A boot file system detection method and related equipment

Abstract

Disclosed in embodiments of the present application is a power-on file system check method, comprising: detecting a first disk partition by means of a kernel driver in a kernel mode; completing the initialization of the first disk partition by means of an initialization function in the kernel driver; performing file system check (fsck) on the first disk partition by means of the initialization function; and reporting a first disk partition event to an initialization process in a user mode. According to the method, the fsck processes of disk partitions are advanced to a disk partition initialization phase and executed in parallel, without blocking a power-on process, avoiding the need to switch every read and write operation of the fsck processes on a disk from the user mode to the kernel mode and then to the user mode, thereby increasing the speed of the fsck processes, and reducing the time consumed by the power-on process.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular to a boot file system detection method and related equipment. Background technique [0002] Terminal equipment is prone to power failure. During the process of reading and writing disk files, if the terminal equipment suddenly loses power, it will easily cause disk file damage. Therefore, in order to ensure that the disk is available, it is necessary to perform a file system check (file system check, FSCK) on the disk partition during the boot process of the terminal device, so as to detect whether the disk partition is damaged. [0003] In the prior art, after the kernel driver in the kernel mode (kernel mode) detects the disk partition, it will report the disk partition event to the user mode (user mode), and the user space process (ueventd) in the user mode monitors the disk partition event After that, the corresponding disk partition nodes will be generated, an...

Problems solved by technology

[0004] In the user state, the init process starts the fsck process. Every time the fsck process reads and writes to the disk (input / output, I / 0), it needs to switch from the user state to the kernel state and then to the user state, which increases the time consumption of the boot process.
