Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer, in particular to a node mounting method and device, a computer device and a storage medium. BACKGROUND

[0002] With the development of information technology, distributed systems become mainstream. In distributed systems, there are many nodes, and the network protocol stack modes used by different nodes may differ, which can easily lead to data communication problems.

[0003] In related technologies, in the node mounting process, to avoid system crashes or data loss caused by inconsistent network protocol stack modes, manual intervention is used to perform consistency checking of the network protocol stack mode to ensure the safety of node mounting.

[0004] However, this manual intervention to perform consistency checking of the network protocol stack mode not only consumes time and effort, but also has a high probability of checking errors, which seriously affects the stability and reliability of the system. SUMMARY

[0005] Therefore, the present application provides a node mounting method and device, a computer device and a storage medium to solve the problem that manual intervention to perform consistency checking of the network protocol stack mode in related technologies not only consumes time and effort, but also has a high probability of checking errors, which seriously affects the stability and reliability of the system.

[0006] In a first aspect, the present application provides a node mounting method, which comprises:

[0007] In response to a scene selection operation, determining the current scene;

[0008] If the current scene is a first scene, receiving a mounting request sent by a node to be mounted;

[0009] Based on the mounting request, obtaining the network protocol stack configuration of the node to be mounted, and based on the network stack protocol configuration of the node to be mounted, generating network protocol stack mode description information of the node to be mounted;

[0010] Comparing the network protocol stack mode description information of the node to be mounted with the network protocol stack mode description information of the current cluster;

[0011] If the comparison result is that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster, it is determined that the node to be mounted is allowed to mount to the current cluster, and mounting information is sent to the node to be mounted, so that the node to be mounted receives the mounting information and mounts based on the mounting information.

[0012] The node mounting method provided in this embodiment receives a mounting request sent by the node to be mounted when the current scenario is the first scenario, obtains the network protocol stack configuration of the node to be mounted based on the mounting request, generates network protocol stack mode description information of the node to be mounted based on the network protocol stack configuration of the node to be mounted, automatically compares the network protocol stack mode description information of the node to be mounted with the network protocol stack mode description information of the current cluster, obtains a comparison result, and the comparison result is that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster, determines that the node to be mounted is allowed to be mounted to the current cluster, sends a mount permission information to the node to be mounted, so that the node to be mounted receives the mount permission information and performs mounting based on the mount permission information. This realizes that when the node is mounted, the consistency check of the network protocol stack mode is automatically performed, which not only saves time and manpower, but also has a high accuracy of the check, thereby improving the stability and reliability of the distributed system.

[0013] In an optional embodiment, the method further includes:

[0014] If the comparison result shows that the network protocol stack mode description information of the node to be mounted is inconsistent with the network protocol stack mode description information of the current cluster, it is determined that the node to be mounted is prohibited from mounting, and an error message indicating that the network protocol stack mode does not match is returned.

[0015] The node mounting method provided in this embodiment can effectively avoid system crashes or data loss caused by inconsistent network protocol stack modes by verifying whether the network protocol stack mode of the node to be mounted is consistent with the network protocol stack mode of the cluster before the node is mounted, thereby improving the security and reliability of distributed system mounting.

[0016] In an optional embodiment, the method further includes:

[0017] When the current scenario is the second scenario, receiving a mount request and a message for network protocol stack mode negotiation sent by the node to be mounted;

[0018] Based on the mount request sent by the node to be mounted, obtaining network protocol stack mode description information of the node to be mounted in the message for network protocol stack mode negotiation;

[0019] Compare the network protocol stack mode description information of the node to be mounted with the network protocol stack mode description information of the current cluster;

[0020] If the comparison result shows that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster, determine to allow the node to be mounted to be mounted to the current cluster, and send a mount permission message to the node to be mounted, so that the node to be mounted receives the mount permission message and performs the mount operation based on the mount permission message;

[0021] If the comparison result shows that the network protocol stack mode description information of the node to be mounted is inconsistent with the network protocol stack mode description information of the current cluster, determining whether the network protocol stack mode of the current cluster can be adjusted to be consistent with the network protocol stack mode of the node to be mounted;

[0022] When the network protocol stack mode of the current cluster can be adjusted to be consistent with the network protocol stack mode of the node to be mounted, a mount permission information is sent to the node to be mounted, and the network protocol stack mode of the current cluster is adjusted to be consistent with the network protocol stack mode of the node to be mounted, so that the node to be mounted receives the mount permission information and performs mounting based on the mount permission information.

