Embodiment Construction

[0049] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] In the following description, use of suffixes such as 'unit', 'part' or 'unit' for denoting an element is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, 'unit', 'part' or 'unit' may be used in combination.

[0051] see figure 1 , figure 2 and image 3 , in order to achieve the above object, the first embodiment of the present invention provides a cluster allocation method for a multi-host FAT file system, which is applied to a FAT sharing system for a multi-host FAT file system, and the FAT sharing system includes a host end and an independent At the storage module end other than the host end, the storage module end is communicatively connected to the host end, and the storage module end stores a FAT table; the method includes the following steps...

Abstract

The invention discloses a cluster allocation method and system oriented to a multi-host FAT file system. The method is applied to an FAT sharing system oriented to the multi-host FAT file system, andthe FAT sharing system comprises a host end and a storage module end independent of the host end, wherein the storage module end is in communication connection with the host end, and an FAT table is stored in the storage module end. The method comprises the following steps: pre-allocating non-overlapping cluster domains to each host in a cluster of the FAT; detecting a cluster pool application request sent by the host end; according to the cluster pool application request and the cluster domain allocated to the host end sending the cluster pool application request, performing cluster pool allocation on the host end sending the cluster pool application request. The technical scheme of the invention aims to solve the problem of low data writing efficiency caused by frequent interaction of the FAT file system under multiple hosts.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a cluster allocation method oriented to a multi-host FAT file system and a FAT sharing system oriented to a multi-host FAT file system. Background technique [0002] FAT (File Allocation Table, file configuration table) is a common file system. Currently, the existing FAT file system on the market can only realize the file system operation under a single host. The formation of read-write conflicts is likely to cause data overwriting and file damage, and data security cannot be guaranteed. Therefore, the FAT file system cannot handle multi-host requests correctly and does not support multi-host requests. [0003] For each host, since the clusters in the FAT file system are allocated one by one, when writing large files or multiple small files, it is necessary to apply for resources from the storage module multiple times, resulting in frequent interactions and greatly reducing t...
