All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a control method, a device and a medium for information consistency of a virtualization platform, after a computing node runs a task to be executed created by a management node, whether actual information of a bottom layer virtual machine is consistent with information of a virtual machine in a database managed by the management node is compared, if the actual information of the bottom layer virtual machine is not consistent with the information of the virtual machine in the database, information synchronization operation is performed on the information of the virtual machine in the database by taking the actual information of the bottom layer virtual machine as a reference, so that the consistency of information of upper and lower layers of the virtualization platform is ensured, and the stability of the virtual machine is improved.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
The virtualization platform mainly provides virtualization services, performs resource management and the like on a computer, and is based on the virtual machine, the virtualization platform can realize the operations of migration, snapshot, backup and the like on the virtual machine, and the operations all need to depend on a management node and a computing node of the virtualization platform, the management node creates tasks of migration, backup and the like, sends the tasks to a bottom computing node, then the computing node completes the tasks, and reports an execution result to the management node.
When the virtual machine is operated, if the communication between the management node and the bottom computing node is abnormal or packet loss occurs during data transmission, the operation accuracy on the computing node cannot be guaranteed, and thus the state of the virtual machine and the information such as data are inconsistent, that is, the information of the virtual machine in the database managed by the management node is inconsistent with the information of the virtual machine after the computing node completes the task operation. At this time, if the virtual machine is restarted, the disk of the virtual machine is switched to a state before the exception occurs, so that the data of the virtual machine in the running process is lost.
In order to solve the problem that information of a management node and a computing node is inconsistent due to communication abnormality, packet loss and the like, reduce the risk of data loss of a virtual machine and further improve the stability of the virtual machine, the embodiment of the application provides a control method for information consistency of a virtualization platform.
Fig. 1 is a flowchart of a control method for virtualization platform information consistency according to an embodiment of the present application, and as shown in fig. 1, the method is applied to a management node, and includes:
s10: and creating a task to be executed, and issuing the task to be executed to the computing node.
In a specific embodiment, when the virtualization platform needs to perform operations such as migration, backup and snapshot on the virtual machine, the management node creates a task to be executed, and issues the created task to the computing node, and the computing node executes the task created on the virtual machine to obtain an execution result. The tasks to be executed include a virtual machine disk migration task, a virtual machine backup task and a virtual machine snapshot task, and specific contents of the tasks to be executed are not limited in the present application.
S11: and acquiring an execution result obtained by executing the task to be executed by the computing node.
S12: and detecting whether the actual information of the corresponding target virtual machine after the computing node executes the task to be executed is consistent with the information of the target virtual machine in the database managed by the current management node according to the execution result, and if not, entering step S13.
S13: and carrying out information synchronization operation on the information of the target virtual machine in the database by taking the actual information of the target virtual machine as a reference.
In order to avoid failure in issuing a task to be executed due to phenomena such as communication abnormality or packet loss, or in executing the task to be executed by a computing node, a management node acquires an execution result obtained after the computing node executes the task, detects whether actual information of a corresponding target virtual machine after the computing node executes the task to be executed is consistent with information of the target virtual machine in a database managed by the current management node according to the execution result, and if the actual information of the target virtual machine in the bottom layer is not consistent, performs synchronous operation on the information of the target virtual machine in the database by taking the actual information of the target virtual machine in the bottom layer as a reference.
It can be understood that the virtualization platform may operate multiple virtual machines, and when the management node creates a task, it may operate one virtual machine or multiple virtual machines, and therefore, the target virtual machine refers to a virtual machine corresponding to a task to be executed, which is created by the management node.
It should be noted that the execution result of the phase node execution may be a successful execution or a failed execution, and the step S12 is performed to detect whether the upper and lower layers of the virtualization platform are consistent. It should be noted that the upper-lower layer consistency of the virtualization platform refers to consistency between information of a virtual machine in a database managed by an upper management node and actual information of the virtual machine after a bottom computing node executes a task, and the meaning of the upper-lower layer consistency of the virtualization platform is not described in detail below. In addition, the virtual machine information refers to information such as configuration information of the virtual machine, a CPU on which the virtual machine operates, and storage information and status of a disk of the virtual machine.
After the computing node executes the task to be executed to obtain the execution result, the management node may not obtain the execution result due to network anomaly or packet loss, and the like, so that when it is determined that the execution result is failed to obtain, the management node starts an inquiry thread, inquires the actual information of all the virtual machines after the computing node executes the task to be executed, detects whether the actual information of all the virtual machines is consistent with the information of all the virtual machines stored in the database, and if not, performs synchronous operation on the information of the virtual machines in the database by taking the inquiry result as a reference.
When the computing node executes the task to be executed, in order to avoid the target virtual machine being occupied by other tasks, the resources of the target virtual machine are locked before the task to be executed is executed, and the resources of the target virtual machine are released after the task is executed.
In order to avoid the failure of executing the task due to the fault of the virtual machine, whether the virtual machine is normal or not is detected before the task is executed, and if the virtual machine is abnormal, an abnormal signal is transmitted to the terminal, so that a user can check and eliminate the abnormality in time.
