Abstract
A method includes retrieving a read threshold number of integrity check value list (ICVL) encoded data slices of a set of ICVL encoded data slices. The method further includes determining whether an appended ICVL of each ICVL encoded data slice of the read threshold number of ICVL encoded data slices substantially match. When the appended ICVL of one of the ICVL encoded does not substantially match the appended ICVL of other ICVL encoded data slices, the method further includes determining a likely cause for the mismatch. When the likely cause is missing a revision update, the method further includes initiate rebuilding of the encoded data slice portion. The method further includes generating an integrity check value for the rebuilt encoded data slice and updating the integrity check value list. The method further includes appending the updated integrity check value list to the rebuilt encoded data slice.
