Problems solved by technology

[0004] In the current common Linux deployment scheme, there is usually only one system disk, and the entire Linux system is placed on a system partition, without self-test and repair capabilities, and the current system disk generally uses electronic disks, including NandFlash , DOM, etc., all have a limit on the maximum number of reads and writes. Once they experience multiple unexpected power failures and run in harsh environments for a long time, the service life of the system disk will be greatly reduced. Once the system disk partition or system disk fails, Then the whole system will not start normally
This will bring bad experience and loss to users

Embodiment Construction

[0013] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and specifically implement how the present invention uses technical means to solve technical problems and achieve technical effects.

[0014] A redundant and highly reliable embedded Linux system partition method:

[0015] This embodiment mainly includes the following steps:

[0016] Step 101: Analyze the Linux system structure and file composition from the system level, and divide the system into kernel file modules, boot file modules, system file modules, etc. functionally. Among them, the system file module is divided into kernel module, user mode tool, library file, configuration file, log file, etc. according to specific functions. Its purpose is to divide the system into multiple low-coupling modules, which can be deployed in different partitions of the system disk.

[0017] Step 102: according to the...

Abstract

The invention discloses a redundant and high-reliability partitioning method for an embedded Linux system and belongs to the field of computer systems. The method specifically comprises the following steps: (1) analyzing the structure and file constitution of the Linux system; (2) additionally installing a system disc based on a single system disc; (3) partitioning the system disc into four partitions; (4) detecting a starting system of the system disc by virtue of a GRUB (GRand Unified Bootloader) guiding method; (5) carrying out a self-repairing function on a dual-standby system disc; (6) starting the Linux system; and (7) carrying out high-reliability management on the dual-standby system disc. The redundant and high-reliability partitioning method has the beneficial effects that by providing a reliable and reasonable deployment method for the embedded Linux system, the reliability of the system during the operation is substantially increased; the frequency of IO (input and output) access to the system disc during the operation of the system is substantially decreased; by reasonably partitioning files of the Linux system and storing the files into different partitions, the interaction among the files is reduced; by utilizing two redundant backup system discs, the reliability of the system is greatly improved.

Description

[0001] technical field [0002] The invention relates to a method for partitioning a Linux system, which belongs to the field of computer systems, in particular to a method for partitioning a redundant and highly reliable embedded Linux system. Background technique [0003] In recent years, embedded technology has been greatly developed. Embedded Linux is widely used in information appliances due to its open source code, small kernel, high efficiency, completely free, good cross-platform, and good tailoring. , mobile phones, automobiles, network equipment, medical electronics, industrial control, telecommunication, and aerospace fields, embedded Linux applications have penetrated into all aspects of people's daily lives. [0004] In the current common Linux deployment scheme, there is usually only one system disk, and the entire Linux system is placed on a system partition, without self-test and repair capabilities, and the current system disk generally uses electronic disks...
