Identifying a slice error in a dispersed storage network

摘要

A method begins by a dispersed storage (DS) processing module identifying a set of collections of records corresponding to a data segment that is stored in a dispersed storage network (DSN) as a set of encoded data slices, wherein a collection of records includes an event record including information regarding an event, a first record including information regarding a dispersed storage (DS) processing module processing an event request to produce a plurality of sub-event requests, and a plurality of records including information regarding a set of DS units processing the plurality of sub-event requests. The method continues with the DS processing module determining whether an error exists for one of the set of encoded data slices based on at least some of the set of collections of records and when the error exists, flagging the one of the set of encoded data slices for potential rebuilding.

1. A method for correcting a storage error within a dispersed storage network (DSN), the method comprises:
identifying a set of collections of records corresponding to a data segment that is stored in the DSN as a set of encoded data slices, wherein a collection of records of the set of collections of records includes:
an event record including information regarding an event, wherein the event is a user access operation or a system administrative operation initiated by a device affiliated with the DSN;a first record including information regarding a dispersed storage (DS) processing module processing an event request to produce a plurality of sub-event requests, wherein the event request is regarding the event; anda plurality of records including information regarding a set of DS units processing the plurality of sub-event requests; determining whether an error exists for one of the set of encoded data slices based on at least some of the set of collections of records; and when the error exists, flagging the one of the set of encoded data slices for potential rebuilding.
