Description

Technical Field

[0001] The present invention relates to the technical field of storage systems, and in particular to a virtual NAS system upgrade method, device, equipment and storage medium. Background Art

[0002] A NAS (Network Attached Storage) system is a system that connects storage devices to an existing network to provide data and file services. A NAS server generally consists of several parts, including storage hardware, an operating system, and a file system on it. NAS directly connects to disk storage arrays via the network, and the magnetic arrays have features such as high capacity, high performance, and high reliability. NAS connects storage devices to the Internet directly through a standard network topology without the need for a server, and does not rely on a general operating system. Instead, it uses a simplified operating system designed for users and specifically for data storage. It has built-in protocols required for network connection, making the management and setup of the entire system relatively simple. Currently, when upgrading the NAS system in a NAS cluster, it can only be upgraded as a whole, and the system of a single node cannot be upgraded separately, making the system upgrade efficiency of the NAS cluster low.

[0003] Therefore, how to provide an efficient virtual NAS system upgrade solution is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a virtual NAS system upgrade method, apparatus, device and storage medium, which can automatically and individually upgrade the virtual NAS systems in cluster nodes.

[0008] Transferring service resources in the first NAS node to the second NAS node by controlling the first NAS node to be in a standby state;

[0009] The virtual NAS system in the first NAS node is upgraded using the upgrade file, and the service resources transferred to the second NAS node are transferred back to the first NAS node after the upgrade operation.

[0010] Optionally, loading the upgrade file in the first NAS node according to the upgrade instruction includes:

[0012] Optionally, after loading the upgrade file in the first NAS node according to the upgrade instruction, the method further includes:

[0013] Verification information corresponding to the upgrade file is downloaded from the cloud server, so as to verify the upgrade file loaded into the first NAS node using the verification information.

[0014] Optionally, before transferring the service resources in the first NAS node to the second NAS node by controlling the first NAS node to be in a standby state, the method further includes:

[0015] If the upgrade file passes the verification, triggering the generation of an identification file corresponding to the upgrade file and containing information about the upgrade file by calling an upgrade command;

[0016] Accordingly, the upgrading operation on the virtual NAS system in the first NAS node using the upgrade file includes:

[0017] Restarting the first NAS node and determining whether the restarted first NAS node contains an identification file through the initramfs file system;

[0018] If yes, the identification file is read to determine the corresponding upgrade file, and the upgrade file is decompressed to perform an upgrade operation on the virtual NAS system in the first NAS node using the decompressed upgrade file.

[0019] Optionally, the upgrading the virtual NAS system in the first NAS node by using the decompressed upgrade file includes:

[0020] Using the decompressed upgrade file, update the corresponding data in the boot partition and system partition of the first NAS node;

[0021] Deleting the identification file and restarting the first NAS node after the update process;

[0022] Perform initialization and re-authentication operations on the restarted first NAS node.

[0023] Optionally, after transferring the service resources transferred to the second NAS node back to the first NAS node after the upgrade operation, the method further includes:

[0024] The configuration file in the configuration partition of the first NAS node after the upgrade operation is reconfigured to obtain a new configuration file adapted to the virtual NAS system after the upgrade operation.

[0025] Optionally, the virtual NAS system upgrade method further includes:

[0026] If an error occurs during the upgrade process, the old upgrade file backed up in the data partition of the first NAS node is used to perform a rollback upgrade.

[0027] After the upgrade operation is completed, other upgrade files except the upgrade file corresponding to the virtual NAS system after the upgrade operation are deleted from the data partition, so that only the upgrade file corresponding to the virtual NAS system after the upgrade operation is stored in the data partition.

