    Move a Nvidia RAID0 from Windows to Kubuntu

    Friend of mine has a computer that is running an 'nvidia' raid from an Asus motherboard. I am in the process of planning out a move for him to Kubuntu.

    Anyone think of any "gotchas" or dangers that might happen with this? I do believe that he has two 2 Tb drives. So it's not NTFS, it's that "larger than something" file system in Winders.

    Can't comment on the nVidia thing, I've never used one.

    Are you sure the existing file system isn't NTFS? FAT32's maximum is 2 TB if the sector size is 512 bytes, or 16 TB if the sector size is 4096 bytes -- but this second method isn't very common.

      I did not know Nvidia makes a RAID controller -- you'd better double-verify that theory.

      Then, if that checks out, you need to learn whether Linux supports that RAID controller with a hardware driver. If not, the RAID won't transfer.

      Of course, a software RAID would be possible (fakeraid, dmraid -- google will help). But that makes the CPU do all the work -- performance on other tasks will be compromised accordingly.

      However, if it were me, after a 100% data backup, I'd install a btrfs filesystem, spanning both of the drives, using default settings for a multi-drive filesystem. It provides mirroring of metadata, and striping of raw data -- I've been running just such a btrfs filesystem on a pair of WD1002 drives for over 1 year now, with zero problems.

        I need to research the motherboard, but I'm sure that it's a Nvidia "fake raid" I'm sure that it isn't a full blown raid controller. But I seem to remember him saying it was a NVIDIA nForce 980a SLI northbridge chipset.

        According to Win7, it's a "NVIDIA nForce RAID Controller".

        Might just back it all up and make a LVM and forget the raid.

          My last clean install on my PC was 11.04 to an nvidia RAID1 array.
          No issues at all, although the previous couple of releases would not see the array.

          Just boot the disc and go through the install process.
          It will show the array in the disc partitioning section of the install if it can use it.

          If it isn't recognised then it won't present any drives to install to.
          You don't need a license to drive a sandwich.

            If it's not NTFS, then it's FAT32, so whatever you do to the computer will be better than what it has now. This includes throwing it in the trash and setting it on fire.

              Do you mean it is a UEFI booting motherboard? That's not the filesystem, that's the replacement for the traditional BIOS. GPT is the replacement for the MBR partition table, but AFAIK BIOS/MBR can boot disks up to 2.2 GB, so this should not be a problem for a pair of 2TB drives. You might want to study up on how GPT works -- I have not yet had the opportunity to play with it. You might have to use gdisk to do the partitioning.

                AFAIK ntfs will support a 2TB file system on a MBR disk but up to 16EB on a GPT disk so it can still be ntfs.

                IMO hardware based raid has inherent dangers that linux software raid does not - mostly that you're slaved to a particular chipset. If your mobo fails - goodbye raid. If you're keeping windows, you'll have to either give up the raid or partition the drives if you want to use linux software raid.

                Either way you go - take some time to plan it out thoughtfully and backup anything you don't want gone!
