Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, device, equipment and storage medium for processing node pseudo-death. Background Art

[0002] The suspended state of a node refers to a situation where the computer operating system is running but temporarily does not respond to user operations. Suspended state is a common failure phenomenon that may be encountered when using a computer. It is different from a complete system freeze. In the suspended state, the basic input and output system can still work, but the node's response will be significantly slowed down or seem to be completely unresponsive, usually lasting from a few seconds to a few minutes.

[0003] In the prior art, the acquisition of the suspended state is usually processed by the watchdog mode, that is, at regular intervals, the node sends a signal to the dog feeding end, thereby resetting the watchdog timer. If the node fails, such as entering an endless loop that cannot be exited, resulting in failure to "feed the dog" within the specified time, the watchdog timer will time out, and send a reset signal to reset the MCU (Microcontroller Unit, micro control unit), thereby restoring the normal operation of the node, but this method can usually only be triggered when the operating system level is on the verge of collapse. Because the priority of the watchdog is very high, there will be a lot of abnormal situations, that is, the operating system can also feed the dog normally, and it is unlikely to trigger the watchdog to restart the system, but the situation that the storage service of the node cannot run normally due to hardware or software failure. At this time, due to the suspended state of individual nodes, the storage service performance is greatly reduced, and it is even possible that the storage service cannot be normally provided, and the storage service will usually be affected for a long time, causing serious adverse consequences.

[0004] Therefore, in view of the shortcomings of the prior art solutions, the present invention provides a method for processing node pseudo-death. Summary of the invention

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0026] In one embodiment, Figure 1 As shown, a method for processing a node suspended state is provided, comprising the following steps:

[0027] S101: Detecting hardware operating parameters and node load of a node, wherein the hardware operating parameters include operating parameters of each hardware and operating parameters between hardware.

[0028] Here, a node may include multiple hardware and, accordingly, multiple hardware operation parameters. For example, a node includes a CPU (Central Processing Unit), a memory, and a network card.

[0029] When a node includes a CPU, a memory, and a network card, the operating parameters of each hardware may be, for example, the operating parameters of the CPU, and the operating parameters between the hardware may be, for example, the operating parameters between the CPU and the memory.

[0030] S102: Determine whether the node is in a suspended state according to the hardware operating parameters of the node and / or the node load.

[0031] Here, the suspended state is a state of temporarily stopping response.

[0032] In one embodiment, it is possible to determine whether the node is in a suspended state based on one hardware operating parameter, or it is possible to determine whether the node is in a suspended state based on all hardware operating parameters of the node.

[0033] S103: When it is determined that the node is in a suspended state, close the network port corresponding to the node.

[0034] Here, one node can correspond to one network port, and one node can also correspond to multiple network ports. When the node is in a suspended state, all network ports corresponding to the node are closed.

[0035] S104: Acquire a high-availability service corresponding to the node, and cut off the storage service corresponding to the node through the high-availability service.

[0036] Here, high-availability services refer to services that can continue to run even when a node fails.

[0037] It should be noted that the present application collects and analyzes the hardware status of the node. When it is found that the hardware is in a certain state that may cause the node to freeze, or the node load value at the operating system level is obviously abnormal and exceeds the threshold, the node's network port is immediately closed, thereby triggering the high-availability service achieved through network heartbeat detection to quickly failover the storage service, thereby quickly handling the node's frozen failure.

[0038] In some specific implementations, the hardware operating parameters and node load of the detection node include:

[0039] Determine the polling instruction corresponding to the node according to the hardware configuration of the node;

[0040] The hardware operating parameters and node load of the node are detected through the polling instruction.

[0041] Here, a time interval may be preset for the polling instruction, and the polling instruction sends the detection instruction on time according to the time interval.

[0042] The polling instructions include instructions for detecting operating parameters of each hardware of the node, instructions for detecting operating parameters between hardware, and instructions for detecting node load.

[0043] In this way, corresponding polling instructions can be designed according to the actual situation of the node to improve the detection efficiency.

[0044] In some specific implementations, judging whether the node is in a suspended state according to the hardware operating parameters of the node and / or the node load includes:

[0045] Recording the historical hardware operating parameters and historical node load of the node;

[0046] Whether the node is in a suspended state is determined according to at least one of a historical hardware operating parameter of the node, a current hardware operating parameter, a historical node load, and a current node load.

