I have migrated my Debian -unstable system to raid1 handled by madm as directed in http://xtronics.com/reference/SATA-RAID-debian-for%202.6.html. I use Linux 2.6.9, / is on md2, /boot on md0 and swap on md1. I use mdadm 1.7.0 (the one shipped with Debian). At boot time, the kernel correctly boots from md2 but init fails to mount md0 as /boot and setup the swap space on md1 as those devices do not exist. If I create them by hand with "cd /dev && ./MAKEDEV md" when I get a root shell for maintenance and start them using "mdadm -A -s", I can continue the boot process manually. The partition types are set to 0xfd, /proc/mdstat reports: Personalities : [raid1] md0 : active raid1 sda1[0] sdb1[1] 192640 blocks [2/2] [UU] md1 : active raid1 sda5[0] sdb5[1] 1951744 blocks [2/2] [UU] md2 : active raid1 sda6[0] sdb6[1] 37110016 blocks [2/2] [UU] unused devices: As far as I can tell, the "mdadm-raid" script which does "mdadm -A -s" is present as /etc/rcS.d/S25mdadm-raid which is a right place as it will be run before mounting other file systems. However, the absence of /dev/md0 and /dev/md1 prevent the raid arrays from being started. What can I do to ensure that /dev/md0 and /dev/md1 exist when the script is run?
