[0041] The computing node working status detection method provided in this application can be applied to Figure 1 In the application environment shown, the physical host system 102 communicates with the storage system 104 through a network or an input / output port. The physical host system 102 and the storage system 104 can be implemented using independent servers or a server cluster consisting of multiple servers.

[0042] In one embodiment, Figure 2 As shown, a method for detecting the working status of a computing node is provided. Figure 1 The physical host system 102 in the example is used for description, including the following steps 201 to 204.

[0043] Step 201, in response to receiving a node connection mapping list sent by a storage system, control each node to establish a connection with a logical storage unit of a storage area network in the corresponding storage system according to the node connection mapping list.

[0044] The nodes include management nodes and computing nodes. The node connection mapping list is used to represent the mapping relationship between each node and the logical storage unit of the storage area network in the corresponding storage system.

[0045] Specifically, when the physical host system 102 recognizes that it has received the node connection mapping list sent by the storage system, it controls each node to establish a connection with a logical storage unit of a storage area network in the corresponding storage system according to the node connection mapping list.

[0046] In one embodiment, if Figure 3 As shown, in response to receiving the node connection mapping list sent by the storage system, before controlling each node to establish a connection with a logical storage unit of a storage area network in the corresponding storage system according to the node connection mapping list, step 301 is also included.

[0047] Step 301: Send a storage unit creation instruction to the storage system, so that the storage system creates each logical storage unit according to the storage unit creation instruction, generates and sends a node connection mapping list to the physical host system.

[0048] Specifically, the physical host system 102 issues a storage unit creation instruction to the storage system, so that the storage system creates each logical storage unit according to the storage unit creation instruction, generates and sends a node connection mapping list to the physical host system, thereby improving the efficiency and convenience of obtaining the node connection mapping list.

[0049] In a specific example, in the input and output interface mode, a logical storage unit (LUN) is provided for management nodes and computing nodes through a storage area network (SAN). All nodes in the server cluster can access the same LUN provided by the SAN, and the minimum LUN capacity is 1M i B. The LUN is divided into 2048 blocks according to 512B, and each node in the server cluster corresponds to a block on the LUN, so the cluster management supports a minimum of 2048 nodes. A unique identification document (ID) and a unique node name are assigned to each node in the cluster. The node ID ranges from 0 to 2047. The node with ID value i can only access the i-th block on the LUN. The above is only a specific example. In actual applications, it is flexibly set according to user needs and is not limited here.

[0050] In this embodiment, a storage unit creation instruction is issued to the storage system so that the storage system creates each logical storage unit according to the storage unit creation instruction, generates and sends a node connection mapping list to the physical host system, thereby improving the efficiency and convenience of obtaining the node connection mapping list.

[0051] Step 202: In response to performing configuration operations on each node, generating node configuration information, and configuring the corresponding node according to the node configuration information.

[0052] Specifically, when the physical host system 102 identifies that a configuration operation is to be performed on each node, it generates node configuration information and configures the corresponding node according to the node configuration information.

[0053] In one embodiment, if Figure 4 As shown, in response to performing configuration operations on each node, node configuration information is generated, and the corresponding node is configured according to the node configuration information, including step 401 and step 402.

[0054] Step 401, in response to a configuration operation on a management node, generates the first absolute path information of the logical storage unit corresponding to the management node, computing node information of each computing node, the reading interval time of the logical storage unit of the management node, the writing interval time of the logical storage unit of the management node, and the working mode.

[0055] Step 402: configure the corresponding management node according to the node configuration information corresponding to the management node.

[0056] The computing node information includes the Internet Protocol address (IP), node identification number and node name of the corresponding computing node; the working mode is the input and output interface working mode; the node configuration information corresponding to the management node includes the first absolute path information, each computing node information, logical storage unit read interval time, logical storage unit write interval time and working mode. In addition, the working mode can also be set to network mode.