[0028] A second aspect of the present application provides a virtual NAS system upgrade device, comprising:

It can be seen that this application is based on a dual-node unified storage system, making full use of two nodes for service resource transfer, loading the upgrade file to the upgrade node when the upgrade instruction is obtained, blocking the client business by setting the upgrade node to standby state, and then transferring the service resources to another node and upgrading the upgrade node using the upgrade file. After the upgrade is completed, the service resources are transferred to the upgrade node. During the entire upgrade process, there is only a short blockage for the client, which is highly versatile and has little impact on the node business, thereby realizing automatic and separate upgrades of the virtual NAS system in the cluster node.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Currently, when upgrading the NAS system in a NAS cluster, it can only be upgraded as a whole, and it is impossible to upgrade the system of a single node separately, which makes the system upgrade efficiency of the NAS cluster low. In response to the above technical defects, the present application provides a virtual NAS system upgrade solution, which is based on a dual-node unified storage system and makes full use of the two nodes to transfer service resources. When the upgrade instruction is obtained, the upgrade file is loaded into the upgrade node, and the client service is blocked by setting the upgrade node to standby state. Then, the service resources are transferred to another node and the upgrade node is upgraded using the upgrade file. After the upgrade is completed, the service resources are transferred to the upgrade node. During the entire upgrade process, there is only a short blockage for the client, which is highly versatile and has little impact on the node service, thereby realizing the automatic and separate upgrade of the virtual NAS system in the cluster node.

[0041] Figure 1 This is a flowchart of a virtual NAS system upgrade method provided by an embodiment of the present application. Figure 1 As shown, the virtual NAS system upgrade method includes:

[0042] S11: Obtain an upgrade instruction, and load an upgrade file in the first NAS node according to the upgrade instruction.

[0043] In this embodiment, an upgrade instruction is obtained and, based on the upgrade instruction, the upgrade file is loaded into the first NAS node. The NAS system is implemented based on KVM (kernel-based virtual machine), which implements the NAS protocol and network communication. By optimizing the installation process and service switching sequence, service disruption caused by the upgrade is reduced. The NAS virtual host is based on a two-node unified storage system. The two communicate via the storage system's internal links to form a NAS cluster and independently provide NAS services through service resources. The virtual NAS system has a boot partition, a system partition, a configuration partition, and a data partition. The boot partition is the first partition and is read-only in normal mode. It contains basic system components such as the kernel, initramfs (initial RAM file system), and grub. The system partition is the root file system. The configuration partition stores customized configuration files and audit logs for user services. The isolation of the configuration partition from the data partition ensures the complete preservation of user configuration and logs. The data partition stores backups of the current system installation files and the system upgrade (installation) files to be upgraded. This embodiment provides independent NAS system automatic upgrade and rollback capabilities through multi-partition backup, automatic service switching, and automatic configuration restoration.

[0044] The upgrade instruction is obtained through periodic detection by the storage system or through manual triggering. When it is detected that the NAS system needs to be upgraded, the upgrade file is first downloaded from the cloud server according to the upgrade instruction and loaded into the data partition of the first NAS node. Then, verification information corresponding to the upgrade file is downloaded from the cloud server, and the upgrade file loaded into the first NAS node is verified using the verification information. The configuration node (upgrade node) downloads the upgrade file and verification code file from the cloud to the data partition of the local NAS system. In this embodiment, the configuration node is the first NAS node.

[0045] S12: Transferring service resources in the first NAS node to the second NAS node by controlling the first NAS node to be in a standby state.

[0046] In this embodiment, the service resources in the first NAS node are transferred to the second NAS node by controlling the first NAS node to be in a standby state. The service resources include business resources and network resources. By using configuration and data partitioning, the upgrade of the NAS system is completed separately through the transfer control of business resources. Prior to this, the NAS system of the first NAS node already has an upgrade installation file. When the upgrade command is received, a verification is performed. If the upgrade file verification passes, the generation of an identification file corresponding to the upgrade file and containing the information of the upgrade file is triggered by calling the upgrade command. The identification file is an upgrade flag file with the version information of the upgrade file written in it. That is, if the verification is successful, an upgrade flag file is created and the information of the upgrade package is written in it.

[0047] Based on this, the NAS cluster puts the first NAS node into standby mode, stopping the network services on this node to block client services. It then stops the remaining protocol service resources and loads and restarts them on the second NAS node. After the restart is complete, network resources are transferred in the same way, and client services resume normal operation. By preemptively placing the node in standby mode and transferring resources, the impact on customers is minimized.

[0048] S13: Using the upgrade file, perform an upgrade operation on the virtual NAS system in the first NAS node, and transfer the service resources transferred to the second NAS node back to the first NAS node after the upgrade operation.

