Adaptive matching is provided, which is used to automatically match a block size of a transactional file system with an IO size of a client. An example method includes creating a share domain, wherein the share domain is created on a first file system, and a block size of the first file system is a first block size. The method further includes determining a block size of the share domain as a second block size, wherein the second block size is not equal to the first block size. If a block size of a second file system is the second block size, the share domain is migrated from the first file system to the second file system. By implementing the present application, it is possible to simplify user operations, improve operational convenience, and help to reduce storage space fragments and indirect blocks, thereby further improving the performance of a storage system.

Techniques perform data input and output. For example, there is provided a technique for updating a data pattern table. The technique involves: during a time period for establishing or updating the data pattern table: receiving a data write request; making statistics of a frequency of data being written; and writing data frequently used and an identification of the data to a corresponding entry of the data pattern table based on a result of the statistics. Using such a technique, a data pattern table can be customized and data storage efficiency can be improved.
