Description

Technical Field

[0001] The present application relates to the technical field of system image burning, and in particular to a system image burning method and device. Background Art

[0002] With the rapid development of information technology, the deployment demand for operating systems and applications is increasing. System image burning is the process of packaging the pre-configured operating system, applications and their related data into an image file and writing it to the target medium where it needs to be stored. This process is widely used in the fields of large-scale deployment of computer equipment, development and testing of embedded systems, and initial configuration of servers. An efficient and reliable image burning method is of great significance for improving deployment efficiency and ensuring system consistency.

[0003] At present, the traditional system image burning method usually uses binary image files and requires that the capacity of the burning target medium is at least equal to the size of the image file. If the capacity of the target medium is larger than the size of the image file, there will be some capacity left after burning. This requires manual adjustment of the original partition size to make full use of the space, resulting in the image file burning process being inflexible and inefficient. Binary burning also results in low transmission efficiency, which in turn limits the efficiency and reliability of system image burning. These problems are particularly prominent in scenarios of large-scale deployment and frequent updates. Summary of the invention

[0004] In view of the above problems, the present application provides a system image burning method and device, the main purpose of which is to make the image file burning process flexible and intelligent, so as to improve the efficiency and reliability of system image burning.

[0005] In order to solve the above technical problems, this application proposes the following solutions:

[0006] In a first aspect, the present application provides a system image burning method, the method comprising:

[0007] When it is detected that the target medium is mounted on the burning host, the target medium is intelligently partitioned according to the use requirements to obtain a plurality of preset file partitions corresponding to the target medium, and a file type and a transmission form corresponding to each preset file partition, wherein the transmission form includes file copying and compressed package decompression;

[0008] Parsing the image file to be burned in the burning host, and extracting the file content contained in the image file to be burned;

[0009] A target file partition corresponding to the file content is determined in the plurality of preset file partitions according to the file type, and the file content is burned into the target file partition according to the transmission form corresponding to the target file partition.

[0010] In a second aspect, the present application provides a system image burning device, the device comprising:

[0011] A partitioning unit is used to intelligently partition the target medium according to usage requirements after detecting that the target medium is mounted on the burning host, and obtain a plurality of preset file partitions corresponding to the target medium, and a file type and a transmission form corresponding to each preset file partition, wherein the transmission form includes file copying and compressed package decompression;

[0012] The parsing and extracting unit is used to parse the image file to be burned in the burning host and extract the file content contained in the image file to be burned;

[0013] The first burning unit is used to determine the target file partition corresponding to the file content obtained by the parsing and extraction unit in the multiple preset file partitions according to the file type obtained by the partitioning unit, and burn the file content into the target file partition according to the transmission form corresponding to the target file partition.

[0014] In order to achieve the above-mentioned purpose, according to the third aspect of the present application, a storage medium is provided, wherein the storage medium includes a stored program, wherein when the program is running, the device where the storage medium is located is controlled to execute the system image burning method of the above-mentioned first aspect.

[0015] In order to achieve the above-mentioned purpose, according to a fourth aspect of the present application, a processor is provided, wherein the processor is used to run a program, wherein when the program is running, the system image burning method of the above-mentioned first aspect is executed.

[0016] By means of the above technical scheme, a system image burning method and device provided by the present application is that when it is necessary to burn a system image file, after detecting that a target medium is mounted to a burning host, the target medium is intelligently partitioned according to usage requirements to obtain multiple preset file partitions corresponding to the target medium, and the file type and transmission form corresponding to each preset file partition, the transmission form includes file copying and compressed package decompression, parsing the image file to be burned in the burning host, and extracting the file content contained in the image file to be burned, determining the target file partition corresponding to the file content in multiple preset file partitions according to the file type, and burning the file content to the target file partition according to the transmission form corresponding to the target file partition. By the technical solution provided by the present application, the target medium can be automatically partitioned intelligently according to the use requirements before burning, and the file type and transmission mode of each preset file partition after the partition are defined. After parsing the file content of the image file, the target file partition that the file content is most suitable for storage can be automatically matched and determined according to the file type, and the file content is burned according to the transmission mode of the target file partition, which not only avoids manual adjustment of the partition after burning, but also ensures that the partition is more in line with the use requirements, improves flexibility and intelligence, and enables the system to use storage resources more effectively and avoid unnecessary space waste. In addition, the most suitable transmission form (such as file copy or compressed package decompression) can be determined according to the file type, which not only effectively improves the transmission efficiency, but also avoids the mismatch between the file type and the partition, further improving the success rate and reliability of burning. That is, the intelligent level of system image burning is significantly improved, the flexibility of the partition scheme and the efficiency of file transmission are ensured, thereby greatly improving the overall efficiency and reliability of system deployment and update.