[0047] Here, the historical hardware operating parameters and the historical node loads may be multiple groups of historical hardware operating parameters and multiple historical node load values.

[0048] Among them, there may be a situation where the node is determined to be suspended by the current hardware operating parameters, there may be a situation where the node is determined to be suspended by the current hardware operating parameters and historical hardware operating parameters, there may be a situation where the node is determined to be suspended by the current node load, including but not limited to the above combinations.

[0049] In this way, by detecting the hardware status and load of the node, the pseudo-death state of the node that cannot be identified by the watchdog method can be identified.

[0050] In some specific implementations, judging whether the node is in a suspended state according to the hardware operating parameters of the node and / or the node load includes:

[0051] Obtaining hardware operating parameters of the node and determining the hardware status of each hardware in the node;

[0052] When detecting that hardware in an abnormal state exists in the node, determining that the node is in a suspended state;

[0053] If each hardware of the node is in a normal state, the node load of the node is obtained, and when it is detected that the node load of the node is in an abnormal state, it is determined that the node is in a suspended state.

[0054] Here, whether the target hardware is abnormal is determined by detecting the operating parameters of the target hardware and the operating parameters between the target hardware and other hardware.

[0055] Specifically, each hardware in the node is detected in turn to see if it is in an abnormal state. When it is detected that some hardware is in an abnormal state, the node is determined to be in a suspended state. If all the hardware of the node is in a normal state, the node load is detected. When it is detected that the node load is in an abnormal state, the node is determined to be in a suspended state.

[0056] In one embodiment, when it is detected in sequence that any hardware in the node is in an abnormal state, the detection is terminated and it is determined that the node is in a suspended state.

[0057] In this way, the abnormality of any indicator can be used to determine the suspended state of the node, thereby improving the detection efficiency.

[0058] In some specific implementations, obtaining the hardware operating parameters of the node and determining the hardware status of each hardware in the node includes:

[0059] Acquire current operating parameters of the central processing unit, determine whether the central processing unit is in a first abnormal state of the central processing unit, and when the central processing unit is not in the first abnormal state of the central processing unit and the current operating parameters are abnormal, acquire historical operating parameters of the central processing unit, and determine whether the central processing unit is in a second abnormal state of the central processing unit according to the historical operating parameters and the current operating parameters of the central processing unit;

[0060] When the central processing unit is in a normal state, obtaining current operating parameters and historical operating parameters of the memory, and judging whether the memory is in a memory abnormal state according to the current operating parameters and historical operating parameters of the memory;

[0061] When the memory is in a normal state, obtaining current operating parameters of the disk to determine whether the disk is in an abnormal disk state;

[0062] When the disk is in a normal state, obtaining current operating parameters of the network card to determine whether the network card is in an abnormal state;

[0063] When the network card is in a normal state, the current operating parameters of the link are obtained to determine whether the link is in a first abnormal state of the link; when the link is not in the first abnormal state of the link and the current operating parameters are abnormal, the historical operating parameters of the link are obtained, and according to the historical operating parameters and the current operating parameters of the link, it is determined whether the link is in a second abnormal state of the link, wherein the link is a link between the hardware of the nodes.

[0064] Here, the CPU has abnormal states that are judged based on the current operating parameters and abnormal states that are judged based on the current operating parameters and historical operating parameters. For example, the CPU stuck abnormality can be judged by the current operating parameters, and the CPU instruction abnormality is to obtain the historical operating parameters corresponding to the CPU when the CPU is detected to have an instruction abnormality, and judge whether the CPU has an instruction abnormality in the historical operating parameters. If the instruction abnormality occurs for a preset number of consecutive times, the node is judged to be in a suspended state, where the preset number can be three times or any other number.

[0065] Exemplarily, the first abnormal state of the central processing unit may be a CPU stuck abnormality, and the second abnormal state of the central processing unit may be a CPU instruction abnormality; the abnormal state of the memory may be a CE (Correctable Error) storm or a UCE (Uncorrectable Error) abnormality; the abnormal state of the disk may be a read-only abnormality; the abnormal state of the network card may be a serious network card error abnormality; the first abnormal state of the link may be an unexplained shutdown abnormality, and the second abnormal state of the link may be a frequent interruption abnormality. The abnormal states corresponding to the hardware include but are not limited to the above-mentioned abnormal states.

