I enabled the RAID feature in my nVidia NF4 BIOS.
When I booted Fedora 9, it located my RAID array and saw it as /dev/mapper/nvidia_ehedchbe
I created the partitions which were labeled as above but with ...p1 /boot, p2 swap, p3 /
The install went OK until I rebooted. Grub went to boot the kernel and there was a kernel panic. libnash crashed... reading around the net, I saw that people said go with linux software raid, because the nVidia nForce4 raid controller is half hardware, and half software so it's not 'real' raid. I also read that Linux's software raid was faster than the nVidia raid.
In any case, has anyone gotten linux to boot off of /dev/mapper/nvidia_***** with the sata_nv driver? Should I go with linux anyways in case of a mobo failure, I can easily swap the drives out into another mobo with linux immediately being able to resolve the issue (i.e.: I won't be stuck having to have to get another nVidia raid mobo)? And... Is it really "Software" RAID even though I configure the RAID array in the RAID bios?
The link below was what I was going to do three years ago and just now got around to it. This is what I have just done (for testing) and I'll find out if linux can boot off of /dev/md0 (with nodmraid kernel option):