[0023] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0024] At present, the traditional system image burning method usually uses binary image files and requires that the capacity of the burning target medium is at least equal to the size of the image file. If the capacity of the target medium is larger than the size of the image file, there will be some capacity left after burning. This requires manual adjustment of the original partition size to make full use of the space, especially for the Rootfs partition, which makes the image file burning process not flexible and intelligent enough. In addition, binary burning will also make the transmission efficiency low, which in turn limits the efficiency and reliability of system image burning. These problems are particularly prominent in scenarios of large-scale deployment and frequent updates.

[0025] After research, the inventor found that the target medium can be intelligently partitioned according to the usage requirements such as purpose and scenario before burning, and the file type and transmission mode corresponding to each preset file partition can be defined, where the file types include ext3, xfs, btrfs, etc., and the transmission mode includes file copying, compressed package decompression, etc. After parsing and extracting the file content in the image file, the target file partition can be determined according to the file type, and then burned according to the transmission form of the target file partition. In this way, not only can the manual adjustment of the partition after burning be avoided, but also the problem of low transmission efficiency caused by binary burning is avoided, that is, the intelligent level of system image burning is significantly improved, the flexibility of the partition scheme and the efficiency of file transmission are ensured, thereby greatly improving the overall efficiency and reliability of system deployment and update.

[0026] Based on the above considerations, the embodiment of the present application provides a system image burning method, through which the image file burning process can be made flexible and intelligent, so as to improve the efficiency and reliability of system image burning. The specific execution steps are as follows: Figure 1 As shown, including:

[0027] 101. When it is detected that the target medium is mounted on the burning host, the target medium is intelligently partitioned according to the use requirements to obtain multiple preset file partitions corresponding to the target medium, and the file type and transmission form corresponding to each preset file partition.

[0028] It should be noted that the execution subject of this embodiment is a burning host, and the target medium includes but is not limited to a HDD, an SSD, a USB drive, etc.

[0029] In this step, the usage requirements are used to characterize the user's specific use of the target medium. For example, the user can select preset uses such as "office", "development" or "server", and the user's information about the use can be collected through the user interface or configuration file. Due to different uses, the storage capacity allocation for the target medium is also different. For example, office use: a larger Home partition, a smaller Root partition, and the use of the ext4 file system; development use: a larger Root partition to accommodate development tools, a medium-sized Home partition, and support for ext4 or xfs file systems; server use: a larger Var partition for logs and caches, a smaller Tmp partition, and the use of ext4 or btrfs file systems. Therefore, after determining the usage requirements, a specific partition strategy template can be pre-set for each usage requirement based on the specific usage information. These templates should cover different types of file systems, as well as the recommended number of partitions, capacity allocation, and content transmission forms. By finding the partition strategy template corresponding to the usage requirements and intelligently partitioning the target medium according to the partition strategy template, the preset file partitions obtained by the target medium after intelligent partitioning meet the user's usage requirements, that is, they meet the user's specific purposes. The partition strategy template may include the number of partitions, the capacity of the partition, the file type corresponding to the partition (such as ext3, xfs, btrfs, etc.) and the transmission form, wherein the transmission form includes file copying and compressed package decompression. In addition, a real-time custom demand configuration template may also be set, which also includes the number of partitions, the capacity of the partition, the file type corresponding to the partition (such as ext3, xfs, btrfs, etc.) and the transmission form. The user defines how to intelligently partition by entering specific parameters in the custom demand configuration template.

[0030] When setting the partition capacity, some redundant space is usually added on the basis of ensuring the minimum necessary space required for the file type to fully meet its resource requirements and ensure that the space of each preset file partition is large enough, thereby improving the reliability of burning.

[0031] By intelligently partitioning the target medium, a plurality of preset file partitions corresponding to the target medium and the file type and transmission form corresponding to each preset file partition are obtained. The file partitions include but are not limited to Boot partition, Rootfs partition, Swap partition, Var partition, Tmp partition and Home partition, etc. Each preset file partition is mounted to the burning host to facilitate the burning operation of step 103.