[0066] Specifically, check whether the CPU has CPU instruction anomalies, CPU stuck anomalies, etc. in turn. If so, end the detection and determine whether the node is in a suspended state. If not, continue to check whether the memory has CE storms or UCE anomalies. If so, end the detection. If not, continue to check whether the disk has read-only conditions. If so, end the detection. If not, continue to check whether the network card has serious errors. If so, end the detection. If not, continue to check whether the link is frequently interrupted or closed without reason. If so, end the detection.

[0067] In some specific implementations, if each hardware of the node is in a normal state, obtaining the node load of the node, and determining that the node is in a suspended state when detecting that the node load of the node is in an abnormal state includes:

[0068] Obtaining the current node load of the node, and determining whether the current node load is within a preset standard range;

[0069] If the current node load is outside the preset standard range, the historical node load is obtained, and it is determined whether the node load of the node is in an abnormal state based on the current node load and the historical node load.

[0070] Here, the preset standard range can be preset according to user needs.

[0071] Specifically, when there are no abnormalities in all hardware, the node load of the node is detected, the current node load and the historical node load are obtained, and it is determined whether the node load exceeds the standard range for multiple consecutive times. If so, it is determined that the node is in a suspended state.

[0072] In some specific implementations, obtaining the high-availability service corresponding to the node and disconnecting the storage service corresponding to the node through the high-availability service includes:

[0073] Performing heartbeat detection on the node through the high availability service corresponding to the node;

[0074] According to the heartbeat detection result of the node, the storage service corresponding to the node is cut off.

[0075] Here, the heartbeat detection is that end A sends a heartbeat message to end B to detect whether end A can receive the heartbeat message returned by end B within a preset time.

[0076] The node is in a system, and the system may include multiple nodes.

[0077] Furthermore, after the storage service of the pseudo-dead node is cut off, the data to be stored in the pseudo-dead node is distributed to other nodes.

[0078] Exemplarily, the heartbeat detection of a node may be to send heartbeat information to any other node for the current node to determine whether the current node can receive the heartbeat information returned by the other node within a preset time.

[0079] Specifically, a waiting time is preset, and the high availability service of the current node sends heartbeat information to other nodes. After the waiting time is reached, the high availability service checks the current node, and after detecting that the heartbeat information has not been received, the storage service of the current node is cut off.

[0080] In this way, the stability of the system can be ensured by handling the suspended nodes through high-availability services.

[0081] In some embodiments, the method further comprises:

[0082] Obtaining the network status corresponding to the node;

[0083] Determining a network delay of the node according to the network state;

[0084] According to the network delay, the hardware operating parameters of the node are modified.

[0085] In this way, the influence of the network status on the detection of the suspended state of the node can be avoided.

[0086] In one embodiment, Figure 2 Schematic diagram of the system architecture in the embodiment of the present application. Figure 2 As shown, the system architecture in the present application includes: the system includes multiple nodes, each node includes a false death detection module, a high-availability service module, and a storage service module. Specifically, the false death detection module identifies the false death node, interrupts the network port of the false death node, and performs heartbeat detection between nodes through the high-availability service corresponding to the false death node. Since the false death detection module interrupts the network port of the false death node, resulting in a heartbeat detection timeout, the high-availability service implements the operation of cutting off the storage service of the node for the node with a heartbeat detection timeout.

[0087] In one embodiment, Figure 3 FIG. 1 is a flow chart of suspended animation recognition in an embodiment of the present application, as shown in FIG. Figure 3 As shown, the process of false death identification includes: S301: capturing kernel error reports about CPU exceptions; S302: capturing kernel error reports about memory exceptions; S303: capturing kernel error reports about system disk read-only status; S304: capturing kernel error reports about network card exceptions; S305: capturing kernel error reports about link exceptions; S306: determining whether there is a read-only status or an exception error, if so, executing S308: shutting down all network cards of the node, if not, executing S307: determining whether the system load is greater than a threshold, if so, executing S308, if not, ending the process.

[0088] It should be understood that although Figure 1-3 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. Moreover, Figure 1-3 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times.
