A system, method and software for enhancing a redundant array of independent disks (RAID) rebuild process are provided. In association with the RAID, one or more bit maps is maintained corresponding to one or more data blocks of the RAID. During input/output (I/O) operations directed to the RAID, the I/O operations are evaluated to determine whether an operation will modify a data block of the RAID. If a data block is to be modified by an I/O operation, the bit map is preferably marked to indicate which data blocks of the RAID are being modified. In the event of disk failure, the bit map may be referenced in association with a disk reconstruction process such that only those data block having been modified before disk failure are reconstructed and these data blocks having not been modified remain substantially free from reconstructive operations.
A method for providing enhanced redundant array of independent disk (RAID) rebuilding, comprising:
Software for facilitating the enhanced rebuilding of a redundant array of independent disks (RAID), the software embodied in computer readable media and when executed operable to direct a computer to:
An information handling system, comprising:
