die instead of returning so the returned values will not contain a "success".

Return message on a successfull resize is
{"success":1,"data":"UPID:nola:00000B3B:0425A0CD:5F3251DC:resize:300:root at pam:"}

When setting the size to a smaller value, where we die:
{"message":"unable to shrink disk size\n","data":null,"success":0,"status":500}
