Background
In data storage, data corresponding to one application program is usually stored in a designated path, and each partition in the disk may correspond to data content of a different application program. However, the use frequencies of different application programs are different, and the use frequencies of part of the application programs are very high, so that the calling frequency of data of the application programs is also high, and therefore the erasing frequency of a disk partition where the application programs are located is high, and meanwhile, the erasing frequency of the disk partition where the application programs with lower use frequency are also low, and therefore the problem that the erasing frequencies of different partitions of the disk are inconsistent is caused, and the service life of the disk cannot reach a theoretical value.

Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
FIG. 1 is a flow chart of a data processing method according to an exemplary disclosed embodiment, as shown in FIG. 1, the method comprising the steps of:
s11, blocking a data storage instruction and data to be stored which are sent to a target high-frequency partition through a file system, wherein the target high-frequency partition is a target high-frequency partition corresponding to the file system.
The target high-frequency partition is a partition with higher erasing frequency in a disk, and the disk can be a disk loaded in any equipment such as a vehicle, a mobile terminal, a server device and the like, and can be a disk for storing common data or a disk for bearing an application program and recording data related to the application program.
The data storage instruction for the target high-frequency partition of the magnetic disk can be an instruction that a user directly points to, for example, the user selects a data storage path through a display interface of the magnetic disk, and the storage path is positioned in the target high-frequency partition; the data storage instruction may be an instruction for pointing based on an application program, for example, when it is necessary to store data for an application program whose storage area is located in a target high-frequency partition of a disk, the data storage instruction used for the data storage is a data storage instruction for the target high-frequency partition of the disk.
The data to be stored can be any form of data such as pictures, documents, videos, system files, system logs and the like, and the form of the data stored in the disk is not limited in the disclosure.
The disk comprises at least one file system, and an idle file folder and a file system corresponding to each high-frequency partition are determined; storing directory information and operation functions of the high-frequency partition and the free folder into the file system; the file system is used for blocking a data operation instruction aiming at a high-frequency partition corresponding to the file system, responding to the data operation instruction, and operating the data in the high-frequency partition or an idle folder corresponding to the high-frequency partition based on an operation function corresponding to the data operation instruction, wherein the data operation instruction comprises at least one of a data storage instruction, a data operation instruction and a data display instruction.
As shown in fig. 2, a schematic structure diagram of an operating system is shown in fig. 2, in which a user state and a kernel state interact with a virtual file system through a system call, where a routfs is a file system for executing the methods S11 to S14 in the disclosure, the file system is a stacked file system, is mounted on a high-frequency partition a, and stores paths of partitions such as a low-frequency partition B, C corresponding to the high-frequency partition a, when a user accesses the high-frequency partition a, the virtual file system is called through the system call, and because the file system routfs is mounted on a common file system, the virtual file system transfers a data operation instruction to the file system routfs, and determines a real data path corresponding to the data operation instruction by the file system routfs, and performs a corresponding data operation.
The file system can be mounted when being started, the mounted parameters are the directories of the high-frequency partition and the corresponding target idle folder, after the file system obtains the paths of the directories, path information can be saved through superblocks of the system, and file operation functions and folder operation functions in the high-frequency partition and the low-frequency partition are saved in the superblocks of the file system. And checking whether a record file exists in the low-frequency partition where the target free folder is located, if so, loading the file operation record recorded in the record file, and if not, newly building the record file in the low-frequency partition. When data call is carried out, corresponding data and corresponding operation interfaces are obtained through interfaces of the file system, and the data are operated through stored operation functions. S12, determining a target idle folder corresponding to the high-frequency partition.
The target free folder is located in a low frequency partition of the disk. The erasing frequency of the high-frequency partition is higher than that of the low-frequency partition.
It should be noted that, the distinction between the high-frequency partition and the low-frequency partition is determined based on the erasing frequency of each partition at the time when the correspondence between the high-frequency partition and the free folder is established, after the subsequent operations such as data storage and recall, the erasing frequency of the low-frequency partition may be higher than or equal to that of the high-frequency partition, in which case, the storing of data into the low-frequency partition may be selectively restricted, or the corresponding free folder may be redetermined for the high-frequency partition in other low-frequency partitions.
