Abstract
Data processing techniques comprise, in response to determining that a storage unit storing first data blocks is damaged, determining storage units associated with the storage unit, and obtaining second data blocks from the storage units, where the second data blocks and the first data blocks are generated by applying to data an error correction code in a first format. The method further comprises recovering the first data blocks based on the second data blocks. In addition, the method comprises generating error correction blocks by applying an error correction code in a second format to the recovered first data blocks, where the second format is different from the first format. The above techniques can reduce input/output operations and shortens the recovery time of data blocks, and further can reduce the risk of data loss even in an extremely bad situation.
