In the present application, if any file in the file system is opened by a process in the electronic device mentioned in fig. 1 to 6, that is, if the file system of the electronic device is occupied, the file system fails, in order to repair the occupied file system when the operating system is running, and improve the use experience of the user, the present application provides a file system repair method and a terminal device.
In the present application, the file system repairing method is applied to an electronic device deployed on a file system, where the file system is a method and a data structure for an operating system to definitely store files on a device or a partition, that is, a method for organizing files on a storage device. The software mechanism responsible for managing and storing file information in an operating system is called a file management system, which is called a file system for short. In some embodiments, the electronic device may be a television, a cell phone, or the like.
In this application, the file system repair process of the electronic device may be: when an operating system in the electronic equipment detects that an error occurs in a file system, the file system is identified, a first partition with the error occurs in the file system is identified, a process is traversed, a first file opened in the first partition is determined, a target process for opening the first file is determined, the target process is frozen, the operating system cannot schedule the target process, the first file is copied into a second partition and used as a second file of the second partition, the target process is controlled to open the second file, and the target process is controlled to release the first file. And unloading the file system after the first opened file does not exist in the first partition, and repairing the file system of the first partition.
Specifically, in the present application, a storage device such as a disk, a solid state disk, an eMMC, and the like may be divided into one or more partitions, where each partition may select whether to use a file system, and the file systems used by different partitions may be the same or different. When the operating system is running or the file system is mounted, if the first partition with the error in the file system is identified, that is, when the file system of the first partition is identified to have the error, the file system of the first partition needs to be repaired, but because processes such as application software for opening files in the first partition exist in the electronic device, if the file system of the first partition is directly repaired, the files opened by the application software are closed, and the use experience of a user is affected, therefore, in the application, after the first partition with the error in the file system is identified, the first files opened in the first partition are acquired, wherein one or more files may be opened in the first partition, and any opened file, that is, the first files are described.
After the first file opened in the first partition is obtained, the first file is copied to the second partition, and the first partition is repaired. The second partition may be located in a different storage device than the first partition, and a file system of the second partition may be the same as or different from a file system of the first partition.
In this application, the first partition and the second partition mentioned in the above embodiments may use the same file system, or may use different file systems.
In the present application, if a first partition in which an error occurs in a file system is identified, when an opened first file in the first partition is acquired, the opened first file may not exist in the first partition. I.e. there is no process in the electronic device that opens files in the first partition, the file system of the first partition may be unloaded. At this time, if the first partition is directly repaired, no influence is brought to the working process in the electronic device, and at this time, the first partition can be directly repaired.
In this application, the repair process of the first partition is in the prior art, where the process of repairing the first partition may be reconstructing a structure of a file system of the first partition, or recovering a file index data block through a log to achieve file system repair, or repairing the first partition by using a repair tool provided by the file system itself.
In the embodiment of the application, when the file system of the first partition fails, the first file of the file system of the first partition opened by the target process is copied to the file system of the second partition, and then the target process is controlled to open the second file copied in the file system of the second partition.
In the embodiment of the invention, after the first partition is identified to have errors, a first file opened in the first partition is determined, a running process in the electronic equipment is traversed, a target process for opening the first file is identified, and the target process is frozen, so that the target process is not operated any more, namely the target process is controlled to not modify the first file any more. And modifying the process state of the target process to be frozen, so that an operating system of the electronic equipment does not schedule the target process any more, and the target process is prevented from continuing to use the first file. And then determining the storage position of the first file in the first partition according to the first index of the first file recorded in the target process. Specifically, in the present application, the storage location of the first file in the first partition, the current browsed address of the first file, and the authority of the first file are recorded in the first index, where the authority of the first file includes account information of an owner of the first file and account information that can edit the first file.
After identifying the target process of opening the first file, the storage position of the first file in the first partition may be determined according to the first index of the first file recorded in the target process, and then the first file is acquired from the first partition.
In this application, after identifying the target process of opening the first file in the first partition, in order to avoid modifying the first file during copying the first file to the second partition, the target process may be frozen first, so that the operating system of the electronic device does not schedule the target process any more.
In the present application, after the first file opened in the first partition is acquired, since the current location where the first file is browsed is also stored in the first index corresponding to the first file, the current target location where the first file is browsed may be determined according to the first index.
In addition, after the first file is copied into the second partition, the file copied into the second partition is used as a second file, a second index corresponding to the second file is generated, the second index also carries the browsed target position identical to the first index, and the second index is stored in the target process.
In this application, in the application process of the electronic device, a situation that one or more processes open the same file may occur, and in particular, a situation that one or more processes open a first file may occur. And when the electronic device freezes the processes, all the processes cannot be frozen at the same time, but each process is frozen in turn, which also results in that when a first file is opened by a plurality of processes including a target process, after the target process is frozen, other processes which open the first file and are not frozen except the target process may exist to modify the content of the first file, so that the content of the first file is changed. At this time, in the present application, the operating system of the electronic device may replace the second file of the second partition with the changed first file.
In the application, after the first file is copied to the second partition, the file in the second partition is used as the second file, and meanwhile, a second index corresponding to the second file is generated, and the second index carries the storage position of the second file in the second partition. The file that allows the target process to open is no longer the first file in the first partition, but rather the second file of the second partition.
In addition, in the application, the second index also carries a target position to which the second file is browsed, wherein the target position to which the second file is browsed is the same as the browsed position of the first file recorded in the first index of the first file. The target process can be controlled to open the second file, and the target browsing position of the opened second file is the same as the browsing position of the first file, so that the target process does not need to manually adjust the browsing position after replacing the file, and the use experience of the user is improved.
Specifically, in this application, the target process may be controlled to open the second file according to the storage position of the second file in the second partition carried in the second index, and the browsing position of the second file opened by the target process may be located to the target position according to the target browsing position to which the second file carried in the second index is browsed.
In the application, after the file system repair of the first partition is completed, the target process for opening the second file is controlled to not open the second file any more, but to reopen the first file.
In order to accurately and quickly find the target process for opening the second file, in the application, after the target process is controlled to open the second file, the target process is marked. When the first partition repair is identified to be completed, the operating system of the electronic device can determine the target process for opening the second file by identifying the target process carrying the mark.
After identifying the target process with the tag, in the present application, after the target process opens the second file, the target process may not be frozen, and thus, after identifying the target process with the tag, the target process may be frozen. Specifically, in the present application, after the target process with the mark is identified, the target process with the mark is frozen, if the target process with the mark is already frozen, the operation of freezing the target process with the mark is regarded as invalid, and the target process with the mark is still in a frozen state; if the target process carrying the tag has not been successfully frozen before, it is frozen.
In the application, after the target process is frozen, the second file of the second partition is adopted to replace the first file of the first partition, and the target process with the mark is controlled to open the replaced first file in the first partition. Specifically, in this application, when repairing the file system of the first partition, the content of the first file in the first partition may be changed, for example, the first file in the first partition may be formatted, etc. Therefore, after the repair to the first partition is completed, the second file of the second partition is used to replace the first file in the first partition, and the target process carrying the mark is controlled to open the replaced first file in the first partition.
In the present application, after the target process with the flag is controlled to open the replaced first file in the first partition. Because the file system of the first partition has been repaired, and the file opened by the target process with the mark is no longer the second file of the second partition, but is the first file replaced in the first partition, at this time, the target process with the mark can be thawed, that is, the target process with the mark is awakened, so that the operation of the electronic device can continue to schedule the target process with the mark.
Among them, there are many methods for freezing a target process, and the technical means commonly used at present are generally: and the control operating system adds the target process into a frozen list, freezes the target process, and releases the target process from the frozen list if the target process needs to be thawed, namely wakes the target process. In addition, the operating system also records the state of the target process, such as running, ready, sleep capable of being interrupted, sleep incapable of being interrupted, and the like, and when the target process is frozen, the target process is not scheduled by the operating system to enter the running state.
In this application, the most common file system is a magnetic disk, and also a solid state disk. The software mechanism responsible for managing and storing file information in an operating system is called a file management system, which is called a file system for short. The file system is responsible for creating files for users, storing, reading out, modifying, dumping files, controlling access to files, withdrawing files when users are no longer using, etc. In an electronic device, one or more file systems may exist, and at the same time, a file system may be partitioned into one or more partitions. The partition of the file system can be set by a user according to the requirements of the user.
