Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of storage technology, and in particular to a hard disk detection method and device. Background Art
[0002] The hard disk will become slow due to head degradation or other mechanical or environmental problems, which will cause the hard disk input and output (IO) response time to be longer. In the storage array system, user data is stored in a series of hard disks in parallel. If a hard disk is very slow, the overall read and write operations will be slow. In serious cases, it will cause business interruption. Therefore, it is necessary to detect each disk in the storage array in real time to determine the slow disk so that the slow disk can be isolated or backed up in time.
[0003] Related technologies usually detect slow disks based on the average IO service time. For example, if the average IO service time of a disk during the detection period is greater than a preset threshold, the disk is judged as a slow disk. However, related technologies often judge normal hard disks as slow disks, with a high misjudgment rate.
[0004] Therefore, how to improve the accuracy of slow disk detection is one of the problems that technical personnel in this field need to solve urgently. Summary of the invention
[0005] The embodiment of the present application provides a hard disk detection method and device, which can improve the accuracy of slow disk detection. To achieve the above purpose, the embodiment of the present application adopts the following technical solutions:
[0006] In a first aspect, an embodiment of the present application provides a hard disk detection method, the method comprising: obtaining first information of a hard disk array. Determining a target hard disk from the hard disk array based on the first information. Isolating the target hard disk. Obtaining second information of the target server. Determining status information of the target hard disk based on the second information. The first information comprises at least one of the IO latency of the hard disks in the hard disk array, the number of IOs per second (input and output per second, IOPS) of the hard disks, and the bandwidth of the hard disks, the hard disk array is used to provide storage services for the target server, the second information comprises at least one of the IO latency, IOPS, and bandwidth, and the status information is used to indicate whether the target hard disk is a slow disk.
[0007] Related technologies usually identify slow disks based on absolute comparison (comparison with a unified threshold) or horizontal comparison (comparison between multiple disks, or comparison with a fixed threshold) of the hard disk's IO parameters. Slow disk detection based only on the hard disk's IO parameters does not take into account the actual degree of impact on the business, and the detection is not accurate enough. To this end, the method provided in the embodiment of the present application, by additionally introducing the IO parameters of the business end (i.e., the target server) during the slow disk detection process, determines the actual degree of impact of the hard disk on the business through the IO parameters of the target server. It can be seen that the method provided in the embodiment of the present application, during the slow disk detection process, not only takes into account the IO parameters of the hard disk, but also takes into account the IO parameters of the server end, thereby improving the accuracy of slow disk detection.
[0008] In a possible implementation manner, the target hard disk may be determined from the hard disk array according to the first information and the detection threshold.
[0009] It can be seen that the method provided in the embodiment of the present application can determine the target hard disk (potential slow disk) from the hard disk array through the first information characterizing the hard disk IO parameters, and then further determine whether the potential slow disk is a slow disk through the server IO parameters of the hard disk array. Due to the method provided in the embodiment of the present application, in the slow disk detection process, not only the IO parameters of the hard disk are considered, but also the IO parameters of the server are considered, thereby improving the accuracy of slow disk detection.
[0010] In a possible implementation manner, the detection threshold may be adjusted according to the above state information.
[0011] It is understandable that if the detection threshold is set too low, it may result in the inability to determine the target hard disk (potential slow disk) from the hard disk array based on the hard disk IO parameters, and if the detection threshold is set too high, a normal hard disk may be misjudged as the target hard disk (potential slow disk). To this end, the method provided in the embodiment of the present application can also adjust the dynamic detection threshold according to the above-mentioned status information. On the one hand, it can avoid the inability to determine the target hard disk (potential slow disk) from the hard disk array based on the hard disk IO parameters due to the detection threshold being set too low, and on the other hand, it can avoid the misjudgment of a normal hard disk as the target hard disk (potential slow disk) if the detection threshold is set too high.
[0012] In a possible implementation, the target hard disk may be released from isolation if the target hard disk is not a slow disk.
[0013] It is understandable that if the target hard disk (potential slow disk) is not a slow disk, it means that the target hard disk does not affect the server IO business, and the target hard disk can be released from isolation, thereby avoiding long-term isolation of the target hard disk affecting the stability of the hard disk array.
[0014] Optionally, the first information may also include link status information.
[0015] In a possible implementation manner, whether the link of the hard disk array is normal may be determined based on the link status information.
