Linux file system repairing method, system and device and storage medium

Abstract

The invention discloses a Linux file system repairing method, system and device and a storage medium, and the method comprises the steps: newly adding an input and output control interface in a kernel, and then obtaining file parameters in a to-be-repaired disk through the input and output control interface. Opening the to-be-repaired disk, determining a to-be-repaired file in the to-be-repaired disk according to preset file repair conditions and file parameters, and verifying metadata information of the to-be-repaired file; when the verification is abnormal, calling a repair tool to repair the to-be-repaired file; and after the repair is completed, writing the to-be-repaired disk, and closing the to-be-repaired disk after the writing is completed. According to the file system repairing method provided by the embodiment of the invention, all files in the system do not need to be traversed, and the file needing to be repaired can be determined according to the preset file repairing condition, so that the time consumption of the repairing process is reduced, and rapid repairing is realized.

Description

technical field [0001] The present application relates to the field of computer technologies, and in particular, to a Linux file system repair method, system, device, and storage medium. Background technique [0002] When the Linux system is shut down due to unexpected power outages, the Linux file system may be damaged, making it impossible to enter the system normally. In the related art, the fcsk (file system check, file system check) repair tool is generally used to repair the file system. However, the repair tool needs to traverse, check and repair all files, resulting in a long repair process; and the repair process requires a relatively long time. Large memory, there may be cases where disks with less remaining storage space cannot perform the repair process properly. SUMMARY OF THE INVENTION [0003] The present application aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present application proposes a ...

[0002] When the Linux system is shut down due to unexpected power outages, etc., the Linux file system may be damaged, resulting in failure to enter the system normally

In related technologies, the fcsk (file system check, file system check) repair tool is generally used to repair the file system. However, the repair tool needs to traverse, check and repair all files, resulting in a long repair process; moreover, the repair process requires more time. Large memory, it may appear that the disk with less remaining storage space cannot perform the repair process normally
