Abstract
Techniques described herein manage failed storage devices. A number of failed storage devices is determined to exceed a number of redundancies in a storage configuration of the storage system. The status of a failed storage device is changed to permit solely read operations. Valid data from the failed storage device is copied to a spare storage device. Invalid data on the failed storage device is reconstructed based on corresponding data from other storage devices, and the reconstructed data is stored on the spare storage device. The failed storage device is removed from the storage system.