[0023] The node mounting method provided in this embodiment adjusts the network protocol stack mode of the current cluster if the network protocol stack mode of the node to be mounted is inconsistent with the network protocol stack mode of the current cluster when the current scenario is the second scenario. If the network protocol stack mode of the current cluster can be adjusted to be consistent with the network protocol stack mode of the node to be mounted, the node to be mounted is allowed to be mounted, and the network protocol stack mode of the current cluster is adjusted to be consistent with the network protocol stack mode of the node to be mounted. This ensures that the new node can still be mounted to the cluster through negotiation under different network protocol stack modes, thereby improving the adaptability, flexibility, and scalability of the system.

[0024] In an optional embodiment, the method further includes:

[0025] When the network protocol stack mode of the current cluster cannot be adjusted to be consistent with the network protocol stack mode of the node to be mounted, a mount prohibition message is sent to the node to be mounted, and the mount request of the node to be mounted is rejected.

[0026] The node mounting method provided in this embodiment rejects the mounting request of the node to be mounted if the network protocol stack mode of the current cluster cannot be adjusted to be consistent with the network protocol stack mode of the node to be mounted, thereby avoiding system crashes or data loss caused by inconsistent network protocol stack modes and improving the security and reliability of distributed system mounting.

[0027] In an optional embodiment, the method further includes:

[0028] Real-time monitoring of the process of mounting the node to be mounted;

[0029] If an exception occurs during the mounting process of the node to be mounted, obtain the exception information;

[0030] Based on the abnormal information, the mounting status of the node to be mounted is determined.

[0031] The node mounting method provided in this embodiment can detect and capture abnormalities in the mounting operation as soon as they occur through a real-time monitoring mechanism, greatly shortening the time window for fault monitoring and improving maintenance efficiency.

[0032] In an optional implementation, determining the mounting status of the node to be mounted based on the abnormal information includes:

[0033] If the abnormality level indicated by the abnormal information is the first level, immediately stop the mounting of the node to be mounted, and determine the mounting state of the node to be mounted as stopped mounting;

[0034] When the abnormality level indicated by the abnormal information is the second level, continuing to mount the node to be mounted, and determining the mounting state of the node to be mounted to continue mounting;

[0035] The first level of abnormality is higher than the second level of abnormality.

[0036] The node mounting method provided in this embodiment achieves refined management of exceptions during the mounting process by distinguishing the degree of exceptions that occur during the mounting process and adopting different mounting strategies for exceptions of different levels. This not only avoids unnecessary mounting terminations, but also ensures that serious exceptions are contained in a timely manner, thereby enhancing the adaptability and robustness of the system.

[0037] In an optional embodiment, the method further includes:

[0038] If an exception occurs during the mounting process of the node to be mounted, the exception information is recorded in a log so that the user can analyze the cause of the exception based on the log, wherein the exception information includes the level of the exception.

[0039] The node mounting method provided in this embodiment provides a basis for subsequent analysis by recording abnormal information in a log. Users or operation and maintenance personnel can quickly trace the scene and cause of the abnormality based on the abnormal information in the log, which helps to quickly locate and resolve the abnormality and improve maintenance efficiency.

[0042] A first receiving module is configured to receive a mount request sent by a node to be mounted when the current scenario is the first scenario;

[0043] A first acquisition module is configured to acquire, based on the mount request, a network protocol stack configuration of the node to be mounted, and generate network protocol stack mode description information of the node to be mounted based on the network stack protocol configuration of the node to be mounted;

[0044] A first comparison module is used to compare the network protocol stack mode description information of the node to be mounted with the network protocol stack mode description information of the current cluster;

[0045] The second determination module is used to determine that the node to be mounted is allowed to be mounted to the current cluster when the comparison result shows that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster, and send a mount permission information to the node to be mounted, so that the node to be mounted receives the mount permission information and performs mounting based on the mount permission information.

[0055] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0056] With the development of information technology, distributed systems have become the mainstream of system design and implementation. Distributed systems have numerous nodes and complex environments, and different nodes may use different network protocol stack models, leading to numerous problems in data communication. A network protocol stack refers to the layered set of protocols used in network communications—a set of rules and standards that ensures reliable data transmission between computing devices. A network protocol stack is typically divided into multiple layers, with each layer handling specific tasks in the communication process.

[0057] In related technologies, when a node is mounted to a distributed cluster, if the network protocol stack mode of the node is inconsistent with the network protocol stack mode of the distributed cluster, it will cause the distributed system to crash or data to be lost, seriously affecting the stability and reliability of the system.

[0058] To prevent system crashes or data loss caused by inconsistent network protocol stack models, related technologies use manual intervention to perform consistency checks on the network protocol stack model to ensure the security of node mounting. Consistency checks are used to ensure the consistency and correctness of data within the system, preventing data failures or anomalies due to errors, conflicts, or mismatches. Consistency checks are widely used in database systems, distributed systems, file systems, and other scenarios where data accuracy must be ensured.

[0059] However, this method of manually intervening in consistency verification of the network protocol stack mode is not only time-consuming and labor-intensive, but also has a high probability of verification errors, which seriously affects the stability and reliability of the system.

[0060] An embodiment of the present invention provides a node mounting method, which performs consistency verification of the network protocol stack mode through the current scenario. When the current scenario is the first scenario, if it is detected that the network protocol stack mode of the node to be mounted is inconsistent with the network protocol stack mode of the current cluster, the node to be mounted is prohibited from mounting. When the current scenario is the second scenario, if it is detected that the network protocol stack mode of the node to be mounted is inconsistent with the network protocol stack mode of the current cluster, the network protocol stack mode of the current cluster is adjusted. When the network protocol stack mode of the current cluster can be adjusted to be consistent with the network protocol stack mode of the node to be mounted, the node to be mounted is allowed to be mounted, so as to achieve the effect of automatically performing consistency verification of the network protocol stack mode, saving time and manpower, improving verification accuracy, and improving the stability and reliability of the distributed system.

[0061] According to an embodiment of the present invention, an embodiment of a node mounting method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0062] In this embodiment, a node mounting method is provided, which can be used in a distributed system. Figure 1 is a flowchart of a node mounting method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0063] Step S101: In response to a scene selection operation, determine the current scene.

[0064] Among them, the user determines the current scenario based on the current network environment and changes in the network protocol stack mode, and then selects the corresponding scenario.

[0065] It should be noted that a tool capable of identifying and analyzing node network protocol stack patterns is deployed in a distributed cluster environment. This tool has efficient identification capabilities and accurate analysis functions.

[0066] It is understandable that the node mounting method of this embodiment relies on the accuracy and efficiency of the tool. Deploying and calling the tool uniformly on all nodes may increase the management and maintenance workload.

[0067] Step S102: When the current scenario is the first scenario, a mount request sent by the node to be mounted is received.

[0068] The first scenario is a scenario in which a network environment is relatively stable and a network protocol stack mode changes less.

[0069] When the node attempts to mount to the cluster, the node sends a mounting request to the distributed system, and the distributed system receives the mounting request sent by the node to be mounted.

[0070] In step S103, based on the mounting request, the network protocol stack configuration of the node to be mounted is obtained, and based on the network stack protocol configuration of the node to be mounted, network protocol stack mode description information of the node to be mounted is generated.

[0071] After receiving the mounting request sent by the node to be mounted, the above-mentioned deployed tool is automatically called to perform pre-detection of the network protocol stack mode.

[0072] Specifically, the tool is used to read the network protocol stack configuration of the node to be mounted, and based on the network protocol stack configuration of the node to be mounted, network protocol stack mode description information of the node to be mounted is generated.

[0073] In step S104, the network protocol stack mode description information of the node to be mounted is compared with the network protocol stack mode description information of the current cluster.

[0074] The network protocol stack mode description information of the node to be mounted is compared with the network protocol stack mode description information of the current cluster by using the above-mentioned tool, to determine whether the network protocol stack mode of the node to be mounted is consistent with the network protocol stack mode of the current cluster.

[0075] It should be noted that the network protocol stack modes of the nodes in the cluster are consistent.

[0076] In step S105, in the case that the comparison result is that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster, it is determined that the node to be mounted is allowed to mount to the current cluster, and mounting permission information is sent to the node to be mounted, so that the node to be mounted receives the mounting permission information and mounts based on the mounting permission information.

[0077] The comparison result is that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster, which means that the network protocol stack mode of the node to be mounted is consistent with the network protocol stack mode of the current cluster, the pre-detection is passed, and the node to be mounted is allowed to mount to the current cluster.

[0078] In the case that the pre-detection is passed, mounting permission information is sent to the node to be mounted, so that the node to be mounted receives the mounting permission information and continues the mounting process based on the mounting permission information.

