Abstract
An apparatus comprises a processing device configured to maintain, for a storage system implementing a mapped redundant array of independent disks (RAID) configuration including disk groups providing RAID groups comprising data and hot spare extents, a shared pool of hot spare extents comprising first and second sets of hot spare extents from first and second ones of the disk groups. The processing device is further configured to detect failure of a disk in the first disk group, to determine whether available ones of the first set of hot spare extents provide sufficient storage capacity for rebuilding the failed disk and, responsive to determining that available ones of the first set of hot spare extents do not provide sufficient storage capacity for rebuilding the failed disk, to rebuild the failed disk utilizing one or more of the second set of hot spare extents in the shared pool of hot spare extents.
