Do you have a properly configured /etc/raidtab ?  Are the partitions
supposed to be bootable? If so, did you toggle this in fdisk?
Do you have them in your /etc/fstab set to be mounted at boot time?

I know I've done this countless times, but can't for the life of me
think of anything I've done differently.  It always "just worked".
