Is /etc/mdadm.conf up to date?  Run "mdadm --detail --scan" to get the 
information you need, and either replace the lines in mdadm.conf or add 
the one that's missing.  You might need to rebuild the initrd afterward 
(dracut --force).  I'm unclear on why any of that would be necessary, 
though.  I don't usually add pre-existing arrays to running systems, so 
I'm a bit out of my experience here.
