I'm sorry for my late response, I'm just back to work today from 
vacation. In the past months, I learned and worked for cluster-md feature,
and I have draft one test suit for cluster-md feature. please refer to 
https://github.com/zhilongliu/clustermd-autotest
I'm very willing to do something for improving mdadm testing part, also 
wanna improve cluster-md test suit, welcome all comments for it.
