Is there some reason why a RAID 1 set built under 2.6.5 would not work under 2.4.22? I build a machine (Slackware) with two RAID 1 mirrored drives under a 2.6.5 kernel. I later discovered that I needed to drop back to a 2.4.22 kernel in order to do some clustering under openMosix and TKCluster so I downloaded the recommended TKCluster 2.4.22 kernel. This kernel is a standard kernel with patches for libata and openMosix. I rebuilt the kernel including support for RAID and serial ATA (ICH5). When I boot the 2.4.22 kernel it goes along nicely until it tries to mount the root partition. It then throws up a "modprobe" error. Something about char-major 9 I think? (I'm sorry but I am not near the console at the moment). Is there some reason why a RAID 1 set built under 2.6.5 would not work under 2.4.22? Is there something I've forgot to include in my 2.4.22 kernel that is preventing it from mounting?
