摘要： A method begins by a processing module receiving a file retrieval request for a file, wherein the file includes one or more data regions, and wherein a data region of the one or more data regions is divided into a plurality of data segments and stored as a plurality of sets of encoded data slices in a dispersed storage network (DSN) memory. The method continues with the processing module retrieving a segment allocation table (SAT), wherein a SAT entry of a plurality of SAT entries includes information regarding storing the data region in the DSN memory and a segmentation scheme regarding the dividing of the data region into the plurality of data segments. The method continues with the processing module identifying the plurality of sets of encoded data slices and retrieving at least a sufficient number of the plurality of sets of encoded data slices to regenerate the data region.

摘要： A method begins by a dispersed storage (DS) processing module of a DS unit selecting a data slice for corruption analysis and requesting integrity information for the data slice from one or more other DS units of a dispersed storage network. When the one or more requested integrity information is received, the method continues with the DS processing module analyzing the one or more received integrity information and local integrity information of the data slice stored in the DS unit. When the analysis of the one or more received integrity information and the local integrity information of the data slice is unfavorable, the method continues with the DS processing module identifying the data slice as being corrupted.
