Abstract
Methods, systems, and other aspects for reconstructing data and rebuilding a failed storage device in a storage system using one or more functioning compute resources and/or storage resources of the failed storage device. For example, a method may include, responsive to a detection of a failed storage device in a storage system, locating data and redundancy information in functioning storage device(s) in the storage system for reconstructing data of the failed storage device; issuing peer-to-peer commands to the functioning storage device(s) to obtain the data and the redundancy information from the functioning storage device(s); and reconstructing the data of the failed storage device based on the data and the redundancy information obtained from the functioning storage device(s), wherein a functioning compute resource of the failed computing device at least partially performs one or more of the locating, issuing, and reconstructing.
