I have defined several raid-1 arrays using both mdadm and raidtools, and in all cases it works fine until I reboot the machine. I expected Knoppix to autodetect the raid array and assemble it, but it never does. Mdadm shows the partitions as being part of some unknown array, so information is being kept around, but it is not used.

I must be missing something very simple. Could anyone give me a pointer?

Thanks very much.
