Configure operations to ensure the integrity and consistency of data in the cluster.

In order to describe the technical solutions in the embodiments of the present application more clearly and completely, the technical solutions in the embodiments of the present application will be introduced below with reference to the drawings in the embodiments of the present application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

Currently, unified storage is a storage system that can run and manage files and applications on a single device, combining file-based and block-based access. Because it supports different storage protocols to provide data storage for the host system, it is also called multi-protocol storage.

Referring to FIG. 1, FIG. 1 is a schematic structural diagram of a unified storage device disclosed in an embodiment of the present application. Currently, a unified storage device usually consists of multiple controllers to form a redundant structure. The most common method is that two controllers, that is, two nodes, form an IO group, and then multiple IO groups form a final multi-controller cluster.

Under this architecture, node exit and rejoin events may occur frequently due to power failure, business failure or other accidents. Therefore, how to deal with relevant scenarios in a timely and accurate manner, especially complex node event scenarios, becomes very important. important. In view of this, the present application provides a node event processing solution in a unified storage device, which can effectively solve the above problems.

Referring to FIG. 2 , an embodiment of the present application discloses a node event processing apparatus in a unified storage device, which mainly includes:

The node event judgment module 101 is used to determine the content of the node events currently occurring in the cluster and the corresponding nodes in which the node events occur according to the multiple node event messages and the change records of the node online flag bits obtained in sequence, and report to the corresponding service. The processing submodule 102 sends a corresponding operation notification message;

The service processing sub-module 102 is used for executing the corresponding configuration operation according to the operation notification message.

Among them, it should be emphasized that in the embodiment of the present application, the node event judgment module 101 and the service processing sub-module 102 are two independent modules in the cluster, and the node event judgment module 101 is dedicated to judging and acquiring the specific content of the node event, and then can Notify other modules including the service processing sub-module 102 to perform corresponding processing.

It is worth mentioning that, in the embodiment of the present application, the node event judgment module 101 not only receives the node event message from the cluster management center, but also tracks and obtains the change of the online flag bit of the node. Specifically, considering that the node event message in the related art generally only informs the occurrence of a node join event or a node exit event, and does not specifically notify which node has joined or exited the cluster under which specific circumstances, therefore, this In the application, a node online flag bit is specifically set to indicate the current actual online status of each node, and the node event judgment module 101 can simultaneously obtain the change record of the node online flag bit of the node from the cluster management center, so as to combine the node event The message obtains the specific content of the node event, and which node the node event occurs on.

Further, as a specific embodiment, the node online flag bit may be stored in the form of a binary data pair to represent the online status of two nodes in the same IO group. Also, it is possible to use 0 to indicate that the node is not online, and 1 to indicate that the node is online. In this way, the online states of two nodes in the same IO Group may specifically include four states of 00, 01, 10, and 11.

It should be noted that, based on the change record of the node online flag bit, the present application can determine not only the specific type of the node event that occurs, but also the node state in which the node event occurs. It is easy to understand that the configuration operation process required to change from the 11 state to the 10 state is different from that of changing from the 01 state to the 10 state.

Therefore, when a node event occurs, the specific content of the current event can be judged through the node event message and the node online status flag bit, and the corresponding event enumeration variable can be set for each specific event content, so that based on the event enumeration The arguments are passed to the business processing sub-module 102 . The node event judging module 101 transmits the corresponding event enumeration variable to the corresponding business processing sub-module 102 in the form of notification, and at the same time, the node event judging module 101 can control the execution sequence and mutual interaction of other sub-modules according to specific business requirements. dependencies.

After receiving the notification from the node event judging module 101 , the other sub-modules trigger the operation of the state machine in their own modules by monitoring specific event types, and complete the configuration modification suitable for the service processing sub-module 102 .

Among them, the common specific event contents can include the following: the first node joins (00 → 01 or 10) during the initialization process, the second node joins (01 or 10 → 11), the Recovery of one node (00 → 01 or 10), single node failure (11 → 01 or 10), etc.

Specifically, in the actual application process, due to various uncontrollable factors, the occurrence of node events may lead to many more complex scenarios. For example, when a node joins the cluster, and the corresponding configuration operation in the service processing sub-module 102 has not been completely completed (for example, only the second stage of modifying the relevant configuration is processed), the node exits the cluster again due to factors such as power failure, resulting in The case where node events are superimposed. The present application is also applicable to such complex node event scenarios where multiple events are superimposed.

For example, in a normal single-node recovery process (01 → 11), the recovery node exits again, then the node online flag provided by the cluster management center immediately becomes 01 again, and the processing target inside the node event judgment module 101 It is to restore the relevant configuration process inside the service processing sub-module 102 to the state before the node goes online. This can ensure that the changes of cluster nodes can be accurately tracked in real time within the business, so as to avoid affecting specific business processes.

In the face of complex node event combinations, based on the real-time monitoring and timely response of the node event judging module 101, and timely notification to other sub-modules as required, the business processing sub-module 102 can complete the process in a timely and accurate manner during the entire process. corresponding operating procedures.

The node event processing apparatus in the unified storage device disclosed in the embodiment of the present application includes a node event judgment module 101 and a service processing sub-module 102. The node event judgment module 101 is configured to obtain the node event message and the change of the node online flag according to the acquired node event message. record, determine the node event content currently occurring in the cluster and the node where the node event occurs, and send the corresponding operation notification message to the corresponding service processing sub-module 102; the service processing sub-module 102; the service processing sub-module 102 is used for operating The notification message performs the corresponding configuration action.

It can be seen that the node event processing device in the unified storage device disclosed in the embodiment of the present application can accurately obtain the specific content of the node event and locate the specific node by combining the analysis of the node event message and the change record of the node online flag bit, and then It can efficiently handle configuration operations related to node joining or exiting the cluster, effectively ensuring the integrity and consistency of data in the cluster.

As a specific embodiment, the node event processing device in the unified storage device disclosed in the embodiment of the present application is based on the above content, and the node event judgment module 101 records the node state completion flag bit; the node event judgment module 101 also Used for:

After the service processing sub-module 102 performs a corresponding configuration operation according to the operation notification message, a corresponding setting operation is performed on the node status completion flag to indicate that the corresponding node has completed the configuration operation corresponding to its online status.

It is easy to understand that, for the service processing sub-module 102, it should be considered that a node is only regarded as a node that is actually online or offline until the related configuration operations of joining or exiting the cluster are completed. Therefore, in this embodiment, in addition to the node online status flag, a node status completion flag is also set in the node event judging module 101 .

The node event judging module 101 performs the setting operation only after completing the relevant configuration process operations of the node joining or exiting the cluster, so as to ensure that after the node has completed the relevant configuration operations of joining the cluster and can process services normally, it can communicate with others in the cluster. The module communicates between nodes to ensure the validity of the communication data.

As above, in this embodiment, the node online flag is used to indicate the online status of the node provided by the cluster, and the node status completion flag in the node event judgment module 101 is used to indicate the node that matches the processing flow progress of the service processing sub-module 102 at this time. Online status processing, especially suitable for complex superimposed event scenarios. When a superimposed event occurs, the node event judging module 101 can rely on two flags to determine what operation needs to be performed to update the node state completion flag inside the node event judging module 101 to be consistent with the node online flag.

As a specific embodiment, the node event processing apparatus in the unified storage device disclosed in the embodiment of the present application is based on the above content, and the node event message carries the current running state information of the cluster.

Specifically, in this embodiment, the current running state information of the cluster is used to feed back the cluster state, for example, it may specifically include the cluster initialization state, the cluster power-off state, and the like.
