Description

Technical Field

[0001] This application belongs to the field of computer technology, and particularly relates to a method, apparatus, device, and storage medium for adjusting partition space. Background Art

[0002] Currently, the Linux system is upgraded to implement different functions. The upgrade generally involves updating the version of the operating system to add new functions, fix vulnerabilities, or improve performance. The system upgrade can involve updates in multiple aspects such as the kernel, drivers, application programs, and library files. Generally, the Linux system is partitioned to store the images in the upgrade package, thereby completing the upgrade of the Linux system.

[0003] In the traditional solution, when making partition division before upgrading, a large part of redundant storage space needs to be reserved for each partition to ensure that the partition can meet the changes in partition size brought about by future version changes. This will inevitably lead to waste of storage space; moreover, it cannot be guaranteed that the reserved partition size will definitely be larger than the required size for the upgrade. If this situation occurs, the upgrade function will no longer be able to be used normally. Summary of the Invention

[0018] By reading the detailed description of the preferred embodiments below, various other advantages and benefits will become clear to those of ordinary skill in the art. The drawings are only for the purpose of showing the preferred embodiments and are not considered to be a limitation of the present application. Moreover, throughout the drawings, the same reference numerals are used to represent the same components.

[0025] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be fully conveyed to those skilled in the art.

[0026] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should have the ordinary meanings understood by those skilled in the art to which the present application belongs.

[0027] The partition space adjustment method of the present application can be executed by a computing device. The computing device can be a server, such as a single server, multiple servers, a server cluster, a cloud computing platform, etc. Optionally, the computing device can also be a terminal device, such as a mobile phone, a tablet computer, a game console, a portable computer, a desktop computer, an advertising machine, an all-in-one computer, etc. The present application does not limit the device type and the number of devices of the computing device.

[0028] Continuing with the above background technology, when making partition division before the traditional solution is upgraded, a large part of redundant storage space needs to be reserved for each partition to ensure that the partition can meet the change in partition size brought about by future version changes. This will inevitably lead to waste of storage space; moreover, it cannot be guaranteed that the reserved partition size will definitely be larger than the size required for the upgrade. If this situation occurs, the upgrade function will no longer be able to be used normally.

[0029] To solve the technical problem of waste of storage space caused by fixed partition division in the Linux system upgrade solution, in the related art, the partition is expanded when the partition size is insufficient, but there may still be waste of storage space after the expansion. For example, if the current partition size is 1G and the actual upgrade package size is 500M, then the partition will not be expanded, resulting in a waste of 500M of storage space. Even after the upgrade is completed, this part of the storage resource cannot be utilized by the system.

[0030] To solve the above technical problems, the present application proposes a method, apparatus, device, and storage medium for partition space adjustment. The method includes: obtaining upgrade images corresponding to each partition to be upgraded in an upgrade package; determining the storage space required for each upgrade image; and re-partitioning all partitions based on the storage space required for each upgrade image. In the embodiments of the present application, each partition is dynamically adjusted according to the actual partition size required for each upgrade during each upgrade, reducing redundant space and making more efficient use of the storage space.

[0031] For the execution entity, in each embodiment of the present application, a computing device is taken as an example for illustration.

[0032] The following describes a method for partition space adjustment proposed according to an embodiment of the present application with reference to the accompanying drawings.

[0033] See Figure 1 , the method specifically includes the following steps:

[0034] S101. Obtain upgrade images corresponding to each partition to be upgraded in the upgrade package.

[0035] Among them, the upgrade package may include upgrade images corresponding to all partitions in the Linux system, or include upgrade images corresponding to the partitions to be upgraded. The upgrade package generally includes a set of files for system upgrade, including all files and scripts required for system update, such as kernels, drivers, library files, and configuration files, etc. The upgrade package can be incremental (only update the changed parts) or complete (include all components of the system).

[0036] An image is a form of file storage and a type of redundancy. A complete copy of the data on one disk exists on another disk, which is called an image.

[0037] The upgrade package can be transferred to the computing device through Over-the-Air Technology (OTA) or other means (such as a USB flash drive). Generally, the upgrade package is compressed. After obtaining the compressed package, it will be stored locally first, and after receiving the upgrade instruction, the upgrade package will be decompressed first to obtain upgrade images corresponding to each partition to be upgraded.

[0038] S102. Determine the storage space required for each upgrade image.

[0039] In some embodiments, the storage space required for each upgrade image can be viewed through the command line. For example, the du command can be used to obtain the size of each image. The du command can specifically be du -h -max-depth=1 <partition_image_file>.

[0040] In some other embodiments, when making an upgrade package, the storage space required for each upgrade image is packaged and placed in the upgrade package, and the storage space required for each upgrade image is directly read from the upgrade package before each upgrade.

[0041] S103. Redivide all partitions based on the storage space required for each upgrade image.

