Background
In the field of data Storage, the main functions of an OSD (Object-based Storage Device) are to store data, copy data, balance data, restore data, and the like. In an actual use scenario, one hard disk generally corresponds to one OSD, and the OSD manages the hard disk storage. When the hard disk mounted by the OSD fails, data of the OSD needs to be recovered, and a process of recovering the data in the failed OSD from other OSDs is called data reconstruction. In addition, when the distributed file system is expanded, the OSD performs data balance, and a part of data is migrated to the OSD of the new expansion node, which is also called data reconstruction.
In the prior art, when data reconstruction occurs, a client performs read-write operation on a cluster and performs data reconstruction at the same time, and the target speed of data reconstruction of the cluster can be adjusted in order to reduce the influence of the data reconstruction on the read-write performance of the client. That is, the operation target of the data reconstruction operation is readjusted according to different feedback situations. However, at present, the purpose of adjusting the data reconstruction speed can only be achieved by manually adjusting the data reconstruction priority of the cluster, and there are four priorities of low priority, medium priority, high priority and full priority.

Detailed Description
The core of the application is to provide a data reconstruction method, a data reconstruction device, a storage server and a computer readable storage medium, the data reconstruction operation is controlled through the control target corresponding relation registered in the data reconstruction control thread, automatic adjustment according to feedback is realized, and the flexibility degree and the use experience of functions are improved.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the prior art, when data reconstruction occurs, a client performs read-write operation on a cluster and performs data reconstruction at the same time, and the target speed of data reconstruction of the cluster can be adjusted in order to reduce the influence of the data reconstruction on the read-write performance of the client. That is, the operation target of the data reconstruction operation is readjusted according to different feedback situations. However, at present, the purpose of adjusting the data reconstruction speed can only be achieved by manually adjusting the data reconstruction priority of the cluster, and there are four priorities of low priority, medium priority, high priority and full priority. The four priorities correspond to four data reconstruction speeds of low speed, medium speed, high speed and full speed. It can be seen that, in the existing scheme, the reconstruction speed is basically constant and continuous after the reconstruction priority is set, and if the reconstruction speed is adjusted, the reconstruction priority needs to be manually adjusted. The method for adjusting the target is not flexible enough, and can not meet the requirement of a user on data reconstruction control under specific conditions.
Therefore, the present application provides a data reconstruction method, by first registering a control target correspondence in a data reconstruction control thread, then controlling the reconstruction control thread to continuously and circularly execute a feedback query instruction according to a preset time period, then obtaining a feedback query result, matching a feedback threshold value in the corresponding relation of the control target, and when the matching is passed, target adjustment is carried out on the data reconstruction operation according to the control target in the registered control target corresponding relation to obtain the data reconstruction operation after the target adjustment, and finally the data reconstruction operation is executed, so that the feedback query result according to the active query is realized, rather than manually adjusting the target in the prior art, the method improves the flexibility degree in the data reconstruction process, therefore, different characteristic requirements are met under different conditions, and the use experience of using data reconstruction is improved.
Referring to fig. 1, fig. 1 is a flowchart of a data reconstruction method according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s101, registering the acquired control target corresponding relation in a data reconstruction control thread;
this step is intended to register the acquired control target correspondence in the data reconstruction control thread. The control target corresponding relation refers to a corresponding relation between a feedback source, a feedback threshold and a control target. The feedback source refers to where the feedback information is obtained, and specifically, may include a feedback query instruction. In a specific using process, a corresponding feedback query result can be obtained by directly executing the feedback query instruction. The feedback threshold refers to different operation means corresponding to different sizes of the feedback query result, and different control targets correspond to different threshold ranges. The control target refers to a target for adjusting the data reconstruction operation.
Taking the example of adjusting the reconstruction speed according to time, the control target corresponding relationship is a corresponding relationship between time and the reconstruction execution speed. Specifically, the feedback source acquires the current time, so that the corresponding feedback query instruction is the current time query instruction, and the acquired feedback query result is the current time. The feedback thresholds are different time periods, each time period corresponding to a different speed of the reconstruction operation. For example, the reconstruction speed between 0 and 5 points in time is high, and the reconstruction speed between 20 and 24 points is low.
Further, registering the control target correspondence in the data reconstruction control thread means that the control target correspondence is stored in the data reconstruction control thread. And enabling the data reconstruction control thread to execute corresponding control operation according to the registered corresponding relation. And moreover, a plurality of different control target corresponding relations can be registered in the data reconstruction control thread, corresponding priorities are set, and when the conditions of simultaneous judgment occur, the control target corresponding relation with the highest priority is selected and executed.
S102, the control data reconstruction control thread executes a feedback query instruction in the corresponding relation of the control target according to a preset time period to obtain a feedback query result;
on the basis of S101, this step aims to control the data reconstruction control thread to execute the feedback query instruction in the registered control target correspondence, and obtain a feedback query result. Generally, a corresponding feedback query instruction may be registered in the control target correspondence, and the data reconstruction control thread may directly execute the feedback query instruction to obtain the corresponding feedback query instruction. Or inquiring a corresponding feedback inquiry instruction according to a feedback source in the corresponding relation of the control target, and executing the feedback inquiry instruction to obtain a feedback inquiry result.
S103, matching the feedback query result with a feedback threshold value in the corresponding relation of the control target;
and matching the feedback query result with the feedback threshold value on the basis of the S102. The obtained feedback query result is matched with the feedback threshold value. Specifically, when the feedback query result is numerical data, the size of the feedback query result can be directly compared to obtain a corresponding control target. And when the feedback query result is other text information, directly performing matching operation to obtain a corresponding control target.