In one possible implementation manner, one high-frequency partition may also correspond to a plurality of target idle folders, where the target idle folders may be located in different low-frequency partitions, different subdirectories of the high-frequency partition may correspond to different idle folders in different low-frequency partitions, may also correspond to different idle folders in the same low-frequency partition, may also correspond to the same idle folder in the same low-frequency partition, and may determine, through a data storage instruction, a target subdirectory of data to be stored in the target high-frequency partition, and determine a target idle folder corresponding to the target subdirectory. For example, the target high-frequency partition a has subdirectories A1, A2, A3, where A1 corresponds to the free folder B1 in the low-frequency partition B, A2 corresponds to the free folder C1 in the low-frequency partition C, A3 corresponds to the free folder C2 in the low-frequency partition C, and after an instruction to store data into the subdirectory A2 is acquired, it may be determined that the target free folder corresponding to the target high-frequency partition is the free folder C1 in the low-frequency partition C.
S13, storing the data to be stored into the target idle folder.
Because the target free folder is positioned in the low-frequency partition with lower disk erasing frequency, the file to be stored in the target high-frequency partition can be stored in the target free folder so as to reduce the disk consumption of the target high-frequency partition and transfer the disk consumption of the target high-frequency partition into the low-frequency partition.
Considering that the disk loss of the low frequency partition will rise after the data to be stored is stored in the target free folder for a plurality of times, or the remaining capacity of the target free folder may be insufficient, in one possible embodiment, it may be determined whether to store the data in the target free folder according to the remaining capacity of the target free folder, and in another possible embodiment, it may be determined whether to store the data in the target free folder according to the erasing frequency of the low frequency partition.
The remaining capacity of the target idle folder can be determined, whether the remaining capacity of the target idle folder meets a preset capacity condition or not is judged, the data to be stored is stored in the target idle folder under the condition that the remaining capacity of the target idle folder meets the preset capacity condition, and the data to be stored is stored in the target high-frequency partition under the condition that the remaining capacity of the target idle folder does not meet the preset capacity condition.
The remaining capacity of the target free folder is a difference between the rated capacity and the occupied capacity of the target folder, and the rated capacity may be a pre-allocated capacity, or the rated capacity may be a remaining capacity of a low frequency partition, which the present disclosure does not limit. For example, the total capacity of the low-frequency partition is 1024MB, the other files occupy 24MB, the rated capacity may be 1000MB (i.e. the remaining capacity of the low-frequency partition), or may be pre-allocated 500MB, and in the subsequent use, the capacity occupied by the other files of the low-frequency partition becomes 124MB, and the rated capacity may be 900MB (i.e. the remaining capacity of the low-frequency partition), or may be pre-allocated 500MB.
The preset capacity condition may mean that the remaining capacity reaches a preset capacity threshold, or that the ratio (i.e., occupancy rate) of the remaining capacity of the target free folder to the total capacity is less than a preset occupancy rate threshold, or that the remaining capacity is higher than the amount of data to be stored, or that the occupancy rate of the target free folder and the occupancy rate of the target high-frequency partition meet a size condition.
For example, if the preset capacity condition is that the residual capacity reaches 1G, storing the file to be stored into the target frequency partition instead of the target free folder in the case that the residual capacity is only 900 MB; the preset capacity condition is that the occupancy rate is less than 80%, if the rated capacity is 1000MB and the occupied capacity is 900MB, the occupancy rate of the target free folder reaches 90%, and the file to be stored is stored in the target frequency partition instead of the target free folder; the preset capacity condition may be that the occupancy rate of the target free folder is lower than the occupancy rate of the target high-frequency partition, and then the file to be stored is stored in the target high-frequency partition instead of the target free folder under the condition that the occupancy rate of the target free folder is 80% and the occupancy rate of the target high-frequency partition is 40%.
The erasing frequency of the low-frequency partition can be determined, whether the erasing frequency of the low-frequency partition meets a first erasing condition or not is judged, the data to be stored is stored in the target idle folder under the condition that the erasing frequency of the low-frequency partition meets the first erasing condition, and the data to be stored is stored in the target high-frequency partition under the condition that the erasing frequency of the low-frequency partition does not meet the first erasing condition.
The first erasing condition may be that the erasing frequency of the low frequency partition is lower than a preset erasing frequency threshold value, or is lower than or equal to a preset erasing frequency threshold value.
Or determining the erasing frequency of the target high-frequency partition and the erasing frequency of the low-frequency partition, and judging whether the ratio or the difference between the erasing frequency of the target high-frequency partition and the erasing frequency of the low-frequency partition meets a second erasing condition, storing the data to be stored in the target free folder when the ratio or the difference between the erasing frequency of the target high-frequency partition and the erasing frequency of the low-frequency partition meets the second erasing condition, and storing the data to be stored in the target high-frequency partition when the ratio or the difference between the erasing frequency of the target high-frequency partition and the erasing frequency of the low-frequency partition does not meet the second erasing condition.
