Default PCBSD doesn't see my RAID array
I am trying to install PCBSD on my Shuttle SN25P which has an Nvidia Nforce4 motherboard with onboard RAID. When I get to the drive screen I see my mirrored hard drives listed individually rather than as a single drive.

The regular FreeBSD 6.0 installer shows the RAID array correctly.

Any ideas what is happening here?

What raid controller is this?

I have a mobo that has this chipset, I have the same problem, you will probably won't be able to use your drives in Raid unless you buy a hardware Raid controller (rather than software controller) compatible with FreeBSD :roll:

RAID controller is the one on NVidia Nforce4 Ultra motherboard that comes with Shuttle SN25P - http://www.nvidia.com//page/nforce4.html

Do you think if I allow PCBSD to write to one of the drives that it can see, the RAID hardware will do the mirroring to the other drive anyway? Or am I going to screw up my other partitions if I even attempt this?

Not about to disrupt my current main OS (or shell out for extra hardware) in order to test out PCBSD.

If it shows two different drives, then it works just like standard ide controller, not like raid. You can use FreeBSD software raid features(vinum) of course.

I thought that hardware RAID would hide the drives completely from BSD exposing only the array. Now it seems these NVidia onboard RAID's aren't real hardware RAID, but some sort of software (albeit on a chip). Anyway, puzzled that FreeBSD 6.0 install would allow me to use the RAID array, whilst PCBSD does not. Was this intentionally removed?

Maybe some raid controller device is missing in PC-BSD kernel config- have to add it then.

Someone on the Gentoo forum told me it was a dmraid driver that was required. Wonder if this is the same for BSD?

When you say "have to add it then" do you mean I have to add it (in which case how would I go about that) or do you mean that PCBSD developers will have to add it (in which case, how likely is that to happen, and any idea of timescale?)

Cheers,
