Redundant and high-reliability partitioning method for embedded Linux system

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...

AI Technical Summary

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
