Description

Technical Field

[0001] The present application relates to a multi-path early warning method and system, and belongs to the technical field of multi-path early warning solutions in cloud computing storage. Background Art

[0002] Multipath storage is widely used in cloud computing storage due to its advantages, including failover and recovery, I / O load balancing, disk virtualization, and filtering of I / O suspension and transient jitter. Multipathing makes the system more robust and stable, and improves I / O bandwidth.

[0003] Currently, the most widely used open-source multipathing software in cloud computing storage is Red Hat's multipath-tools. However, multipath-tools lacks a multipathing alarm framework, including mechanisms for defining, checking, reporting, and querying multipathing-related alarms. Currently, only personnel with limited storage multipathing knowledge can manually analyze large amounts of logs and perform status queries to determine the actual health status of each multipathing object (whether it is available, whether there are potential risks, etc.), which is time-consuming and laborious. Furthermore, typical operations and maintenance personnel cannot promptly understand the actual health status of each multipathing object on the host (whether it is available, whether there are potential risks, etc.), making it difficult to obtain the actual health status of multipathing objects in a timely manner. Furthermore, even those who do have access to the actual health status can only determine the actual health status of multipathing objects through manual analysis of large amounts of logs and status queries, which is time-consuming and labor-intensive.

[0004] Therefore, in the existing technical solutions, it is time-consuming and laborious to obtain the actual health status of the multi-path objects, and it is inconvenient to obtain them in time. Summary of the Invention

[0073] The following examples are used to illustrate the present application but are not used to limit the scope of the present application.

[0074] The application of multipath objects in cloud computing storage is becoming more and more widespread. However, there are many disadvantages, such as (1) users cannot easily know whether there are multipath object failures or partial subpath failures in the system. They can only query through multipath-ll. If there are many multipath objects, it is necessary to manually determine which multipath objects have abnormal paths. If there are hundreds of multipath objects, the workload will be relatively large. The current solution does not have an active reporting mechanism, and the upper management cannot perceive it. It can only be discovered after the customer business is inaccessible and the operation and maintenance manually query. (2) When some paths in the multipath are always in a state of intermittent performance, it will not only affect the overall IO performance, but may even cause serious problems such as IO link blocking and upper-layer application jamming. Currently, there is no solution to check path status oscillation. Generally, after the business has been affected and the problem has been located, experienced operation and maintenance personnel and developers can only determine whether oscillation has occurred by querying and analyzing the multipath status and logs. Currently, there is no mechanism for automatically detecting path status oscillation and reporting. Generally, after the business has been affected and the problem has been located, operation and maintenance personnel and developers can query, analyze and determine whether path oscillation has occurred. Users cannot easily know whether there is a storage link oscillation fault. (3) Users cannot know whether there are sub-paths lost in the multipath object, and the system faces the risk of performance degradation or even business interruption. When some paths in the multipath are lost, due to the current lack of automatic checking and reporting mechanism, the upper-layer business still has available paths that are temporarily unaffected. There is no abnormality in querying the multipath status through commands, but the load balancing capability has been weakened at this time. Moreover, when the remaining available paths are abnormal, there is no path to switch to. The multipath will become unavailable and the upper-layer business will be interrupted. In fact, the previously lost paths may be good. If these paths are not lost, the failover can be performed to ensure that the customer business is not interrupted. If there is an alarm for path loss, the occurrence of these two failure situations can be avoided to a large extent; (4) Multipath does not have an alarm similar to that indicating the change of the backend block device status. The operation and maintenance personnel will not be notified in time whether there is any abnormality in the backend storage, whether the backend storage configuration has changed or the link has changed, and they will not be able to eliminate the risk in time.

[0075] To address these issues, this patent proposes a new multipath alarm management framework: it mainly introduces five types of multipath alarms and provides corresponding detection, storage, reporting, and query management mechanisms for these five types of multipath alarms. This application provides a multipath early warning technology solution that improves the maintenance and management capabilities of multipath. Based on the most widely used open source multipath software multipath-tools, it adds a multipath early warning function, which makes up for the lack of multipath early warning mechanisms in existing technical solutions in terms of definition, inspection, reporting, and query. This solves the lack of multipath's function of automatically detecting multipath anomalies and reporting alarms to the upper layer, improves the automation level of multipath maintenance, reduces the difficulty and workload of multipath maintenance, and helps enhance the stability of the system.

[0076] Example 1

[0077] The present invention provides a multi-path early warning method for warning of operation failures of multi-path objects in cloud computing storage. Figure 1 As shown, the method includes:

[0078] Step S12: upon receiving the warning information query command, obtaining parameter information in the alarm object of the multipath object corresponding to the query command in the computer storage corresponding to the multipath and the corresponding map.total_paths variable value stored in the computer storage; wherein the parameter information in the alarm object includes the alarm.map_failed value, the alarm.path_loss value, the alarm.jitter value, and the alarm.backend_change value;

[0079] In the present embodiment, after or before receiving the early warning information query command, the path status is checked by polling the check thread. If it is found that all sub-paths in the multi-path object map have failed, the map.alarm.map_failed value is set to true (1). If it is found that the status of a path in the map has changed from bad to good, the alarm.map_failed flag of the map corresponding to the path is set to 0.

[0080] When the check thread checks the status of each path in rotation and finds a path in oscillation, it sets its status to pending. It then sets the jitter flag of the alarm object in the corresponding multipath object map to 1, and logs the alarm. When the status of all subpaths improves from pending and all other subpaths are cleared, indicating that no paths are in the filtered oscillation state, the alarm is cleared and map.alarm.jitter is set to 0.

[0081] When the check_path thread rotates to check the path status, it can check one by one whether the number of all subpaths under the map to which each path belongs is less than the map.total_paths variable. If it is less than, the path is lost, and map.alarm.path_loss is set to 1, and an alarm is generated and logged. If map.alarm.path_loss is 1 and the number of all subpaths under the map is greater than the value of the map.total_paths variable, it means that a new path has been added. In this case, map.total_paths is updated to the latest value, and map.alarm.path_loss is set to 0, and the alarm is cleared and logged. If map.alarm.path_loss is 1 and the number of all subpaths under the map is equal to map.total_paths, it means that the lost path has been found or automatically restored. In this case, map.alarm.path_loss is set to 0, and the alarm is cleared and logged.

[0082] When a "path change," "path remove," or "path add" uevent device hot-add event occurs for at least one multipath object map, the alarm.backend_change flag of the corresponding map for that path is set to 1; the alarm.backend_chang_time flag of the map is set to the current time; and an alarm is generated and logged. This alarm is a reminder only and does not necessarily indicate a system failure. Alarm Clear: This alarm is a reminder message, recording the time of the most recent uevent event triggered by the backend storage status change. It does not need to be cleared.

[0083] Based on the above assignment of the parameter values of the alarm object, when an early warning information query command is received, the parameter information in the alarm object of the multipath object corresponding to the query command in the computer storage and the map.total_paths variable value corresponding to the computer storage can be obtained; wherein the parameter information in the alarm object includes the alarm.map_failed value, the alarm.path_loss value, the alarm.jitter value, and the alarm.backend_change value;

[0084] Step S14: determining the warning information corresponding to the corresponding path according to the parameter information in the alarm object and / or the corresponding map.total_paths variable value stored in the computer;

[0085] In the embodiment of the present application, after obtaining the parameter information in the alarm object of the multipath object map in the cloud computing storage, the corresponding fault can be determined based on the above-mentioned assignment principle.

[0086] Step S16: outputting the warning information corresponding to the warning information query command; the computer stores the corresponding map.total_paths variable value for determining the number of total paths.

[0087] In an embodiment of the present application, the output format of the warning information can be set according to actual needs, such as outputting the unique identifier of the target path where the fault occurs and the name of the corresponding multipath device. When there are multiple faulty multipath objects, the fault data items can be output and displayed in the form of a list.

[0088] In an embodiment of the present application, the warning information query command is the "multipathd show alarms" command, the "multipathd show alarm mapfailed" command, the "multipathd show alarm pathfailed" command, the "multipathd show alarm pathloss" command, the "multipathd show alarm pathjitter" command or the "multipathd show alarm backendchange". The above six command lines can be used to conveniently obtain whether there is a multipath abnormality. The multipathd show alarms command displays all alarm statistics on the host, and if it is normal, it displays none. Among them, the multipathd show alarm mapfailed command is used to display information about all failed multipath objects on the host, and if it is normal, it displays none. The multipathd show alarm pathloss command is used to display information about all multipath objects with path loss on the host, and if it is normal, it displays none.

