Embodiment Construction

[0028] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0029] see figure 1 As shown, a self-rescue method after file system damage includes the following steps:

[0030] S101: After the board is powered on for the first time, it will be able to back up the communication addresses of the front-end and back-end servers. The backup area is the private data area of ​​the non-file system, and will not be damaged due to file system damage. Every time the content of the above key parameters is modified, the backup parameters of the private data area are updated in real time.

[0031] S102: When the BOOT is started, self-inspection is first performed, and once it is found that the file system is damaged, or the version file and the backup version file are damaged, enter the exception processing branch.

[0032] Specifically, firstly, record the abnormal branch identifier; secondly, send a f...

Abstract

The present application discloses a self-rescue method and device for a damaged file system. The method includes: a fault warning message is sent to a background server when it is found during boot of a device that a file system is damaged; the device receives an acknowledgement message from the background server, wherein the acknowledgement message contains a path and file name of a backup version selected by the background server according to a product type; and the device downloads a version file and reboots from the version file. The device, when finding during the boot that the file system is damaged, implements network communications between the foreground and the background prior to switching to a large version, in order to acquire a version from the background server actively and reload it, so that the damaged file system is self-repaired automatically without manual interference.

Description

technical field [0001] The invention belongs to the technical field of network management, and in particular relates to a self-rescue method and equipment after a file system is damaged. Background technique [0002] A file system is the method and data structure that an operating system uses to identify files on a disk or partition; that is, the method by which files are organized on a disk. Also refers to the disk or partition used to store files, or the type of file system. File system is the abbreviation of file management system, which refers to the software organization responsible for managing and storing file information in the operating system. The file system consists of three parts: software related to file management, managed files, and data structures required for file management. From a system perspective, a file system is a system that organizes and allocates file storage space, is responsible for file storage, and protects and retrieves stored files. Speci...
