We need fallback here - since if the user doesn't have dm-raid -  then he 
needs to manually configure defaults.

As a result automated tests on systems without dm raid fails.

Also we need to update all tests which were supposed to test mirrors,
to really test mirrors - otherwise we are checking raid code twice
(and even without checking  dm-raid version presence)
