Abstract: This application discloses a super block management method and apparatus. An example method includes: obtaining a parameter of a memory and a type of target data, where the target data is data to be written into the memory; configuring a capacity of a section in a file system based on at least one of the type of the target data or the parameter of the memory, where the configured capacity of the section matches a capacity of a super block in the memory; and managing, based on the configured capacity of the section, a logical address space corresponding to the memory.

Abstract: A data access method performed by a processing device is disclosed. The processing device manages a storage device based on a log-structured file system (LFS), where the processing device writes a target file to the storage device based on an out place update (OPU) mechanism; and the processing device writes file attribute information corresponding to the target file in the storage device to out of band (OOB) data of the storage device, to restore, after abnormal power-off, access to the target file by using the file attribute information stored in the OOB data. In this way, when writing the target file to the storage device, the processing device may write a file attribute corresponding to the target file to the OOB data, so that after abnormal power-off, access to the target file may be restored by using the file attribute information.
