Embodiment Construction

[0031] Refer to figure 1 , The embodiment of the present invention provides a file management method, which includes:

[0032] 101. Divide the file to be stored into multiple data blocks.

[0033] Specifically, when a file is to be stored, the file to be stored can be divided into multiple data blocks according to a set division rule, where the number of data blocks must be less than or equal to the number of storage nodes.

[0034] 102. According to the volume number of the storage node, the multiple data blocks are respectively stored in volumes with the same prefix value on different storage nodes, where the volume number of the storage node includes: the index of the corresponding storage node and the volume location Corresponding prefix value, which is used to distinguish different volumes on the same storage node.

[0035] Since the prefix value is used to distinguish different volumes on the same storage node, the volume number composed of the index of the storage node and the ...

Abstract

The embodiment of the invention provides a file management method, equipment and a memory system, wherein the file management method comprises the following steps of: dividing the file to be stored into a plurality of data blocks; according to the reel number of each storage node, respectively storing the plurality of data blocks to different storage nodes in the reel with the same prefix value; the reel number of the storage node comprises an index corresponding to the storage node and a prefix value corresponding to the reel; and the prefix value is used for distinguishing different reels on the same storage node. Due to the adoption of the technical scheme, the files are easy to store and manage.

Description

Technical field [0001] The present invention relates to the field of storage technology, in particular to a file management method, equipment and storage system. Background technique [0002] With the development of distributed file systems and cluster systems, many technologies applied in local file systems have been transplanted to distributed file systems and cluster systems, such as data redundancy technology. In the local file system, the volumes on different disks of the same storage node are used to store different data blocks of the same file. When a disk of the storage node fails, the contents of the data blocks stored in the corresponding volumes on other disks are used Recover the contents of the data block stored on the failed disk. [0003] In distributed file systems and cluster systems, data redundancy generally refers to the use of multiple copies and storing different copies on different storage nodes. For example, when a file needs to be stored, the file to be st...