For example, the second erasing condition may be that a ratio of an erasing frequency of the target frequency division and an erasing frequency of the low frequency division is greater than a ratio threshold, or the second erasing condition may be that a difference between the erasing frequency of the target frequency division and the erasing frequency of the low frequency division is greater than a difference threshold. That is, in the case where the erasing frequency of the low frequency division increases, the storage of files into the low frequency division may be restricted in order to balance the disk consumption of the target frequency division and the low frequency division.
In one possible embodiment, it may be determined whether to store data in the target free folder based on the frequency of erasing the target frequency partition, the frequency of erasing the low frequency partition, and the remaining capacity of the target free folder. The specific storage condition can be adaptively adjusted according to the storage requirement, as an example, the occupancy rate of the target idle folder can be used as a first index, the ratio of the erasing frequencies of the target frequency partition and the low frequency partition can be used as a second index, different weights are given to the first index and the second index according to different storage requirements, and whether to store data in the target frequency partition or store data in the target idle folder is determined based on the sum of the weighted first index and the weighted second index.
The erasing frequency of the target high-frequency partition is determined based on an operation record file of the target high-frequency partition, the erasing frequency of the target free folder is determined based on an operation record file of the target free folder, the operation record file can be a file in the form of a record file, wherein a calling record of a directory where the file is located is recorded, and the calling record can comprise a calling form of data, a calling amount of the data, a calling path of the data and the like. When data writing, data reading and data deleting operations are executed on the target high-frequency partition or the target free folder, the operation times and the data change amount are recorded in an operation record file corresponding to the target high-frequency partition or the target free folder.
It is worth to say that, the data condition of the catalog where the operation record file is located can be checked through the operation record file, and the target idle folder is located in the low-frequency partition, so that the operation record file of the target idle folder can be hidden in the processes of checking, calling and the like of the low-frequency partition, the data operation record in the low-frequency partition is not influenced by the data calling operation in the target idle folder, the record confusion is avoided, and the user can check and call the data of the low-frequency partition more conveniently.
In a possible implementation manner, the data storage instruction further includes a target directory, where the target directory is any subdirectory in the target high-frequency partition, and the data to be stored is stored in a subfolder corresponding to the target directory in the target free folder. Under the condition that the sub-directory corresponding to the target directory does not exist in the target high-frequency partition, the sub-directory corresponding to the target directory can be newly built in the target high-frequency partition, and under the condition that the sub-folder corresponding to the target directory does not exist in the target free folder, the sub-folder corresponding to the target directory can be newly built in the target free folder. For example, the target high-frequency partition is an area a, the target free folder corresponding to the target high-frequency partition is an area B A1 folder, the target directory to be stored with data is/a/c (i.e. directory c in area a directory a), and directory c does not exist in area a directory a, directory c can be newly built in directory a, subfolder a does not exist in area B A1 folder, subfolder a is newly built in the area A1 folder, subfolder c is newly built under subfolder a, and thus the real storage path is/B/A1/a/c.
In one possible implementation manner, acquiring a catalog creation instruction or a catalog deletion instruction for the target frequency partition; creating a catalog corresponding to the catalog creation instruction in the target frequency partition, and creating a catalog corresponding to the catalog creation instruction in the target idle folder; or deleting the catalogue corresponding to the catalogue deleting instruction in the target high-frequency partition, and deleting the catalogue corresponding to the catalogue deleting instruction in the target idle folder.
In this way, subfolders corresponding to the catalogues in the target frequency partition are built in the target free folder, files are classified and stored, so that the files are ordered, and the calling efficiency of the data is improved.
In one possible implementation manner, a data display instruction for the target high-frequency partition may be acquired, where the data display instruction includes a directory to be displayed, determines data to be displayed in the directory to be displayed of the target high-frequency partition and data to be displayed in a subfolder corresponding to the directory to be displayed in the target free folder, merges the data to be displayed in the target high-frequency partition and the data to be displayed in the target free folder, and displays the merged data.
For example, in the case where the directory to be displayed in the data display instruction is/a/c/c 1, all data in the directory c/c1 in the high-frequency partition a may be searched, the target free folder B/a corresponding to the high-frequency partition a may be determined in the low-frequency partition B, all data in the subfolder/B/a/c/c 1 corresponding to the directory c/c1 may be determined, and the data in/a/c/c 1 and/B/a/c/c 1 may be combined and displayed.
