Abstract
A method includes generating integrity data of one or more slice names of one or more error encoded data slices and evaluating the integrity data, without using any of the error encoded data slices, for an inconsistency between the plurality of received integrity data. The method further includes indicating an error based on the evaluating the integrity data indicating an inconsistency, retrieving one or more slice names for the one or more error encoded data slices, and when detecting that at least one data error has occurred at a plurality of storage units at a DSN site/pillar, determine that a DSN site/pillar failure has occurred and after a predetermined time period, if the DSN site/pillar failure has not been resolved, rebuild the error encoded data slices of the DSN site/pillar and store them at another DSN site/storage unit.
