摘要
Aspects of the present disclosure describe methods and systems for optimized re-striping in an erasure encoded storage. In one exemplary aspect, a method may receive a request to re-stripe a plurality of data blocks arranged as a tile in the erasure encoded storage, wherein the request comprises a desired tile width. The method may identify (1) a number of data blocks in the tile and (2) a width of the tile. The method may determine a maximum number of data blocks that do not need to be rearranged when reconfiguring the tile to the desired tile width. Furthermore, the method may determine a tile reconfiguration with the desired tile width that does not rearrange the maximum number of the data blocks of the tile, and may re-stripe the tile in accordance with the tile reconfiguration.