According to the technical scheme provided by the embodiment of the application, all the virtual machine information is queried once every other preset time and is compared with the virtual machine information in the upper database, so that the consistency of the upper and lower information of the virtualization platform is ensured.
In fact, in addition to the technical solution provided by the present application, the present application is not limited to this, and the present application can be applied to an application scenario with virtualization platform information consistency, and can also be applied to a scenario in which any execution service and storage service are not on the same side.
The control method for information consistency of the virtualization platform provided by the embodiment of the application is applied to a management node, and comprises the following steps: and creating a task to be executed, issuing the created task to be executed to the computing node, and acquiring an execution result obtained by the computing node executing the task to be executed. And detecting whether the actual information of the corresponding target virtual machine after the computing node executes the task to be executed is consistent with the information of the target virtual machine in the database managed by the current management node or not according to the execution result, and if not, performing information synchronization operation on the information of the target virtual machine in the database by taking the actual information of the target virtual machine as a reference. Therefore, according to the technical scheme provided by the application, the actual information of the target virtual machine corresponding to the bottom-layer computing node after executing the task to be executed is compared with the information of the virtual machine recorded in the database, and when the information of the virtual machine is inconsistent, the virtual machine information in the database is synchronized by taking the actual information of the bottom-layer target virtual machine as a reference, so that the inconsistency of upper-layer information and lower-layer information of a virtualization platform is avoided, namely the inconsistency of the virtual machine information in the database and the virtual machine information corresponding to the computing node after executing the task is avoided, the data loss risk of the virtual machine is reduced, and the system stability is improved.
In a specific embodiment, when the management node obtains the execution result of the computing node, it may fail to obtain the information of the upper and lower layers of the virtualization platform due to network anomaly or packet loss, and if the obtaining fails, it is unable to detect the consistency of the information of the upper and lower layers of the virtualization platform, so before detecting whether the actual information of the corresponding target virtual machine after the computing node executes the task is consistent with the information of the target virtual machine in the database managed by the current management node according to the execution result, it is determined whether to obtain the execution result sent by the computing node, if the actual information is obtained, the upper and lower layer information consistency detection is performed on the virtualization platform, if the actual information is not obtained, the management node triggers an inquiry thread to inquire the actual information of all the virtual machines after the computing node executes the task, and compares the inquired information with the information of each virtual machine in the database managed by the current management node, and if the information is inconsistent, synchronizing the virtual machine information in the database by taking the actual information of each inquired virtual machine as a reference.
It can be understood that if the management node obtains the execution result, it is not necessary to start the query thread to perform query, and further it is not necessary to perform query on all virtual machines, thereby avoiding resource waste.
According to the control method for information consistency of the virtualization platform, before whether actual information of a corresponding target virtual machine after a computing node executes a task to be executed is consistent with information of the target virtual machine in a database managed by a current management node is detected according to an execution result, whether the execution result is obtained is determined, if the execution result is not obtained, actual information of all virtual machines after the computing node executes the task to be executed is inquired, whether the actual information of all the virtual machines is consistent with the information of all the virtual machines in the current database is detected, and if the actual information of all the virtual machines is not consistent with the information of all the virtual machines in the current database, information synchronization operation is carried out on the information of all the virtual machines in the current database by taking the inquired actual information of all the virtual machines as a reference. And if the information is acquired, detecting the consistency of the upper layer information and the lower layer information of the virtualization platform according to the execution result. Therefore, when the management node acquires the execution result of the computing node, the failure of acquisition caused by network abnormity or packet loss and other phenomena is avoided, the failure of detection of upper and lower information of the virtual machine platform is further caused, and the stability of the virtual machine is reduced.
It can be understood that, when a computing node executes an operation on a target virtual machine, if other tasks need to occupy the target virtual machine, the task to be executed may be failed to be executed, for example, when different tasks write a same target virtual machine disk, data that needs to be written by the task to be executed may be covered by other tasks, thereby causing the task to be executed to fail, and further increasing a risk that the virtual machine loses data.
Therefore, in order to reduce the risk of data loss of the virtual machine, in the method provided in the embodiment of the present application, before the execution result obtained by the computing node executing the task to be executed, the resource of the target virtual machine corresponding to the task to be executed is locked, and after the execution result obtained by the computing node executing the task to be executed, the resource of the target virtual machine is released.
According to the control method for information consistency of the virtualization platform, before the execution result obtained by the computing node executing the task to be executed is obtained, the resources of the target virtual machine corresponding to the task to be executed are locked, and after the execution result obtained by the computing node executing the task to be executed is obtained, the resources of the target virtual machine are released, so that the problem that the execution of the task to be executed fails due to the fact that other tasks occupy the resources of the target virtual machine is avoided, the consistency of information of the upper layer and the lower layer of the virtualization platform is further guaranteed, and the stability of the virtual machine is improved.