[0079] The node mounting method provided in this embodiment receives a mounting request sent by the node to be mounted when the current scenario is the first scenario, obtains the network protocol stack configuration of the node to be mounted based on the mounting request, generates network protocol stack mode description information of the node to be mounted based on the network protocol stack configuration of the node to be mounted, automatically compares the network protocol stack mode description information of the node to be mounted with the network protocol stack mode description information of the current cluster, obtains a comparison result, and the comparison result is that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster, determines that the node to be mounted is allowed to be mounted to the current cluster, sends a mount permission information to the node to be mounted, so that the node to be mounted receives the mount permission information and performs mounting based on the mount permission information. This realizes that when the node is mounted, the consistency check of the network protocol stack mode is automatically performed, which not only saves time and manpower, but also has a high accuracy of the check, thereby improving the stability and reliability of the distributed system.

[0080] In this embodiment, a node mounting method is provided, which can be used in a distributed system. Figure 2 is a flowchart of a node mounting method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0081] Step S201: In response to the scene selection operation, determine the current scene. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0082] Step S202: When the current scenario is the first scenario, a mount request is received from the node to be mounted. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0083] Step S203: Based on the mount request, obtain the network protocol stack configuration of the node to be mounted, and generate the network protocol stack mode description information of the node to be mounted based on the network stack protocol configuration of the node to be mounted. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0084] Step S204: Compare the network protocol stack mode description information of the node to be mounted with the network protocol stack mode description information of the current cluster. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0085] Step S205, in the case that the comparison result is that the network protocol stack mode description information of the to-be-mounted node is consistent with the network protocol stack mode description information of the current cluster, it is determined that the to-be-mounted node is allowed to mount to the current cluster, and the to-be-mounted node is sent the mounting permission information, so that the to-be-mounted node receives the mounting permission information and mounts based on the mounting permission information. For details, please refer to Figure 1 Step S105 of the embodiment shown will not be described here again.

[0086] Step S206, in the case that the comparison result is that the network protocol stack mode description information of the to-be-mounted node is inconsistent with the network protocol stack mode description information of the current cluster, it is determined that the to-be-mounted node is prohibited from mounting, and error information of network protocol stack mode mismatch is returned.

[0087] The comparison result that the network protocol stack mode description information of the to-be-mounted node is inconsistent with the network protocol stack mode description information of the current cluster indicates that the network protocol stack mode of the to-be-mounted node is inconsistent with the network protocol stack mode of the current cluster, the pre-detection fails, the to-be-mounted node is prohibited from mounting to the current cluster, the mounting operation of the to-be-mounted node is terminated, and detailed error information is returned to prompt the network protocol stack mode mismatch.

[0088] It should be noted that the error information can be provided to a technician or administrator for further diagnosis and problem solving.

[0089] The node mounting method provided in this embodiment can effectively avoid system crashes or data loss caused by inconsistent network protocol stack modes and improve the security and reliability of distributed system mounting by verifying whether the network protocol stack mode of the to-be-mounted node is consistent with the network protocol stack mode of the cluster before mounting.

[0090] The node mounting method provided in this embodiment can discover and prevent potential problems in time before mounting by pre-detecting before actual mounting, avoid frequent mounting errors caused by inconsistent network protocol stack modes, and thus ensure the stability of the entire distributed cluster and the security of data transmission. In particular, in a large-scale cluster environment, the node mounting method can significantly reduce the complexity and workload of system maintenance and improve the work efficiency of administrators.

[0091] In some optional embodiments, the above node mounting method further includes:

[0092] Step a1, in the case that the current scenario is a second scenario, receiving the mounting request and the message for network protocol stack mode negotiation sent by the to-be-mounted node.

[0093] The second scenario is a scenario in which the network environment is complex and the network protocol stack mode can change dynamically.

[0094] Figure 3 FIG. 1 is a flow chart of node mounting in the second scenario according to an embodiment of the present invention. Figure 3 As shown in the figure, in the second scenario, when a node attempts to mount, it sends a mount request and a special message for network protocol stack mode negotiation to the distributed system. That is, the node to be mounted pre-sends a negotiation message to the distributed cluster. The distributed system receives the mount request and the message for network protocol stack mode negotiation sent by the node to be mounted.

[0095] It should be noted that the format and content of the message used for network protocol stack mode negotiation can describe the current network protocol stack mode of the node to be mounted.

[0096] Step a2: Based on the mount request sent by the node to be mounted, obtain the network protocol stack mode description information of the node to be mounted in the message used for network protocol stack mode negotiation.

