Description
Technical Field
The invention relates to a signal detection technology, in particular to a heartbeat detection method and heartbeat detection equipment.
Background
At present, in order to ensure service continuity, a standby device is usually configured for a key device for processing a service, and the key device is called an active device. The standby equipment detects whether the main equipment fails by sending heartbeat messages to the main equipment and receiving heartbeat responses returned by the main equipment, and takes over the service of the main equipment when the main equipment fails, so that the service continuity is ensured.
The design ideas of the main equipment and the standby equipment are widely applied to a plurality of network systems. Taking a network storage system as an example, fig. 1 is a schematic diagram of a networking structure of a network storage system in the prior art. As shown in FIG. 1, a network storage system includes a storage controller and a storage array. When accessing the storage system, the client establishes connection with the storage controller, so that the storage resources in the storage array are accessed through the storage controller. It can be seen that the storage controller is a key device for implementing network storage. In the network storage system shown in fig. 1, a storage controller a and a storage controller B that are active and standby with each other are provided, and the two storage controllers can provide a storage service processing service for a client at the same time.
And the storage controller A and the storage controller B judge whether the other side fails or not by interacting heartbeat messages, and if so, the other side is restarted. Specifically, the storage controller a and the storage controller B are respectively provided with a network port for heartbeat detection, which is called a heartbeat detection network port. Each storage controller is used as a home terminal to periodically send heartbeat messages to an opposite terminal through a heartbeat detection network port, and if a heartbeat response of the opposite terminal is received before the heartbeat timeout time is reached, the opposite terminal is judged to be normal; otherwise, judging that the opposite end is abnormal. And when the opposite terminal is judged to be abnormal, taking over the opposite terminal service, and then restarting the opposite terminal.
However, in practice, a situation may occur that the opposite end is normal in service processing function, and only when a transmission link between the local end heartbeat network port and the opposite end heartbeat network port fails, or the local end and/or the opposite end heartbeat network port fails, or the opposite end is busy and has no time to process heartbeat messages, the local end may not receive heartbeat responses, thereby erroneously determining that the opposite end is abnormal, and restarting the opposite end. And restarting the operation of the opposite end can cause service interruption of the opposite end.
Therefore, the existing heartbeat detection scheme cannot accurately judge the state of the opposite terminal, and when the judgment is wrong, the opposite terminal is restarted under the non-abnormal condition, so that the service interruption under the non-abnormal condition of the opposite terminal is caused.

Detailed Description
The invention is a heartbeat detecting scheme, which is applied to network equipment with a service network port, and the basic idea is as follows: the network equipment periodically sends heartbeat messages to the detection opposite terminal through the heartbeat detection port and receives heartbeat responses returned by the detection opposite terminal; when the heartbeat detection port does not receive the heartbeat response of the detection opposite end, selecting a service network port without service at present, and sending heartbeat messages to the detection opposite end through the selected service network port; judging whether the service network port receives a heartbeat response of the opposite end; if so, determining that the opposite end is detected to be normal; otherwise, determining to detect the anomaly of the opposite terminal. Under the condition of detecting the anomaly of the opposite terminal, the method can take over the service of the opposite terminal and restart the opposite terminal detection.
It can be seen that the heartbeat detection scheme of the present invention sets multiple detections, and when the heartbeat detection port cannot receive the heartbeat response, the abnormality of the opposite end is not immediately determined, but the detection is continued through the service network port. Moreover, the adopted service network port is a service network port without service, even if all the service network ports have service, the service of a selected service network port can be migrated to other service network ports, and the selected service network port is specially used for heartbeat detection, so that heartbeat messages and/or heartbeat responses can be ensured not to be discarded because the service network port is busy, the success rate of successfully receiving heartbeat responses is improved, the accuracy of judging the state of the opposite end is improved, and the probability of the opposite end being interrupted under the condition of non-abnormity due to misjudgment is further reduced.
