In the following lvconvert cmd, the user is requesting a conversion to a 3-way raid and specifies a specific device to be used. Since the raid is already a 3-way raid, the cmd reports that the volume was "successfully converted" even though nothing was actually done. Is there an argument that this should fail or warn since the device requested was not used in a raid conversion?
