Subject: [gentoo-user] defect management block device
Date: Mon, 24 Mar 2008 15:32:45 +0100	[thread overview]
Message-ID: <20080324143245.GC10053@nibiru.local> (raw)


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.
