Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that the descriptions in this application referring to "first", "second", etc. are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a memory failure recovery method according to a first embodiment of the present application, where the memory failure recovery method can be executed by a memory failure recovery device, and the memory failure recovery device can be implemented in a hardware and/or software manner and is used to recover from a memory failure. The memory failure recovery apparatus may be integrated in a Linux system. The memory failure recovery method comprises the following steps:
s11: and unloading the file system, wherein the file system is mounted with a memory.
Specifically, in the step S11, the file system is unloaded by calling a cancel mount command (umount command). The type of memory is not limited. Such as the memory may be eMMC. A file system is a method and data structure used by an operating system to clarify files of a memory. The software mechanism in the operating system that is responsible for managing and storing file information is called a file management system, referred to as a file system for short. The file system consists of three parts: file system interface, software assembly for manipulating and managing objects, objects and properties. From a system perspective, a file system is a system that organizes and allocates space of a file storage device, is responsible for file storage, and protects and retrieves stored files. In particular, the file system is responsible for creating files for users, storing, reading, modifying, dumping files, controlling access to files, revoking files when a user is no longer in use, and the like. Mount (mounting) refers to a process by which a computer's files and directories on a storage device are made available to a user through the computer's file system by an operating system. Unloading is the reverse operation of mounting. For example, when the usb disk is not used, in order to ensure the data security of the usb disk, the usb disk is pulled out, and the usb disk is first "popped out" in the form of software, and then manually pulled out. Specifically, when the file system is unloaded, the umount command may be called to unload the file system.
S12: after the file system is successfully unloaded, the memory driver is unloaded.
It will be appreciated that after the file system is successfully unloaded, a polling (polling) mode is initiated to unload the memory drive. Polling is a way for a Central Processing Unit (CPU) to decide how to provide services for peripheral devices, and is also called Programmed input/output (Programmed I/O). The concept of the polling method is: the CPU sends out inquiry at regular time to inquire each peripheral equipment whether it needs its service or not in sequence, if so, the peripheral equipment gives service, and after the service is over, the peripheral equipment asks the next peripheral equipment, and then the process is repeated. The memory driver is a driver of the memory. A driver is a special program that enables a computer and a device to communicate with each other, and is equivalent to a hardware interface through which an operating system of the computer can control the operation of the hardware device. The memory drive is not unloaded until the file system is unloaded successfully.
S13: and powering on the memory after powering off the memory for a preset time after the memory drive is unloaded successfully.
It will be appreciated that after the memory drive is successfully unloaded, the polling mode is turned off to power down the memory for a preset time and then powered up. The length of the preset time is not limited, and can be set according to the performance of the memory, for example, the preset time can be 2 s. After the power of the memory is cut off for the preset time, the power is supplied again, so that the normal work of the memory can be ensured, and the successful loading of the memory drive is ensured.
S14: the memory driver is loaded.
It will be appreciated that prior to loading the memory driver, a polling mode may be initiated to load the memory driver. The memory driver is loaded, i.e. the driver for the memory is installed again. After power up, the memory driver is unloaded.
S14: and after the memory driver is loaded successfully, mounting the file system of the memory.
Specifically, in the step S14, the file system is unloaded by calling a mount command (mounting command). And after the memory driver is loaded successfully, the file system of the memory is not mounted. After the file system of the memory is mounted, the memory can recover normal operation. It will be appreciated that the polling mode will be turned off after the file system of the memory is mounted.
The memory failure recovery method provided by the embodiment unloads a file system, wherein the file system is mounted with a memory; after the file system is unloaded successfully, unloading the memory drive; powering on the memory after powering off the memory for a preset time after the memory drive is unloaded successfully; loading a memory driver; after the memory drive is loaded successfully, the file system of the memory is mounted, so that the memory can be quickly restored to normal work after the memory fails, the technical scheme for restoring the memory to normal work is simple, a user cannot feel that the memory fails, the user experience is good, and the hardware cost cannot be increased.
Referring to fig. 2, a second embodiment of the present application also provides a method for recovering a memory failure, and based on the foregoing embodiments, this embodiment provides a solution for determining completion of each step, where the method for recovering a memory failure includes:
s21: and unloading the file system, wherein the file system is mounted with a memory.
S22: and judging whether the file system is unloaded successfully.
A get _ cd function may be set, and when the storage fails and the file system of the storage is unloaded successfully, the get _ cd function returns 0, which triggers unloading of the storage drive. If the unloading of the file system is successful, the process proceeds to step S23, and if the unloading of the file system fails, the unloading of the file system continues.
S23: after the file system is successfully unloaded, the memory driver is unloaded.
S24: and judging whether the memory drive is unloaded successfully.
Preferably, the determining whether the memory drive is successfully unloaded comprises:
and detecting whether the equipment file exists, and if the equipment file does not exist, judging that the unloading of the memory drive is successful.
The device file is an interface to the device driver and is stored in the file system as a regular file. Device files typically provide a simple interface, such as memory, to peripheral devices. If the memory driver is unloaded successfully, the/dev/mmcblk 0 file of the device file does not exist. Whether the memory drive is unloaded successfully can be judged according to whether the detection equipment file exists. It will be appreciated that if there is more than one memory, then there will be more than one device file. And for each memory, detecting whether a device file corresponding to each memory exists. If the unloading of the memory drive is successful, the flow proceeds to step S25. And if the unloading of the memory drive fails, continuing to unload the memory drive.
S25: and powering on the memory after powering off the memory for a preset time after the memory drive is unloaded successfully.
S26: the memory driver is loaded.
S27: and judging whether the memory driver is loaded successfully or not.
Preferably, the determining whether the memory driver is successfully loaded comprises:
and detecting whether the equipment file exists, and if so, judging that the loading of the memory driver is successful.
If the memory driver loading is successful, then the/dev/mmcblk 0 file for the device file exists. Whether the memory driver is loaded successfully can be judged according to whether the detection equipment file exists. If the loading of the memory driver is successful, the process proceeds to step S28, and if the loading of the memory driver fails, the loading of the memory driver is continued.
S28: and after the memory driver is loaded successfully, mounting the file system of the memory.
