Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a method, apparatus, device, and medium for upgrading a distributed storage operating system. Background Technology

[0002] With the rise of big data, cloud computing, and high-performance applications, distributed storage systems have become the de facto backend storage. Early distributed systems, due to their older operating system versions, suffered from stability and security vulnerabilities, leading customers to demand upgrades to domestically developed operating systems for all field nodes. In scenarios involving offline upgrades across operating systems, since distributed storage is mostly located in intranet environments, upgrades typically involve reinstalling the operating system. This method is extremely inefficient, time-consuming, error-prone, and consumes significant manpower. For minor version upgrades, such as upgrading from CentOS 7.4 to 7.8, a yum repository can be created on the local network, and `yum update` can be used to upgrade the operating system. This method is complex to configure and may require manual intervention to resolve package dependencies, resulting in low automation. For major version upgrades, such as upgrading from CentOS 7.4 to CentOS 8.4 or a domestically developed operating system, upgrade tools are typically used. These tools are similar to `yum update`, requiring a yum repository. The entire upgrade process includes three steps: pre-upgrade assessment, upgrade, and post-reboot verification. This method also suffers from complex configuration, long upgrade times, and low automation, making it unacceptable for large-scale online cluster upgrades.

[0003] Therefore, how to reduce the time spent on operating system upgrades and save manpower costs is an urgent problem to be solved in this field. Summary of the Invention

[0020] Optionally, before obtaining the configuration information of the operating system to be upgraded by scanning the operating system to be upgraded, the method further includes:

[0021] Configure a software management repository based on the target operating system.

[0022] Optionally, after migrating the software package in the upgrade data package to the system disk based on the kernel boot file, the process further includes:

[0027] The upgrade module is used to migrate the software package in the upgrade data package to the system disk based on the kernel boot file, so as to upgrade the operating system to be upgraded to the target operating system.

In contrast, this application pre-completes the pre-upgrade and upgrade data package construction before upgrading the storage system, and distributes the upgrade data package to each node to further complete the storage system upgrade. This reduces upgrade time and saves manpower costs. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Since distributed storage is mostly located in intranet environments, upgrades are typically performed by reinstalling the operating system. This method is extremely inefficient, time-consuming, and prone to errors, consuming significant manpower. For minor version upgrades, such as upgrading from CentOS 7.4 to 7.8, a yum repository can be created on the local area network, and the operating system can be upgraded using `yum update`. This method is complex to configure, and manual intervention may be required to resolve package dependencies, resulting in low automation. For major version upgrades, such as upgrading from CentOS 7.4 to CentOS 8.4 or a domestically developed operating system, upgrade tools are generally used. These tools are similar to `yum update`, requiring the creation of a yum repository. The entire upgrade process includes three steps: pre-upgrade assessment, upgrade, and post-reboot verification. This method also suffers from complex configuration, long upgrade times, and low automation, making it unacceptable for large-scale online cluster upgrades.

[0040] Therefore, this application proposes a distributed storage operating system upgrade scheme, which can reduce upgrade time and save manpower costs.

[0041] This application discloses a method for upgrading a distributed storage operating system. (See also...) Figure 1 As shown, the method includes:

[0042] Step S11: Distribute the pre-built upgrade data package to each node; wherein the upgrade data package includes the software packages and kernel boot files that the operating system to be upgraded to the target operating system depends on.

[0043] In this embodiment, the upgrade data package construction process is as follows: The configuration information of the operating system to be upgraded is obtained by scanning the operating system to be upgraded; based on the configuration information, the software packages required to upgrade the operating system to the target operating system are determined. Specifically, the configuration information of the operating system to be upgraded is compared with that of the target operating system, and the software packages required to upgrade the operating system to the target operating system are determined based on the comparison result. After determining the software packages required to upgrade the operating system to the target operating system, the software packages are downloaded from a preset software management repository, and the kernel boot file is generated based on the software packages. Then, the upgrade data package is generated based on the software packages and the kernel boot file. It should be noted that before downloading the software packages from the preset software management repository and generating the kernel boot file based on the software packages, a software management repository needs to be configured based on the target operating system.

[0044] Furthermore, the upgrade data package is distributed to each node; wherein the upgrade data package includes the software packages and kernel boot files that the operating system to be upgraded to the target operating system depends on.

[0045] Step S12: Modify the default boot kernel of each node and restart the node.

[0046] In this embodiment, after the pre-built upgrade data package is distributed to each node, the default boot kernel of each node needs to be modified and the node needs to be restarted. Modifying the default boot kernel ensures that the node uses the latest operating system after restarting.

[0047] Step S13: Based on the kernel boot file, migrate the software package in the upgrade data package to the system disk so as to upgrade the operating system to be upgraded to the target operating system.

[0048] In this embodiment, after restarting the node, the software package in the upgrade data package is migrated to the system disk based on the kernel boot file, so as to upgrade the operating system to be upgraded to the target operating system.

[0049] It should be noted that after migrating the software package in the upgrade data package to the system disk based on the kernel boot file, the process also includes deleting the kernel boot file.

