Abstract
Methods and systems for rebuilding a failed storage device in a data storage system. For example, a method including identifying a first garbage collection group (GCG) in a storage array for garbage collection; extracting valid data and redundancy information from functioning storage devices in the storage array associated with the first GCG; reconstructing data of a failed storage device associated with the first GCG based on the extracted valid data and redundancy information from the functioning storage devices associated with the first GCG; consolidating the extracted valid data from the functioning storage devices and the reconstructed data of the failed storage device associated with the first GCG; writing the consolidated extracted valid data from the functioning storage devices and the reconstructed data of the failed storage device associated with the first GCG to a second GCG in the storage array; and reclaiming the first GCG identified for garbage collection.
