    摘要: A method begins by identifying a data slice requiring rebuilding to produce an identified data slice, wherein the identified data slice is one of a plurality of data slices that constitute a data segment and wherein each of the plurality of data slices is assigned for storage by a corresponding one of a plurality of data slice servers. The method continues by retrieving at least m number of data slices from at least m number of the plurality of data slice servers, wherein m data slices of the plurality of data slices enable reconstruction of the data segment, and wherein the at least m number of data slices does not include the identified data slice. The method continues by reconstructing the identified data slice from the at least m number of data slices to produce a rebuilt data slice. The method continues by writing the rebuilt data slice to the corresponding one of the plurality of data slice servers or to a new slice server.

    摘要: An apparatus includes a processing module and a network interface. The processing module is operably coupled to obtain; a data storage transaction request regarding a file; determine identity of a user based on the data storage transaction request; access file level metadata based on the identity of the user to determine a plurality of file slices associated with the file; access file slice metadata to identify at least one of a plurality of storage nodes that stores or is to store, a data slice and coded subsets of at least one of the plurality of file slices; and generate a data storage transaction message to facilitate a data storage transaction regarding the at least one of the plurality of file slices. The network interface is operably coupled to convert the data storage transaction message into a network data storage message and transmit it.
