How to get my NTFS RAID volume seen through linux


Hi all,

I have 2x RAID 0 (meaning 4 HDD connected to 2 different controllers on the MB)

I would like Linux to be able to install on the RAID volume.
What parameters do i have to type to get the partition seen.

Using either SuSE or Mandrake 9.2.
(have the drivers for the fastrak for linux)

Thanks

Sure, I'll take a stab at it

I don't have a lot of experience with RAID, but I've managed to get my kernel to recognize a RAID card and let me have read-write access to my NTFS partitions. Here's what I know:

You'll need to compile into the kernel the drivers for multi-device support. Go into your kernel source directory (if you don't have kernel source, you'll have to download it from www.kernel.org) and type, as root, "make gconfig" (this requires you to be running in an X windows environment). Now go to "options (menu) > show all options". Then scroll down to "Device Drivers" and go to "Device Drivers > Multi-Device Support (RAID and LVM)" and double-click "Multiple Devices Driver Support" and "RAID Support" until there are check marks in both boxes. Now expand the "RAID Support" option and make sure that your desired RAID configurations/options are check-marked or loaded as modules (a line in the box).

This should work, but you might want to enable some SCSI support just in case the kernel wants to think of your RAID controller as a SCSI device.

Back up your kernel, recompile it, make sure LILO/GRUB can see the new kernel, and reboot.

Your RAID filesystems should now be listed in /dev/hdxx or /dev/sdxx. Mine is /dev/hde1 (since it's not build-into my motherboard). Yours might be /dev/hda1, /dev/sda1 (for SCSI devices), etc.

Good luck!

P. S. You can get drivers that will allow you to have read-write access to NTFS partitions at http://www.jankratochvil.net/project/captive/ . The program is called "captive-ntfs", and currently uses LUFS, which I believe comes with it. The only catch is that you'll have to have "cdfs.sys", "ext2fsd.sys", "fastfat.sys", "ntfs.sys", and "ntoskrnl.exe" from a NTFS-compatible WIndows installation in order to run it. Of course, if you didn't have an NTFS Windows installation why would you be using NTFS? :-D You may need to upgrade to the latest kernel (2.6.8 last I checked) in order to use it. I hope this helps. Have a good one.
