The core of this application is to provide a multi-cluster management method and system, which does not require additional management servers, and the cost of upgrading and transformation is relatively small. When an abnormality occurs, the management terminal can be flexibly switched in other clusters, which can significantly improve the efficiency of managing multi-clusters. Flexibility, saving deployment costs.

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Referring to FIG. 1 below, FIG. 1 is a flow chart of a multi-cluster management method provided by an embodiment of the present application.

It specifically includes the following steps:

S101: Select a cluster from at least two clusters according to a preset selection method, and set a unified management platform on the cluster;

This step aims to select any one of the at least two clusters according to a preset selection method, and perform unified management of other clusters by setting a unified management platform on the management node of the cluster. Wherein, the preset selection method may be selected based on actual conditions and certain principles, for example, the nearest principle, the performance principle, and other special needs, etc., which are not specifically limited here.

This implementation is based on a management environment with multiple clusters. In the prior art, as shown in Figure 2, Figure 2 is a schematic diagram of the traditional multi-cluster management software system architecture. Multiple sets of clusters. The management of multiple clusters adopts the method of setting up a separate management server for unified management, but in this way, because the management authority is too concentrated, and the additional management server will significantly increase the operating cost, once the management server is abnormal or due to Failure to work properly will result in the loss of management of the entire cluster at the same time, which may cause serious economic losses and irreparable data loss.

In response to this technical defect, this embodiment does not add an additional management server, but selects a cluster in a preset manner among multiple clusters, and deploys management applications on the management nodes on it, and through subsequent management operations to achieve Management of other clusters.

S102: Using the unified management platform to send a device discovery message to other clusters except the cluster;

On the basis of S101, this step aims to use the deployed management application to send device discovery messages to clusters other than the deployed management application.

At this point, we can assume that there are three clusters in the entire environment, named 1# cluster, 2# cluster, and 3# cluster respectively in sequence, and at the same time assume that the management application is deployed on the management node of 1# cluster.

Among them, this function can be realized by slightly modifying the existing multi-cluster environment, for example, adding a device discovery module to the management node of the 1# cluster, which usually runs on the management node as a daemon process After the deployment of the entire environment is completed, if you want to realize the unified management of 2# cluster and 3# cluster through this management application, you can send device discovery messages to 2# cluster and 3# cluster through this device discovery module , to wait for whether the feedback command returned by the 2# cluster and the 3# cluster according to the discovery command line can be received.

Usually, it is also necessary to add a corresponding monitoring module on the 2# cluster and the 3# cluster, so as to judge whether to send the corresponding feedback command according to the received device discovery message combined with the instruction. The 2# cluster and the 3# cluster will only return the feedback command when they agree to accept the unified management of the management node on the 1# cluster.

Of course, there are various ways in which the device discovery message and the feedback command are embodied, and the specific composition of the device discovery module. For example, the device discovery message and the feedback command can be a data packet and processed It can also be a special format type of message and feedback message, etc., which are not specifically limited here. It should be based on the specific device model used in the actual situation, the identification format of the management application, and other influences. Factors in comprehensive selection.

At the same time, what form and transmission path does the device use to find the message to reach the 2# cluster and the 3# cluster? There are many specific implementation methods, such as using the IP address or other path information between the two. limited.

S103: Whether the other cluster returns a device response message according to the device discovery message;

On the basis of S102, the purpose of this step is to determine whether the management node of the 1# cluster where the management application is deployed has received the device corresponding message corresponding to the device discovery message, and to determine the 2# cluster and 3# cluster in subsequent steps. #Whether the cluster accepts the unified management of the 1# cluster.

Similar to what is described in S102, even if the 2# cluster and the 3# cluster are under the unified management of the 1# cluster, there are many ways and methods to return a device response message, which will not be detailed here The limit should be comprehensively selected according to the specific device model used in the actual situation, the identification format of the management application, and other influencing factors.

S104: Determine that the other clusters are managed by the unified management platform.

This step is established in S103 when the device response message returned by the 2# cluster and/or the 3# cluster is received according to the corresponding message of the device. At this time, it is determined that the cluster that returns the device response message has accepted the 1# cluster unified management.

Further, after accepting the unified management of the 1# cluster, according to the specific method and path of sending the device discovery message or device response message, the method or path can be added to the management list of the management application and displayed It is also convenient for the administrator to manage it.

Based on the above technical solution, the embodiment of the present application provides a multi-cluster management method. The unified management platform is set in any existing cluster, by sending device discovery messages to other clusters, and receiving the returned device response messages When it is determined that the other cluster agrees to accept the management of the unified management platform. This management method does not need to add additional management servers, and the cost of upgrading and transformation is relatively small. When an exception occurs, the management terminal can be flexibly switched in other clusters, which can significantly improve the flexibility of managing multiple clusters and save deployment costs.

Referring to FIG. 3 below, FIG. 3 is a flow chart of another method for creating multiple namespaces for a solid state disk provided in an embodiment of the present application.

This embodiment is a specific limitation made for the part except S101 in the previous embodiment. Other steps are generally the same as the previous embodiment. For the same parts, please refer to the relevant part of the previous embodiment, which will not be repeated here.

It specifically includes the following steps:

S201: Obtain IP addresses respectively corresponding to the other clusters except the cluster;

In this step, the management application deployed on the management node of the 1# cluster obtains the path information of other clusters, such as the most common path characteristics and identification paths such as IP addresses. Here, the most common IP address is selected as the corresponding Representative information of IP.

S202: Send the device discovery message to the clusters corresponding to each of the IP addresses;

S203: Whether the other cluster returns the device response message from the IP address;

S202 and S203 are designed to use the IP addresses of other clusters obtained in S201 to send UDP-format device discovery messages to 2# clusters and 3# clusters. The device discovery module realizes, correspondingly, by adding the monitoring module on the 2# cluster and the 3# cluster management node to make whether to send the device response message in UDP format according to the issued instruction.

S204: The cluster corresponding to the IP address accepts the management of the unified management platform;

If the management application deployed on the management node of the 1# cluster receives the returned device response message, it will add the cluster corresponding to the IP address to the management application according to the IP address of the returned device response message, indicating that the IP address corresponds to the The cluster accepts the unified management of the management application.

S205: Store the IP address corresponding to the cluster that returns the device response message into the database of the unified management platform, and display it in a list on the management interface of the unified management platform.

This step is substantially the same as that described in step S104, except that the IP address is stored in the database of the unified management application and displayed on the management interface.

Based on the above technical solution, the embodiment of the present application provides a multi-cluster management method, which sets the unified management platform on the management node of any existing cluster according to the preset method, and realizes to Other clusters send device discovery messages and return device response messages, and when receiving device response messages, determine that the other clusters agree to accept the management of the unified management platform.
