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 incre

Embodiment Construction

[0035] The preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0036] This implementation mode is applied to a specific type of storage operating system, which has the following characteristics: the storage operating system itself is a Linux operating system with a kernel version of 2.6; it uses a self-designed U disk as a storage medium, and is made into 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 and replace; the system’s Boot Loader chooses syslinux, and combines the initrd mechanism to complete the system’s boot process , to achieve booting from the U disk.

[0037] The prepared U disk mainly includes two folders: one is the boot directory, which is used to store the system kernel and bootloader; the other is the netstor directory, which is mainly used to store the contents o...

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...
