Abstract
A method begins by a dispersed storage (DS) processing module detecting, in accordance with a rebuilding process, a storage error of an encoded data slice stored in a storage node of a dispersed storage network (DSN) and identifying the encoded data slice for rebuilding. The method continues with the DS processing module identifying one or more storage traits associated with the encoded data slice and identifying encoded data slices having at least one storage trait in common with the one or more storage traits of the encoded data slice to produce identified encoded data slices. The method continues with the DS processing module prioritizing storage error detection analysis of the identified encoded data slices over other encoded data slices stored in the DSN and when a storage error is detected for one of the identified encoded data slices, identifying the one of the identified encoded data slices for rebuilding.
