Hi folks,

does anyone know an (virtual) block device which can do automatic
defect management (if the underlying disks have badblocks) ?

My idea goes like this: 
* one or more devices are assigned to one block device
* a bunch of spare blocks are reserved for defect management 
  (so the device looks smaller than the sum of assigned disks)
* if an badblock is detected, it's automatically remapped 
  to an spare block
  
In fact, just what drive-internal defect manangement does, but
at OS / driver level.
