Batch Rebuilding a Set of Encoded Data Slices

Abstract:

A method includes, determining, for a batch rebuild process regarding a first batch threshold number of encoded data slices of a set of encoded data slices that need rebuilding, a target storage unit of target storage units of a set of storage units of the storage network is unavailable, where a data segment of data is dispersed storage error encoded into the set of encoded data slices, the set of encoded data slices is stored in the set of storage units, and the first batch threshold number of encoded data slices is to be stored in the target storage units. When the target storage unit becomes available before a second batch rebuild threshold number of encoded data slices of the set of encoded data slices is met, the method includes executing the batch rebuild process for the first batch threshold number of encoded data slices.
