  abstract = {We present the design, implementation, and evaluation of D-GRAID,
  a gracefully-degrading and quickly-recovering RAID storage array. D-GRAID
  ensures that most files within the file system remain available even when an
  unexpectedly high number of faults occur. D-GRAID also recovers from failures
  quickly, restoring only live file system data to a hot spare. Both graceful
  degradation and live-block recovery are implemented in a prototype SCSI-based
  storage system underneath unmodified file systems, demonstrating that
  powerful "file-system like" functionality can be implemented behind a narrow
  block-based interface.},
