File Management Method and File System

摘要

A file management method and a file system are applied to the field of data processing technologies. The file system monitors input/output (IO) access information for operating a file, then determines an IO access mode of the file, determines a corresponding file management policy according to the IO access mode, and finally, when the obtained file management policy is inconsistent with a current management manner of the file, adjusts, according to the determined file management policy, the current management manner of the file, for example, a storage medium and a file management granularity, so as to dynamically adjust the storage medium and the file management granularity of the file according to the IO access mode of the file.

1. A file management method, comprising:
acquiring input/output (IO) access information for operating a file; determining an IO access mode corresponding to the IO access information; matching the determined IO access mode with a preset mode matching library to obtain a file management policy corresponding to the determined IO access mode, wherein the file management policy comprises a file management granularity, a file storage medium type, or the file management granularity and the file storage medium type, wherein the mode matching library comprises a correspondence between the IO access mode and the file management policy; and adjusting a current management manner of the file when the current management manner of the file is inconsistent with the file management policy corresponding to the determined IO access mode such that the adjusted current management manner is consistent with the file management policy corresponding to the determined IO access mode.