[0032] 102. Parse the image file to be burned in the burning host, and extract the file content contained in the image file to be burned.

[0033] In this step, first determine the storage location of the image file to be burned, which can be achieved by user specification or system default settings. Parse the internal structure of the image file, identify different types of files and their metadata (such as file name, size, permissions, etc.), and for image files in the form of compressed packages, the system will first decompress and then parse. Extract all file contents that need to be burned from the parsed image file. This process includes not only the data of the file itself, but also the attribute information of the file (such as timestamp, permissions, etc.) to ensure that the file can be completely restored to the target medium. Classify the extracted files according to the content and extension of the file so that they can accurately match the appropriate target file partition in step 103.

[0034] 103. Determine a target file partition corresponding to the file content from among a plurality of preset file partitions according to the file type, and burn the file content into the target file partition according to a transmission format corresponding to the target file partition.

[0035] In this step, since each preset file partition has defined its corresponding file type and transfer form, the file content of each type can be matched to the most appropriate preset file partition, i.e., the target file partition, by using the file type and the classification result when extracting the file content. For example, the operating system files will be placed in the Boot partition, the application files will be placed in the Rootfs partition, and the multimedia files will be placed in the Data partition, etc.

[0036] For each type of file content, the most appropriate transmission form is selected according to the corresponding target file partition, and the file content is written to the corresponding target file partition according to the selected transmission form. For example, the Boot content is copied to the Boot file partition of the target medium in the form of a file copy, and the Rootfs content is decompressed to the Rootfs file partition of the target medium in the form of a compressed package. That is, files that occupy less resources can be directly copied to the target location using a file copy, while files that occupy more resources are compressed first and then decompressed after transmission to save space and improve efficiency. In addition, during the burning process, data corruption can be prevented by verification and checking. After the burning is completed, the burning results can also be confirmed to ensure that all file contents of the image file to be burned are correctly written to the target partition. If there are any problems, a detailed error report can be generated and solutions can be provided.

[0037] Based on the above Figure 1 It can be seen from the implementation method that, through the above technical scheme, a system image burning method provided by the present application is that when it is necessary to burn the system image file, when it is detected that the target medium is mounted to the burning host, the target medium is intelligently partitioned according to the usage requirements to obtain multiple preset file partitions corresponding to the target medium, and the file type and transmission form corresponding to each preset file partition, the transmission form includes file copying and compressed package decompression, parsing the image file to be burned in the burning host, and extracting the file content contained in the image file to be burned, determining the target file partition corresponding to the file content in multiple preset file partitions according to the file type, and burning the file content to the target file partition according to the transmission form corresponding to the target file partition. By the technical solution provided by the present application, the target medium can be automatically partitioned intelligently according to the use requirements before burning, and the file type and transmission mode of each preset file partition after the partition are defined. After parsing the file content of the image file, the target file partition that the file content is most suitable for storage can be automatically matched and determined according to the file type, and the file content is burned according to the transmission mode of the target file partition, which not only avoids manual adjustment of the partition after burning, but also ensures that the partition is more in line with the use requirements, improves flexibility and intelligence, and enables the system to use storage resources more effectively and avoid unnecessary space waste. In addition, the most suitable transmission form (such as file copy or compressed package decompression) can be determined according to the file type, which not only effectively improves the transmission efficiency, but also avoids the mismatch between the file type and the partition, further improving the success rate and reliability of burning. That is, the intelligent level of system image burning is significantly improved, the flexibility of the partition scheme and the efficiency of file transmission are ensured, thereby greatly improving the overall efficiency and reliability of system deployment and update.

[0038] Further, the preferred embodiment of the present application is in the above Figure 1 Based on this, a detailed description of the system image burning process is given. The specific steps are as follows Figure 2 As shown, including:

[0039] 201. Determine a partition policy template corresponding to the target medium based on usage requirements.

[0040] Among them, one usage requirement corresponds to one partition strategy template, and the partition strategy template includes the number of partitions, the capacity of the partition, the file type corresponding to the partition, and the transmission format corresponding to the partition.

