Abstract
Erasure code for data is generated by: calculating the size and bytes of an erasure code block, calculating a number of stripes for the erasure code, and generating each stripe of each block for the erasure code, such that the stripes alternate in a pattern for each block, and saving hashes. A portion of the data is repaired by: for each block of the portion of the data, calculating the stripe of the block, identifying each hash for which the hash of the block of the portion of data does not match the saved hash of the block as a bad block, and for each identified bad block, generating a repair block for the bad block based on the stripe of the block and corresponding block of the data in the erasure coding for the data.