[0057] Specifically, when the physical host system 102 recognizes that a configuration operation is being performed on a management node, it generates the first absolute path information of the logical storage unit corresponding to the management node, the computing node information of each computing node, the reading interval of the logical storage unit of the management node, the writing interval of the logical storage unit of the management node, and the working mode; then, it configures the corresponding management node according to the node configuration information corresponding to the management node, thereby improving the efficiency and convenience of the management node configuration.

[0058] In this embodiment, in response to a configuration operation on a management node, the first absolute path information of the logical storage unit corresponding to the management node, the computing node information of each computing node, the reading interval of the logical storage unit of the management node, the writing interval of the logical storage unit of the management node, and the working mode are generated; then, the corresponding management node is configured according to the node configuration information corresponding to the management node, thereby improving the efficiency and convenience of the management node configuration.

[0059] In one embodiment, if Figure 4 As shown, in response to performing configuration operations on each node, node configuration information is generated, and the corresponding node is configured according to the node configuration information, and also includes steps 403 and 404.

[0060] Step 403 , in response to performing configuration operations on each computing node, generating second absolute path information of a logical storage unit corresponding to the corresponding computing node, a node identification number of the corresponding computing node, and a node name of the corresponding computing node.

[0061] Step 404: configure the corresponding computing nodes according to the node configuration information corresponding to each computing node.

[0062] The configuration information corresponding to the computing node includes the corresponding second absolute path information, the computing node information of the corresponding computing node, and the node name of the corresponding computing node. Specifically, when the physical host system 102 recognizes that a configuration operation is to be performed on each computing node, it generates the second absolute path information of the logical storage unit corresponding to the corresponding computing node, the node identification number of the corresponding computing node, and the node name of the corresponding computing node; then, the corresponding computing node is configured according to the node configuration information corresponding to each computing node, thereby improving the efficiency and convenience of computing node configuration.

[0063] In this embodiment, in response to the configuration operation on each computing node, the second absolute path information of the logical storage unit corresponding to the corresponding computing node, the node identity identification number of the corresponding computing node and the node name of the corresponding computing node are generated; then, the corresponding computing node is configured according to the node configuration information corresponding to each computing node, thereby improving the efficiency and convenience of the computing node configuration.

[0064] Step 203, in response to the management node operating mode being the input / output interface operating mode, start each node, control each computing node to periodically update the corresponding logical storage unit, and control the management node to read the current storage content of each logical storage unit.

[0065] Specifically, when the physical host system 102 recognizes that the working mode of the management node is the input / output interface working mode, it starts each node, controls each computing node to periodically update the corresponding logical storage unit, and controls the management node to read the current storage content of each logical storage unit.

[0066] In one embodiment, if Figure 5 As shown, in response to the management node's working mode being the input / output interface working mode, each node is started, each computing node is controlled to periodically update the corresponding logical storage unit, and the management node is controlled to read the current storage content of each logical storage unit, including steps 501 to 502.

[0067] Step 501, in response to the management node operating mode being the input / output interface operating mode, each node is started, each computing node is controlled to periodically update the corresponding logical storage unit according to the logical storage unit write interval, and the standard update write time of each computing node is recorded.

[0068] Step 502: Control the management node to read the current storage content of each corresponding logical storage unit according to the logical storage unit reading interval.

[0069] The currently stored content includes a node identification number of the corresponding computing node, a node name of the corresponding computing node, an updated content of the corresponding computing node, and a content update timestamp of the corresponding computing node.

[0070] Specifically, when the physical host system 102 recognizes that the working mode of the management node is the input / output interface working mode, it starts the operation on each node, controls each computing node to periodically update the corresponding logical storage unit according to the write interval of the logical storage unit, and records the standard update write time of each computing node; then, it controls the management node to read the current storage content of each corresponding logical storage unit according to the read interval of the logical storage unit, thereby improving the efficiency and accuracy of obtaining the current storage content of each corresponding logical storage unit.

[0071] In this embodiment, in response to the working mode of the management node being the input / output interface working mode, each node is started, and each computing node is controlled to periodically update the corresponding logical storage unit according to the write interval of the logical storage unit, and the standard update write time of each computing node is recorded; then, the management node is controlled to read the current storage content of each corresponding logical storage unit according to the read interval of the logical storage unit, thereby improving the efficiency and accuracy of obtaining the current storage content of each corresponding logical storage unit.

[0072] Step 204: determine the working status of the corresponding computing node according to the current storage content of each logical storage unit.

[0073] The working state includes working normally or working abnormally. Specifically, the physical host system 102 determines the working state of the corresponding computing node according to the current storage content of each logical storage unit, thereby avoiding misjudgment of the detection result due to a network connection failure between the management node and the computing node, reducing the complexity of the system, improving the availability, maintainability and flexibility of the system cluster management, reducing costs, and improving the detection accuracy and real-time performance of the computing node working state.

[0074] Based on this, the above-mentioned computing node working status detection method, in response to receiving the node connection mapping list sent by the storage system, controls each node to establish a connection with the logical storage unit of the storage area network in the corresponding storage system according to the node connection mapping list; the node includes a management node and each computing node; then, in response to the configuration operation of each node, generates the configuration information of the node, and configures the corresponding node according to the node configuration information; then, in response to the working mode of the management node being the input and output interface working mode, starts each node, controls each computing node to update the corresponding logical storage unit periodically, and controls the management node to read the current storage content of each logical storage unit; finally, judges the working status of the corresponding computing node according to the current storage content of each logical storage unit, thereby avoiding misjudgment of the detection result due to the network connection failure between the management node and the computing node, reducing the complexity of the system, improving the availability, maintainability and flexibility of cluster management of the system, and reducing the cost, while improving the detection accuracy and real-time performance of the working status of the computing node.

[0075] In one embodiment, if Figure 6 As shown, judging the working status of the corresponding computing node according to the current storage content of each logical storage unit includes steps 601 to 603.

[0076] Step 601, determining whether the content update timestamp of the corresponding computing node in each currently stored content is the same as the standard update write time of the corresponding computing node;

[0077] Step 602: If they are the same, determine that the working state of the corresponding computing node is normal;

[0078] Step 603: If they are not the same, it is determined that the working state of the corresponding computing node is abnormal.

[0079] Specifically, the physical host system 102 determines whether the content update timestamp of the corresponding computing node in each currently stored content is the same as the standard update write time of the corresponding computing node; then, if they are the same, it determines that the working status of the corresponding computing node is normal; then, if they are not the same, it determines that the working status of the corresponding computing node is abnormal, thereby improving the efficiency and accuracy of judging the working status of the computing node.

[0080] In this embodiment, it is determined whether the content update timestamp of the corresponding computing node in each currently stored content is the same as the standard update write time of the corresponding computing node; then, if they are the same, it is determined that the working status of the corresponding computing node is normal; then, if they are not the same, it is determined that the working status of the corresponding computing node is abnormal, which improves the efficiency and accuracy of judging the working status of the computing node.

[0081] In one embodiment, the method further comprises:

[0082] If the first target node name is the same as the second target node name and the first target node identity identification number is the same as the second target node identity identification number, it is determined that there is no mapping relationship abnormality in the target node; wherein the first target node name is the node name in the current storage content of the logical storage unit corresponding to the target computing node; the second target node name is the node name of the computing node information of the corresponding target computing node in the node configuration information of the management node; the first target node identity identification number is the node identity identification number in the current storage content of the logical storage unit corresponding to the target computing node; the second target node identity identification number is the node identity identification number of the computing node information of the corresponding target computing node in the node configuration information of the management node; the target computing node is any computing node among all computing nodes;

[0083] If the name of the first target node is different from the name of the second target node or the first target node identity identification number is different from the second target node identity identification number, it is determined that there is a mapping relationship abnormality in the target node, and target node abnormality prompt information is output; the target node abnormality prompt information is used to characterize that there is a mapping relationship abnormality in the target node.

[0084] In this embodiment, by comparing the first target node name with the second target node name, and comparing the first target node identity identification number with the second target node identity identification number, it is possible to promptly discover mapping relationship anomalies in the target nodes, thereby facilitating management of the computing nodes.

[0085] It should be understood that although Figure 2-6 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders.
