Description

Technical Field

[0001] This invention relates to the field of computer technology, and specifically to a virtual cluster startup control method, system, device, and storage medium. Background Technology

[0002] In the control of virtual cluster startup, a virtual cluster refers to an independent cluster created on top of a physical cluster through virtual containers or virtualization, which can independently provide services, such as a NAS AP cluster system. A key aspect of cluster control is preventing split-brain scenarios. Common practice is to use arbitration to determine which node should start the service, preventing multiple endpoints from starting simultaneously and causing data inconsistency. Furthermore, a separate arbitration device is required. Summary of the Invention

[0003] In view of this, the purpose of this invention is to propose an improved virtual cluster startup control method, system, storage medium and device, which does not require a separate arbitration device. When the virtual machine already contains cluster machine service configuration information, the startup state will depend on the physical cluster state to determine the virtual machine startup state, thereby determining whether to take over resources and start services.

[0004] To achieve the above objectives, in one respect, the present invention provides a virtual cluster startup control method, wherein the method includes the following steps:

[0005] Get the number of virtual clusters contained in the entire physical cluster. The virtual clusters are isolated from each other by network. Within the same virtual cluster, only one virtual machine is started on the physical machine.

[0006] The heartbeat links within the physical cluster are virtualized into virtual cluster heartbeat links, and the heartbeat link status of the physical cluster is consistent with the virtual heartbeat link status.

[0007] Virtual nodes on physical machines communicate with all physical machines in the cluster where the physical machine resides, as well as the virtual nodes on the corresponding physical machines.

[0008] As a further aspect of the present invention, if the physical machine is not in the cluster, the network will be isolated, and the virtual nodes on the physical machine will not be able to communicate with the other physical nodes and the virtual nodes of the other physical nodes.

[0009] As a further aspect of the present invention, virtual machines and physical machines communicate with each other via a heartbeat link, wherein the message communication is used to obtain basic operating information.

[0010] As a further aspect of the present invention, the virtual cluster startup control method further includes:

[0011] After the virtual machine starts, it first checks if a cluster configuration exists. If no cluster configuration exists, it waits to be added to the cluster or to rebuild the cluster. If a cluster configuration exists, it first checks if the physical node is online in the cluster. If it is not online, it waits and does not start the cluster. If the current physical node is online, it starts the cluster.

[0012] As a further aspect of the present invention, when other physical nodes are online at the same time, if only the current node virtual machine is started, the cluster is started; if other node virtual machines are started, it is first determined whether the heartbeat between the virtual machines is connected.

[0013] If connectivity exists, start the cluster; otherwise, check if the heartbeat connection with the physical node is established.

[0014] If all nodes are connected, it means the link is normal. Other nodes are either in the startup or stuck phase. Start the cluster. Otherwise, restart and check the status until the status is correct before starting the cluster.

[0015] As a further aspect of the present invention, if only the current node is started after the cluster is started and the heartbeat of other nodes is not connected, the heartbeat of the corresponding physical node is connected to query the virtual machine status. If it can be found, it means that there is a problem inside the virtual machine. The virtual machine is restarted and all resources are started. If it cannot be found, the resources are taken over directly.

[0016] As a further aspect of the present invention, if the heartbeat of the corresponding physical node cannot be connected, it is determined whether the current physical node is a configured node. If so, all resources are taken over; if it is not a configured node, the current virtual machine is restarted and the startup process is re-entered.

[0017] As a further embodiment of the present invention, if there are nodes with heartbeat communication, they are added to the cluster, and resources are started on the corresponding nodes according to the preset node priority.

[0018] As a further aspect of the present invention, the virtual cluster startup control method further includes:

[0019] At startup, it first determines whether the single-node startup condition is met. After starting the cluster, it then determines the status of each virtual machine node to decide whether to take over resources to provide services.

[0020] Another aspect of the present invention provides a virtual cluster startup control system, comprising:

[0021] The virtual cluster configuration module is used to obtain the number of virtual clusters contained in the entire physical cluster. The virtual clusters are isolated from each other by network. Within the same virtual cluster, only one virtual machine is started on the physical machine.

