A couple months ago, I reinstalled Windows XP Pro and Fedora 8 on my machine which has the Asus M2NBP-VM CSM motherboard featuring NVidia's NForce 430B chipset. I have a primary boot drive that is not a part of the raid but which boots both WinXP and Fedora just fine, and I have a RAID 1 set up with two 100 GB drives, formatted with NTFS.
Now, under Windows I have MediaShield installed and running which allows me to check the RAID status, but Windows has always treated the two drives in the array as a single device even during installation.
Fedora, on the other hand and despite what I've read, is showing the two individual volumes and mounts both automatically. I can read and write to either volume separately, but when I boot into Windows I sometimes lose data because the drives weren't in sync. This is my first experience with a RAID setup, and I'm not sure what I need to do to get Fedora recognizing the RAID properly. I did some searching before this post, and it seems that other people using FC6 were surprised at the fact that Fedora "just worked" and only mounted their arrays as a single volumes.
Did I miss something? Any ideas what I can do to remedy this situation?
Thanks, Raymond

its probably BIOS assisted RAID, aka fakeRAID ... Fedora doesnt support it.

I would rather say it is supported:
% dmraid -l | grep nvidia nvidia : NVidia RAID (S,0,1,10,5)
I even remember FC5 or FC6 had dmraid in installer and allowed install into such fakeraid.
Raymond, I suggest you look into man "dmraid".

Thanks, I'll take a look this afternoon when I'm at the computer again, and I'll let you and everyone else know the results. Raymond

Thanks again for the advice, it appears that dmraid does indeed support my NVRAID/FakeRAID, and I've managed to activate but not mount the NTFS partition on the array. I'll conquer that problem in time. What's troubling me at the moment, is that the two individual drives of the array are being mounted "automagically" by Fedora; they aren't listed in the fstab file at all. A little research is leading me to believe that perhaps the initial installation of Fedora or perhaps an update performed a mkinitrd with those partitions mounted, so they're mounted whenever I boot. I'll have to find a solution to that, and get the raid array entry in /dev/mapper/ mounted via fstab...
Wish me luck... ;) Raymond
