摘要:
A computer implemented method, apparatus, and computer usable program product for managing redundant array of independent drives. In response to a failure of a hard disk in a first RAID array, the process calculates an amount of free capacity available across a set of remaining hard disks in the first RAID array. The set of remaining hard disks comprises every hard disk associated with the first RAID array except the failed disk. In response to a determination that the amount of free capacity is sufficient to re-create the first RAID array at a same RAID level, the process reconstructs the first RAID array using an amount of space in the set of remaining drives utilized by the first RAID array and the free capacity to form a new RAID array without utilizing a spare hard disk.
