Description

Technical Field

[0001] This application relates to the field of resource management technology, and in particular to a cluster resource management method, apparatus and computer equipment. Background Technology

[0002] Pacemaker is the most widely used open-source cluster resource manager in Linux environments. It leverages the messaging and cluster member management capabilities provided by the cluster infrastructure to achieve fault detection and resource recovery at the node and resource levels, thereby maximizing the high availability of cluster services. When many resources exist, if timely monitoring is required, necessitating calls to the monitoring agent within seconds, excessive resource calls to the corresponding agent can put excessive pressure on the CIB process. Since Pacemaker relies on the CIB process to handle all resources, too many resources can cause the CIB process to remain in a pending state, leading to delays in processing new resources and potentially causing system anomalies.

[0003] Therefore, there is an urgent need to propose a cluster resource management method, device, and computer equipment that can reduce CIB processes, decrease resource drift time, and avoid system anomalies caused by untimely processing by the resource manager under multiple resources.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] The cluster resource management method provided in this application can be applied to, for example... Figure 1In the application environment shown, terminal 102 communicates with server 104 via a network. Terminal 102 inputs the resource types that need to be classified to server 104, and server 104 performs cluster resource management based on the instructions issued by terminal 102. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, and tablets, and server 104 can be a standalone server or a server cluster consisting of multiple servers.

[0036] In one embodiment, such as Figure 2 As shown, a cluster resource management method is provided, which is applied to the Pacemaker mechanism. Figure 1 Taking the server in the example, the following steps are included:

[0037] The resources in the resource database are classified according to resource type, and resources of the same type are integrated into the clone resource library;

[0038] Obtain the node to which the resources in the cloned resource repository belong, and mount the cloned resource repository to the node, wherein there is at least one node;

[0039] Each node manages the resources belonging to it based on the cloned resource library.

[0040] Specifically, the node to which the resource in the cloned repository belongs is obtained, and the cloned repository is mounted to that node, where there is at least one node. Taking a file system as an example, suppose there are three nodes: node 1, node 2, and node 3. Node 1 and node 3 both contain a file system, while node 2 does not. Therefore, to integrate the file system into the cloned repository, the cloned repository is mounted to nodes 1 and 3, but not to node 2.

[0041] In the above-mentioned cluster resource management method, resources of the same type are integrated into a clone resource library. All resources of the same type under the cluster are managed through a single clone resource library. When managing the resources of nodes, the management of resources of the same type can be achieved through the mechanism of Pacemaker itself without relying on Pacemaker's own CIB process. This effectively reduces the requirements of Pacemaker itself on the CIB process, and can complete multi-resource processing even in a low-cost environment.

[0042] Specifically, in a clustered storage system, there are various resource types, including file systems and shared resources. Assuming a node has 200 file systems, and resource monitoring and management are required within the cluster, especially under time-sensitive conditions (e.g., monitoring all file system resources within 5 seconds), then using existing technology, these 200 file systems would complete their monitoring within that timeframe, resulting in 200 agent calls. Such numerous agent calls within a short period put excessive pressure on the CIB process. If new resources are added at this time, the system will experience problems due to the CIB process's delayed processing. Furthermore, when the node fails, the 200 file systems need to be unloaded from that node and then mounted to other normally functioning nodes to complete the resource switchover. If this switchover takes too long, it hinders effective fault handling for the node and negatively impacts system stability.

[0043] Based on the cluster resource management method described in this application, resources are classified according to resource type and integrated into a clone resource library. Taking file systems as an example, all file systems under the cluster storage system are obtained and integrated into the clone resource library; then, based on the node to which the resources in the clone resource library belong, the clone resource library is mounted to that node; finally, resource management is performed on the resources corresponding to itself in the clone resource library on each node mounted with the clone resource library. This application does not create an independent resource for each file, but creates a clone resource library for resources of the same type under the cluster. This not only allows management of the file systems on the corresponding nodes on each node, but also eliminates the need for only one agent call within 5 seconds to manage resources of 200 file systems in the cluster, reducing the pressure on the CIB process and ensuring that the CIB can handle other resources. Furthermore, when one node fails, integrating resources of the same type into the clone resource library reduces resource drift time. Based on the node sequence list, resource switching can be quickly achieved, reducing resource switching time and improving fault resolution efficiency.

[0044] In one embodiment, the method further includes: obtaining a node that is mounted with the cloned resource library, wherein the node is at least one; generating relational mapping data based on the node and the resources belonging to the node; and generating a node sequence list based on the relational mapping data.

[0045] Specifically, assuming there are three nodes mounted with the cloned resource library: node 1, node 2, and node 3; node 1 contains file system 1, node 2 contains file system 3, and node 3 contains file system 4, then node 1 and file system 1 generate relational mapping data 1, node 2 and file system 3 generate relational mapping data 2, and node 3 and file system 4 generate relational mapping data 3; the relational mapping data is obtained to generate a node sequence table, that is, the node sequence contains relational mapping data 1, relational mapping data 2, and relational mapping data 3. More specifically, the node sequence table contains node 1, node 2, node 3, file system 1, file system 3, and file system 4.

[0046] In one embodiment, such as Figure 3 As shown, each node manages its resources based on the clone resource library, including: obtaining the node's running status and determining whether the node's running status is normal; if the node's running status is normal, each node manages its resources based on the clone resource library; if the node's running status is abnormal, a candidate node is obtained based on the node sequence list to manage the node's resources.

[0047] In one embodiment, such as Figure 3 As shown, before obtaining candidate nodes to manage the resources of the node based on the node sequence list, the method further includes: determining whether there are preset candidate nodes; if there are preset candidate nodes, then managing the resources of the node based on the candidate nodes; if there are no preset candidate nodes, then performing a load stress test on the node with the cloned resource library mounted; and based on the load stress test results, obtaining candidate nodes to manage the resources of the node.

[0048] In one embodiment, such as Figure 3 As shown, if there are preset alternative nodes, resource management is performed on the resources of the node based on the alternative nodes, including: obtaining the running status of the preset alternative nodes; if the running status of the preset alternative nodes is normal, resource management is performed on the resources of the node based on the alternative nodes; if the running status of the preset alternative nodes is abnormal, a stress test is performed on the node with the cloned resource library mounted, and resource management is performed on the nodes based on the stress test results.

[0049] In one embodiment, such as Figure 3As shown, based on the load stress test results, candidate nodes are selected for resource management of the nodes, including: performing a load stress test on each node mounted with the cloned resource library and obtaining the stress test results; sorting the load stress test results in ascending order of load stress test values ​​to generate a sequence list; selecting candidate nodes according to the candidate node selection rules based on the sequence list; and performing resource management of the nodes based on the candidate nodes.

[0050] In one embodiment, the candidate node acquisition rule includes: sequentially acquiring nodes corresponding to the stress test values ​​based on the ordered list, defining the nodes corresponding to the stress test values ​​as candidate nodes; acquiring the running status of the candidate nodes based on the candidate nodes; acquiring candidate nodes with normal running status as candidate nodes, and performing resource management on the resources of the nodes based on the candidate nodes.

[0051] In one embodiment, resource management of the node's resources includes at least one of resource mounting, resource monitoring, and resource unloading.

[0052] It should be understood that, although Figure 2-3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders.

These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.
