Apparatuses and methods and computer program products for a redundant array of independent disk (raid) reconstruction

A non-transitory computer program product for a redundant array of independent disk (RAID) reconstruction when executed by a processing unit coupled to a RAID group comprising a plurality of drives, the computer program product comprising program code to:

• start an unused-space scan procedure to determine a logical address range that is a candidate to be skipped for the RAID group and send the logical address range to a stripe reconstruction procedure;
• and
• start the stripe reconstruction procedure to receive the logical address range from the unused-space scan procedure, determine a stripe of the drives to be skipped from being reconstructed according to the logical address range, and omit a reconstruction to the determined strip.
