    摘要： A method for execution by a computing device of a storage network begins by receiving a write request for a data object, determining a plurality of data regions for the data object, determining storage identification information for each data region of the plurality of data regions and generating a storage table for the data object that includes information sufficient to identify each data region of the plurality of data regions. For a first data region of the plurality of data regions the method continues by dividing the first data region into a plurality of data segments, and dispersed error encoding the plurality of data segments to produce a plurality of sets of encoded data slices. The method then continues by sending a write request for each encoded data slice of each set of encoded data slices of the plurality of sets of encoded data slices to the storage network, and when at least a write threshold number of write responses is received for each of the plurality of sets of encoded data slices the method ends by updating the storage table to indicate that the first data region is available for retrieval.

    摘要： Event records from multiple computing devices are received at a managing unit. Individual event records include an event identifier field including an event identifier identifying a first event associated with a particular computing device, a parent event identifier field identifying a parent event that initialized the first event, and an entity identifier field including an entity identifier identifying the particular computing device. The managing unit generates log records associated with event identifiers included in the event records. The log records include state fields indicating a state of a particular event associated with a particular event identifier. Based on a correlation of the event and log records, the managing unit determines at least two computing devices associated with events resulting in an error state, and identifies parent events that initialized the events with errors. The managing unit generates a report linking the parent events to the events having an error state.

    摘要： A processing system of a storage network operates by: sending, to at least one storage unit of the storage network, at least one read request corresponding to at least a read threshold number of a set of encoded data slices to be retrieved, wherein the set of encoded data slices correspond to a data segment, wherein the data segment is coded in accordance with dispersed error coding parameters that include a write threshold number and the read threshold number, wherein the write threshold number is a number of encoded data slices in the set of encoded data slices and wherein the read threshold number is a number of the set of slices that is required to decode the data segment; receiving, via the at least one processing circuit and from the at least one storage unit, a first subset of encoded data slices of the set of encoded data slices, wherein the first subset of encoded data slices is missing at least one missing encoded data slice that was not received from the at least one storage unit in response to the at least one read request and wherein the number of encoded data slices in the first subset of the encoded data slices is less than the read threshold number; generating, via the at least one processing circuit, at least one rebuilt encoded data slice corresponding to the at least one missing encoded data slice utilizing locally decodable redundancy data, wherein the locally decodable redundancy data generated from a second subset of the set of encoded data slices that includes the at least one missing encoded data slice; and recovering, via the at least one processing circuit, the data segment based on the at least one rebuilt encoded data slice and the first subset of encoded data slices.
