Abstract: A method and apparatus for determining stripe consistency, including an operation node that obtains n groups of CRC data blocks corresponding to a target stripe, where the target stripe includes n first data blocks, the n first data blocks include k original data blocks and m EC data blocks of the k original data blocks, the n groups of CRC data blocks are respective CRC data blocks of n groups of second data blocks, one group of second data blocks includes m transformation results obtained by performing m times of EC transformation on one first data block, both k and m are positive integers, and n=m+k.
