F20 -> F21 netinstall raid1 does not find /dev/root

[dwoody5654]

I have done several netinstalls on other computers with no problem.
However, the computer I am having a problem with has raid1.
For the set root entry I have tried:
copied set root from other menu entries
set root='hd0,msdos1'
When the error message no /dev/root drops to dracut I have done
'ls -l /dev/by-label*' and set root = to the uuid

All with no luck in getting past the /dev/root error

Searching for a solution to this problem has found nothing.

What am I missing?

Thanks,

David