[0042] Among them, during the Linux system upgrade process, the AB dual-partition upgrade method can be adopted, that is, the system is divided into two parts, A and B, and different system versions are run in the two parts respectively or used as a backup. During the upgrade, one part is used for updating, and the other part continues to provide services, so as to achieve seamless switching and rollback during system update and ensure system stability.

[0043] Before the upgrade, parts A and B can be respectively divided into multiple partitions, and all partitions are multiple partitions divided for the storage space of each part.

[0044] The storage space of multiple partitions can be determined based on the storage space required for the corresponding upgrade image. For example, if the storage space required for the upgrade image is 500M, then the storage space of the corresponding partition can be 500M, 550M, etc., which can avoid the waste of storage resources caused by the traditional fixed partition method.

[0045] This application proposes a partition space adjustment method, device, equipment and storage medium. The method includes: obtaining the upgrade image corresponding to each partition to be upgraded in the upgrade package; determining the storage space required for each upgrade image; and redividing all partitions based on the storage space required for each upgrade image. In the embodiments of this application, each partition is dynamically adjusted according to the actual partition size required for the current upgrade during each upgrade, reducing redundant space and making more efficient use of the storage space.

[0046] In some embodiments, the upgrade package includes a first upgrade package corresponding to a full-package upgrade. The first upgrade includes upgrade images corresponding to all partitions. Redividing all partitions based on the storage space required for each upgrade image includes: determining the first target storage space corresponding to each partition, where the first target storage space is greater than or equal to the storage space required for the corresponding upgrade image and less than the first preset storage space; and redividing all partitions based on each first target storage space.

[0047] As can be seen from the above, the upgrade package can include upgrade images corresponding to all partitions in the Linux system, that is, the upgrade package can be the first upgrade package corresponding to a full-package upgrade, that is, the upgrade package corresponding to each upgrade includes upgrade images corresponding to all partitions, that is, all partitions are considered to be partitions to be upgraded.

[0048] After receiving the first upgrade package, the upgrade images corresponding to all partitions in the first upgrade package can be obtained, and the storage space of the corresponding partitions can be determined based on the upgrade images. Among them, the first preset storage space can be the same as the storage space required for the corresponding upgrade image, or just greater than the storage space required for the corresponding upgrade image. For example, it can be 1.1 times, 1.2 times, etc. of the storage space required for the corresponding upgrade image.

[0049] After determining the first target storage spaces corresponding to all partitions respectively, the storage space of part A or part B is divided to obtain the divided target partitions. When the storage space of part A or part B is less than the sum of the storage spaces corresponding to all partitions, the free space of the Linux system is obtained, and part of the space is divided from the free space so that the storage space of part A or part B is greater than or equal to the sum of the storage spaces corresponding to all partitions, so as to complete the division of all partitions.

[0050] In some embodiments, the upgrade package includes a second upgrade package for differential upgrade. The second upgrade includes the upgrade images corresponding to the partitions to be upgraded. Based on the storage spaces required for each upgrade image respectively, all partitions are repartitioned, including: determining the second target storage spaces corresponding to all partitions to be upgraded respectively, where the second target storage space is greater than or equal to the storage space required for the corresponding upgrade image and less than the second preset storage space; obtaining the first original images corresponding to the other partitions respectively; determining the storage spaces required for the first original images corresponding to the other partitions respectively; determining the third target storage spaces corresponding to the other partitions respectively based on the storage spaces required for each first original image, where the third target storage space is greater than or equal to the storage space required for the corresponding first original image and less than the third preset storage space; repartitioning all partitions based on each second target storage space and each third target storage space.

[0051] As can be seen from the above, the upgrade package can include the upgrade images corresponding to the partitions to be upgraded respectively, that is, the upgrade package can be the second upgrade package for differential upgrade, and the second upgrade package does not include the upgrade images corresponding to all partitions, but only includes the upgrade images corresponding to the partitions to be upgraded.

[0052] After receiving the second upgrade package, the upgrade images corresponding to all partitions in the second upgrade package can be obtained, and the storage space of the corresponding partitions can be determined based on the upgrade images. Among them, the second preset storage space can be the same as the storage space required for the corresponding upgrade image, or just greater than the storage space required for the corresponding upgrade image. For example, it can be 1.1 times, 1.2 times, etc. of the storage space required for the corresponding upgrade image.

[0053] In addition, the first original image corresponding to each of the other partitions will be obtained; the storage space required for the first original image corresponding to each of the other partitions will be determined; the other partitions are the other partitions among all partitions except the partition to be upgraded, and the third target storage space corresponding to each of the other partitions will be determined based on the storage space required for each first original image, where the third preset storage space can be the same as the storage space required for the corresponding original image, or just greater than the storage space required for the corresponding original image, such as 1.1 times, 1.2 times, etc. of the storage space required for the corresponding original image.

[0054] After determining the target storage space corresponding to each partition, the storage space of part A or part B is divided to obtain the partitioned target partitions. When the storage space of part A or part B is less than the sum of the storage spaces corresponding to all partitions, the free space of the Linux system is obtained, and a part of the space is divided from the free space so that the storage space of part A or part B is greater than or equal to the sum of the storage spaces corresponding to all partitions, so as to complete the partitioning of all partitions.