Preferably, the heartbeat detection port includes a heartbeat detection network port and a serial port which are provided in the embodiment of the present invention and are specially used for heartbeat detection, and meanwhile, a heartbeat message is sent to the detection opposite terminal through the heartbeat detection network port and the serial port; when the heartbeat detection network port does not receive the heartbeat response of the opposite detection end, judging whether the heartbeat detection of the serial port is normal or not; and only when the heartbeat detection network port and the serial port do not receive the heartbeat response of the opposite end, determining to detect the abnormality of the opposite end. Therefore, the state of the opposite terminal can be rapidly judged from the detection condition of the serial port under the condition that the heartbeat detection network port is abnormal. Compared with the implementation mode of firstly detecting the network port by using heartbeat and then detecting the abnormal network port by using the serial port, the method has the advantages that the unnecessary waiting time during the switching of the two ports can be reduced by simultaneously detecting the serial port and the network port, and the effect of quickly judging is achieved.
The technical scheme of the invention can be suitable for heartbeat detection between the main equipment and the standby equipment. In the following description of the technical solution of the present invention, a heartbeat detection scheme of the present invention is applied to the network storage system shown in fig. 1 as an example, and the dual storage controllers in the network storage system are mutually active and standby.
The invention is described in detail below by way of example with reference to the accompanying drawings.
Fig. 2 is a flowchart illustrating a method for detecting a heartbeat of a storage controller a to a storage controller B according to an embodiment of the present invention. The principle of the method for the memory controller B to detect the heartbeat of the memory controller A is the same. As shown in fig. 2, the process includes the following steps:
step 201: the storage controller A monitors whether a service exists in the storage controller A in real time and records a service monitoring result.
In the step, whether a data service exists in a fixed time period is judged, if yes, the service exists, and if not, the service does not exist. Wherein the fixed time period may be one heartbeat cycle. The heartbeat cycle refers to a time interval between two consecutive heartbeat messages.
This step is performed continuously in a loop.
Step 202: and taking the heartbeat period as a circulation unit, and periodically sending heartbeat messages to the storage controller B through the heartbeat detection network port and the serial port at the same time.
The difference between this embodiment and the prior art is not only that the heartbeat message is sent through the heartbeat detection network port and the serial port at the same time, but also that the heartbeat message sent by this embodiment is sent in a cycle unit of heartbeat period, which is unrelated to the time of receiving the heartbeat response. Therefore, it is not necessary to wait for one heartbeat cycle to send the next heartbeat message after receiving the heartbeat response as in the prior art. Since the embodiment needs to judge the timeout of the heartbeat detection portal for multiple times to judge the anomaly of the heartbeat detection portal, the design can shorten the judgment time.
Step 203: after the heartbeat message is sent every time, judging whether the heartbeat detection gateway receives a heartbeat response fed back by the storage controller B within the current heartbeat timeout time by adopting the preset heartbeat timeout time as the current heartbeat timeout time; if yes, continuing to execute the judgment of the step 203 after next heartbeat message is sent; otherwise, step 204 is performed.
When heartbeat detection is carried out through the heartbeat detection network port, whether a serial port receives heartbeat response within the current heartbeat timeout time is synchronously judged, if yes, the serial port is determined to be normal in detection, and the serial port detection state is recorded, otherwise, the serial port is determined to be abnormal, and the serial port detection state is recorded. The recorded serial port detection state is used as the judgment basis in step 207.
Step 204: judging the heartbeat timeout, and accumulating the continuous heartbeat timeout times; and selecting the custom heartbeat timeout time different from the current heartbeat timeout time as the current heartbeat timeout time for next heartbeat timeout judgment.
And clearing the accumulated continuous heartbeat overtime frequency after the heartbeat detection network interface receives a heartbeat response.
In this step, there may be multiple ways to select a custom heartbeat timeout time different from the current heartbeat timeout time, and this embodiment introduces two preferred selection ways:
the first mode is a random mode. And randomly selecting the custom heartbeat timeout time within a preset range. For example, the custom heartbeat timeout time is: the base value plus a random value between 0 seconds(s) and 2s, the random value having a particle size of 0.1 s. If the basic value is 1.5s, the preset range of the randomly selected custom heartbeat timeout time is 1.5s-3.5 s.
The probability that the storage controllers which back up each other restart the opposite terminal at the same time can be reduced by adopting a random mode, because: in this embodiment, the storage controllers that are backed up with each other are physically disposed in the same hardware frame, so that the opposite end can be restarted through hardware. When the heartbeat path (including the path to which the heartbeat detection network port, the serial port, and the service network port are connected) between the storage controller a and the storage controller B fails, and the heartbeat response of the opposite end cannot be detected, both the storage controller a and the storage controller B may determine that the opposite end is abnormal at the same time in the process step 210, and then restart the opposite end. However, the memory controller a and the memory controller B may both be processing the traffic normally, belonging to the restart under non-exception, and then the traffic of both the memory controller a and the memory controller B is interrupted. In order to reduce the occurrence probability of such a situation as much as possible, in the embodiment, the self-defined heartbeat timeout time is determined in a random manner, so that the times of determining that the opposite terminal is abnormal are different due to different self-defined heartbeat timeout times selected by the storage controller a and the storage controller B, and the probability of restarting the opposite terminal at the same time is greatly reduced. If the range span of the custom heartbeat timeout time is randomly selected to be 2s, the random granularity is 0.1s, and 3 heartbeat timeouts are set to be considered as abnormal heartbeats, the probability that the storage controller a and the storage controller B restart the opposite end at the same time is reduced to 1/400.
In this embodiment, when it is determined that the heartbeat of the heartbeat detection portal is overtime for the first time, the user-defined heartbeat overtime time is randomly selected, in practice, preset heartbeat overtime time can be adopted when it is determined whether the heartbeat is overtime for the first m-1 times, and random selection is performed when it is determined that m-1 times of heartbeat overtime continuously occur, so that the overtime time used in the last determination is guaranteed to be a random value, and the purpose of reducing the probability of restarting the opposite end at the same time can also be achieved. Wherein m is a threshold value of the timeout times. However, the probability of restarting the opposite end at the same time can be further reduced by adopting the random value for multiple times.
The second mode and the backoff mode. And increasing the heartbeat timeout time in an increasing mode on the basis of the current heartbeat timeout time, and taking the increased heartbeat timeout time as the user-defined heartbeat timeout time. For example, the calculation formula for setting the custom heartbeat timeout time is as follows: and after the nth heartbeat is overtime, the custom heartbeat overtime time is preset heartbeat overtime time + n + n 0.1, wherein n is a positive integer, and 0.1 is an adjusting factor. If the preset heartbeat timeout time is 1.5 seconds(s), after the first heartbeat timeout occurs, the self-defined heartbeat timeout time is 1.5+1+0.1 which is 2.6 s; after the second heartbeat timeout occurs, the custom heartbeat timeout time is 1.5+2+2 × 2 × 0.1 — 3.9 s.
By adopting the back-off mode, the heartbeat timeout time can be gradually increased step by step after the heartbeat response of the opposite terminal is not received for the first time, so that the defect caused by the fact that the heartbeat response cannot be received due to too short heartbeat timeout time is avoided. If the storage controller A and the storage controller B adopt different adjustment factors, the self-defined heartbeat timeout time selected by the storage controller A and the self-defined heartbeat timeout time selected by the storage controller B are different, and the probability of restarting the opposite terminal simultaneously can be reduced like a random mode. The selection of different adjustment factors is actually setting different granularity of increments for different storage controllers, and in practice, the granularity of increments may also be randomly selected.
Step 205: judging whether the accumulated continuous heartbeat timeout times are larger than or equal to a preset time threshold value or not; if yes, go to step 207; otherwise, step 206 is performed.
For example, the preset number threshold may be set to 2 or 3.
Step 206: after the heartbeat message is sent, judging whether a heartbeat response is received within the current timeout time; if yes, go to step 203; otherwise, step 204 is performed.
Step 207: judging whether the serial port detection is normal or not; if yes, go to step 211; otherwise, step 208 is performed.
The basis for judging whether the serial port detection is normal is as follows: and step 203, recording the serial port detection state.
Step 208: and selecting a service network port without service currently, and sending heartbeat messages to the storage controller B through the selected service network port.
In this step, judging whether a service network port in a non-service state exists, if so, selecting one service network port from the service network ports in the non-service state as a selected service network port; otherwise, the preselected service network port is used as the selected service network port, and the service of the selected service network port is suspended. Before suspending the service of the selected service network port, the IP address of the service port to be suspended is configured to other service network ports, so that the service of the suspended service network port is migrated to other service network ports, and the continuity of the service is ensured.
And when the heartbeat message is sent to the storage controller B through the selected service network port, sending the heartbeat message to the storage controller B by adopting a pre-configured IP address which is in the same network segment with the service network port of the storage controller B.
Step 209: judging whether the service network port receives the heartbeat response of the storage controller B, if so, executing the step 212; otherwise, step 210 is performed.
Step 210: and determining that the storage controller B is abnormal, and restarting the storage controller B according to the service monitoring result in the step 201. The process is ended.
In this step, restarting the storage controller B according to the service monitoring result of step 201 includes:
judging whether a service exists at present according to the service monitoring result in the step 201, if so, restarting the storage controller B, and taking over the service of the storage controller B; otherwise, after waiting for a period of time, restarting the storage controller B and taking over the service of the storage controller B. The waiting time may be set in advance, for example, to 3.5 s.
In the embodiment, under the condition that the self has the service, the opposite terminal is restarted under the assumption that the opposite terminal has no service; and under the condition that the opposite terminal has no service, the opposite terminal is supposed to have no service, the opposite terminal is waited to restart the opposite terminal, the opposite terminal does not restart the opposite terminal, and then the opposite terminal is restarted. The purpose of this is to further reduce the probability that detecting both parties restarting the opposite end at the same time causes the service of both parties to be interrupted.
In the operations of restarting the memory controller B and taking over the service of the memory controller B, the embodiment first restarts the memory controller B and then takes over the service of the memory controller B, and the interval time between the two operations may be short. Since the takeover service is after restarting the opposite end, when both sides determine to restart the opposite end at the same time, such a situation can be avoided: both parties contend for taking over the confusion caused by the resources of the opposite terminal before restarting the opposite terminal.
Step 211: and alarming and detecting the heartbeat through the serial port in the subsequent heartbeat detection.
The purpose of the alarm is to inform the administrator to check the heartbeat detection portal in order to remove the failure of the heartbeat detection portal. And recovering the detection of the heartbeat detection network port after the fault is relieved.
In the subsequent process of detecting the heartbeat through the serial port, trying to perform heartbeat detection through the heartbeat detection network port, and if a heartbeat response is received through the heartbeat detection network port, returning to execute step 203 as shown by a dotted line in fig. 2.
Step 212: and alarming and detecting the heartbeat through the service network port in the subsequent heartbeat detection.
The purpose of warning is to inform the administrator to check the heartbeat detection network port and the serial port so as to relieve the failure of the heartbeat detection network port and the failure of the serial port. And recovering the detection of the heartbeat detection network port and the serial port after the failure is relieved.
In the subsequent process of detecting the heartbeat through the service network port, trying to perform heartbeat detection through the heartbeat detection network port, and if a heartbeat response is received through the heartbeat detection network port, returning to execute step 203 as shown by a dotted line in fig. 2.
This flow ends by this point.
In order to implement the heartbeat detection method of the present invention, an embodiment of the present invention further provides a heartbeat detection device. The heartbeat detection device may be applied in memory controller a and memory controller B of fig. 1.
Fig. 3 is a schematic structural diagram of a heartbeat detection device in an embodiment of the present invention.