It should be noted that, the directory to be displayed may be the largest directory of the target high-frequency partition, for example, the directory to be displayed may be/a, and then the directory to be displayed is the high-frequency partition a, where in this case, the data in the high-frequency partition a and the target free folder corresponding to the high-frequency partition a are combined and displayed.
It should be noted that, the data displaying instruction may be performed based on a selection operation of a user, for example, when the user selects the high-frequency partition a, a directory to be displayed in the data displaying instruction is/a, after displaying all files (including subfolders) corresponding to the directory/a in the target high-frequency partition and the low-frequency partition, the selection operation of the user on the directory/a may be further obtained, and the subdirectory selected by the user is taken as the directory to be displayed. For example, when the user further selects the subdirectory/c in the directory/a, a new data presentation instruction is generated, and the directory to be presented corresponding to the new data presentation instruction is/a/c. The above process of exposing files and obtaining user selection operations may continue to loop until there are no subdirectories that can be further exposed.
In one possible implementation manner, the data to be displayed in the low-frequency partition and the data in the target idle folder may be determined in response to a data display instruction for the low-frequency partition, where the data in the target idle folder is in a hidden state.
Therefore, files corresponding to the target frequency partition stored in the low frequency partition can be hidden, so that the uniformity of data is improved, and the searching and calling of the data by a user are facilitated.
After the data is written, the data may be operated on based on different data operation instructions.
In one possible implementation manner, a data processing instruction for the target high-frequency partition may be acquired, target data to be processed is searched in the target high-frequency partition and the target idle folder, and a data processing operation is performed on the target data based on the type of the data processing instruction, wherein the data processing operation includes at least one of an opening operation, a modifying operation and a deleting operation. After processing the data, it may be determined whether to store the processed target data in the target free folder based on the remaining capacity and/or the erasing frequency of the target free folder. That is, when creating the target data, it may be determined whether to store the target data in the target frequency partition or the target free folder based on the data storage rule of step S13, which will not be described herein.
For example, the data operation instruction may be an openfile instruction, the system may call a search interface to search target data in the target high-frequency partition and the target idle folder, if the target data is searched, call the underlying file system to open a file corresponding to the target data, and if the instruction includes a "truncate" instruction, delete the target data and create new target data in the target high-frequency partition or the target idle folder; when the target data is not found, if a "create" instruction exists in the instructions, the target data may be created in the target high-frequency partition or the target free folder.
The data operation instruction may be a read instruction, and may determine a storage location of the target data, and call a file system interface where the target data is located to read the data.
The data operation instruction can be a write instruction, so that the storage position of target data can be determined, a file system interface where the target data is positioned is called, the data is modified, and a record of file calling is stored in a record file corresponding to the storage position; meanwhile, a close interface of the target file can be called, the target data is closed based on closing operation of a user, and an opened record of the file is stored in the record file.
It should be noted that, there may be a data and a target high-frequency partition and a target idle folder, and there is no obvious advantage or disadvantage in setting the order of searching for the data and the target idle folder, so the present disclosure does not limit the searching order of the target high-frequency partition and the target idle folder when searching for data. However, since data may also exist in the cache area and not yet stored in a specific directory, the data to be processed may be searched in the cache area of the disk before searching the target frequency partition or the target free folder, and in the case that the data to be processed does not exist in the cache area of the disk, the data to be processed may be searched in the target frequency partition and the target free folder.
As shown in fig. 3, in the view of the user, the folder with path of/a/data/tmp/test is included in the high-frequency partition a, the file with path of/a/data/tmp/test 1, the file with path of/a/data/tmp/test 2, and the file with path of/a/data/tmp/test 3 are present below, and the folder with path of/a/data/tmp/test 1 is included in the high-frequency partition a, the folder with path of/a/data/tmp/test 1 is included in the low-frequency partition B, the folder with path of/B/a/data/tmp/test 2 is included in the low-frequency partition B, and the file with path of/B/a/tmp/test 3 is included in the real disk. Thus, from a user perspective, the files in the high frequency partition are unified and there is no use experience in which the storage locations are distributed among the various partitions of the disk.
Through the technical scheme, at least the following technical effects can be achieved:
the data to be stored in the high-frequency partition can be stored in the target idle folder positioned in the low-frequency partition, the effect of balancing the erasing frequency of each partition of the disk is achieved by transferring the data carried by the high-frequency partition to the low-frequency partition, and the storage positions of the data are more regular and more beneficial to data calling because the high-frequency partition and the target idle folder have a corresponding relationship.
