FIG. 1 shows a flow diagram of an update method for a hyper-converged cluster, according to one embodiment of the invention.
As shown in fig. 1, the method includes:
and 102, establishing a temporary container for any node in the super-fusion cluster according to the configuration information of the node.
The super-convergence cluster is a working cluster consisting of a large number of software systems, wherein each software system can be regarded as a node, and the super-convergence cluster is regarded as a working network consisting of a large number of nodes.
Because the updating required by the super-fusion cluster is not necessarily all the nodes, the updating is only carried out on the nodes needing to be updated, and the whole work of the super-fusion cluster is not suspended, so that the influence of the updating on the work performance of the super-fusion cluster is reduced. Meanwhile, because the node needing to be updated is also a member of the super-fusion cluster, in order to avoid the condition that the whole performance of the super-fusion cluster is influenced because the node cannot work in the updating process, a temporary node can be established for the node, and the node is replaced by the temporary node to work in the super-fusion cluster.
For any node needing to be updated in the super-fusion cluster, configuration information such as a self configuration file, a system configuration file, environment variables and the like can be acquired. And establishing a temporary container with the same configuration information as the node based on the configuration file, the system configuration file and the environment variable, and migrating data such as storage content, execution tasks and the like of the node to the temporary container. In this way, the temporary container has both the configuration information of the node, performs the same operation as the node, and has the same data as the node, so that the data to be processed in the node can be processed based on the configuration information of the node.
And 104, taking the node off line, and setting the temporary container as a temporary node.
And 106, replacing the nodes with the temporary containers to work in the super-fusion cluster.
After the temporary container is established, the temporary container can be used for effectively replacing the work of the node in the super-converged cluster.
And step 108, performing service updating on the offline nodes according to the updating information.
And 110, replacing the temporary container with the updated node to work in the super-fusion cluster.
And then, acquiring the update information of the node, and updating the service of the offline node according to the update information. And after the updating is finished, replacing the temporary container with the updated node, and returning to the super-fusion cluster for working.
And updating all the nodes needing to be updated by adopting the method until all the nodes needing to be updated are updated.
According to the technical scheme, the super-fusion cluster can be updated gradually without stopping the work of any node in the super-fusion cluster, the influence of the updating process on the working performance of the super-fusion cluster is reduced, the labor cost and the time cost required by updating are reduced, and the user experience is also improved.
FIG. 2 shows a flow diagram of an update method for a hyper-converged cluster, according to another embodiment of the invention.
As shown in fig. 2, the method includes:
The super-convergence cluster is a working cluster consisting of a large number of software systems, wherein each software system can be regarded as a node, and the super-convergence cluster is regarded as a working network consisting of a large number of nodes.
Because the updating required by the super-fusion cluster is not necessarily all the nodes, the updating is only carried out on the nodes needing to be updated, and the whole work of the super-fusion cluster is not suspended, so that the influence of the updating on the work performance of the super-fusion cluster is reduced. Meanwhile, because the node needing to be updated is also a member of the super-fusion cluster, in order to avoid the condition that the whole performance of the super-fusion cluster is influenced because the node cannot work in the updating process, a temporary node can be established for the node, and the node is replaced by the temporary node to work in the super-fusion cluster.
For any node needing to be updated in the super-fusion cluster, configuration information such as a self configuration file, a system configuration file, environment variables and the like can be acquired. And establishing a temporary container with the same configuration information as the node based on the configuration file of the temporary container, the system configuration file and the environment variable.
And migrating the first data of the storage content, the execution task and the like of the node to a temporary container. In this way, the temporary container has the configuration information of the node, performs the same operation as the node, and has the same data as the node.
Each node in the super-converged cluster accesses other nodes through the node allocation information of the port access management list of the super-converged cluster. Specifically, for any node, the port access management list has the port information of the node that it can access listed therein. Therefore, after the temporary container replacement node is established, the temporary access port information of the temporary container needs to be added to the port access management list of the super-converged cluster. Specifically, the other node that originally accessed the port information of the node may be set in the port access management list, and the temporary access port information of the temporary container may be accessed, or the temporary access port information of the temporary container may be added to the accessible port information of the other node that originally accessed the port information of the node.
The temporary container has the configuration information of the node, performs the same work as the node, has the same data as the node, and has the original data interaction path between the node and other nodes.
And step 208, taking the node off line, and setting the temporary container as a temporary node.
And 210, replacing the nodes with the temporary containers to work in the super-fusion cluster.
And 212, performing service updating on the offline node according to the updating information.
After the temporary container is established, the temporary container can be used for effectively replacing the work of the node in the super-converged cluster. And updating all the nodes needing to be updated by adopting the method until all the nodes needing to be updated are updated.
And 214, migrating the second data in the temporary container to the updated node.
After the update of the node is completed, because the temporary container replaces the node to work, the original first data is changed into second data after working. If the updated node still returns to the work of the super-fusion cluster with the first data, data errors can be caused, and the working performance of the node itself and the upstream and downstream nodes is affected. Therefore, the second data of the temporary container at this time needs to be migrated to the updated node, so that the updated node has valid data synchronized with the super-converged cluster at this time.
Because the updated node is replaced, the temporary access port information of the temporary container is useless, the temporary access port information can be deleted in the port access management list, and the access port information of the updated node is placed or recovered at the deletion position of the temporary access port information.
The designated data is key data for efficient work of the super-fusion cluster, if the designated data of the nodes are consistent, the data migration is successfully completed in the updating process of the nodes, the designated data of the nodes are synchronous, and the super-fusion cluster is in a normal working state.
If the specified data of the plurality of nodes are inconsistent, it is indicated that an error occurs in data migration in the updating process of the nodes, the specified data of each node is asynchronous, and the specified data as a key is asynchronous, so that an error occurs in the overall work of the hyper-fusion cluster.
And under the condition that the designated data of the nodes are inconsistent, in order to avoid the influence of subsequent data processing errors caused by the inconsistency of the designated data, selecting a main node, and setting the designated data of the main node as unified designated data of the nodes. Therefore, the designated data of each node can be automatically updated to be consistent, and the condition that errors occur in the work of the super-fusion cluster due to the fact that the designated data are inconsistent is avoided.
In one possible design, the master node is a highest weighted node of the plurality of nodes. The higher the node weight is, the higher the importance of the node in the super-fusion cluster is, the designated data of the node with the highest weight is taken as the designated data of a plurality of nodes, and the work of the super-fusion cluster can be ensured to be carried out on the basis of the data of the node with the highest importance.
In another possible design, the master node is a node of the plurality of nodes with a data source hierarchy at a lowest level. The lower the data source hierarchy of a node, the closer the node is, the earlier it processes data than other nodes. The node of the plurality of nodes at the lowest level of the data source hierarchy is the node that was the earliest to contact or generate the designated data, which may have changed during its communication to other nodes. Therefore, the plurality of nodes can be given the specified data of the node at the lowest level of the data source hierarchy as a standard.