[0055] In some embodiments, based on the storage space required for each upgrade image respectively, all partitions are repartitioned, including: unmounting the second original image corresponding to each partition respectively; deleting all partitions; partitioning multiple target partitions corresponding to the storage space required for each upgrade image respectively.

[0056] It can be understood that to repartition the partitions, the original partitions need to be cleared. Correspondingly, the second original image corresponding to each partition can be unmounted first, and all partitions can be deleted, that is, the storage space of all partitions is divided into a total storage space, and then the total storage space is further divided based on the storage space required for each upgrade image respectively to obtain multiple target partitions.

[0057] In some embodiments, the above operations can be performed through the command line. For example, the command line umount / dev / can be used. <device>Unmount the target partition to facilitate subsequent operations. You can use the parted tool and execute the command in the command line: parted / dev / <device>rm<part_num>Delete the partition you want to delete. You can use the parted tool and execute the command in the command line: parted / dev / <device>mkpart primary ext4 <start_size> <part_size> Recreate a new partition.

[0058] In some embodiments, the method further includes: formatting the re-partitioned target partition; inputting the upgrade images into their respective corresponding target partitions.

[0059] After partitioning the target partition, the re-partitioned target partition will be formatted to input the respective corresponding upgrade images into the target partition, and further input the upgrade images into their respective corresponding target partitions so that each target partition can implement the functions corresponding to the upgrade image.

[0060] Among them, the target partition can be reformatted through the mkfs tool to match the current system, using the command line command: mkfs.ext4 / dev / <device>Complete partition formatting.

[0061] In some embodiments, based on each second target storage space and each third target storage space, all partitions are repartitioned, including: when the sum of the storage spaces of each second target storage space and each third target storage space is greater than the original storage space of all partitions, obtaining free space; repartitioning based on the free space and the original storage space to obtain the target partitions obtained by repartitioning.

[0062] It can be understood that when the sum of the storage spaces of the target spaces obtained by repartitioning may be greater than the original storage space of all partitions, that is, when the sum of the storage spaces of each second target storage space and each third target storage space is greater than the original storage space of all partitions, free space is obtained, where the free space may be the storage space of other parts of the Linux system.

[0063] In some embodiments, the storage space of the Linux system is as Figure 2 shown. The Linux system includes partitions A and B. In addition, it also includes a variable data partition (var partition), a root file system partition (root partition), a swap partition (swap partition), etc. The images can be Kernel image, Rootfs image, opt image, etc. Each image corresponds to a target partition of partitions A and B. The free space can be one of the variable data partition, the root file system partition, and the swap partition. Since the main function of the variable data partition is to store variable data generated during system operation, such as log files, cache files, temporary files, mail queues, etc., therefore, when the storage spaces of partitions A and B are insufficient, the storage space can be preferentially obtained from the variable data partition as free space.

[0064] Furthermore, repartition the free space and the original storage space of partition A or B to obtain the target partitions obtained by repartitioning.

[0065] In some embodiments, the method further includes: obtaining the second original image corresponding to each partition; determining the storage space required for the second original image corresponding to each partition; determining the fourth target storage space corresponding to each partition based on the storage space required for each second original image, where the third target storage space is greater than or equal to the storage space required for the corresponding second original image and less than the fourth preset storage space; partitioning the partition of each second original image according to each fourth target storage space.

[0066] It can be understood that before the Linux system is upgraded, the partitions will be divided for the first time, that is, the second original image corresponding to each partition is obtained; the storage space required for the second original image corresponding to each partition is determined, and further, based on the storage space required for each second original image, the fourth target storage space corresponding to each partition is determined. Among them, the fourth preset storage space can be the same as the storage space required for the corresponding original image, or just larger than the storage space required for the corresponding original image. For example, it can be 1.1 times, 1.2 times, etc. of the storage space required for the corresponding original image. Each partition of the second original image is divided according to each fourth target storage space.

[0067] Since all partitions will be re-divided each time there is an upgrade, therefore, a large part of redundant storage space is reserved for each partition when dividing the partitions for the first time to ensure that the partition can meet the changes in the partition size brought about by future version changes. Therefore, redundant space can be reduced, making the storage space more fully utilized.

[0068] The embodiment of the present application also provides a partition space adjustment device, which is used to execute the partition space adjustment method provided in any of the above embodiments. As Figure 3 shown, the device includes: an acquisition module 301, a determination module 302, and a division module 303.

[0071] The division module 303 is used to re-divide all partitions based on the storage space required for each of the upgrade images.

[0072] The present application proposes a partition space adjustment method, device, device, and storage medium.

[0075] Based on each of the first target storage spaces, re-partition all the partitions.

[0076] In some embodiments, the upgrade package includes a second upgrade package corresponding to differential upgrade, and the second upgrade includes an upgrade image corresponding to the partition to be upgraded. The partitioning module 303 is further specifically configured to:
