This is my config file:

raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4
persistent-superblock 1
device /dev/hda
raid-disk 0
device /dev/hdb
raid-disk 1

Any ideas why it didn't work? I also has issues with mdadm, I'm using fedora core 2

What does this produce in /var/log/messages? What are the contents or /proc/mdstat?
