Abstract: The method includes: obtaining, in response to a write request for a target data block, a value of a first sub-counter corresponding to the target data block in an integrity tree, where the first sub-counter is a sub-counter of a first shared counter, and a first storage resource of the first sub-counter belongs to a storage resource of the first shared counter; and allocating a second storage resource to the first sub-counter when it is detected that a value obtained after a first value is added to the value of the first sub-counter is greater than a maximum storage value of the first storage resource. In this way, the adjusted storage resource of the first sub-counter is increased, thereby further preventing overflow of the first sub-counter and improving performance of data integrity verification of the integrity tree.
