I've have noted something that some of you may find interest in. I have tried fruitlessly to get raid1 working in with Debian woody on a 2.4.18 kernel using raidtools2. I tried countless different means to copy the root filesystem onto the raid filesystem. The best I managed to achieve was about half a file system. All attempts to mount lilo using lilo -r /mnt/md0 device resulted in failure because nodes in the dev directory would never copy onto the mdX filesystem. Out of frustration I updated to the debian testing distro recreated both /dev/md0 and it's filesystem, and all works like a charm. The raidtools versions are both 0.90.200109 for woody and Testing, so the source of the woody woes must lay a little deeper, perhaps the raidtools dependencies weren't as compatible with woody or mke2fs is somehow different. Anyway hope this info helps someone. RE; Unable to mount -- Appologies ! I think the mounting trouble with ... EXT2-fs: md(9.0): couldn't mount because of unsupported optional features (fff80000). cramfs: wrong magic Md: swapper(pid 1) used obsolete MD ioctl, upgrade your software to use new ictls. Kernel Panic. ... was likely fstab pointing to /dev/hda1 with lilo.ocnf root=/dev/md0.
