From http://unthought.net/Software-RAID.HOWTO/Software-RAID.HOWTO-4.html#ss4.10
--------------------------------------------- 4.10 Autodetection
Autodetection allows the RAID devices to be automatically recognized by the kernel at boot-time, right after the ordinary partition detection is done.
This requires several things: * You need autodetection support in the kernel. Check this * You must have created the RAID devices using persistent-superblock * The partition-types of the devices used in the RAID must be set to 0xFD (use fdisk and set the type to ``fd'') ---------------------------------------------
I guess you forgot to mark the partitions as type 0xfd. I have a similar box here with 2.4.1 and autodetect works like a charm.