[0050] In summary, traditional distributed storage operating systems perform pre-upgrade assessments and build upgrade data packages for each node before upgrading the storage system. In contrast, this application completes the pre-upgrade and upgrade data package construction before upgrading the storage system and distributes the upgrade data package to each node to further complete the storage system upgrade. This reduces upgrade time and saves manpower costs.

[0051] As can be seen, this application proposes a method for upgrading a distributed storage operating system, comprising: distributing a pre-built upgrade data package to each node; wherein the upgrade data package includes software packages and kernel boot files that the operating system to be upgraded to the target operating system depend on; modifying the default boot kernel of each node and restarting the node; and migrating the software packages in the upgrade data package to the system disk based on the kernel boot file, so as to upgrade the operating system to be upgraded to the target operating system. It is evident that traditional distributed storage operating systems perform pre-upgrade assessment and upgrade data package construction for each node during storage system upgrades, and then perform the upgrade. In contrast, this application pre-completes the pre-upgrade and upgrade data package construction before upgrading the storage system, and distributes the upgrade data package to each node to further complete the storage system upgrade. This reduces upgrade time and saves manpower costs.

[0052] This application discloses a specific method for upgrading a distributed storage operating system. Compared to the previous embodiment, this embodiment further explains and optimizes the technical solution. See also... Figure 2 As shown, it specifically includes:

[0053] Step S21: Distribute the software packages in the pre-built upgrade package to the first directory in each node, distribute the kernel boot file in the upgrade package to the second directory in each node, and decompress it after distribution; wherein, the upgrade package includes the software packages and kernel boot file that the operating system to be upgraded to the target operating system depends on.

[0054] In this embodiment, the software packages in the pre-built upgrade package are distributed to the first directory of each node, and the kernel boot file in the upgrade package is distributed to the second directory of each node. Then, the files in the directory are decompressed after the distribution is completed.

[0055] It should be noted that before distributing the software packages in the pre-built upgrade package to the first directory of each node and distributing the kernel boot file in the upgrade package to the second directory of each node, the upgrade package needs to be constructed. Specifically, this involves scanning the operating system to be upgraded to obtain its configuration information; based on the configuration information, determining the software packages required to upgrade the operating system to the target operating system. Specifically, the configuration information of the operating system to be upgraded is compared with that of the target operating system, and the software packages required to upgrade the operating system to the target operating system are determined based on the comparison results. After determining the software packages required to upgrade the operating system to the target operating system, the software packages are downloaded from a preset software management repository, and the kernel boot file is generated based on the software packages. Then, the upgrade package is generated based on the software packages and the kernel boot file. It should be noted that before downloading the software packages from the preset software management repository and generating the kernel boot file based on the software packages, the software management repository needs to be configured based on the target operating system.

[0056] Step S22: Modify the default boot kernel of each node and restart the node.

[0057] In this embodiment, after the pre-built upgrade data package is distributed to each node, the default boot kernel of each node needs to be modified and the node needs to be restarted. Modifying the default boot kernel ensures that the node uses the latest operating system after restarting.

[0058] Step S23: Based on the kernel boot file in the second directory, migrate the software package in the first directory to the system disk so as to upgrade the operating system to be upgraded to the target operating system.

[0059] It should be noted that after restarting the node, the software packages in the first directory are migrated to the system disk based on the kernel boot file in the second directory, so as to upgrade the operating system to be upgraded to the target operating system. After migrating the software packages in the first directory to the system disk based on the kernel boot file in the second directory, the process further includes deleting the kernel boot file.

[0060] Traditional distributed storage operating systems perform pre-upgrade assessments and build upgrade data packages for each node before upgrading the storage system. In contrast, this application pre-upgrades the storage system and builds the upgrade data packages beforehand, then distributes the upgrade data packages to each node to complete the storage system upgrade. This reduces upgrade time and saves manpower costs.

[0061] As can be seen, this application proposes a method for upgrading a distributed storage operating system, comprising: distributing the software packages in a pre-built upgrade data package to a first directory on each node; distributing the kernel boot file in the upgrade data package to a second directory on each node; and decompressing the packages after distribution; wherein the upgrade data package includes software packages and a kernel boot file that are required to upgrade the operating system to the target operating system; modifying the default boot kernel of each node and restarting the node; and migrating the software packages in the first directory to the system disk based on the kernel boot file in the second directory, so as to upgrade the operating system to the target operating system. It is evident that traditional distributed storage operating systems perform pre-upgrade assessment and upgrade data package construction for each node before upgrading the storage system, while this application pre-completes the pre-upgrade and upgrade data package construction before upgrading the storage system, and distributes the upgrade data package to each node to further complete the storage system upgrade. This reduces upgrade time and saves manpower costs.