[0016] It can be seen that the method provided in the embodiment of the present application can determine the potential abnormal link from the hard disk array by characterizing the link status information of the hard disk array link, and then further determine whether the potential abnormal link is abnormal by the server IO parameters of the hard disk array. Since the method provided in the embodiment of the present application not only considers the link status but also the server IO parameters in the link detection process, the accuracy of link detection is improved.
[0017] Optionally, the first information also includes interface card status information.
[0018] In a possible implementation manner, whether the interface card of the hard disk array is normal may be determined according to the interface card status information.
[0019] It can be seen that the method provided in the embodiment of the present application can determine the potential abnormal interface card from the hard disk array by characterizing the interface card status information of the hard disk array interface card, and then further determine whether the potential abnormal interface card is abnormal by the server IO parameters of the hard disk array. Due to the method provided in the embodiment of the present application, in the interface card detection process, not only the interface card status but also the server IO parameters are considered, thereby improving the accuracy of interface card detection.
[0020] Optionally, the first information further includes garbage collection (GC) information.
[0021] In a possible implementation manner, whether the GC of the hard disk array is normal may be determined according to the GC information.
[0022] It can be seen that the method provided in the embodiment of the present application can determine the potential abnormal GC module from the hard disk array by characterizing the GC information of the hard disk array GC module, and then further determine whether the potential abnormal GC module is abnormal by the server IO parameters of the hard disk array. Since the method provided in the embodiment of the present application not only considers the GC information but also the server IO parameters in the GC detection process, the accuracy of GC detection is improved.
[0023] In a second aspect, the present application implements a hard disk detection device, which includes: a transceiver unit and a processing unit. The transceiver unit is used to obtain first information of the hard disk array, and the first information includes at least one of the IO latency of the hard disk in the hard disk array, the IOPS of the hard disk, the bandwidth of the hard disk, the average IO service time or the average response time, and the hard disk array is used to provide storage services for the target server. The processing unit is used to determine the target hard disk from the hard disk array according to the first information. The processing unit is also used to isolate the target hard disk. The transceiver unit also obtains second information of the target server, and the second information includes at least one of the IO latency, IOPS, bandwidth, average IO service time or average response time. The processing unit is also used to determine the status information of the target hard disk according to the second information, and the status information is used to indicate whether the target hard disk is a slow disk.
[0024] In a possible implementation manner, the processing unit is specifically configured to: determine a target hard disk from the hard disk array according to the first information and a detection threshold.
[0025] In a possible implementation manner, the processing unit is further configured to: adjust a detection threshold according to the status information.

[0030] In a possible implementation, the processing unit is further configured to determine whether the interface card of the hard disk array is normal according to the interface card status information.
[0031] In a possible implementation manner, the first information further includes garbage collection (GC) information.
[0032] In a possible implementation, the processing unit is further configured to determine whether the GC of the hard disk array is normal according to the GC information.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.

[0053] It should be noted that in the description of the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present application should not be interpreted as having priority or advantage over other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.
[0054] First, the terms involved in the embodiments of the present application are explained.
[0055] Slow disk: A slow disk refers to a problem with the hard disk's internal firmware (FW) or media, which increases the latency of the hard disk's external IO access, ultimately affecting the service returned by the array to the server, causing freezes or interruptions.
[0056] The hard disk will become slow due to head degradation or other mechanical or environmental problems, which will cause the hard disk input and output (IO) response time to be longer. In the storage array system, user data is stored in a series of hard disks in parallel. If a hard disk is very slow, the overall read and write operations will be slow. In serious cases, it will cause business interruption. Therefore, it is necessary to detect each disk in the storage array in real time to determine the slow disk so that the slow disk can be isolated or backed up in time.
[0057] Related technologies usually detect slow disks based on the average IO service time. For example, if the average IO service time of a disk during the detection period is greater than a preset threshold, the disk is judged as a slow disk. However, related technologies often judge normal hard disks as slow disks, with a high misjudgment rate.
[0058] To this end, an embodiment of the present application provides a hard disk detection method, which can be applied to a storage system. Figure 1 A schematic diagram of a storage system 100 provided in an embodiment of the present application is shown in FIG. Figure 1 The storage system 100 shown may include: a hard disk array 101 , a hard disk detection device 102 and a server 103 .
