System and method for managing resource

Abstract

The invention provides a resource management system and a method. The resource management system comprises a file resource-based organization component used for storing the index node of a file provided with idle resources; and a file operating unit used for directly performing resource management to the index node stored in the file resource-based organization component. Because the resource management is performed by using the system, the results of resource allocation can be reused, and the efficiency of resource allocation can be improved; resource recovery is not required as for the filedeletion, and thereby the cost of the resource recovery can be reduced; the modification operation of the related data structure during the processes of resource allocation and recovery is greatly reduced, and the speed for resource management can be increased.

Description

technical field [0001] The invention relates to a data access or recording method, in particular to a resource management system and method. Background technique [0002] Resource management is the management of index node resources and block resources. It is the main functional operation of the file system, and the efficiency of resource management affects the overall efficiency of the file system. [0003] In existing file systems, such as ext2, ext3, JFS, ReiserFS, etc., resource management generally adopts a bitmap method, and the 0 / 1 value of a bit in the bitmap is used to mark the idle / occupied status of the resource described; in addition, Some file systems, such as DCFS2 and GFS, adopt the extended block (extent) method, and use the (starting block number, quantity) two-tuple to represent a continuous idle resource. [0004] Such as figure 1 As shown, the existing resource management system includes a file operation component and a resource organization component. ...

AI Technical Summary

Problems solved by technology

[0006] From the above operation process, it can be seen that the file has always been the role of consuming resources in the existing file system, and the resources recorded in the file can only be used by the file, and cannot be directly used by other files

A large number of block resources are organized into files when they are created, and a large number of block resources are completely recycled when they are deleted; when they are created again, the above block resource allocation operations need to be repeated many times, and the previous block resource allocation results cannot be reused, resulting in Inefficient resource allocation

Block resources can only be used again after recycling to resource organization components, and resources cannot be directly transferred from one file to another, resulting in inefficient resource recycling
