Dispersed storage re-dispersion method based on a failure

摘要

A method begins by identifying a storage unit of a set of storage units within a dispersed storage system as being likely to fail. The method continues by determining an approach for minimizing rebuilding the encoded data slices that are stored on an identified storage unit in an event of a failure of the identified storage unit. The approach is at least one approach option from a list of approach options that includes fostering new encoded data slices, replicating existing encoded data slices, and re-dispersing existing encoded data slices. The method continues by implementing the approach regarding the identified storage unit and when the identified storage unit fails, retrieving the encoded data slices that were stored on the identified storage unit based on the approach.

1. A method for execution by a computing device, the method comprises:
identifying a storage unit of a set of storage units within a dispersed storage system as being likely to fail; determining an approach for minimizing rebuilding of encoded data slices stored on the identified storage unit in an event of a failure of the identified storage unit, wherein the approach is at least one approach option from a list of approach options, wherein the list of approach options includes fostering new encoded data slices, replicating existing encoded data slices, and re-dispersing existing encoded data slices; implementing the approach regarding the identified storage unit; and when the identified storage unit fails, retrieving the encoded data slices that were stored on the identified storage unit based on the approach.
