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.

Abstract: The present disclosure discloses a data reconstruction method and apparatus, a computer device, and a storage medium and system, and pertains to the field of data storage technologies. According to the method, a lost first block in a first stripe is directly reconstructed based on a first result obtained from a target quantity of storage devices, so that there is no need to read an unlost block in the first stripe. The first block may be reconstructed provided that the target quantity of first results are obtained. An amount of data of the first result is less than that of the unlost block in the first stripe. Therefore, a data transmission process occupies less network bandwidth, and this improves block reconstruction performance.

Abstract: A resource allocation method includes: determining, by a network-side device based on a maximum quantity of transmissions of a terminal device in a scheduling period, a set including at least two groups of patterns, where any group of patterns and any other group of patterns in the set are corresponding to a maximum of K same first subframes, and the first subframe is a subframe to which a frequency domain resource is allocated; receiving, by the network-side device, resource scheduling request messages sent by at least two terminal devices; determining, by the network-side device, a target group of patterns from the set based on the resource scheduling request messages, where the target group of patterns are in a one-to-one correspondence with the at least two terminal devices; and separately sending, by the network-side device, information about the target group of patterns to the at least two terminal devices.
