dmraid will alert you if the RAID set becomes incomplete or
experiences an error.

smartd will alert you if the disks themselves experience errors (even
ones that are remapped by the drive, in my experience).

I don't know if there's any sort of functionality like the drive
scrubbing that 3ware cards have.  (They periodically read, reconstruct
if necessary and rewrite all of the sectors on all of the drives,
which prevents sectors from going bad silently.)  You can run a cron
job that asks the drives in your RAID set to do online self fests;
smartd may even support doing that automatically.