[0049] In this embodiment, the virtual NAS system in the first NAS node is upgraded using the upgrade file, and the service resources that were transferred to the second NAS node are re-transferred to the upgraded first NAS node. Specifically, the first NAS node is restarted and the initramfs file system is used to determine whether the restarted first NAS node contains an identification file. Upon detecting the identification file, or upgrade flag file, a self-test triggers the upgrade process. A detection and installation program is added to the initramfs file, automatically checking and upgrading the system at each startup.

[0050] First, read the identification file to determine the corresponding upgrade file, and decompress the upgrade file. Then, use the decompressed upgrade file to update the corresponding data in the boot partition and system partition of the first NAS node. At the same time, delete the identification file and restart the first NAS node after the update. Finally, perform initialization and re-authentication operations on the restarted first NAS node. In the above process, after the first NAS node is restarted, initramfs first determines whether the data partition has an upgrade flag file. If so, it decompresses the corresponding upgrade package according to the information in the file, and replaces the content in the corresponding boot and system partitions. After completion, delete the flag file and restart. After the first NAS node is started, it generates a system name based on the storage node information and completes basic initialization. Re-authenticate and join the NAS cluster.

[0051] After the upgrade file is installed, the service resources transferred to the second NAS node are transferred back to the upgraded first NAS node. The second NAS node stops the network resources originally running on the first NAS node to block client services. The remaining protocol resources originally running on the first NAS node are transferred back to the first NAS node and self-verify the related services. After the self-verification is successful, the network is restored. At this point, the local node (the first NAS node) takes over its own resources. Then, the configuration is re-issued based on the customer configuration and the current version. The configuration file in the configuration partition of the upgraded first NAS node is reconfigured to obtain a new configuration file adapted for the upgraded virtual NAS system. In other words, the current protocol version is adapted according to the configuration in the current configuration partition. In this embodiment, user configuration is automatically restored without manual import, completing a fully automated upgrade. Finally, the currently running protocol process is self-checked. If it is correct, the network resources are transferred. After the transfer is complete, the upgrade of the first NAS node is completed and client services are restored. After the upgrade of the first NAS node is complete, the upgrade file is transferred to the second NAS node and upgraded through the same steps as in this embodiment, thereby completing the upgrade of the entire cluster.

[0052] In order to ensure a certain degree of fault tolerance, when an error occurs in the upgrade operation, the old upgrade file backed up in the data partition of the first NAS node is used to roll back the upgrade. When a failure occurs in the above steps, the rollback is actively triggered, and the old version of the upgrade package in the data partition is used to carry out the installation process. When an error occurs during the upgrade, the rollback mechanism will restore the backup upgrade package in the data partition. After the upgrade operation of the first NAS node and the second NAS node is completed, the other upgrade files in the data partition except the upgrade file corresponding to the virtual NAS system after the upgrade operation are deleted, so that only the upgrade file corresponding to the virtual NAS system after the upgrade operation is saved in the data partition. After the upgrade of both nodes is completed, the old version of the upgrade package in the data partition is deleted, and only the upgrade package consistent with the current version is retained.

[0053] It can be seen that the embodiment of the present application first obtains the upgrade instruction, and loads the upgrade file in the first NAS node according to the upgrade instruction; then the service resources in the first NAS node are transferred to the second NAS node by controlling the first NAS node to be in the standby state; finally, the virtual NAS system in the first NAS node is upgraded using the upgrade file, and the service resources transferred to the second NAS node are transferred back to the first NAS node after the upgrade operation. The embodiment of the present application is based on a dual-node unified storage system, which makes full use of the two nodes to transfer service resources. When the upgrade instruction is obtained, the upgrade file is loaded into the upgrade node, and the client service is blocked by setting the upgrade node to the standby state. Then, the service resources are transferred to another node and the upgrade node is upgraded using the upgrade file. After the upgrade is completed, the service resources are transferred to the upgrade node. During the entire upgrade process, there is only a short blockage for the client, which is highly versatile and has little impact on the node service, thereby realizing the automatic and separate upgrade of the virtual NAS system in the cluster node.
