Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present application.
The core of the application is to provide a read-write link control method, a device and a medium, so as to prevent the normal operation of a cloud computing platform from being influenced by IO link faults and improve the stability of a system and the use experience of a user.
In order to improve the performance of the cloud computing platform and ensure the fluency and high availability of the cloud computing platform, a cloud computing service provider mostly chooses to store data in the cloud computing platform through a multilink storage platform, fig. 1 is a schematic diagram of a multipath storage platform, and as shown in fig. 1, a plurality of IO read-write links exist between each storage unit of the storage device and an HOST HOST, and when any IO read-write link fails, the HOST HOST can communicate with the storage unit through other IO read-write links, so that normal data reading and writing are ensured. However, even in the multilink storage platform, when there are too many communication links with faults, IO reading and writing may be affected, so that normal operation of the cloud computing platform is affected. In order to solve the technical problem, the application provides a read-write link control method, which is used for acquiring the performance information of each read-write link so as to judge whether each read-write link is in an abnormal state according to the performance information, and sending an alarm to a manager if the read-write link is in the abnormal state, so that the manager can timely find out the read-write link with a fault in a storage platform and timely process the read-write link; if the read-write links are not in an abnormal state, judging whether the read-write speed of each read-write link meets a preset condition or not; if the preset condition is not met, corresponding link information is acquired, so that an unstable link in the storage platform is found, and the unstable read-write link is processed conveniently. Therefore, according to the technical scheme provided by the application, the read-write link in an unprocessed abnormal state is determined through the performance information of the read-write link, and the read-write speed of the read-write link in the abnormal state is judged, so that the abnormal read-write link in the multipath storage platform is determined, and the management personnel can process the abnormal read-write link in time, thereby preventing the abnormal read-write link from affecting the normal work of the cloud computing platform, and improving the use experience of users.
In order to better understand the aspects of the present application, the present application will be described in further detail with reference to the accompanying drawings and detailed description.
Fig. 2 is a flowchart of a read-write link control method according to an embodiment of the present application, where the method is applied to a multi-path storage platform, as shown in fig. 2, and the method includes:
s10: acquiring performance information of each read-write link;
s11: judging whether each read-write link is in an abnormal state according to the performance information;
s12: and if the read-write link is in an abnormal state, sending an alarm to a manager.
The IO link (IEC 61131-9) is an open standard serial communication protocol that allows for bi-directional data exchange from sensors and devices that support the IO link and are connected to a host. Currently, linux multi-path storage technology is generally adopted to manage a multi-link storage system. The Linux multipath storage technology refers to multipath software used under a Linux operating system to realize multipath access to storage devices. It can make the computer system access to disk, and can obtain higher usability and stronger fault tolerance. When a storage device or path fails, it may continue to provide storage services to the system to prevent system paralysis. Linux multipath storage techniques can be obtained in various ways, such as hardware virtualization, soft binding, bit copying, etc. Hardware virtualization technology deploys multiple virtual nodes on each physical storage device, each node consisting of multiple virtual tracks, virtualizing the real physical paths to provide multi-path access. Soft bonding achieves multipath transmission by mapping the same member of one physical device onto multiple target devices to achieve high availability. Bit copying is the copying of data from one source storage device to multiple target storage devices to ensure system performance. By implementing the Linux multi-path storage technology, a storage service with high availability can be obtained. The system can identify and recover the single-path faults in the system in real time, and provides safe, reliable, efficient and highly available storage service for the system.
In specific implementation, the read-write link control process monitors the state of each read-write link according to the acquired performance information of each read-write link, so as to determine whether the read-write link is in an abnormal state. If the storage system is in an abnormal state, alarm information is sent to the manager in time, so that the manager maintains the storage system.
It will be appreciated that the processing results and detailed information of the fault may be sent to the administrator, and may be notified in a short message or mail to ensure that the fault is handled reasonably, in specific forms including, but not limited to, creating a chart or curve to assist the administrator in more intuitively observing the fault information.