[0022] The virtualization module is used to virtualize the heartbeat links within the physical cluster into the heartbeat links of the virtual cluster. The heartbeat link status of the physical cluster is consistent with the virtual heartbeat link status.

[0023] The node communication module is used for communication between virtual nodes on physical machines and all physical machines in the cluster where the physical machine is located, as well as the virtual nodes on the corresponding physical machines.

[0024] In another aspect, the present invention provides a computer device including a memory and a processor, wherein the memory stores a computer program that, when executed by the processor, performs any of the virtual cluster startup control methods according to the present invention.

[0025] In another aspect, the present invention provides a computer-readable storage medium storing computer program instructions that, when executed, implement any of the virtual cluster startup control methods according to the present invention.

[0026] The present invention has at least the following beneficial technical effects:

[0027] This invention proposes a virtual cluster startup control method, system, storage medium, and device. It determines whether to start the cluster and take over resources by the status of each node when the virtual node starts, without the need for a separate arbitration device. When the virtual machine already contains cluster machine service configuration information, it will rely on the status of the physical cluster to determine the status of the virtual machine at startup, thereby determining whether to take over resources and start services.

[0028] In addition, the virtual cluster startup control method first determines whether it meets the single-node startup criteria. After the cluster starts, it assesses the status of each virtual machine node to decide whether to take over resources to provide services. By judging the current physical node, the heartbeat connectivity status with each physical node, and the heartbeat status between virtual nodes, it ultimately determines the node that will start the service resources, providing a solution for cluster startup without arbitration.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0038] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two different entities or different parameters with the same name. Therefore, "first" and "second" are merely for convenience of expression and should not be construed as limiting the embodiments of the present invention. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, such as other steps or units inherent in a process, method, system, product, or device that includes a series of steps or units.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0041] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] The common practice for preventing split-brain in a cluster is to use arbitration to determine which node the service should start, preventing multiple devices from starting simultaneously and causing data inconsistency. In addition, a separate arbitration device is required.

[0043] Therefore, this invention proposes an improved virtual cluster startup control method, system, storage medium, and device. It eliminates the need for a separate arbitration device. When the virtual machine already contains cluster machine service configuration information, the startup state depends on the physical cluster state to determine whether to take over resources and start the service.

[0044] See Figure 1 As shown, an embodiment of the present invention provides a virtual cluster startup control method, wherein the method includes the following steps S10-S30;

[0045] Step S10: Obtain the number of virtual clusters contained in the entire physical cluster. The virtual clusters are isolated from each other by network. In the same virtual cluster, only one virtual machine is started on the physical machine.

[0046] Step S20: Virtualize the heartbeat link within the physical cluster into a virtual cluster heartbeat link, and the heartbeat link status of the physical cluster is consistent with the virtual heartbeat link status.

[0047] Step S30: The virtual nodes on the physical machine communicate with all physical machines in the cluster where the physical machine is located, as well as the virtual nodes on the corresponding physical machines.

[0048] In some embodiments, if a physical machine is not in the cluster, the network is isolated, and the virtual nodes on that physical machine cannot communicate with the other physical nodes and the virtual nodes of the other physical nodes.

[0049] In this embodiment of the invention, only one virtual machine in the same virtual cluster is started on the physical machine, but the entire physical cluster can contain multiple virtual clusters, and the networks between the virtual clusters are isolated. In this embodiment, the heartbeat link within the physical cluster is used to virtualize the heartbeat link of the virtual cluster, ensuring that the heartbeat link status of the physical cluster is consistent with the virtual heartbeat link status. Therefore, the virtual nodes on the physical machine can communicate with all physical machines in the cluster where the physical machine is located, as well as the virtual machine nodes on the corresponding physical machines. If the physical machine is not in the cluster, the network will be isolated, and its virtual nodes will not be able to communicate with other physical nodes or their virtual nodes.