[0062] In one specific implementation, this application may include the following:

[0063] The traditional operating system upgrade method is as follows:

[0064] 1. Configure the yum repository (software repository) using ISO at the customer's site; 2. For each node to be upgraded, perform pre-upgrade assessment, upgrade, and reboot. Specifically, the pre-upgrade assessment includes: scanning the system to be upgraded, collecting kernel, software package, and system configuration basic information, comparing and analyzing it with the KOS (target operating system), collecting current system information, and recording the configurations that need to be restored after reboot. If compatibility issues are manually resolved, repeat this step until there are no problems and proceed to the next step. The upgrade specifically includes: based on the collected information and according to the list of software packages currently installed on the system, downloading the necessary upgrade packages from the configured yum repository in advance and triggering the on-site upgrade of all packages to a temporary directory. The reboot node specifically includes: installing the upgrade packages from the temporary directory to the system disk. All of the above steps need to be implemented on-site, which is cumbersome to configure, and compatibility issues require manual intervention to resolve, making the upgrade time-consuming.

[0065] The optimized operating system upgrade method is as follows:

[0066] Since the operating system version and required software packages are consistent across all nodes before the update, this application generates the upgrade tool's source, pre-upgrade assessment, and upgrade within the version build process. The generated upgrade data package is then uploaded to the interface for automated upgrades performed on-site. Specifically, this includes the following steps: 1. Configuring the yum source using an ISO; 2. Pre-upgrade assessment, specifically including: scanning the system to be upgraded, collecting kernel, software package, and system configuration information, comparing and analyzing with KOS, collecting current system information, and recording configurations that need to be restored after reboot; 3. Downloading the required upgrade package inspur-kos.tar.gz from the configured yum source in advance according to the currently installed package list; 4. Creating upgrade-vmlinuz and upgrade-initramfs based on the package (upgrade-vmlinuz, upgrade...). -initramfs is the kernel boot file), and triggers in-situ upgrades of all packages, generating them in / var / lib / inspur; 2. On-site upgrade implementation steps, operated on the interface, include the following: Upload the upgrade package to the interface, which distributes it to all nodes. upgrade-vmlinuz and upgrade-initramfs are distributed to the / boot directory, and inspur.tar.gz is distributed to the / var / lib directory and decompressed; Modify the default boot entry for each node; Reboot; Use the kernel boot file to migrate the operating system under / var / lib / inspur to the system disk; Automatically delete upgrade-vmlinuz and upgrade-initramfs files and update the grub file, using kos as the default bootloader. This completes the operating system upgrade. In other words, this application distributes a pre-built upgrade package to each node; wherein, the upgrade package includes software packages and kernel boot files that the operating system to be upgraded to the target operating system depends on; the default boot kernel of each node is modified, and the node is restarted; based on the kernel boot file, the software packages in the upgrade package are migrated to the system disk, so as to upgrade the operating system to be upgraded to the target operating system. In summary, traditional distributed storage operating systems perform pre-upgrade assessment and upgrade package construction for each node during storage system upgrades, and then perform the upgrade. This application, however, completes the pre-upgrade and upgrade package construction before upgrading the storage system, and distributes the upgrade package to each node to further complete the storage system upgrade. In this way, this application can reduce upgrade time and save manpower costs.

[0067] Accordingly, this application also discloses a distributed storage operating system upgrade device, see [link to relevant documentation]. Figure 3As shown, the device includes:

[0068] The upgrade data packet distribution module 11 is used to distribute the pre-built upgrade data packet to each node; wherein, the upgrade data packet includes the software package and kernel boot file that the operating system to be upgraded to the target operating system depends on.

[0069] After determining the upgrade data package, this application distributes the upgrade data package to each node; wherein, the upgrade data package includes the software package and kernel boot file that the operating system to be upgraded to the target operating system depends on;

[0070] The node restart module 12 is used to modify the default boot kernel of each node and restart the node;

[0071] After distributing the pre-built upgrade package to each node, this application needs to modify the default boot kernel of each node and restart the node. The modification of the default boot kernel ensures that the node uses the latest operating system after restarting.

[0072] Upgrade module 13 is used to migrate the software package in the upgrade data package to the system disk based on the kernel boot file, so as to upgrade the operating system to be upgraded to the target operating system.

[0073] It should be noted that after restarting the node, the software packages in the upgrade data package are migrated to the system disk based on the kernel boot file, so as to upgrade the operating system to be upgraded to the target operating system.

[0074] As can be seen, this application proposes a method for upgrading a distributed storage operating system, comprising: distributing a pre-built upgrade data package to each node; wherein the upgrade data package includes software packages and kernel boot files that the operating system to be upgraded to the target operating system depend on; modifying the default boot kernel of each node and restarting the node; and migrating the software packages in the upgrade data package to the system disk based on the kernel boot file, so as to upgrade the operating system to be upgraded to the target operating system. It is evident that traditional distributed storage operating systems perform pre-upgrade assessment and upgrade data package construction for each node during storage system upgrades, and then perform the upgrade. In contrast, this application pre-completes the pre-upgrade and upgrade data package construction before upgrading the storage system, and distributes the upgrade data package to each node to further complete the storage system upgrade. This reduces upgrade time and saves manpower costs.
