    Abstract: A method begins a first rebuilder application identifying a data slice having a storage error. The method continues with the first rebuilder application or a second rebuilder application identifying a data segment based on the identified data slice. The method continues with the second rebuilder application identifying one or more other slice servers that are storing other data slices of the encoded data segment. The method continues with the second rebuilder application receiving a sufficient number of the other data slices to reconstruct the data segment and decoding them to reconstruct the data segment. The method continues with the second rebuilder application encoding the reconstructed data segment in accordance with the information dispersal algorithm to produce a new set of data slices and selecting one of them as the rebuild data slice.