[0059] The hard disk array 101 is used to provide storage services for the server 103. The hard disk array 101 includes multiple storage media.
[0060] Optionally, the above storage medium includes but is not limited to a solid state drive, a mechanical hard drive, a memory or a memory disk.
[0061] The hard disk detection device 102 is used to perform slow disk detection on the hard disk array 101 .
[0062] Optionally, the hard disk detection device 102 may be integrated with the hard disk array 101 or the server 103 .
[0063] Optionally, the above schematic diagram is only an example. In actual applications, the components in the above storage system 100 may be added or deleted according to actual needs. Figure 1 It should not be understood as limiting the embodiments of the present invention.
[0064] Figure 2 A hard disk detection method provided in an embodiment of the present application is shown, and the method includes:
[0065] S201: Acquire first information of a hard disk array.
[0066] Among them, the above-mentioned first information includes at least one of the IO latency of the hard disk in the above-mentioned hard disk array, the IOPS of the above-mentioned hard disk, the bandwidth of the above-mentioned hard disk, the IO average service time or the average response time, and the above-mentioned hard disk array is used to provide storage services for the target server.
[0067] Optionally, the above-mentioned first information may also include link status information.
[0068] Optionally, the first information may also include interface card status information.
[0069] Optionally, the first information may also be GC information.
[0070] S202: Determine a target hard disk from a hard disk array according to the first information.
[0071] In a possible implementation manner, the target hard disk may be determined from the hard disk array according to the first information and the detection threshold.
[0072] The detection threshold includes multiple detection thresholds, including at least one of an IO latency detection threshold, an IOPS detection threshold, a bandwidth detection threshold, an IO average service time detection threshold, or an average response time detection threshold.
[0073] Exemplarily, when the IO latency of the hard disk is greater than the IO latency detection threshold, the hard disk can be determined as the above-mentioned target hard disk (i.e., a potential slow disk); when the IO latency of the hard disk is less than the IO latency detection threshold, the hard disk can be determined as a normal hard disk.
[0074] S203: Isolate the target hard disk.
[0075] Exemplarily, when the IO latency of a hard disk is greater than an IO latency detection threshold, the hard disk may be determined as the target hard disk and temporarily isolated.
[0076] S204: Obtain second information of the target server.
[0077] The second information includes at least one of IO latency, IOPS, bandwidth, IO average service time or average response time.
[0078] It should be noted that, unlike the first information which represents the operating status of the hard disk in the hard disk array, the second information is used to represent the operating status of the hard disk on the server side.
[0079] S205: Determine status information of the target hard disk according to the second information.
[0080] The above-mentioned status information is used to indicate whether the above-mentioned target hard disk is a slow disk.
[0081] In a possible implementation, the status information of the target hard disk can be determined based on the second information at the first moment and the second information at the second moment, where the first moment is the moment before isolating the target hard disk and the second moment is the moment after isolating the target hard disk.
[0082] Exemplarily, taking the second information including IO latency as an example, if the IO latency at the first moment (hereinafter referred to as the first IO latency) is greater than the IO latency at the second moment (hereinafter referred to as the second IO latency), it can be determined that the target hard disk is a slow disk.
[0083] It is understandable that if there is a slow disk in the hard disk array, the operating parameters of the hard disk array server will be affected by the slow disk and the performance will be reduced. After isolating the slow disk in the hard disk array, the operating parameters of the hard disk array server will be improved. The first IO delay is greater than the second IO delay, which means that after isolating the potential slow disk, the IO delay of the server is reduced and the IO performance is improved. Therefore, when the first IO delay is greater than the second IO delay, the target hard disk (potential slow disk) can be determined to be a slow disk.
[0084] In a possible implementation, the change amount can be determined based on the second information at the first moment and the second information at the second moment, and the status information of the target hard disk can be determined based on the second information at the first moment, the second information at the second moment and the change amount.
[0085] Exemplarily, taking the second information including IO latency as an example, if the first IO latency is greater than the second IO latency and the change in the first IO latency and the second IO latency (i.e., the absolute value of the difference between the first IO latency and the second IO latency) is greater than a preset change threshold, it can be determined that the target hard disk (potential slow disk) is a slow disk.