And S104, when the matching is passed, performing target adjustment on the data reconstruction operation according to the control target in the control target corresponding relation, and executing the data reconstruction operation.
On the basis of S103, this step aims to perform target adjustment on the data reconstruction operation by using the corresponding control target when the matching passes, obtain an adjusted data reconstruction operation, and execute the data reconstruction operation. Therefore, the data reconstruction operation is adjusted according to the corresponding relation of the control target instead of manual adjustment, and the adjustment flexibility is improved.
S105, when the matching is not passed, adjusting the execution target of the data reconstruction operation to be a default target, and executing the data reconstruction operation.
It can be seen that this step is intended to perform this data reconstruction operation directly with the default target when the match fails, i.e. the corresponding control target is not matched.
In addition, the present embodiment may further include:
when the feedback threshold values are matched with the multiple feedback threshold values, obtaining a control target corresponding to the feedback threshold value with the highest priority;
and performing target adjustment on the data reconstruction operation by adopting the control target, and executing the data reconstruction operation.
Therefore, when a plurality of control targets are matched, the final control target is determined according to the priority corresponding to the control target, namely, the control target with the highest priority is selected for target adjustment.
Optionally, this embodiment may further include:
and when the matching is passed, performing log recording operation to obtain log data.
In summary, in the embodiment, by first registering the control target correspondence relation in the data reconstruction control thread, then controlling the reconstruction control thread to continuously and circularly execute a feedback query instruction according to a preset time period, then obtaining a feedback query result, matching a feedback threshold value in the corresponding relation of the control target, and when the matching is passed, target adjustment is carried out on the data reconstruction operation according to the control target in the registered control target corresponding relation to obtain the data reconstruction operation after the target adjustment, and finally the data reconstruction operation is executed, so that the feedback query result according to the active query is realized, rather than manually adjusting the target in the prior art, the method improves the flexibility degree in the data reconstruction process, therefore, different characteristic requirements are met under different conditions, and the use experience of using data reconstruction is improved.
A data reconstruction method provided in the present application is further described below with reference to another specific embodiment.
In this embodiment, the method may include:
s201, registering the acquired control target corresponding relation in a data reconstruction control thread;
s202, when the corresponding relation of the control target is the corresponding relation of time and reconstruction speed, controlling a data reconstruction control thread to execute a time query instruction in the corresponding relation of the control target according to a preset time period to obtain current time;
s203, taking the current time as a feedback query result;
s204, matching the current time in the feedback query result with a time threshold value in the corresponding relation of the control target;
and S205, when the matching is passed, carrying out target speed adjustment on the data reconstruction operation according to the target execution speed in the control target corresponding relation, and executing the data reconstruction operation.
S206, when the matching is not passed, adjusting the execution target of the data reconstruction operation to be a default target, and executing the data reconstruction operation.
Specifically, the correspondence relationship is registered in the data reconstruction control thread. First, a control thread with a custom strategy is started. Then, registering the self-defined strategy, namely registering the corresponding relation of the control target.
Wherein, the process of registering mainly includes: query command, conditions triggered by the user-defined strategy and control command.
For example, if the data reconstruction of a control cluster between 1 a morning and 5 a morning is to be customized to be performed at a high speed, a command for inquiring time needs to be registered first, then a trigger condition for registering is that the time is more than 1 and less than 5, and finally a control command for modifying the data reconstruction priority is registered. Thus, the data reconstruction priority is adjusted to be high when the condition between 1 point in the morning and 5 points in the morning is met.
For another example, if the user wants to customize, when the cluster read-write service is busy, for example, when the IOPS of the read-write exceeds 5000, the data reconstruction priority needs to be adjusted to be a low priority. At this time, a command for querying the cluster IOPS needs to be registered first, then the registration triggering condition is that the value of the IOPS is greater than 5000, and finally a control command for modifying the reconstruction priority is registered.
And the control thread of the custom strategy circularly traverses the custom strategy, checks whether the triggering conditions of the custom strategy are met one by one, executes the registered control command and records the control command executed this time if the triggering conditions are met, and records the control command which does not meet the triggering conditions if the triggering conditions are not met.
In addition, after the traversal is finished, the traversal result is checked, namely the recorded result is checked. And checking the control command which does not meet the triggering condition, and modifying the parameter controlled by the command to be the default parameter if the control command is not executed in the traversal. For example, two custom policies are registered: the data reconstruction priority between 1 point in the morning and 5 points in the morning is modified into a high priority; the reconstruction priority of the data between 18 and 22 points is modified to be low priority. Then if the current time is 20 points, one of the trigger conditions is met and the reconstruction priority is modified to a high priority. If the current time is 22:30, neither trigger condition is satisfied, and the reconstruction priority needs to be modified to the reconstruction priority of the default setting of the cluster, such as the middle priority of the default setting, and then the reconstruction priority is modified to the middle priority.
As can be seen, in the present embodiment, by first registering the control target correspondence in the data reconstruction control thread, then controlling the reconstruction control thread to continuously and circularly execute a feedback query instruction according to a preset time period, then obtaining a feedback query result, matching a feedback threshold value in the corresponding relation of the control target, and when the matching is passed, target adjustment is carried out on the data reconstruction operation according to the control target in the registered control target corresponding relation to obtain the data reconstruction operation after the target adjustment, and finally the data reconstruction operation is executed, so that the feedback query result according to the active query is realized, rather than manually adjusting the target in the prior art, the method improves the flexibility degree in the data reconstruction process, therefore, different characteristic requirements are met under different conditions, and the use experience of using data reconstruction is improved.
