STORING RAID DATA AS ENCODED DATA SLICES IN A DISPERSED STORAGE NETWORK

摘要

A method includes determining whether at least a portion of a data object requires rebuilding, wherein the data object is stored in accordance with a RAID formant. The method further includes, when the at least a portion of the data object requires rebuilding, reconstructing stripes from sets of data blocks and parity blocks. The method further includes dividing the recovered data object into data segments. The method further includes dispersed storage error encoding the data segments in accordance with dispersed storage error encoding parameters to produce sets of encoded data slices, wherein a data segment is recoverable from a threshold number of encoded data slices. The method further includes issuing sets of write requests to write the sets of encoded data slices into storage units of a dispersed storage network (DSN).
