Although the instructions work, there are pitfalls when one of the disk fails.

I sought help in this mailing list way back in June/July 2012 time
frame.   I would suggest you search the list archives of that period.

I did update dracut to the latest version but removing and restoring a
failed disk would not boot.

Posted the problem in the madm mailing list as well with no resolution.

See below.

I second the above option, if you have the luxury.  In the "other"
method, the system at least boots with one disk gone.
