Problems solved by technology

When the hardware of the storage device is damaged or the file system is damaged, the storage device will be remounted as read-only, but the application cannot know in time that the storage device has been remounted as read-only, so it will continue to read and write to the storage device , which in turn will cause the application to fail to access the storage device because the storage device is currently in a read-only state

Embodiment Construction

[0028] In the Linux operating system, mounting refers to attaching a storage device to an existing directory, and by accessing the directory, files in the storage device can be accessed. For some other types of operating systems, mounts have a similar meaning.

[0029] When the hardware of the storage device in the terminal is damaged or the file system is damaged, the storage device will be remounted as read-only. In order to notify applications in the terminal that the storage device is remounted as a read-only state in a timely manner, so as to avoid errors in read and write operations caused by these applications continuing to perform read and write operations on the storage device, the embodiment of the present application provides a storage device Device mounting management method and device.

[0030] Wherein, the storage device in the terminal may include built-in storage and / or external storage.

[0031] The embodiments of the present application are applicable to va...

Abstract

A method and apparatus for mount management of a storage device are disclosed. The method comprises: the operating system kernel detects the file system state of the directory mounted by the storage device, when it is judged that the storage device is remounted as read-only according to the detection result, the following steps are executed: a first notification message is sent to an application frame layer, and the application frame layer notifies the application program to stop accessing the storage device which is remounted as read-only according to the first notification message.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a storage device mounting management method and device. Background technique [0002] Storage devices in mobile devices are divided into built-in storage and external storage. The built-in storage refers to the storage space of the mobile device when it leaves the factory, which can be used for system firmware and software installation. The external storage is usually a pluggable memory card, such as an SD card. [0003] In the Linux operating system, all devices are regarded as files, and the resources of the entire device are integrated into a file directory. If you need to access the files in the storage device, you need to mount the storage device as a file partition to an existing directory, and then access the files in the storage device by accessing the directory. [0004] After storage devices are mounted to existing directories, applications in mobile devices...
