Abstract: A method including determining a to-be-verified data block among a plurality of data blocks corresponding to a predetermined file in a distributed storage system, wherein a storage node where the to-be-verified data block is located comprises a storage node that meets a load balancing strategy in the distributed storage system; and verifying the to-be-verified data block. The present disclosure solves the technical problem in the conventional technologies in which the read/write performance at a user front end is affected during a data verification process.

Abstract: Embodiments of the disclosure provide a method and apparatus for upgrading a distributed storage system, and the disclosure relates to the field of distributed computer technology. In the disclosure, a client sends write requests regarding the same to-be-written data to a plurality of data servers at the same time; then how many data servers the to-be-written data is successfully written into is analyzed; it is determined whether the number of the successful writes is greater than a pre-defined number; and first feedback information or second feedback information is sent to each data server having a successful write according to the determining result. The data server then determines whether it is in an upgradeable state or a non-upgradeable state according to the received first feedback information or second feedback information. Based on the state of the data server, an upgrade control server may select to notify, in a rolling manner, the data server to perform an upgrade operation.