It should be noted that the read-write links mentioned in the scheme of the present application include an operating read-write link in an operating state and an idle read-write link not in an operating state. All performance information of the working read-write link and the idle read-write link needs to be acquired simultaneously. Monitoring in real time through each read-write link to judge whether information of an error link exists or not so as to monitor the working read-write link; and meanwhile, the current multipath equipment state information is regularly checked to cover the monitoring range to the idle read-write link.
S13: if the read-write links are not in an abnormal state, judging whether the read-write speed of each read-write link meets a preset condition or not;
s14: if the preset condition is not met, determining the read-write link as an unstable link, and acquiring link information of the unstable link so as to process the read-write link.
In specific implementation, due to the large data volume involved in the cloud computing platform, under a large service pressure, the problem caused by fluctuation of the read-write link has a great influence on the data transmission operation. Therefore, in order to further improve the stability of the system, the real-time transmission speed of the read-write link needs to be monitored, when the transmission speed of the read-write link is too slow or the fluctuation of the read-write speed is too large, the current link is unstable, and when the service pressure is too large, the operation of the storage system may be affected due to the instability. Therefore, when an unstable read-write link is detected, link information of the unstable link needs to be acquired in time so as to process the read-write link.
It will be appreciated that the processing of the unstable read-write link may be to maintain it, or the link may be discarded directly, or discarded after maintenance, which is not limited herein. In specific implementation, when the service pressure of the system is too high (greater than the service pressure threshold), the unstable link can be maintained; when the traffic pressure is small (not greater than the traffic pressure threshold), the unstable link is discarded.
The application provides a read-write link control method, which is applied to a multipath storage platform and comprises the following steps: acquiring performance information of each read-write link so as to judge whether each read-write link is in an abnormal state according to the performance information, and sending an alarm to a manager if the read-write link is in the abnormal state, so that the manager can timely find out and timely process the read-write link with the fault in the storage platform; if the read-write links are not in an abnormal state, judging whether the read-write speed of each read-write link meets a preset condition or not; if the preset condition is not met, corresponding link information is acquired, so that an unstable link in the storage platform is found, and the unstable read-write link is processed conveniently. Therefore, according to the technical scheme provided by the application, the read-write link in an unprocessed abnormal state is determined through the performance information of the read-write link, and the read-write speed of the read-write link in the abnormal state is judged, so that the abnormal read-write link in the multipath storage platform is determined, and the management personnel can process the abnormal read-write link in time, thereby preventing the abnormal read-write link from affecting the normal work of the cloud computing platform, and improving the use experience of users.
As an embodiment in some embodiments, obtaining performance information of each read-write link includes: acquiring log information of each read-write link in a working state and state information of all read-write links; and determining the performance information of each link according to the state information and the log information.
In specific implementation, real-time monitoring is carried out on a plurality of multi-path read-write links to obtain corresponding multi-path read-write link real-time information; judging whether the real-time information of the multi-path read-write link contains information for indicating error events of the multi-path read-write link; meanwhile, the current multipath equipment state information is periodically checked, the length of the checking period can be set by operation and maintenance personnel, and can also be set according to the service pressure, and the checking period is not limited herein.
The data volume related to the cloud computing platform is large, and under the condition of large service pressure, the problem caused by fluctuation of a read-write link has great influence on data transmission operation. Therefore, in order to further improve the stability of the system, the real-time transmission speed of the read-write link needs to be monitored.
In a specific implementation, determining whether the read-write speed of each read-write link meets a preset condition includes: judging whether the read-write speed of the read-write link is greater than a read-write speed threshold; if the read-write speed fluctuation is larger than the read-write speed threshold, judging whether the read-write speed fluctuation of the read-write link is larger than the fluctuation threshold; if the read-write link is larger than the fluctuation threshold, determining that the read-write link does not meet the preset condition.
Detecting whether fluctuation exists in the reading and writing process of a reading and writing link in real time, defining a fluctuation threshold A, defining fluctuation interval time T1, defining a time period T2 for detecting the fluctuation, and marking the link as a sub-health state if the reading and writing speed of any reading and writing link of the multi-path equipment has fluctuation with a value larger than the fluctuation threshold A within the interval time T1 range, so that the subsequent processing is facilitated.
When the traffic pressure is small, the read-write link in the sub-health state can be degraded and prevented from being in the alternative link so as to reduce the use rate of the unstable link. If the unstable link does not fluctuate again in the verification period T2, the unstable link is recovered to a 'healthy' state, and the read-write operation of the link is recovered. It should be noted that, when judging whether the read-write link in the "sub-health" state is in the "health" state, test data may be selected, or real service data may be adopted, which will not be described herein. However, it should be noted that the real service data of the read-write link in the "sub-health" state for testing should be the data backed up in advance, so as to ensure the security of the data. In addition, after determining the link as a sub-health state, if idle read-write links exist in the system, a corresponding number of idle read-write links need to be started so as to improve the use experience of the user.
When the service pressure of the storage system is high (for example, when all read-write links are in working state), only the abnormal links are marked, and the actual working state of the links is not changed, so that the reduction of the read-write links can be prevented, and the reduction of the data read-write efficiency can be prevented.
In implementations, sending the alert to the manager includes: the abnormal state information is written into the log file, and an alarm is sent to the manager in an email mode. The management personnel can check the working condition of the link in the storage system according to the log file, so that corresponding measures are taken to ensure the normal operation of the storage system.
It can be understood that, to prevent occurrence of data loss, the method further includes, after obtaining link information of the unstable link: the signal transmission level of the unstable link is reduced to reduce the usage of the unstable link.
Correspondingly, after the step of reducing the signal transmission level of the unstable link, the method further comprises the following steps: judging whether the fluctuation of the read-write speed of the unstable link in the detection period is larger than a fluctuation threshold value or not; and if the signal transmission level is not greater than the fluctuation threshold value, restoring the signal transmission level of the unstable link.
In one embodiment, after detecting a failed read-write link, an alert is sent to the administrator and self-repair should be attempted to ensure proper operation of the system as much as possible. In a specific implementation, after the step of sending the alarm to the manager, the method further includes: acquiring fault information of a read-write link in an abnormal state, and determining a fault reason according to the fault information; and repairing the read-write link or updating the drive according to the fault reason.
Specifically, the self-repair process includes: collecting fault information of a multi-path storage system; and analyzing the position and the reason of the fault according to the fault information, and carrying out path repair or reset driving aiming at different reasons of the fault. It should be noted that, when the multi-path storage fails in the read/write data, the failure information may be collected by using, but not limited to, a hook function installed in the multi-path storage drive.
In a specific implementation, since the location of collecting the fault information is in the kernel, and the subsequent processing occurs in the user mode, PCIE fault information needs to be transmitted from the kernel to the user mode, and a specific transmission manner includes, but is not limited to, using a Netlink channel.
Specifically, according to a rule base of 'a fault or a processing mode corresponding to some faults', if a path fault is reported by a multipath, a program can correspondingly recover or isolate the path, and the position and the reason of the multipath storage fault can be classified and counted to obtain an analysis result.
It should be noted that, in the case of repairable paths, the paths with faults are repaired, and in some cases, the paths cannot be repaired, so that the problems can be solved by adopting a reset driving mode, and the reliable and stable operation of multi-path storage is ensured. The number of read-write links in a normal working state is increased, high availability and smoothness of the storage system are guaranteed, and the use experience of a user is improved.
In the above embodiments, the read-write link control method is described in detail, and the present application further provides a corresponding embodiment of the read-write link control device. It should be noted that the present application describes an embodiment of the device portion from two angles, one based on the angle of the functional module and the other based on the angle of the hardware.

and the determining module 14 is configured to determine that the read-write link is an unstable link if the preset condition is not satisfied, and acquire link information of the unstable link, so as to process the read-write link.
In addition, the read-write link control device provided by the embodiment of the application further comprises a signal transmission level reducing module, a recovery module and a maintenance module.