[0086] It is understandable that the operating parameters of the hard disk array server have certain fluctuations, because there is a certain probability of misjudgment when judging whether a potential slow disk is a slow disk only by the size of the operating parameters of the hard disk array server before and after the isolation of the potential slow disk. For this reason, the fluctuation of the operating parameters of the hard disk array server can be balanced by introducing a variation, thereby further reducing the probability of misjudgment of slow disk detection.
[0087] In a possible implementation manner, the detection threshold may also be adjusted according to the above state information.
[0088] For example, Figure 3 As shown in the figure, the hard disk array is tested for slow disks at time 1, but no slow disk is detected. The IO latency of the server is increasing between time 1 and time 2, indicating that there may be a slow disk in the hard disk array, which affects the service of the server. However, the current detection threshold is too slow, so the detection threshold can be increased at time 2.
[0089] After increasing the detection threshold at time 2, no slow disk is detected. However, the IO latency of the server is still increasing between time 2 and time 3, indicating that there may be a slow disk in the hard disk array, which affects the service of the server. However, the current detection threshold is too slow, so the detection threshold can be further increased at time 3.
[0090] After the detection threshold is increased at time 3, a potential slow disk (i.e., the target hard disk) is detected. After the potential hard disk is isolated, the IO latency of the server begins to decrease, and it can be determined that the potential hard disk is a slow disk.
[0091] Another example is Figure 4 As shown, at time 1, a slow disk detection is performed on the hard disk array, and a potential slow disk is detected. After the potential hard disk is isolated, the IO latency of the server does not change, indicating that the service of the server is not affected by the potential slow disk. It can be determined that the potential hard disk is a normal hard disk, and the current detection threshold is too sensitive, so the detection threshold can be reduced at time 2.
[0092] After the detection threshold is reduced at time 2, a potential slow disk is detected again. After the potential hard disk is isolated, the IO latency of the server does not change, indicating that the service of the server is not affected by the potential slow disk. It can be determined that the potential hard disk is a normal hard disk, and the current detection threshold is too sensitive. In this case, the detection threshold can be further reduced at time 3.
[0093] After reducing the detection threshold at time 3, no change in the IO latency of the slow disk server was detected, indicating that the service on the server side was not affected by the potential slow disk.
[0094] It is understandable that if the detection threshold is set too low, it may be impossible to determine the target hard disk (potential slow disk) from the hard disk array based on the hard disk IO parameters, and if the detection threshold is set too high, a normal hard disk may be misjudged as the target hard disk (potential slow disk). To this end, the method provided in the embodiment of the present application can also adjust the dynamic detection threshold according to the above-mentioned status information. On the one hand, it can avoid the detection threshold being set too low, resulting in the inability to determine the target hard disk (potential slow disk) from the hard disk array based on the hard disk IO parameters, and on the other hand, it can avoid the detection threshold being set too high, resulting in the normal hard disk being misjudged as the target hard disk (potential slow disk).
[0095] In a possible implementation, the target hard disk may be released from isolation when the target hard disk is not a slow disk.
[0096] Exemplarily, taking the case where the second information includes IO latency, if the IO latency at the first moment is smaller than the IO latency at the second moment, it can be determined that the target hard disk is a normal hard disk, and the target hard disk can be released from isolation.
[0097] In a possible implementation manner, whether the link of the hard disk array is normal may also be determined based on the link status information.
[0098] Exemplarily, the link status information of the first hard disk link in the first information can be compared with a preset link status threshold to determine whether the first hard disk link is an abnormal hard disk link. If it is determined that the first hard disk link is a potential abnormal hard disk link, the first hard disk link can be isolated, and then the second information before and after the isolation of the first hard disk link can be compared to determine whether the first hard disk link is an abnormal link. The first hard disk link is any hard disk link in the above hard disk array.
[0099] It is understandable that if there is an abnormal hard disk link in the hard disk array, the operating parameters of the hard disk array server will be affected by the abnormal hard disk link and the performance will be reduced. After isolating the abnormal hard disk link in the hard disk array, the operating parameters of the hard disk array server will be improved. Therefore, by comparing the second information before and after isolating the first hard disk link to determine whether the operating parameters of the hard disk array server are improved, it can be determined whether the first hard disk link is an abnormal hard disk link.
[0100] In a possible implementation manner, the preset link status threshold may also be adjusted according to the status information.
[0101] In a possible implementation manner, it may also be determined whether the interface card of the hard disk array is normal according to the interface card status information.
