[0041] The computing node working status detection method provided in this application can be applied to, for example... Figure 1 In the application environment shown, the physical host system 102 communicates with the storage system 104 via a network or input / output ports. 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, such as Figure 2 As shown, a method for detecting the working state of a computing node is provided, which can be applied to... Figure 1 The following steps are used as an example of physical host system 102, including steps 201 to 204.

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

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

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

[0046] In one embodiment, such as 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 the logical storage unit of the corresponding storage area network in the 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 can create each logical storage unit according to the storage unit creation instruction and generate and send a node connection mapping list to the physical host system.

[0048] Specifically, the physical host system 102 sends a storage unit creation instruction to the storage system, so that the storage system can create each logical storage unit according to the storage unit creation instruction, generate and send 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 / output interface mode, a Storage Area Network (SAN) provides logical unit numbers (LUNs) for management and compute nodes. All nodes in the server cluster can access the same LUN provided by the SAN, with a minimum LUN capacity of 1 MiB. The LUN is divided into 2048 blocks of 512B each, and each node in the server cluster corresponds to one block on the LUN. Therefore, cluster management supports a minimum of 2048 nodes. Each node in the cluster is assigned a unique identity document (ID) and a unique node name. The node ID ranges from 0 to 2047. A node with an ID value of i can only access the i-th block on the LUN. This is just a specific example; in actual applications, it can be flexibly configured according to user needs, and no restrictions are imposed here.

[0050] In this embodiment, a storage unit creation instruction is issued to the storage system, so that the storage system can create each logical storage unit according to the storage unit creation instruction, generate and send 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 the configuration operation for each node, generate the configuration information of the node, and configure the corresponding node according to the node configuration information.

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

[0053] In one embodiment, such as Figure 4 As shown, in response to the configuration operation of each node, configuration information of the node is generated, and the corresponding node is configured according to the node configuration information, including steps 401 and 402.

[0054] Step 401: In response to the configuration operation of the management node, generate the first absolute path information of the logical storage unit corresponding to the management node, the computing node information of each computing node, the logical storage unit read interval of the management node, the logical storage unit write interval of the management node, and the working mode.

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

[0056] The compute node information includes the corresponding Internet Protocol Address (IP), node identification number, and node name; the operating mode is input / output interface operating mode; the node configuration information for the management node includes the first absolute path information, information for each compute node, logical storage unit read interval time, logical storage unit write interval time, and operating mode. Furthermore, the operating mode can also be set to network mode.

[0057] Specifically, when the physical host system 102 detects a configuration operation on the 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 logical storage unit read interval time of the management node, the logical storage unit write interval time and working mode of the management node; then, it configures the corresponding management node according to the node configuration information of the management node, thereby improving the efficiency and convenience of the management node configuration.

[0058] In this embodiment, in response to the configuration operation of the 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 logical storage unit read interval time of the management node, the logical storage unit write interval time and working mode of the management node are generated; then, the corresponding management node is configured according to the node configuration information of the management node, which improves the efficiency and convenience of the management node configuration.

[0059] In one embodiment, such as Figure 4 As shown, in response to the configuration operation of each node, the configuration information of the node is generated, and the corresponding node is configured according to the node configuration information, and steps 403 and 404 are also included.

[0060] Step 403: In response to the configuration operation of each computing node, the second absolute path information of the logical storage unit corresponding to the computing node, the node identification number of the corresponding computing node, and the node name of the corresponding computing node are generated.

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

[0062] The configuration information for each computing node includes the corresponding second absolute path information, the computing node information, and the node name. Specifically, when the physical host system 102 detects a configuration operation on each computing node, it generates the second absolute path information of the logical storage unit corresponding to the computing node, the node identification number of the computing node, and the node name of the computing node. Then, it configures the corresponding computing node according to the node configuration information, thereby improving the efficiency and convenience of computing node configuration.

[0063] In this embodiment, in response to the configuration operation of each computing node, 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 are generated; then, the corresponding computing node is configured according to the node configuration information of each computing node, which improves the efficiency and convenience of computing node configuration.

[0064] Step 203: In response to the management node's working mode being input / output interface working mode, start-up operations are performed on each node, controlling each computing node to periodically update the corresponding logical storage unit, and controlling the management node to read the current storage content of each logical storage unit.

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

[0066] In one embodiment, such as Figure 5 As shown, in response to the management node's working mode being the input / output interface working mode, the node is started, each computing node is controlled to update its corresponding logical storage unit periodically, 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's working mode being input / output interface working mode, start-up operation is performed on each node. Based on the logical storage unit write interval, each computing node is controlled to periodically update the corresponding logical storage unit, 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 current stored content includes the node identification number of the corresponding computing node, the node name of the corresponding computing node, the updated content of the corresponding computing node, and the content update timestamp of the corresponding computing node.

[0070] Specifically, when the physical host system 102 identifies that the management node is in input / output interface mode, it starts each node and controls each computing node to update its corresponding logical storage unit periodically according to the logical storage unit write interval, 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 logical storage unit read interval, 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 management node's working mode being the input / output interface working mode, each node is started. Based on the logical storage unit write interval, each computing node is controlled to periodically update the corresponding logical storage unit, and the standard update write time of each computing node is recorded. Then, based on the logical storage unit read interval, the management node is controlled to read the current storage content of each corresponding 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 based on the current storage content of each logical storage unit.

[0073] The working status includes normal operation or abnormal operation. Specifically, the physical host system 102 determines the working status of the corresponding computing node based on the current storage content of each logical storage unit, thereby avoiding misjudgment of detection results due to network connection failures between the management node and the computing node, reducing system complexity, improving system availability, maintainability and cluster management flexibility, reducing costs, and improving the accuracy and real-time performance of computing node working status detection.

[0074] Based on this, the aforementioned compute node working status detection method, in response to receiving a node connection mapping list sent by the storage system, controls each node to establish a connection with the logical storage unit of the corresponding storage area network in the storage system according to the node connection mapping list; the nodes include management nodes and each compute node; then, in response to performing configuration operations on each node, generating node configuration information, and configuring the corresponding node according to the node configuration information; next, in response to the management node's working mode being input / output interface working mode, starting each node, controlling each compute node to periodically update the corresponding logical storage unit, and controlling the management node to read the current storage content of each logical storage unit; finally, judging the working status of the corresponding compute node based on the current storage content of each logical storage unit, thereby avoiding misjudgment of detection results due to network connection failure between the management node and compute nodes, reducing system complexity, improving system availability, maintainability and cluster management flexibility, reducing costs, and improving the accuracy and real-time performance of compute node working status detection.

[0075] In one embodiment, such as Figure 6 As shown, the working status of the corresponding computing node is determined based on the current storage content of each logical storage unit, including steps 601 to 603.

[0076] Step 601: Determine whether the content update timestamp of the corresponding compute node in each current storage content is the same as the standard update write time of the corresponding compute node;

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

[0078] Step 603: If they are not the same, then determine that the working status 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 current storage content is the same as the standard update write time of the corresponding computing node; then, if they are the same, the working status of the corresponding computing node is determined to be normal; then, if they are not the same, the working status of the corresponding computing node is determined to be abnormal, thereby improving the efficiency and accuracy of judging the working status of computing nodes.

[0080] In this embodiment, it is determined whether the content update timestamp of the corresponding computing node in each current storage content is the same as the standard update write time of the corresponding computing node; then, if they are the same, the working status of the corresponding computing node is determined to be normal; then, if they are not the same, the working status of the corresponding computing node is determined to be abnormal, thereby improving the efficiency and accuracy of judging the working status of computing nodes.

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

[0082] If the name of the first target node is the same as the name of the second target node and the identification number of the first target node is the same as the identification number of the second target node, it is determined that there is no abnormal mapping relationship between the target nodes;

[0083] 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 in the computing node information of the target computing node corresponding to the node configuration information of the management node; the first target node identification number is the node identification number in the current storage content of the logical storage unit corresponding to the target computing node; the second target node identification number is the node identification number in the computing node information of the target computing node corresponding to the node configuration information of the management node; the target computing node is any computing node among all computing nodes;

[0084] If the name of the first target node is different from the name of the second target node, or if the identification number of the first target node is different from the identification number of the second target node, it is determined that there is an abnormal mapping relationship between the target nodes, and an abnormal target node prompt message is output; the abnormal target node prompt message is used to indicate that there is an abnormal mapping relationship between the target nodes.

[0085] In this embodiment, by comparing the first target node name with the second target node name, and by comparing the first target node identification number with the second target node identification number, abnormal mapping relationships of target nodes can be detected in a timely manner, which facilitates the management of computing nodes.

[0086] It should be understood that, although Figure 2-6 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. Figure 2-6 At least some of the steps in the process may include multiple sub-steps or multiple stages. 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.

[0091] In one embodiment, the node connection unit is also used to issue 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.

[0092] In one embodiment, the node configuration module 720 includes a node configuration unit.