[0097] Among them, after receiving the mounting request sent by the node to be mounted and the message for network protocol stack mode negotiation, in response to the mounting request sent by the node to be mounted, the message for network protocol stack mode negotiation is parsed to obtain the network protocol stack mode description information of the node to be mounted, that is, the negotiation request is received.

[0098] Step a3: Compare the network protocol stack mode description information of the node to be mounted with the network protocol stack mode description information of the current cluster.

[0099] After obtaining the network protocol stack mode description information of the node to be mounted, the network protocol stack mode description information of the node to be mounted is compared with the network protocol stack mode description information of the current cluster, that is, analyzing whether the modes match.

[0100] Step a4, when the comparison result shows that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster, determine that the node to be mounted is allowed to be mounted to the current cluster, and send a mount permission information to the node to be mounted, so that the node to be mounted receives the mount permission information and performs mounting based on the mount permission information.

[0101] Among them, in the second scenario, the detailed description of the comparison result that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster is the same as the detailed description of the comparison result that the network protocol stack mode description information of the node to be mounted is consistent with the network protocol stack mode description information of the current cluster in the first scenario, and will not be repeated here.

[0102] Step a5, in the case that the comparison result is that the network protocol stack mode description information of the to-be-mounted node is inconsistent with the network protocol stack mode description information of the current cluster, it is judged whether the network protocol stack mode of the current cluster can be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node.

[0103] In the second scenario, if the comparison result is that the network protocol stack mode description information of the to-be-mounted node is inconsistent with the network protocol stack mode description information of the current cluster, negotiation is needed, that is, the mode is adjusted to match the network protocol stack mode of the to-be-mounted node.

[0104] It is judged whether the network protocol stack mode of the current cluster can be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, that is, whether the network protocol stack mode of the current cluster can be successfully adjusted to be consistent with the network protocol stack mode of the to-be-mounted node.

[0105] Step a6, in the case that the network protocol stack mode of the current cluster can be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, the to-be-mounted node is sent the mounting permission information, and the network protocol stack mode of the current cluster is adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, so that the to-be-mounted node receives the mounting permission information and mounts based on the mounting permission information.

[0106] In the case that the network protocol stack mode of the current cluster can be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, it indicates that the to-be-mounted node can be mounted to the current cluster, the to-be-mounted node is sent the mounting permission information, that is, the negotiation result, the negotiation result is that the mode is matched and the mounting is allowed, indicating that the mounting operation continues, and the network protocol stack mode of the current cluster is adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, so as to realize the mounting of the to-be-mounted node.

[0107] The node mounting method provided in the embodiment adjusts the network protocol stack mode of the current cluster if the network protocol stack mode of the to-be-mounted node is inconsistent with the network protocol stack mode of the current cluster in the case that the current scenario is the second scenario, allows the to-be-mounted node to mount in the case that the network protocol stack mode of the current cluster can be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, and adjusts the network protocol stack mode of the current cluster to be consistent with the network protocol stack mode of the to-be-mounted node. It is ensured that the new node can be mounted to the cluster through negotiation under different network protocol stack modes, and the adaptability, flexibility and expansibility of the system are improved.

[0108] The node mounting method provided by the embodiment of the application is more flexible and dynamic in the case that the current scenario is the second scenario, i.e., the network protocol stack mode may be affected by dynamic factors, based on the newly added message for network protocol stack mode negotiation, allows the node to perform real-time mode confirmation and adjustment during the mounting process, to achieve the consistency of the network protocol stack mode, and can adapt to complex and variable network environments. For example, in some scenarios where the network protocol stack mode may be dynamically adjusted by external environment or internal strategy, the node mounting method can effectively solve the mounting problem caused by different network protocol stack modes, and improve the adaptability and flexibility of the system.

[0109] It should be noted that in the second scenario, it is necessary to ensure that all nodes can normally parse and respond to the message for network protocol stack mode negotiation, and at the same time, the node needs to have certain adaptive adjustment capability, which may have higher requirements for the hardware and software of the system.

[0110] In some optional embodiments, the node mounting method further includes:

[0111] In the case that the network protocol stack mode of the current cluster cannot be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, the to-be-mounted node is sent the mounting prohibition information, and the mounting request of the to-be-mounted node is rejected.

