If you're willing to re-create (read destroy and remake) the raid, I'd 
suggest http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html

Its what I used to get the raid running of the linux server I have 
here... Works beautifully for some 4? years now.. (but its running 
Gentoo so I don't know how much Fedora specific help I can offer)..

Most "hardware" raid controllers aren't true hardware. Without 
searching, I'd guess you have one of those. The $700 RAID cards (talking 
either SCSI or SATA[2] here) are typically the only ones that have 
hardware raid, true hardware raid, in which case you wouldn't even see 
two separate hard drives being presented... Only one.
