Abstract
Technology for relocating data stored in an end of life source storage drive that identifies individual destination drive extents corresponding to drive extents located in the source storage drive by selecting individual storage drives within a set of healthy storage drives in a group of storage drives in a round robin manner and identifying an individual destination drive extent from each selected storage drive. The corresponding destination drive extents replace the drive extents located in the source storage drive, and are used to store data copied from the drive extents located in the source storage drive. Data is copied in parallel from a set of multiple drive extents located in the source storage drive that is selected based on the current total input/output load determined for each storage drive in the set of healthy storage drives, and on the storage drives on which the corresponding destination drive extents are located.
