What version of fedora?  What kind of raid? raid0, raid1, raid5?  Are you 
using strictly software raid?  I.e, not a true hardware raid controller? 
What is in your /etc/mdadm.conf?

I have seen problems when mkinitrd did not include the proper kernel modules 
in the initrd.  If your system is up-to-date, then that should not be the 
problem.  Also, I have had problems with multipath and always use the kernel 
parm "nompath" when doing a Fedora install since anaconda seems to be 
confused by bios' with so-called raid controllers that are being used in ide 
only format.

Currently, I am having issues with a rawhide installation and software raid 
since the raidsets are no longer started by sysinit, but are supposedly 
started by udev.  I have to do a manual mdadm --assemble /dev/mdX --scan to 
get some of the arrays going.

There doesn't seem to be a lot of love in Fedora land for raid probs, but 
then, it just may be me.
