Software RAID + LVM2

In your NFSROOT, or rather at the time of running setup-storage, do you have
either /etc/mdadm/mdadm.conf or /etc/mdadm.conf? I just checked the contents of
mdadm-startall, which seems to use those files if available. If this is not the
case for you, it will be creating such a file - which presumably we also could
do within setup-storage. 

Thanks a lot,
Michael
