Fig. 1 is a flowchart of a virtual NAS system upgrade method according to an embodiment of the present application. Referring to fig. 1, the virtual NAS system upgrade method includes:
s11: and acquiring an upgrading instruction, and loading an upgrading file in the first NAS node according to the upgrading instruction.
In this embodiment, an upgrade instruction is obtained, and an upgrade file is loaded in the first NAS node according to the upgrade instruction. The NAS system is realized based on a kvm (kernel-based virtual machine), NAS protocols and network communication are realized in the kvm, and service interference caused by upgrading is reduced by optimizing an installation process and a service switching sequence. The NAS virtual host is based on a dual-node unified storage system, and the NAS virtual host form an NAS cluster through internal link communication of the storage system and can independently provide NAS services in a service resource mode. The virtual NAS system owns the boot partition, the system partition, the configuration partition, and the data partition. The startup partition is a first partition, is a read-only partition in a normal mode, and comprises basic system components such as kernel, initramfs (initial ram file system), grub and the like. The system partition is a root file system. The configuration partition stores the customized configuration file and audit log of the user service, and the isolation of the configuration partition and the data partition can completely store the user configuration and the log. The data partition stores the current system installation file backup and the system upgrade (installation) file to be upgraded. The embodiment provides independent NAS system automatic upgrading and rollback functions through multi-partition backup, automatic service switching and automatic configuration reduction.
The upgrading instruction is obtained through timing detection of a storage system or through manual trigger detection, when the fact that the NAS system needs to be upgraded is detected, the upgrading file is firstly downloaded from a cloud server according to the upgrading instruction and is loaded into a data partition of the first NAS node, then verification information corresponding to the upgrading file is downloaded from the cloud server, and the upgrading file loaded into the first NAS node is verified through the verification information. A configuration node (upgrade node) downloads an upgrade file and a check code file of a cloud to a data partition in a local NAS system, where the configuration node is the first NAS node in this embodiment.
S12: and transferring the service resources in the first NAS node to a second NAS node by controlling the first NAS node to be in a standby state.
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 traffic resources and network resources. And independently upgrading the NAS system by applying configuration and data partitioning and controlling the transfer of service resources. Before that, the NAS system of the first NAS node already has the upgrade installation file, and after receiving the upgrade command, the NAS system performs verification, and if the upgrade file passes the verification, the NAS system triggers generation of an identifier file corresponding to the upgrade file and including information of the upgrade file by calling the upgrade command. The identification file is an upgrade flag file written with the version information of the upgrade file. Namely, if the verification is successful, the upgrading flag file is created and the information of the upgrading packet is written.
On this basis, the NAS cluster makes the first NAS node enter a standby mode, the network service on this node is stopped, so as to block the client service, then the rest protocol service resources are stopped and loaded and started in the second NAS node, the network resource is transferred in the same manner after the start is completed, and at this time, the client service is recovered to be normal. The influence on the client is reduced by carrying out resource transfer on the node standby in advance.
S13: and upgrading the virtual NAS system in the first NAS node by using the upgrading file, and re-transferring the service resources transferred to the second NAS node to the first NAS node after upgrading operation.
In this embodiment, the upgrade file is used to perform an upgrade operation on the virtual NAS system in the first NAS node, and the service resource transferred to the second NAS node is transferred to the first NAS node after the upgrade operation again. Specifically, the first NAS node is restarted, whether the restarted first NAS node includes an identifier file is judged through an initramfs file system, and when the identifier file, that is, an upgrade flag file, is detected, an upgrade process is triggered by self-test. And adding a detection and installation program into initramfs, and automatically checking and upgrading the initramfs when the initramfs are started every time.
Reading the identification file to determine the corresponding upgrade file, decompressing the upgrade file, updating the corresponding data in the first NAS node boot partition and the system partition by using the decompressed upgrade file, deleting the identification file, restarting the updated first NAS node, and finally performing initialization operation and re-authentication operation on the restarted first NAS node. In the process, after the first NAS node is restarted, initramfs firstly judges whether the data partition has the upgrade flag file, if so, the corresponding upgrade packet is decompressed according to the information in the file, the corresponding start and the content in the system partition are replaced, and the flag file is deleted and restarted after the completion. And after the first NAS node is started, generating a system name according to the storage node information and completing basic initialization. Re-authentication joins the NAS cluster.
And after the upgrade file is installed, re-transferring the service resources transferred to the second NAS node to the first NAS node after the upgrade operation. The second NAS node blocks client traffic by deactivating network resources that were otherwise running on the first NAS node. And the rest protocol resources which are originally operated on the first NAS node are transferred to the first NAS node again, the relevant service is subjected to self-checking, and the network is recovered after the self-checking is successful. At this time, the resource of the node (the first NAS node) takes over, then, the configuration is re-issued for the client configuration and the current version, and the configuration file in the configuration partition of the first NAS node after the upgrade operation is re-configured to obtain the new configuration file adapting to the virtual NAS system after the upgrade operation, that is, the current protocol version is adapted according to the configuration in the current configuration partition. And finally, self-checking the currently running protocol process, transferring network resources after no error occurs, completing the upgrading of the first NAS node after the transfer is completed, and recovering the service of the client. And after the first NAS node finishes upgrading, transmitting the upgrading file to the second NAS node to be upgraded through the same steps in the embodiment, so that the upgrading of the whole cluster is realized.
In order to ensure certain fault tolerance, when an error occurs in the upgrading operation, the old upgrading file backed up in the first NAS node data partition is used for rollback upgrading. And when the step fails, actively triggering rollback, and carrying out an installation process by using an old version upgrade package in the data partition. And when the upgrade generates an error, the rollback mechanism restores the backup upgrade package in the data partition. After the upgrading operation of the first NAS node and the second NAS node is completed, deleting other upgrading files in the data partition except the upgrading file corresponding to the virtual NAS system after the upgrading operation, so that only the upgrading file corresponding to the virtual NAS system after the upgrading operation is stored in the data partition. And after the two nodes are upgraded, deleting the upgrade package of the old version in the data partition, and only keeping the upgrade package consistent with the current version.
As can be seen, in the embodiment of the present application, an upgrade instruction is obtained first, and an upgrade file is loaded in a first NAS node according to the upgrade instruction; then, transferring the service resources in the first NAS node to a second NAS node in a mode of controlling the first NAS node to be in a standby state; and finally, upgrading the virtual NAS system in the first NAS node by using the upgrading file, and re-transferring the service resources transferred to the second NAS node to the first NAS node after upgrading operation. The embodiment of the application is based on a double-node unified storage system, service resource transfer is performed by fully utilizing two nodes, an upgrade file is loaded to an upgrade node when an upgrade instruction is obtained, the upgrade node is set to be in a standby state so as to block a client service, then the service resource is transferred to another node and upgrade operation is performed on the upgrade node by utilizing the upgrade file, the service resource is transferred to the upgrade node after upgrade is completed, only temporary blocking is performed on a client in the whole upgrade process, universality is strong, the influence on the node service is small, and automatic independent upgrade of a virtual NAS system in a cluster node is realized.
