Intel SW RAID Driver (iswraid) for 2.4 Linux kernels

This driver is for 2.4 series kernels. If you are looking for Intel RAID metadata support in a 2.6 series kernel, it is provided by dmraid. Here is a link to one of the announcements from its author.

If you are looking for a FreeBSD driver supporting Intel RAID metadata, here is a link to it.

Documentation about this driver is included with its releases, in file Documentation/iswraid.txt.

Everything related to this driver is best found from the project summary page. For example, there have been some file releases, the project does use the CVS services where you can find the latest and best released source code and there are discussion forums where no question is considered too dumb (and at the same time an excerpt from the kernel log showing iswraid startup and the contents of /proc/iswraid/* files, if available, are expected).

A few more links to related software and patches:

• LATEST: 2.4.32-iswraid-0-1-6.patch allows using all RAID levels 0/1/5/10 for existing ICH5/6/7.
• The MPB manipulation tool by Axel Reinhold can be useful when manually rebuilding RAID1 volumes that are part of a 2-volume, 2-disk Matrix-RAID setup.
• 2.4.28-pre2-ich6r.patch allows using ICH6R in RAID mode. Not needed with recent 2.4 kernels.
• 2.4.26-rc1-libata3-ich6r.patch enhances the ICH6R support in ata_piix for older kernels/libata. It enables its use in RAID mode with all 4 SATA disks visible and more-or-less independent. Not needed with recent 2.4 kernels.
• 2.4.25-libata5-ich6r.patch does the same thing but works with even older libata. It was noticed that it nicely applies to RHEL3 update 3 kernel and is provided for this reason only. Not needed with recent 2.4 kernels.
