I've encountered some hairy problems attempting to boot into a raid1 root filesystem. The boot fails with unable to mount. The trouble starts 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. I'm using a straight debian woody with 2.4.18 all raid options compiled into the kernel. I use mkraid to create the md0 device with the following raidtab... ## Test RaidTab raiddev /dev/md0 raid-level 1 nr-raid-disks 2 chunk-size 16 # Spare disks for hot reconstruction nr-spare-disks 0 persistent-superblock 1 device /dev/sda1 raid-disk 0 # pseudo failed disk current root part device /dev/hda1 failed-disk 1 Should I be using mdadm instead of mkraid, or are the Debian woody raidtools too old, too new??? I'm using Raidtools2 version 0.90.200109. Any help greatly appreciated!