[0041] In this step, specific usage requirements are collected in advance through the user interface or predefined configuration files. Including but not limited to: operating system type (such as Linux, Windows), application requirements (such as database server, Web server), storage capacity allocation (such as Boot partition size, Rootfs partition size, Home partition size, etc.), file system type (such as ext3, xfs, btrfs, etc.). According to the collected usage requirements, a most suitable partition strategy template is selected from the preset partition strategy library, and a corresponding relationship between the partition strategy template and the usage requirements is established, that is, each usage requirement corresponds to a specific partition strategy template, and the following contents are specified in detail in the partition strategy template: number of partitions: the total number of partitions to be created; partition capacity: the specific capacity size of each partition; file type corresponding to the partition: the file system type that each partition should use (such as ext4, XFS, btrfs); transmission format corresponding to the partition: the transmission form that each partition should use (such as file copy, compressed package decompression). It should be noted that if the partition preset template in the partition strategy library cannot fully meet the specific requirements, the user can further customize the partition preset template. For example, users can resize certain partitions or change the file system type.

[0042] 202. Determine whether the sum of the capacities corresponding to the partition capacities in the partition strategy template is less than or equal to the total capacity of the target medium.

[0043] Normally, the target medium has versions with different capacity sizes. Therefore, in order to enable the partition strategy template to be applied to target media of different capacities, to achieve intelligent partitioning that meets usage requirements and ensure the optimality of the partition. In this step, the sum of the capacities corresponding to the partition capacities in the partition strategy template can be compared with the total capacity of the target medium to ensure that all preset file partitions can be accommodated on the physical storage resources. Specifically, the sum of the capacities of all partitions in the selected partition strategy template can be calculated, that is, each partition in the template is traversed, and the specified capacity values ​​are accumulated, and the calculated sum of the partition capacities is compared with the actual total capacity of the target medium. If the sum of the capacities is less than or equal to the total capacity of the target medium, step 203 is executed, otherwise the adjustment step is entered, that is, step 204 is executed.

[0044] 203. Intelligently partition the target medium according to the partition strategy template to obtain multiple preset file partitions, and the file type and transmission form corresponding to each preset file partition.

[0045] In this step, the total capacity of the target medium is greater than the sum of the capacities corresponding to the partition capacities in the partition strategy template, which means that the smart partition is not limited by the total capacity of the target medium. At this time, the target medium can be partitioned according to the selected partition strategy template. Specifically, it includes creating a specified number of partitions and setting the corresponding capacity size, file system type and transmission form for each partition. At the same time, the partition information is saved to a log file or configuration file so that the information can be accurately referenced in subsequent steps. This includes the identifier of each partition (such as / dev / sdb1), file system type (such as ext4), transmission form (such as file copy), etc.

[0046] 204. Adjust the partition capacity in the partition strategy template according to the total capacity of the target medium, and intelligently partition the target medium according to the adjusted partition strategy template to obtain multiple preset file partitions, as well as the file type and transmission mode corresponding to each preset file partition.

[0047] In this step, the total capacity of the target medium is less than the sum of the capacities corresponding to the partition capacities in the partition strategy template, which means that the intelligent partition is limited by the total capacity of the target medium. At this time, the partition capacity in the partition strategy template needs to be adjusted so that the final intelligent partition fits the total capacity of the target medium. Specifically, a priority can be set in advance for each preset file partition, and the partition capacity of the preset file partition with a low priority can be reduced according to the total capacity of the target medium, so that the sum of the capacity of the partition capacity is less than or equal to the total capacity of the target medium. Categories can also be defined in advance for each preset file partition, including key partitions and non-key partitions, and the partition capacity of non-key partitions can be reduced according to the total capacity of the target medium, so that the sum of the capacity of the partition capacity is less than or equal to the total capacity of the target medium. It is also possible to pre-define which partitions are deletable, directly delete the deletable partitions, and divide the partition capacity of the deletable partition into other non-deletable partitions or partitions with expansion requirements in proportion, or divide it into partitions with expansion requirements according to pre-defined directional labels. This embodiment does not limit this.

[0048] With respect to the description of adjusting the partition capacity in the partition strategy template in comparison with the total capacity of the target medium, the specific implementation process is: calculating the capacity difference between the total capacity of the target medium and the sum of the capacities corresponding to the partition capacities; reducing the partition capacity of the non-critical partition according to a preset gradient or preset ratio based on the capacity difference, until the sum of the capacities corresponding to the partition capacities in the adjusted partition strategy template is less than or equal to the total capacity of the target medium.