[0089] The multipathd show alarm pathjitter command is used to display information about all multipath objects with link jitter on the host. If the error is normal, it displays none. The multipathd show alarm pathfailed command is used to display information about all multipath objects with path aging on the host. If the error is normal, it displays none. The multipathd showalarm backendchange command is used to display information about all multipath objects with backend storage changes on the host. If the error is normal, it displays none. The displayed multipath object information includes the unique identifier of the faulty multipath object, the list where the fault is stored, and the device corresponding to the faulty path.

[0090] In an embodiment of the present application, if the warning information query command is a "multipathd show alarms" command, then: obtaining parameter information in the alarm object of the multipath object corresponding to the query command in the multipath corresponding to the computer storage, including: obtaining the alarm.map_failed value, alarm.path_loss value, alarm.path_jitter value, alarm.path_failed value, and alarm.backend_change value of each multipath object in the computing storage;

[0091] Determining the warning information corresponding to the corresponding path according to the parameter information in the alarm object and / or the corresponding map.total_paths variable value stored in the computer includes:

[0092] If the alarm.map_failed value of any multipath object in the calculation and storage is true, the corresponding warning information is determined to be "path failure warning information", and the unique identifier of the multipath object with the alarm.map_failed value being true is stored in the mapfailed_list list; wherein, if the alarm.map_failed value corresponding to a said map is true, the corresponding warning information is determined to be "path failure warning information";

[0093] If the alarm.path_loss value of any multipath object in the calculation storage is true, the unique identifier of the multipath object whose alarm.path_loss value is true is stored in the pathloss_list list; wherein, if the alarm.path_loss value is true, the warning information corresponding to the target multipath object whose alarm.path_loss value is true is determined to be "path loss warning information";

[0094] If the alarm.path_jitter value of any multipath object in the calculation and storage is true, the unique identifier of the multipath object with the alarm.path_jitter value being true is stored in the pathjitter_list list; wherein, if the alarm.path_jitter value is true, the warning information corresponding to the target multipath object with the alarm.path_jitter value being true is determined to be "path jitter warning information";

[0095] If the alarm.path_failed value of any multipath object in the calculation storage is true, the unique identifier of the multipath object whose alarm.path_failed value is true is stored in the pathfailed_list list; wherein, if the alarm.path_failed value is true, the warning information corresponding to the target multipath object whose alarm.path_failed value is true is determined to be "path failure warning information";

[0096] If the alarm.backend_change value of any multipath object in the calculation storage is true, the unique identifier of the multipath object whose alarm.backend_change value is true is stored in the backendchange_list list; wherein, if the alarm.backend_change value is true, the warning information corresponding to the target multipath object whose alarm.backend_change value is true is determined to be "path change warning information";

[0097] The output of the warning information corresponding to the warning information query command includes:

[0098] Displays a target list of update operations within a preset time period, wherein the target list is at least one of a mapfailed_list list, a pathloss_list list, a pathjitter_list list, a pathfailed_list list, and a backendchange_list list.

[0099] In the embodiment of the present application, a corresponding output module needs to be set to output the fault multipath object map information queried when the warning information query command is the "multipathd show alarms" command. As an optional embodiment, the following command line code can be set:

If not handled in a timely manner, it may cause customer service abnormalities in the future, such as the "path loss alarm"; "normal" represents a general level: this alarm indicates that the system may have an abnormality, which may be a temporary change in the link. It is generally recoverable, but operations and maintenance personnel need to confirm whether it has been restored, such as the "path failure alarm." "info" represents a prompt level: this alarm is for informational purposes only and may not actually cause any harm. Operations and maintenance personnel can stop after confirming that there are no abnormalities in the environment.

Alarm cancellation: When it is found that the status of a path in the map has changed from bad to good, the alarm.map_failed flag of the map corresponding to the path is set to 0, and the alarm is cancelled and logged. For a single or partial path map, when the check thread checks the path status in rotation, if it is found that the path has failed, the alarm.path_failed of the map to which the path belongs is set to 1, and an alarm is generated and logged.

[0185] In the examples of this application, see Figure 6 As shown, it also includes:
