Access permission is enabled. For example, in response to receiving an access request for a target file from a first client, a type of an access permission contained in the request is determined. Then, a first type of access permission is determined that can be assigned to the first client if it is determined that the contained type is in a set of reference types. Further, it may be determined that a second type of access permission applicable to be assigned to the target file. It can then be determined, from the first type and the second type, a target type of an access permission to be assigned to the first client. As a result, the probability of assigned access permissions being interrupted can be reduced, the performance of a client and a server is increased, efficiency is increased, and the user experience is improved.

Method, electronic device, and computer program product for processing access permission

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.