[0049] Among them, the partition strategy template also includes partition categories, and the partition categories include key partitions and non-key partitions. Key partitions specifically refer to preset file partitions that are necessary for system startup and basic function operation, which can be Boot partitions, Rootfs partitions, etc., to ensure that they retain enough space to meet the basic requirements of system startup and operation. Only in extreme cases, the capacity of key partitions is appropriately reduced, but the minimum necessary space must still be guaranteed. Non-key partitions specifically refer to preset file partitions that are not necessary for system startup and basic function operation, which can be Swap partitions, Var partitions, Tmp partitions, Home partitions, etc. Specifically, the capacity difference between the total capacity of the target medium and the sum of the capacities of all partitions in the partition strategy template is calculated, and the capacity difference determines the extent of adjustment required. According to the capacity difference, the non-key partition is reduced, and the reduction method can gradually reduce the partition capacity of the non-key partition according to a preset gradient or a preset ratio, until the sum of the capacities of all partitions in the adjusted partition strategy template is less than or equal to the total capacity of the target medium, and the adjusted partition strategy template is obtained. After adjustment, the adjustment information is saved to a log file or a configuration file so that the information can be accurately referenced in subsequent steps. This includes the number of partitions, the original capacity of each partition, the adjusted capacity, the file system type (such as ext4), the transfer method (such as file copy), etc.

[0050] Through steps 201-204, an automated and intelligent partitioning process can be achieved, reducing manual intervention, avoiding errors that may occur in manual partition adjustment, and improving the accuracy and efficiency of partitioning. The optimal partitioning scheme is dynamically generated based on specific usage requirements to ensure that it can adapt to different application scenarios and hardware configurations, thereby enhancing flexibility and applicability.

[0051] 205. Parse the image file to be burned in the burning host, and extract the file content contained in the image file to be burned.

[0052] This step is combined with the description of step 102 in the above method, and the same contents are not repeated here.

[0053] 206. Get the historical mount records of the burning host.

[0054] It should be noted that, since the target medium may not be burned for the first time for the burning host, as can be seen from steps 201-204, when it is detected that the target medium is mounted to the burning host, the system will perform intelligent partitioning on it, and for the target medium mounted for the second time, under the premise that its use demand does not change, it does not need to be re-intelligently partitioned, and only needs to use the preset file partition obtained by intelligently partitioning the target medium according to the use demand after it is first mounted to the burning host. Therefore, in this step, a built-in or externally stored mount record database can be accessed, which records all target media and related information that have been mounted on the burning host, and the historical mount record of the burning host is extracted therefrom, and the historical mount record includes but is not limited to: the device identifier of the target medium, the mount time, the mount point (such as / mnt / sdX), the partition information (such as the partition identifier, the file system type) and the burning operation result (success or failure), etc. The historical mounting records are traversed. If the existence of the target medium is detected therein, it means that the target medium is mounted for the first time, and step 207 is executed at this time. Otherwise, it means that the target medium is mounted for the second time, and steps 208-211 are executed at this time.

[0055] 207. Intelligently partition the target medium according to usage requirements to obtain multiple preset file partitions corresponding to the target medium and a transmission format corresponding to each preset file partition.

[0056] In this step, since the target medium is mounted for the first time, it needs to be intelligently partitioned. Combined with the description of step 103 in the above method, the same content will not be repeated here.

[0057] 208. Acquire multiple preset file partitions corresponding to the target medium, and the file type and transmission format corresponding to each preset file partition.

[0058] Among them, the multiple preset file partitions are obtained by intelligently partitioning the target medium according to usage requirements after the target medium is mounted to the burning host for the first time.

[0059] In this step, since the target medium is mounted for the second time, there is no need to re-partition it intelligently. Therefore, the multiple preset file partitions obtained by intelligent partitioning when it is first mounted to the burning host can be directly obtained, as well as the file type and transmission form corresponding to each preset file partition, so as to execute step 209.

[0060] 209. Compare the file hash value and the file version number corresponding to the burned image file in the target medium with the file hash value and the file version number corresponding to the image file to be burned to obtain a comparison result.