[0112] In the case that the network protocol stack mode of the current cluster cannot be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, it means that the adjustment of the network protocol stack mode of the current cluster fails or cannot be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, the to-be-mounted node is prohibited from mounting, the mounting prohibition information is sent to the to-be-mounted node, i.e., the negotiation result is fed back, the negotiation result is that the mounting fails due to mismatch, and the mounting request of the to-be-mounted node is rejected.

[0113] It should be noted that in the case that the network protocol stack mode of the current cluster cannot be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node, the error information of the mismatch of the network protocol stack mode is returned, and the mounting is prohibited.

[0114] The node mounting method provided by the embodiment avoids system crash or data loss caused by inconsistent network protocol stack modes, and improves the security and reliability of the mounting of the distributed system, by rejecting the mounting request of the to-be-mounted node in the case that the network protocol stack mode of the current cluster cannot be adjusted to be consistent with the network protocol stack mode of the to-be-mounted node.

[0115] In some optional embodiments, the node mounting method further includes:

[0116] Step c1, the process of mounting the to-be-mounted node is monitored in real time.

[0117] Wherein, when the node to be mounted is allowed to be mounted to the current cluster and the node to be mounted is mounted, the mounting process of the node to be mounted is monitored in real time.

[0118] Step c2: If an exception occurs during the mounting process of the node to be mounted, obtain the exception information.

[0119] During the process of mounting the node to be mounted, if an exception is detected, the exception information corresponding to the exception is obtained.

[0120] Step c3: Determine the mounting status of the node to be mounted based on the abnormal information.

[0121] After the abnormal information is obtained, the mounting status of the node to be mounted is determined according to the abnormal information, that is, whether to continue mounting or stop mounting.

[0122] The node mounting method provided in this embodiment can detect and capture abnormalities in the mounting operation as soon as they occur through a real-time monitoring mechanism, greatly shortening the time window for fault monitoring and improving maintenance efficiency.

[0123] In some optional implementations, the above step c3 includes:

[0124] Step c31: when the abnormality level indicated by the abnormality information is the first level, immediately stop the mounting of the node to be mounted, and determine that the mounting state of the node to be mounted is stopped.

[0125] Among them, the first level is the serious exception level. The first level of the exception indicates that the exception will seriously affect the system. In this case, it is necessary to stop the mounting of the node to be mounted. After resolving the serious exception, the mounting of the node to be mounted can be continued.

[0126] Step c32: When the abnormality level indicated by the abnormality information is the second level, continue mounting the node to be mounted, and determine that the mounting state of the node to be mounted is to continue mounting.

[0127] Among them, the abnormality level of the first level is higher than the abnormality level of the second level.

[0128] Among them, the second level is the general exception level. The exception level is the second level, which indicates that the exception will hardly affect the system. In this case, the mounting of the node to be mounted will continue. After the mounting is completed, return to handle the exception.

[0129] The node mounting method provided in this embodiment achieves refined management of exceptions during the mounting process by distinguishing the degree of exceptions that occur during the mounting process and adopting different mounting strategies for exceptions of different levels. This not only avoids unnecessary mounting terminations, but also ensures that serious exceptions are contained in a timely manner, thereby enhancing the adaptability and robustness of the system.

[0130] In some optional implementations, the node mounting method further includes:

[0131] In step d1, if an exception occurs during the mounting process of the node to be mounted, the exception information is recorded in a log so that the user can analyze the cause of the exception based on the log. The exception information includes the level of the exception.

[0132] When an exception occurs during the mounting process of the node to be mounted, a log is recorded to facilitate rapid location of the exception.

[0133] Users can adopt different optimization strategies based on frequently occurring low-level exceptions or occasionally occurring high-level exceptions to continuously improve the mounting process and enhance system robustness.

[0134] The node mounting method provided in this embodiment provides a basis for subsequent analysis by recording abnormal information in a log. Users or operation and maintenance personnel can quickly trace the scene and cause of the abnormality based on the abnormal information in the log, which helps to quickly locate and resolve the abnormality and improve maintenance efficiency.

[0135] In some optional implementations, the node mounting method further includes:

[0136] When the node to be mounted is allowed to be mounted to the current cluster, the data of the current cluster is backed up so that if an exception occurs during the mounting of the node to be mounted and the level of the exception is the first level, data recovery is performed based on the backup data of the current cluster.

[0137] The node mounting method provided in this embodiment can perform data recovery in the event of a serious abnormality when the node to be mounted is mounted to the current cluster by backing up the data of the current cluster, thereby reducing the risk of data loss and improving the stability and fault tolerance of the system in the face of abnormal situations.
