摘要： A method begins by a processing module receiving an encoded data slice to store and determining a slice length of the encoded data slice. The method continues with the processing module comparing the slice length to a plurality of bin widths, wherein each of the plurality of bin widths represents a fixed storage width of a plurality of memory bins within each of a plurality of memory containers, wherein a storage unit includes the plurality of memory containers. The method continues with the processing module selecting one of the plurality of memory containers based on the comparing to produce a selected memory container, identifying an available bin of the plurality of bins of the selected memory container, and storing the encoded data slice in the available bin.

摘要： A method begins by a dispersed storage (DS) processing module receiving a request to copy a data object in a dispersed storage network (DSN). The method continues with the DS processing module identifying one or more sets of at least a decode threshold number of slice names for one or more sets of encoded data slices of the data object and generating one or more sets of at least a decode threshold of new slice names. The method continues with the DS processing module sending the one or more sets of at least a decode threshold of new slice names to storage nodes of the DSN and instructing the storage nodes to link the one or more sets of at least a decode threshold of new slice names to the one or more sets of encoded data slices thereby producing a non-replicated copy of the data object.

摘要： A method begins by a processing module decoding a set of encoded data slices to produce a decoded data segment and determining whether the decoded data segment includes an error. When the decoded data segments includes the error, the processing module identifies one or more errant encoded data slices by decoding another set of encoded data slices to produce another decoded data segment. The method continues with the processing module determining whether the other decoded data segment includes the error. When the other decoded data segment does not include the error, the processing module identifies the one or more errant encoded data slices and corrects the one or more errant encoded data slices. When the other decoded data segment includes the error, the processing module repeats, for yet another set of encoded data slices, the decoding step, the determining step, and the identifying and correcting step or the repeating steps.