[0102] Exemplarily, the interface card status information of the first interface card in the first information can be compared with a preset interface card status threshold to determine whether the first interface card is an abnormal interface card. If it is determined that the first interface card is a potential abnormal interface card, the first interface card can be isolated, and then the second information before and after the isolation of the first interface card can be compared to determine whether the first interface card is an abnormal link. The first interface card is any interface card in the above-mentioned hard disk array.
[0103] It is understandable that if there is an abnormal interface card in the hard disk array, the operating parameters of the hard disk array server will be affected by the abnormal interface card and the performance will be reduced. After isolating the abnormal interface card in the hard disk array, the operating parameters of the hard disk array server will be improved. Therefore, by comparing the second information before and after isolating the first interface card, it can be determined whether the operating parameters of the hard disk array server are improved, thereby determining whether the first interface card is an abnormal interface card.
[0104] In a possible implementation manner, the preset interface card status threshold may also be adjusted according to the interface card status information.
[0105] In a possible implementation manner, it may also be determined whether the GC of the hard disk array is normal according to the GC information.
[0106] Exemplarily, the GC information of the first GC module in the first information can be compared with a preset CG threshold to determine whether the first GC module is an abnormal GC module. If it is determined that the first GC module is a potential abnormal GC module, the first GC module can be isolated, and then the second information before and after the isolation of the first GC module can be compared to determine whether the first GC module is an abnormal link. The first GC module is any GC module in the above-mentioned hard disk array.
[0107] It is understandable that if there is an abnormal GC module in the hard disk array, the operating parameters of the hard disk array server will be affected by the abnormal GC module and the performance will be reduced. After isolating the abnormal GC module in the hard disk array, the operating parameters of the hard disk array server will be improved. Therefore, by comparing the second information before and after isolating the first GC module, it can be determined whether the operating parameters of the hard disk array server are improved, thereby determining whether the first GC module is an abnormal GC module.
[0108] In a possible implementation, the preset CG threshold may also be adjusted according to the GC information.
[0109] In a possible implementation, whether a target device in the hard disk array is abnormal can be determined according to the first information and the second information, and the target device includes at least one of a hard disk, a hard disk link, an interface card or a GC module.
[0110] Optionally, whether multiple target devices are abnormal can be determined simultaneously based on the first information and the second information, or can be determined in sequence.
[0111] Exemplarily, it may be determined whether the hard disk is a slow disk based on the first information and the second information.
[0112] In the case that the hard disk is a slow disk, the detection of whether the remaining undetected target devices are abnormal is stopped or the detection of whether the remaining undetected target devices are abnormal is continued.
[0113] When the hard disk is normal, it is determined whether the hard disk link is faulty according to the first information and the second information.
[0114] In the case of a hard disk link abnormality, stop detecting whether the remaining undetected target devices are abnormal or continue detecting whether the remaining undetected target devices are abnormal.
[0115] When the hard disk link is normal, it is determined whether the interface card is faulty according to the first information and the second information.
[0116] In the case of an abnormality in the interface card, the detection of whether the remaining undetected target devices are abnormal is stopped or the detection of whether the remaining undetected target devices are abnormal is continued.
[0117] When the interface card is normal, it is determined whether the GC module is faulty according to the first information and the second information.
[0118] In the case of an abnormality in the GC module, the detection of whether the remaining undetected target devices are abnormal is stopped or the detection of whether the remaining undetected target devices are abnormal is continued.
[0119] When the GC module is normal, detect whether the remaining undetected target devices are abnormal.
[0120] If the above-mentioned multiple target devices are all normal, the detection thresholds of the multiple target devices can be lowered and detection can be continued, and the cycle is repeated until an abnormal target device is detected.
[0121] It is understandable that there are multiple devices in the hard disk array, and the failure of each of the multiple devices may cause the hard disk array failure (such as abnormal IO operating parameters, IO errors or IO hangs). Therefore, the multiple devices in the hard disk array can be detected simultaneously or polled according to the operating parameters of the hard disk array and the operating parameters of the hard disk array server until the abnormal device in the hard disk array is determined and processed to restore the hard disk array to normal.
[0122] In a possible implementation, when there is an IO error or IO hang in the hard disk array, it can be determined whether the target device in the hard disk array is abnormal according to the first information and the second information.
[0123] The following will be combined Figure 5 A hard disk detection device for executing the hard disk detection method is introduced.
