Problems solved by technology

[0003] In the existing technology, the file system will identify the file type according to the file name or the information embedded in the file, and allocate storage media with different granularities for the file. When the file type is determined, the file management mode is also determined, which is relatively fixed.

Abstract

A file management method and a file system are applied in the technical field of data processing. The file system will monitor the IO access information of the file operation, then determine the IO access mode of the file, and determine the corresponding file management strategy according to the IO access mode; finally, when the obtained file management strategy is inconsistent with the current management method of the file, According to the determined file management policy, adjust the current management mode of the file, such as the storage medium and the granularity of file management, so as to realize the dynamic adjustment of the storage medium and the granularity of file management according to the IO access mode of the file.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a file management method and a file system. Background technique [0002] With the application of NAND flash memory (FLASH) and the emergence of new storage media such as phase change memory (PCM), various media show different read and write characteristics, which requires the file system to adopt different granularity management The method manages the files stored in the storage medium to improve the performance. For example, adopting large-grained management can reduce metadata storage overhead and metadata index search time delay; adopting fine-grained management can ensure effective data access without wasting bandwidth and reduce data migration. [0003] In the prior art, the file system identifies the file type according to the file name or the information embedded in the file, and allocates storage media of different granularities for the file. When the file type ...
