Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
In view of the above object, a first aspect of embodiments of the present invention proposes an embodiment of a method of monitoring a timed snapshot task. Fig. 1 shows a schematic flow diagram of the method.
As shown in fig. 1, the method may include the steps of:
s1 detects a system environment every time a threshold time elapses, and determines whether or not the snapshot task is affected based on the detected system environment.
The method can adopt C language and Python language, design a monitoring module for realizing the timing snapshot task, integrate the monitoring module into the system and automatically run according to the set parameters. The method comprises the steps of performing directional detection on environmental conditions required by snapshot task triggering to prevent snapshot related operation from being failed in execution, notifying a user when an abnormal environment exists, notifying the user of a potential risk that the timing snapshot related operation fails, preprocessing by the user, and performing detection for multiple times if a certain time is left between the completion of the timing snapshot task and the next time before the timing snapshot task is triggered, for example, setting the detection to be performed once every 30 minutes, and performing the detection 2h before the next timing snapshot task is triggered, wherein the detection can be performed for 4 times at most. The method can provide a manual calling interface for a user, and after the user finishes processing, the manual calling can be used for detecting and judging whether the user operation is effective or not. A user interface may be provided to allow the user to manually turn off the automatic monitoring function and provide a list of currently monitored resources to the user for selection. The method can provide an interface for the user to open the application at fixed time, and when the user adopts a mode of temporarily closing part of the application to reduce the risk of operation failure of the snapshot task, the application can be added into the application list which is opened at fixed time, and the application is automatically opened at the appointed time. Extensible interfaces can be reserved, new resources can be actively added for monitoring according to requirements, and thresholds can be actively set. During detection, the utilization rate of a CPU of the system, the data volume of I/O waiting and the data of the capacity of the storage pool can be detected respectively every threshold time, the detected data are compared with corresponding preset thresholds respectively, and if the detected data of any one of the utilization rate of the CPU, the data volume of I/O waiting and the capacity of the storage pool is greater than the corresponding preset threshold, the influence of the system environment on the snapshot task is determined. During detection, a multi-point detection averaging strategy is adopted, a detection time period and a detection interval time are firstly set, then the utilization rate of a CPU (central processing unit) of the system, the data volume of I/O (input/output) waiting and the data of the storage pool capacity are detected once every detection interval time in the detection time period, and finally the detected data of the same type are added and averaged to obtain the final detection data.
S2 sends the detected system parameters and corresponding alerts to the user in response to the detected system environment affecting the snapshot task.
If the judgment result shows that the current system environment may affect the snapshot task to be performed, the detected specific data and the alarm need to be sent to the user, and the user is prompted to close part of the application or take other abnormal countermeasures, so as to reduce the risk of the snapshot task operation failure.
S3, in response to the trigger condition of the snapshot task being satisfied, executes the snapshot task and determines whether the snapshot task is successfully executed.
When a user creates a timing snapshot task for a file system, the system automatically allocates resources for the file system, sets the timing task, periodically polls the timing task, judges whether a triggering condition of the timing snapshot task is met, deletes or creates a snapshot after the triggering condition is met, and continuously judges whether the deletion or creation operation of the snapshot is successfully executed.
S4 re-executes the snapshot task at set intervals for a preset period of time in response to the snapshot task execution failure.
If the execution of the deleting or creating operation of the snapshot fails, the system automatically judges the reason of the operation execution failure, automatically generates alarm information, and records the alarm information in the resource attribute of the timed task, wherein the attribute information records the abnormal condition and detailed abnormal condition information of the current task. After the execution of the timing snapshot task fails, a time period may be set, for example, 5 minutes, and then the snapshot task may be triggered again at an interval of 1 minute, if the snapshot creation or deletion operation is successfully executed during this period, it is queried whether the resource contains the alarm information, and if so, the alarm information is cleared, and no feedback to the user is needed.
S5 gives a warning to the user that the snapshot task failed to execute in response to the snapshot task still failing to execute within the preset time period.