[0061] In practical applications, the image file to be burned may be an image file for secondary burning of the target medium, and during this period, the image file to be burned may have version updates or content changes, so in order to avoid repeated burning without version updates or content changes, in this step, the hash values ​​and version numbers of all files can be extracted from the target medium and the image file to be burned, and a comparison list can be generated, listing the hash values ​​and version numbers of each pair of files, so as to facilitate item-by-item comparison. By comparing the hash values ​​and version numbers, the system determines which files already exist on the target medium and have the same content, which files have differences or are missing, and generates a detailed comparison report, listing the comparison results of all files, including consistent files, inconsistent files, and newly added or deleted files, as comparison results. If the comparison results are inconsistent, it means that the image file to be burned actually has version updates or content changes, and step 210a is executed at this time. On the contrary, if the comparison results are consistent, it means that there is no need to repeat the burning of files with the same version and content again, and step 210b is executed at this time.

[0062] 210a. Extract difference file content from the image file to be burned by comparing it with the burned image file, and generate incremental file content from the difference file content.

[0063] In this step, all inconsistent files, i.e., files that need to be updated, are identified according to the comparison report generated in step 209. The contents of these difference files are extracted from the image file to be burned, i.e., only the parts that actually need to be updated are extracted to reduce the amount of transmission and improve efficiency. All difference files are packaged into incremental file contents, usually stored in the form of a compressed package, i.e., an incremental update package, for subsequent transmission and application.

[0064] 210b. Generate an alarm message based on the comparison result, and control the burning host to stop the burning operation of the burning image file.

[0065] In this step, according to the comparison report generated in step 209, an alarm message is generated to inform the user that the file on the target medium is completely consistent with the image file to be burned and does not need to be updated. Specifically, the user may be advised to confirm whether it is indeed not necessary to update or whether there are other tasks that need to be processed. At the same time, the burning host is controlled to immediately stop any further burning operations to avoid unnecessary duplication of work and save time and resources.

[0066] 211. Determine a target file partition corresponding to the incremental file content from among a plurality of preset file partitions according to the file type, and burn the incremental file content into the target file partition in a transmission format corresponding to the target file partition.

[0067] In this step, combined with the description of step 103 in the above method, it is only necessary to replace the file content with the incremental file content, and the same content will not be repeated here.

[0068] Furthermore, when the target medium is mounted on the burning host, the multiple preset file partitions divided by the intelligent partition may also be mounted by other processes except the burning host, which will affect the efficiency and reliability of the system image burning. Therefore, before parsing the image file to be burned in the burning host and extracting the file content contained in the image file to be burned, the method also includes: detecting whether the multiple preset file partitions corresponding to the target medium are mounted by other processes outside the burning host; if so, first unmounting the preset file partitions mounted by other processes and then remounting them to the burning host, and after detecting that they are remounted to the burning host, parsing the image file to be burned in the burning host and extracting the file content contained in the image file to be burned; if not, parsing the image file to be burned in the burning host and extracting the file content contained in the image file to be burned.

[0069] In this step, the mounting status of multiple preset file partitions of the target medium can be checked, and the information of all current mount points, including the mount point path, device identifier, file system type, etc., can be obtained through operating system commands (such as the mount command) or API interfaces. The obtained current mount information is compared with the multiple preset file partitions of the target medium to identify which partitions have been mounted and the location of the mount point. For each preset file partition that has been mounted, further check whether it is being used by other processes. This can be achieved by checking the system's process table (such as the l sof command) to determine whether any process has opened files or directories on the partition.

[0070] According to the above inspection results, if there is no preset file partition being used by other processes, the image file to be burned in the burning host is parsed normally to extract the file content contained in the image file to be burned. If there is a preset file partition being used by other processes, a list of preset file partitions that need to be uninstalled can be generated, that is, a list of preset file partitions being used by other processes. The preset file partitions in the list are uninstalled through operating system commands (such as umount commands) or API interfaces to ensure that each preset file partition mounted by other processes is safely uninstalled, and a prompt message is generated to inform the user of the upcoming operation and provide options for the user to confirm whether to continue. If some preset file partitions cannot be successfully uninstalled because other processes are reading and writing a lot, try to terminate the relevant process or wait for a period of time before trying again. If multiple attempts still fail, a detailed error report is generated and the user is prompted to handle it manually. After all preset file partitions that need to be uninstalled are successfully uninstalled, these partitions are remounted on the burning host. When remounting, make its mount point consistent with the previous setting, ensure that all preset file partitions are correctly mounted to the expected location and are not used by other processes, and record the new mount information.
