Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Socket Communication is an Inter-Process Communication (IPC) mechanism, and in an operating system, an Application Programming Interface (API) is usually provided for an Application program, which is called a Socket API. Applications may use network sockets through a socket interface for data exchange. The operating system may decide, based on the socket address, that data should be delivered to a particular thread or thread. In Socket communication, HTTP provides a specific form of encapsulating or displaying data, and Socket provides a capability of network communication.

Binder communication is similar to Socket communication, is an efficient inter-process communication mechanism, and can realize sending data of a process A to a process B. At present, more and more terminal devices communicate based on a Binder communication mechanism, for example, a terminal device includes a Volume Daemon module (Vold) and a Storage management Service module (Storage Manager Service), and when an external Storage device, such as a memory card, a usb disk, or the like, is mounted, an interaction between the external Storage device management module and the Storage management Service module is required, where the interaction may be based on Binder communication. The terminal devices include, but are not limited to, mobile phones, digital cameras, portable computers, and other terminal devices.

However, the inventor finds that, in the process of mounting the external storage device based on Binder communication by the external storage device management module and the storage management service module, if the external storage device management module and the storage management service module are blocked in the Binder calling process, a watchdog program in the system may be triggered, so that the system does not respond, and abnormal situations such as system deadlock or screen fixation occur.

Therefore, in order to solve the above-mentioned defect, an embodiment of the present application provides a mount processing method, as shown in fig. 1, specifically, the method includes: s101 to S104.

S101: the storage management service module sends a first calling instruction to the external storage device management module.

In this embodiment, the terminal device includes an external storage device module and a storage management service module, where the external storage device management module is a management and control center of an external storage system in the operating system platform and is a background process for managing and controlling the external storage device of the operating system platform. The functions mainly comprise: the method comprises the steps of plug-in and pull-out event detection of the external storage device, mounting, uninstalling and formatting of the external storage device and the like. The storage management service module is a module for communicating a system framework layer of the operating system with an external storage device management module, and simultaneously provides an access interface of the storage device and a mounting message broadcast of the storage device for the application program. It should be noted that, the external storage device management module and the storage management service module are based on inter-process communication, and if the communication process between the external storage device management module and the storage management service module is blocked, the system may not respond.

After the external storage device is inserted into the terminal device, the terminal device needs to mount the external storage device, and after the external storage device is successfully mounted, the application program on the terminal device can access the external storage device.

In one embodiment, when the terminal device needs to mount the external storage device, the storage management service module sends a first call instruction to the external storage device management module.

S102: and the external storage equipment management module responds to the first calling instruction, executes detection operation, sets the detection state identifier of the external storage equipment as the detection identifier, and returns the detection state identifier.

Wherein the detecting operation is to detect whether a file system of the external storage device is abnormal.

The detection-in-detection identifier is used for indicating the storage management module that the external storage device management module is executing the detection operation and is not detected completely, so that when the external storage device management module returns the detection state identifier, the storage management module is the detection-in-detection identifier based on the detection state identifier, and can know that the external storage device is detecting and is not detected completely. Specifically, after the terminal device detects an insertion event of the external storage device, the external storage device management module creates the external storage device and correspondingly stores device information of the external storage device, where the device information includes a detection status identifier.

In some embodiments, the detecting the duration includes detecting whether the file system is abnormal and detecting when the external storage device management module repairs the file system when the file system is abnormal. For example, the file system of the external storage device is damaged too much, which may cause that the time taken for the external storage device management module to attempt to repair the file system of the external storage device is too long, and the too long repair time will cause the system to be stuck.

In this embodiment, in response to the first call instruction, the external storage device management module executes the detection operation respectively, and sets the detection state identifier of the external storage device as the in-detection identifier, and returns the detection state identifier, so that the external storage device management module and the storage management service module can end without waiting for the completion of the detection operation based on the interaction process of the first call instruction, thereby avoiding system non-response due to the interaction process jam based on the first call instruction caused by an excessively long detection time, and specifically, system non-response includes system blocking or screen fixing (screen is blocked for a long time and is still, which may also be referred to as a frozen screen or a hang machine) and other system abnormal conditions, thereby preventing the system non-response caused by the insertion of an abnormal external storage device, and improving the system stability.