If the snapshot task still fails to be executed within the time period, an alarm needs to be sent to the user, the alarm of the snapshot creation and deletion failure is separately carried out, the creation failure and the success only affect the created alarm information and do not affect the deletion of the alarm information, and vice versa. And after the alarm information is generated, reporting the alarm information, triggering detection operation of timing snapshot alarm every 5s, automatically acquiring the alarm information, and displaying the alarm information to a user.
By the technical scheme, the user can be informed in time, the risk existing in the execution process of the current timing snapshot task can be avoided in advance, the abnormal timing snapshot task can be repaired in time, loss expansion can be avoided, and user experience is improved.
In a preferred embodiment of the present invention, detecting a system environment every time a threshold time elapses, and determining whether to affect the snapshot task based on the detected system environment includes:
detecting the utilization rate of a CPU of the system, the data volume of I/O waiting and the data of the capacity of a storage pool respectively every time a threshold value is passed;
comparing the detected data with corresponding preset thresholds respectively;
and determining that the system environment influences the snapshot task in response to the fact that the detection data of any one of the utilization rate of the CPU, the amount of the I/O waiting data and the capacity of the storage pool is larger than a corresponding preset threshold value.
In a preferred embodiment of the present invention, the data for detecting the usage rate of the CPU of the system, the amount of data waiting for I/O, and the capacity of the storage pool, respectively, every lapse of the threshold time comprises:
setting a detection time period and a detection interval time;
detecting the utilization rate of a CPU of the system, the data volume of I/O waiting and the data of the capacity of a storage pool once every detection interval in a detection time period;
and adding the detected data of the same type, and averaging to obtain final detection data. The overall environment in the current system is detected, and the use condition of a CPU in the current system, the numerical value of IO wait, the capacity of a storage pool and other factors can be detected and judged. And (3) during detection, a multi-point monitoring and averaging strategy is adopted, for example, when the CPU state is detected, the system state is continuously detected for 5min, the detection is performed once every 10s, the average value is finally obtained and used for judging the utilization rate of the CPU of the system, and other data can be detected by adopting the same method. When the abnormal state and the over high utilization rate of various types of resources in the system are found, the snapshot task operation can fail, the user is prompted to close part of the applications or take other abnormal countermeasures, so that the risk of the snapshot task operation failure is reduced.
In a preferred embodiment of the present invention, the method further comprises:
and responding to any one of three conditions of system power failure, configuration node switching and system upgrading, and cleaning various types of resource residues in the system after the snapshot task is executed. Under normal conditions, when the snapshot creation or deletion operation fails to be executed, the system can automatically clear the resources generated by the operation or influence on the system configuration, and avoid generating resource residues to influence the normal operation of other services. But when the system is powered off, the configuration node is switched or the system is upgraded, the relevant snapshot operation can not normally clear the residual resource, the resource needs to be actively cleared, when the snapshot task is triggered at regular time, the residual or abnormal configuration of each type of resource in the system is actively cleared, a snapshot relation mapping table can be automatically maintained in the system, when the snapshot is created, the new snapshot information is written into the mapping table, when the snapshot is deleted, deleting the snapshot information from the mapping table, automatically cleaning after triggering the snapshot task at regular time, checking the validity of each item in the mapping table, the invalid entries are actively cleaned, the resources required by various types of snapshots in the system are verified according to the information in the mapping table, when finding the resources of the snapshot which do not exist in the mapping table, the residual resources are automatically cleaned, and the influence of the resource residue on the normal service is avoided.
Failure in the execution of the timed snapshot task may result in failure in the backup of the user data. When the system fails and data rollback is needed, the latest snapshot information of the file system cannot be obtained in time, so that the data loss cost of the file system is increased. The technical scheme of the invention can inform the user of the risk in the current timing snapshot task execution process in time, avoid in advance, inform the user in time after the abnormality occurs, repair in time, automatically clear the resource residue and abnormal configuration information of each type in the system, avoid loss expansion and improve the user experience.
