Abstract
Techniques for processing data involve receiving an access request for a logical block used for storing data, the access request including a logical block address for the logical block. Such techniques further involve determining, if it is determined that the logical block address is in a used address space, an index entry corresponding to the logical block address from index entries, the index entry indicating arrangements of logical blocks on a corresponding pool stripe, wherein the pool stripe includes disk blocks from disks in a disk pool, and data blocks form at least one data stripe for a disk array. Such techniques further involve determining a target block corresponding to the logical block based on the index entry. Such techniques further involve processing the access request by using the target block. Accordingly, the processing speed of sequential I/O operations is improved, time is saved, and user experience is improved.