Specifically, for example, in response to the first call instruction, the external storage device management module may set a detection state identifier of the external storage device to be a detection identifier such as "checking", and after the external storage device management module returns "checking", the storage management service module may learn that the external storage device is detecting according to the storage state identifier of the external storage device being "checking".

S103: and when the detection operation is completed, the external storage equipment management module sends a detection completion instruction to the storage management service module.

In this embodiment, when the detection operation is completed, the external storage device management module sends a detection completion instruction to the storage management service module to notify the storage management service module that the detection operation on the external storage device is completed, so that the storage management service module can perform the next operation.

In one embodiment, if the detection duration of the detection operation exceeds the specified time, the detection operation is ended, and at this time, the detection operation is completed, and the external storage device management module sends a detection completion instruction to the storage management service module. It should be noted that, since the external storage device management module attempts to repair the file system when the file system of the external storage device is abnormal, if the repair time is too long and the detection time consumed before the repair is successful exceeds a specified time, there is a case where the file system of the external storage device is still abnormal when the detection operation is completed. That is, when the detection operation is completed, the file system of the external storage device may be abnormal or non-abnormal. The non-abnormal condition includes that the file system is normal before detection, and may also include that the external storage device is abnormal when just inserted, but is repaired by the external storage device management module within a specified time to recover to normal.

As another embodiment, if the detection duration of the detection operation exceeds the specified time, the detection operation is not considered to be completed, that is, if the detection duration is too long and the detection operation is not completed within the specified time, the detection operation is considered to be not completed and a detection completion instruction is not sent to the storage management service module, so that the storage management service module cannot perform the next operation on the external storage device. Specifically, since the file system of the external storage device is damaged too much, the external storage device management module cannot complete the repair of the damaged file system within a specified time.

It should be noted that, because the external storage device management module completes one return in response to the first call instruction, that is, when the call thread is finished, the detection operation performed by the external storage device management module on the external storage device is not based on a thread of cross-process communication with the storage management service module, but based on a thread in an internal process of the external storage device management module, even if the detection duration is too long, the system process cannot be blocked, and no response of the system can be caused, so that system blocking or screen fixing caused by inserting an abnormal external storage device into the terminal device can be prevented, and the system stability is improved.

S104: and the storage management service module informs the external storage device management module to mount the external storage device based on the detection completion instruction.

The storage management service module can know that the detection operation is completed based on the detection completion instruction, and at the moment, informs the external storage device management module to mount the external storage device.

Therefore, compared with the prior art in which the external storage device management module returns after completing the detection operation and the mounting operation, the embodiment separates the execution of the detection operation and the mounting operation, so that the external storage device management module returns the detection state identifier before completing the detection operation to end the thread of cross-process communication with the storage management service module, and then mounts the external storage device management module after completing the detection operation.

Referring to fig. 2, a mount processing method provided in the embodiment of the present application is shown, specifically, the method includes: s201 to S207.

S201: the storage management service module sends a first calling instruction to the external storage device management module.

As an embodiment, the first call instruction includes a detection instruction, and specifically, the detection instruction may be a function Check for detecting whether the file system is abnormal or not and whether there is an error or may be another interface function for detecting whether the file system is abnormal or not, which is not limited in this embodiment. Based on the detection instruction, the detection state identifier can be set or updated. In this embodiment, the storage management service module sends the detection instruction to the external storage device management module through a Binder call. Specifically, the storage management service module calls a function Check to the external storage device management module based on Binder communication, so that the external storage device management module can execute the function Check. Therefore, cross-process calling functions can be conveniently realized based on the Binder communication.

As another embodiment, the detection instruction may be preloaded, that is, the first call instruction does not include the detection instruction, at this time, the storage management service module sends the first call instruction to the external storage device management module, so that the external storage device management module can respond to the first call instruction and execute the preloaded detection instruction, thereby reducing inter-process communication data amount, reducing function loading time, improving communication efficiency, improving detection efficiency, and further facilitating improvement of mounting efficiency on the external storage device.

S202: and the external storage equipment management module responds to the first calling instruction, executes detection operation, sets the detection state identifier of the external storage equipment as the detection identifier, and returns the detection state identifier.

For example, if the flag bit is a detection flag such as "Checking" indicating that the external storage device management module is performing a detection operation on the external storage device and is not detecting, the storage management service module may obtain that the current detection state is performing a detection operation and is not detecting.

In this embodiment, in response to the first call instruction, the external storage device management module may perform a detection operation and set a detection status flag of the external storage device based on two different threads, respectively, and return the detection status flag. Specifically, the external storage device management module sets a detection state identifier of the external storage device as a detection-in-process identifier based on the first thread in response to the first call instruction, and returns the detection state identifier so that the first thread returns that execution is finished immediately after receiving the first call instruction, and the external storage device management module executes a detection operation based on the second thread in response to the first call instruction.

Wherein the first thread is a cross-process thread based on a Binder call, namely a main thread, and the second thread is a thread within the external storage device management module process, and thus, after receiving the first call instruction through the first thread, immediately returning to the end of execution, so that the thread called by the Binder can be timely ended, and the second thread is started to execute the actual detection operation, so that the actual detection time length and the repair time length contained in the actual detection time length do not influence the main thread, the detection operation which possibly causes the Binder calling to be blocked is executed based on the second thread, so that the first thread based on the Binder calling can be responded timely and even quickly, the system non-response caused by overlong detection time is well avoided, the abnormal conditions such as system blocking or screen fixing caused by abnormal external storage equipment insertion are prevented, and the stability of the system is greatly improved.

As an embodiment, the first process is performed before the second process, and specifically, in response to the first call instruction, the external storage device management module sets the detection state identifier as the in-detection identifier based on the first thread, returns the detection state identifier, then starts the second thread, and executes the detection operation based on the second thread.

As another embodiment, the first process and the second process are performed simultaneously, specifically, the external storage device management module responds to the first call instruction, sets the detection state identifier, starts the second thread, and executes the detection operation based on the second thread, and the detection state identifier can be immediately returned before the detection operation is completed.

The detecting operation is to detect whether the file system of the external storage device is abnormal, and to repair the abnormal file system. It should be noted that the detection operation includes an operation of repairing the abnormal file system when the abnormality is detected, so in this embodiment, the detection duration includes a repair duration. Specifically, if the file system is damaged, the file system is abnormal, and if the file system is not damaged, the file system is normal, and the external storage device management module tries to repair the abnormal file system when the file system is abnormal. Further, if the repair is completed, the file system is not damaged, and it can be considered as normal without exception.

In some embodiments, if the file system is normal or the file system is abnormal and the repair is complete, the external storage device management module determines that the detection operation is complete, and if the file system is abnormal and the repair is not complete, the file system is still in an abnormal state and the external storage device management module determines that the detection operation is not complete. Wherein:

as a way, if the file system is normal or the file system is abnormal and the repair is completed, the external storage device management module determines that the detection operation is completed; if the file system is abnormal and cannot be repaired, the external storage device management module judges that the detection operation is not finished. Thus, the detection operation is not limited in length, and when the file system is abnormal, it is determined that the detection operation is not completed. Thus, when the repair is completed, it can be determined in time that the inspection operation has been completed, so that the next operation can be performed.

As another mode, a preset time length is correspondingly set for the detection operation of the external storage device management module, and when the file system is abnormal and the repair is not completed within the preset time length, that is, the detection time length exceeds the preset time length, it is determined that the detection operation is not completed. Specifically, if the file system is detected to be normal, repair is not needed at this time, and the external storage device management module determines that the detection operation is completed; if the file system is detected to be abnormal and the repair is completed within the preset time length, the external storage device management module judges that the detection operation is completed; if the detection duration exceeds the preset duration but the repair is not completed, the external storage device management module detects that the file system is abnormal, but the damaged file system is not repaired within the preset duration, and the detection operation is determined to be not completed. Therefore, the execution time of the detection operation can be controlled, and the response can be made in time so as to carry out the next operation, thereby ensuring the detection efficiency, avoiding no response caused by overtime detection and improving the usability of the system.

In other embodiments, a preset time length is set for the detection operation of the external storage device management module, and when the file system is abnormal and the repair is not completed within the preset time length, that is, the detection time length exceeds the preset time length, it is still determined that the detection operation is completed. Specifically, if the file system is normal or the file system is abnormal and the repair is completed, the external storage device management module determines that the detection operation is completed, and if the file system is abnormal and the repair is not completed within a preset time period, the file system is still in an abnormal state, and at this time, the external storage device management module still determines that the detection operation is completed. That is, the detection operation may be performed for a preset duration at most, and when the preset duration is reached, it is determined that the detection operation is completed, where the file system may be normal or abnormal. Therefore, the execution time of the detection operation can be controlled, the detection operation is still judged to be completed when the file system is not repaired, and the response can be made in time so as to carry out the next operation, so that the detection efficiency is ensured, the detection overtime and no response are avoided, and the system usability is improved.

Further, when the detection duration exceeds the preset duration, the external storage device management module may terminate the detection operation, or may not terminate, and the specific implementation manner is as follows:

in an embodiment, when the detection duration exceeds the preset duration, the external storage device management module may terminate the detection operation, save resources, and improve system availability.

In another embodiment, when the detection duration exceeds the preset duration, the external storage device management module may not terminate the detection operation, so that the detection operation continues, specifically, when the file system is damaged too much, the external storage device management module needs to complete the repair of all abnormal file systems, the required duration is long, and the required duration may exceed the preset duration, at this time, the detection operation is not interrupted when the detection duration exceeds the preset duration, so that the external storage device management module may continue to repair, therefore, there is a possibility that the repair is completed before the mount operation is performed, and at this time, the external storage device whose detection operation is not completed still has a possibility that it can be successfully mounted. For specific implementation, reference may be made to the following embodiments, which are not described in detail herein.

Further, in this embodiment, when the detection time exceeds the preset time, S204 may be executed; when the detection time length does not exceed the preset time length, S203 may be performed.

S203: and when the detection duration exceeds the preset duration, the external storage equipment management module sets the detection state identifier as a detection abnormal identifier.

The detection state identifier further comprises a detection abnormity identifier, and the detection abnormity identifier can be used for indicating that the storage management service module detects abnormity currently, namely the detection time length exceeds the preset time length and is not repaired, and at the moment, the file system of the external storage device is still abnormal.

In this embodiment, when the detection duration exceeds the preset duration, the external storage device management module sets the detection status flag as the detection abnormality flag. Specifically, in an implementation, the detection exception identifier may be a character string such as a number, a letter, a word, and the like, and the character string is used to represent that the file system is still abnormal after the detection operation, and may be preset by the system or may be self-defined, so that the file system abnormality may be known through the detection exception identifier.

When the file system is abnormal and the repair is not completed within the preset time, the external storage device is not mounted by setting the abnormal detection identifier when the abnormal detection identifier is detected, so that unnecessary resource consumption is reduced, and the response efficiency is improved. Specific implementation manners can be seen in the following embodiments, which are not described herein again.

S204: and when the detection operation is completed, the external storage equipment management module sends a detection completion instruction to the storage management service module.

In this embodiment, when the detection operation is completed, the file system of the external storage device may be normal or abnormal, where normal includes a case where the file system is normal, and a case where the file system is abnormal but the repair is completed.

As an implementation manner, if the file system is abnormal and is not repaired within the preset time length, that is, the detection time length exceeds the preset time length, it is still determined that the detection operation is completed, at this time, the detection completion instruction is sent to the storage management service module through the external storage device management module, so that the storage management service module can know that the current external storage device completes the detection operation by receiving the detection completion instruction, and can mount the file system. In this case, the file system of the external storage device may be abnormal or non-abnormal.

As another embodiment, if the file system is abnormal and the repair is not completed within the preset time length, that is, the detection time length exceeds the preset time length, it is determined that the detection operation is not completed, and at this time, the detection completion instruction is sent to the storage management service module through the external storage device management module, so that the storage management service module can know that the current external storage device is normal and mount the file system by receiving the detection completion instruction. At this time, the file system of the external storage device is non-abnormal, that is, when the file system of the external storage device is still abnormal, the detection completion instruction is not sent.

S205: and the storage management service module informs the external storage device management module to mount the external storage device based on the detection completion instruction.

In this embodiment, the storage management service module may determine that the current external storage device has completed the detection operation based on the detection completion instruction, and may mount the external storage device, and at this time, notify the external storage device management module to mount the external storage device. Therefore, the detection operation and the mounting operation are executed in different threads, and mounting is carried out only when the condition that the file system of the external storage device is normal is judged through the detection operation, so that the mounting success rate and efficiency can be improved.

S206: and when the external storage device management module mounts the external storage device, determining whether the detected abnormal identifier can be found.

In some embodiments, if the file system is abnormal and is not repaired within a preset time length, that is, the detection time length exceeds the preset time length, it is still determined that the detection operation is completed, and when the external storage device management module mounts the external storage device, it is determined whether the detection abnormal identifier can be found, specifically, for example, based on a flag bit representing a detection state, it is determined whether the detection state identifier on the flag bit is a detection abnormal identifier; for another example, it can directly search whether the corresponding external storage device stores the detection exception identifier.

In other embodiments, if the file system is abnormal and the repair is not completed within the preset time period, that is, the detection time period exceeds the preset time period, it is determined that the detection operation is not completed, then S206 to S207 are not performed after S205, at this time, the file system of the external storage device is non-abnormal, and it is not necessary to search for a detection abnormality identifier.

Further, if the detection abnormal identifier can be found, S207 may be executed; if not, the mounting operation can be continuously executed.

S207: if so, the mounting of the external storage device is stopped.

If the detected abnormal identifier can be found, the external storage device management module judges that the file system of the external storage device is abnormal, and the external storage device is stopped to be mounted, so that the consumption of running resources can be reduced, the running efficiency of the system is improved, and the mounting efficiency is improved.

It should be noted that, for the parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not described herein again.

According to the mount processing method provided by the embodiment, the detection operation and the mount operation are executed in different threads, after the external storage device management module receives the first call instruction, the external storage device management module immediately returns to enable the thread called by the Binder to be timely ended, and the second thread is started to execute the actual detection operation, so that the actual detection time is long, the repair time also included in the external storage device management module does not influence the main thread, namely the detection operation possibly causing the Binder call to be blocked is executed based on the second thread, the system unresponsiveness caused by overlong detection time is avoided, the abnormal conditions such as system blocking or screen fixing and the like caused by abnormal external storage device insertion are prevented, and the stability of the system is greatly improved. In addition, whether the detection abnormal identification can be found or not is determined, so that the external storage device management device continues mounting when the file system of the external storage device is abnormal, the mounting success rate and efficiency can be improved, in addition, the external storage device management module does not mount when the file system is abnormal, unnecessary resource consumption can be reduced, and the system operation efficiency is improved.

In addition, when the detection time exceeds the preset time, the method can be ended without carrying out the next operation. Specifically, referring to fig. 3, the method includes: s301 to S303.

S301: the storage management service module sends a first calling instruction to the external storage device management module.

S302: and the external storage equipment management module responds to the first calling instruction, executes detection operation, sets the detection state identifier of the external storage equipment as the detection identifier, and returns the detection state identifier.

S303: and when the detection duration exceeds the preset duration, the external storage equipment management module sets the detection state identifier as a detection abnormal identifier.

In this embodiment, when the detection duration exceeds the preset duration, the method is ended, so that when the file system is abnormal and the repair is not completed within the preset duration, the storage management service module is not notified to end the method, which can greatly reduce the consumption of the operation resources and improve the operation efficiency of the system.

Further, as a mode, when the detection duration exceeds the preset duration, S303 may be executed first, and then the method is ended. At this time, the external storage device management module sets the detection state identifier as the detection abnormal identifier, so that when the storage management service module obtains the detection state identifier of the external storage device, it can be known that the file system of the external storage device is in an abnormal state, and thus, a user can try to mount the file system again in time.

Alternatively, when the detection duration exceeds the preset duration, S303 may not be executed, and the method may be ended. At this time, the storage management service module considers that the external storage device is always in detection and still performs detection operation, and specifically, the detection state of the external storage device is always "Checking".

S304: and when the detection operation is completed, the external storage equipment management module sends a detection completion instruction to the storage management service module.

S305: and the storage management service module informs the external storage device management module to mount the external storage device based on the detection completion instruction.

S402: and the external storage equipment management module responds to the first calling instruction, executes detection operation, sets the detection state identifier of the external storage equipment as the detection identifier, and returns the detection state identifier.

S403: and when the detection operation is completed, the external storage equipment management module sends a detection completion instruction to the storage management service module.

The above embodiments of S401 to S403 refer to the foregoing embodiments, and are not described herein again.

S404: and the storage management service module responds to the detection completion instruction and sends a second calling instruction to the external storage device management module.

The second call instruction is used for informing the external storage device management module to mount the external storage device.

As an embodiment, in response to the detection completion instruction, the storage management service module sends a Mount instruction to the external storage device management module through a Binder call, where the second call instruction includes the Mount instruction, for example, the Mount instruction may be a function Mount for mounting the external storage device, or may be another interface function for mounting the external storage device, which is not limited in this embodiment. Specifically, the storage management service module calls a function Mount to the external storage device management module based on Binder communication, so that the external storage device management module can execute the function Mount and perform Mount operation.

As another embodiment, the mount instruction may be preloaded, that is, the second call instruction does not include the mount instruction, at this time, the storage management service module sends the second call instruction to the external storage device management module, so that the external storage device management module may execute the preloaded mount instruction in response to the second call instruction, reduce the amount of inter-process communication data, reduce function loading time, and improve communication efficiency and mount efficiency at the same time.

Referring to fig. 5, a mount processing method provided in the embodiment of the present application is shown, specifically, the method includes: s501 to S507.

S501: the storage management service module sends a first calling instruction to the external storage device management module.

S502: and the external storage equipment management module responds to the first calling instruction, executes detection operation, sets the detection state identifier of the external storage equipment as the detection identifier, and returns the detection state identifier.

S503: and when the detection operation is completed, the external storage equipment management module sends a detection completion instruction to the storage management service module.

S504: and the storage management service module responds to the detection completion instruction and sends a second calling instruction to the external storage device management module.

S505: and the external storage device management module responds to the second call instruction and judges whether the file system of the external storage device is abnormal or not according to the detection state identifier.

In this embodiment, the external storage device management module, in response to the second call instruction, determines whether the file system of the external storage device is abnormal according to the detection status identifier corresponding to the external storage device. Specifically, if the current detection status flag is a detection abnormality flag, the file system of the external storage device is abnormal, otherwise, the file system is normal.

In this embodiment, after S505, if not abnormal, S506 may be executed; if so, S508 may be performed.

S506: and the external storage device management module acquires the mounting result.

If the external storage device management module is not abnormal, the external storage device management module detects that the file system of the external storage device is not abnormal, and the external storage device management module executes mounting operation on the external storage device to obtain a mounting result. Specifically, the external storage device management module executes Mount operation on the external storage device by executing a Mount function Mount based on a Mount instruction, such as a Mount function Mount, to obtain a Mount result. Wherein the mounting result comprises mounting success and mounting failure.

S507: and the external storage equipment management module sets a mounting state identifier according to the mounting result.

Specifically, the mount state identifier may be a flag bit used for representing the mount state, for example, if the mount state identifier is "unmount table", it represents that the external storage device cannot be mounted, and if the mount state identifier is "mounted", it represents that the external storage device is mounted. It should be noted that, as long as the mount state identifier can be used to represent the mount state, the naming form of the mount state identifier is not limited otherwise in this embodiment.

As an embodiment, if the mount is successful, the mount status flag is set as a mounted flag, such as "mounted"; if the mount fails, the mount state identifier is set as an unmounted identifier, such as an unmount table, or is set as an unmounted identifier, such as an unmounted identifier. Therefore, the storage management service module can acquire the corresponding mounting result by acquiring the mounting state identifier.

S508: and setting the mounting state identifier of the external storage device as a mounting-unavailable identifier.

If the external storage device management module is abnormal, the external storage device management module detects that the file system of the external storage device is abnormal, and the mount state identifier of the external storage device is set to be the mount-unavailable identifier, so that the external storage device management module cannot mount the external storage device. When the file system is abnormal, the probability of successful mounting of the external storage device is low, so that the probability of successful mounting can be judged by judging whether the file system of the external storage device is abnormal or not, the prejudgment is made before the mounting operation is actually executed, and the mounting is stopped when the file system is abnormal, so that the resource can be saved, and the mounting efficiency is improved.

As an implementation manner, after S508, the method may be ended, that is, the method may be ended after the mount state identifier is set, so that the storage management service module may obtain the mount state identifier, and thus it is known that the currently inserted external storage device cannot be mounted, so that a user may take measures to mount the external storage device again, for example, reinsertion, and user experience of the user in mounting the external storage device is improved.

As another embodiment, the method may be ended before S508, that is, if the external storage device management module determines that the file system of the external storage device is abnormal, the method may be ended without performing S508. Further saving the running resources required for mounting, because it is difficult to Mount the external storage device successfully when the file system is abnormal, the present embodiment may end the method by not performing the actual mounting operation, for example, not performing the function Mount and the like, when the file system is abnormal, thereby reducing the unnecessary running resources.

As another embodiment, the mount disabled flag may be sent to the storage management service module after S508, so that the storage management service module may know the current mount state of the external storage device. For specific implementation, reference may be made to the following embodiments, which are not described herein again.

In the mount processing method provided in this embodiment, because the probability of successful mount of the external storage device is low when the file system is abnormal, on the basis of the foregoing embodiment, the present embodiment can determine the probability of successful mount by determining whether the file system of the external storage device is abnormal, so as to make a pre-determination before actually performing mount operation, and do not perform mount operation when the file system is abnormal, thereby saving resources and improving mount efficiency.

In addition, when the external storage device management module determines that the file system of the external storage device is abnormal and sets the mount state identifier of the external storage device as the mount-impossible identifier, the mount operation may not be executed, but the mount-impossible identifier is sent to the storage management service module, so that the storage management service module may broadcast the corresponding mount result. Specifically, please refer to fig. 6, which illustrates a mount processing method provided in an embodiment of the present application, and specifically, the method includes: s601 to S610.

In this embodiment, when the current mount is completed, a mount completion instruction is sent to the storage management service module, where the mount completion instruction includes the mount state identifier, so that the storage management service module can obtain the mount state identifier of the external storage device when receiving the mount completion instruction.

In this embodiment, if the external storage device management module determines that the file system of the external storage device is abnormal, the mount state identifier of the external storage device is set as the mount-disabled identifier, and the current mount is completed at this time; if the mounting result is not abnormal, the mounting result is obtained, the mounting state identification is set according to the mounting result, and the current mounting is also completed. When the file system is abnormal, the external storage device management module still sends the mounting-incapable identifier to the storage management service module, so that the storage management service module can broadcast the corresponding mounting result when the external storage device is mounted every time, and even if the mounting operation is not executed when the file system is abnormal, the corresponding mounting failure is broadcast, so that other application programs can timely know the mounting state of the inserted external storage device.

S610: and the storage management service module broadcasts a mounting result corresponding to the mounting state identifier according to the mounting state identifier.

As an implementation manner, if the mount state identifier is the mount-impossible identifier, the storage management service module broadcasts that the mount fails; if the mounting state identifier is the mounted identifier, the storage management service module broadcasts that the mounting is successful, so that the application program on the system can access the external storage device which is successfully mounted. Specifically, the storage management service module broadcasts the mount result to the system, and the application program may perform a corresponding operation after monitoring the broadcast, for example, the application program for file management may display the external storage device on an interface of the application program when monitoring a broadcast that the mount is successful, and display the external storage device as an exception on the interface of the application program when monitoring a broadcast that the mount is failed.

According to the mount processing method provided by the embodiment, on the basis of the foregoing embodiment, after the external storage device management module detects that the file system of the external storage device is abnormal, mount operation is not executed, unnecessary resource consumption is reduced, and meanwhile, the mount result corresponding to the detected abnormal identifier is still broadcast by the storage management service module by sending the mounting-disabled identifier to the storage management service module, so that other application programs can timely acquire the current mount result, response efficiency is improved, a user can conveniently and timely take measures when mount failure occurs, and user experience is improved.

As an implementation manner, when the detection duration exceeds the preset duration, the external storage device management module may also not interrupt the detection operation, so that the detection operation continues to repair the damaged file system. Specifically, when the file system is damaged too much, the external storage device management module needs to complete the repair of all abnormal file systems, the required time is long and may exceed the preset time, and at this time, the detection operation is not interrupted when the detection time exceeds the preset time, so that the external storage device management module can continue to repair the damaged file system in the external storage device.
