Abstract:
1. A method for rebuilding an encoded data slice for a maintenance free storage container, the method comprises: detecting a storage error of the encoded data slice associated with a storage server of a plurality of storage servers within the maintenance free storage container, wherein the maintenance free storage container allows for multiple storage servers of the plurality of storage servers to be in a failure mode without replacement, wherein data is encoded using a dispersed storage error coding function to produce a set of encoded data slices, which includes the encoded data slice, and wherein at least some encoded data slices of the set of encoded data slices are stored in other storage servers of the plurality of storage servers; determining failure mode information for the storage server and the other storage servers; determining a rebuilding protocol for the encoded data slice based on the failure mode information and whether at least a decode threshold of the other storage servers are available; when the determined rebuilding protocol is a zero information gain (ZIG) protocol:
