Abstract

See full text

A method begins with a processing module storing a set of encoded data slices in memory of a dispersed storage network (DSN), where a data segment is encoded using an error coding dispersal storage function to produce the set of encoded data slices. The method continues with the processing module adding the data segment to a rebuilding list, where encoded data slices of data segments identified in the rebuilding list are checked via a rebuilding process to detect errors and, when one of the encoded data slices has an error, the rebuilding process rebuilds the one of the encoded data slices. The method continues with the processing module, in response to a condition, removing the data segment from the rebuilding list.