[0050] In some embodiments of the present invention, virtual machines and physical machines communicate with each other via a heartbeat link, wherein the message communication is used to obtain basic operating information.

[0051] In this embodiment, the basic operational information obtained can be CPU pressure, network traffic, virtual machines existing on the physical machine, etc.

[0052] In some embodiments, after the virtual machine starts, it first checks whether a cluster configuration exists. If not, it waits to be added to the cluster or to rebuild the cluster. If a cluster configuration exists, it first determines whether the physical nodes are online in the cluster. If not, it waits without starting the cluster.

[0053] If only the current physical node is online, then start the cluster. If other physical nodes are online simultaneously, and only the current node's virtual machine is running, then start the cluster; if other node virtual machines are running, first check if the heartbeat connection with the other virtual machines is working. If it is, then start the cluster; otherwise, check if the heartbeat connection with the physical nodes is working. If both are working, the link is normal, and the other node virtual machines are either starting up or stuck, then start the cluster. Otherwise, restart and check the status; only start the cluster if the status is satisfactory.

[0054] In some embodiments, after starting the cluster, if only the current node starts and cannot communicate with the heartbeats of other nodes, the heartbeat of the corresponding physical node is used to query the virtual machine status. If the status can be found, it indicates that there is a problem inside the virtual machine. The virtual machine is restarted and all resources are started. If the status cannot be found, the resources are taken over directly.

[0055] If the heartbeat of the corresponding physical node fails to connect, determine whether the current physical node is a configured node. If it is, take over all resources; otherwise, restart the current virtual machine and re-enter the startup process. If a node with a working heartbeat exists, add it to the cluster, and start resources on the corresponding node according to the preset node priority.

[0056] In some embodiments of the present invention, the virtual cluster startup control method further includes:

[0057] At startup, it first determines whether the single-node startup condition is met. After starting the cluster, it then determines the status of each virtual machine node to decide whether to take over resources to provide services.

[0058] In this embodiment of the invention, the control method for starting the virtual cluster is mainly to determine the node for starting the business resources by judging the current physical node, the heartbeat connectivity status with each physical node, and the heartbeat status between virtual nodes.

[0059] If, at startup, only the current virtual machine node exists and the corresponding physical node is in a cluster state, then the cluster is started.

[0060] If there are other physical nodes in the cluster, the decision to start the cluster is based on the heartbeat connectivity status between the current node and the other physical nodes.

[0061] After the cluster starts, if it cannot communicate with the virtual nodes of other nodes via heartbeat, it will determine whether to start the resources based on the heartbeat status with the corresponding physical node and whether it is a configured node. If the existing virtual nodes are communicating via heartbeat, they will form a cluster, and the resources will be started on the corresponding nodes according to the node start order configured in the resource settings.

[0062] It should be noted that the above figures are merely illustrative of the processes included in the method according to exemplary embodiments of the present invention, and are not intended to be limiting. It is readily understood that the processes shown in the above figures do not indicate or limit the temporal order of these processes. Furthermore, it is readily understood that these processes may, for example, be executed synchronously or asynchronously in multiple modules.

[0064] The virtual cluster configuration module 100 is used to obtain the number of virtual clusters contained in the entire physical cluster. The virtual clusters are isolated from each other by network. In the same virtual cluster, only one virtual machine is started on the physical machine.

[0065] The virtualization module 200 is used to virtualize the heartbeat link within the physical cluster into a virtual cluster heartbeat link, and the state of the physical cluster heartbeat link is consistent with the state of the virtual heartbeat link.

[0066] The node communication module 300 is used for communication between virtual nodes on physical machines and all physical machines in the cluster where the physical machine is located, as well as the virtual nodes on the corresponding physical machines.

[0067] It should be understood that although the above description follows a certain order, these steps are not necessarily executed in that order. Unless otherwise expressly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, some steps in this embodiment may include multiple steps or multiple stages, which are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be performed alternately or in turn with other steps or at least a portion of the steps or stages in other steps.
