Method for updating memory operating system

Abstract

The invention relates to a method for updating a memory operating system. The method comprises the following steps of: 1, modifying the memory operating system on a local platform with the same version software system and the same hardware configuration by using a developer; 2, manufacturing a patch.fs file; 3, uploading the patch.fs file which is temporarily stored on a terminal to a disc array on any common terminal which is connected with the disc array by using a user; 4, putting the uploaded patch.fs file into a memory, controlling to move the patch.fs file to a temporary folder by usinga background process, executing the mount operation of a user space content represented by the file, and processing according to a mount result; and 5, after the patch.fs file is successfully updated, restarting the disc array, and completing software update by utilizing the characteristic that a file system supports union mount at a starting guide stage. In the method, the file for realizing thesoftware update has a small occupied space and high safety.

Description

technical field [0001] The invention relates to a software upgrading method, in particular to a software upgrading method constructed for a self-developed storage operating system on a U disk, belonging to the field of computer storage management. Background technique [0002] When current disk array manufacturers develop disk array products, the developed disk array is generally controlled and managed by a storage operating system developed for the disk array. Some storage operating systems are made into a USB boot disk format; the prepared U disk is installed on the motherboard or controller of the brand's disk array in the form of accessories, which is easy to plug in and replace. Every time a user purchases a disk array of this brand, it is equivalent to owning a copy of the storage operating system, and then through the operating system, the storage organization, access and management of data in the disk array are realized. [0003] Among these storage operating system...

Problems solved by technology

[0005] The conventional solution adopted by general development organizations when facing similar problems is to replace the firmware.fs file of the user's existing software system as a whole. This can of course achieve the purpose of software upgrading, but the existing problems are also obvious: one is the file itself The space occupied may be relatively large. On the one hand, when using mobile storage media to copy files, the storage medium needs to have enough free space to ensure the normal copying of files. On the other hand, it undoubtedly increases the use of network methods. The time spent on transmission; secondly, most development organizations do not understand the importance of data security enough, and often provide such files to users in plain text, which is not conducive to preventing some illegal users from deliberately modifying the software. On the other hand, such files may also conflict with ordinary files with the same suffix temporarily generated by the user, causing the system to load the user's ordinary files as system files, thus affecting the normal operation of the system
