1. A method for execution by a processing module of one or more computing devices, the method comprises:

  • 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);

    identifying the encoded data slice for rebuilding;

    identifying one or more storage traits associated with the encoded data slice;

    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;

    prioritizing, within the rebuilding process, 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.