On the basis of the above embodiment, in order to further improve the consistency of information of upper and lower layers of the virtualization platform, each preset time length is called to invoke an inquiry thread to execute the actual information of all the virtual machines after the inquiry computing node executes the task to be executed once, whether the actual information of each virtual machine is consistent with the information of each virtual machine in the current database or not is detected, and if not, the information of the virtual machines in the database is synchronously operated according to the actual information of the inquired virtual machines, namely, the updating operation is performed.
It should be noted that a preset time is set, and after the preset time is reached along with the lapse of time, information query of the virtual machine is performed once, that is, consistency detection of information of upper and lower layers of the virtualization platform is performed once, so that failure of the computing node in executing a task next time due to inconsistency of information of the upper and lower layers when the computing node does not execute the task is avoided.
In addition, it should be noted that, when the information of the upper layer and the lower layer of the virtualization platform is inconsistent, if synchronization cannot be completed according to the actual information of the underlying virtual machine, that is, when the database information fails to be updated, the abnormal state is transmitted to the client, so that the user can check and eliminate the abnormality. According to the control method for the information consistency of the virtualization platform, whether the actual information of all the virtual machines after the computing node executes the task to be executed is consistent with the information of all the virtual machines in the current database or not is inquired every other preset time, namely whether the information of the upper layer and the lower layer of the virtualization platform is consistent or not is detected, the data loss rate of the virtual machines is further reduced, and the stability of the system is improved.
In fact, the execution result of the compute node obtained by the management node may be successful in execution or may be failed in execution, and the failure in execution may be caused by an exception occurring in the virtual machine itself, so as to avoid inconsistency of information of upper and lower layers of the virtualization platform due to this phenomenon, and therefore, before the resource of the target virtual machine corresponding to the task to be executed is locked, it is determined whether the virtual machine is abnormal, and if the virtual machine is abnormal, the execution of the task to be executed is terminated, and an abnormal signal is transmitted to the client.
Meanwhile, in order to further improve the consistency of the information of the upper layer and the lower layer of the virtualization platform, after the target virtual machine is determined to be abnormal, the consistency of the information of the upper layer and the lower layer of the virtualization platform is detected once, namely, a query thread is called to query the actual information of all the virtual machines on the bottom layer, and the actual information is compared with the information of all the virtual machines in the database.
According to the control method for the information consistency of the virtualization platform, before the resources of the target virtual machine corresponding to the task to be executed are locked, whether the virtual machine is abnormal or not is determined, so that the failure of the computing node in executing the task due to the abnormal virtual machine is avoided, the stability of the virtual machine is further improved, and the information consistency of the upper layer and the lower layer of the virtualization platform is further improved.
In a specific embodiment, the tasks to be executed at least include a virtual machine disk migration task, a virtual machine backup task, and a virtual machine snapshot task, and the tasks to be executed are not limited in this application. For ease of understanding, the task to be executed is taken as an example of a virtual machine disk migration task.
For example, the management node issues a virtual machine disk migration task, the disk D1 of the target virtual machine VM1 is migrated from the source storage a to the destination storage B, and after the disk D1 is migrated to the destination storage B, the disk of the target virtual machine VM1 is D2. The specific migration steps are as follows:
s1: creating a disk migration task of the target virtual machine VM1, and transmitting the disk migration task to the computing node for execution;
s2: detecting whether the target virtual machine VM1 is abnormal, if so, entering a step S3, and if so, entering a step S4;
s3: stopping the migration task, transmitting an abnormal signal to the client, calling a query thread to query actual information of all virtual machines after the computing node executes the task to be executed, detecting whether the actual information of each virtual machine is consistent with the information of each virtual machine in the current database, and if the actual information of each virtual machine is not consistent with the information of each virtual machine in the current database, performing information synchronization operation on the information of each virtual machine in the current database by taking the queried actual information of each virtual machine as a reference;
s4: acquiring an execution result of the computing node after executing the disk migration task of the target virtual machine VM 1;
s5: determining whether an execution result is acquired, if so, executing a step S6, and if not, executing a step S7;
s6: detecting whether the actual information of the corresponding target virtual machine VM1 disk D1 after the computing node executes the task to be executed is consistent with the information of the target virtual machine VM1 disk D1 in the database managed by the current management node or not according to the execution result, and if not, entering the step S8;
s7: inquiring the actual information of all virtual machines after the computing node executes the task to be executed, detecting whether the actual information of each virtual machine is consistent with the information of each virtual machine in the current database, and if not, carrying out information synchronization operation on the information of each virtual machine in the current database by taking the actual information of each inquired virtual machine as a reference;
s8: and performing information synchronization operation on the information of the disk D1 of the target virtual machine VM1 in the database by taking the actual information of the disk D1 of the target virtual machine VM1 after migration as a reference.
It is worth noting that when a virtual machine disk migration task is executed and a virtual machine disk deletion operation is executed, a disk recycle logic is added, after a disk D1 of a target virtual machine VM1 is migrated from a source storage a to a destination storage B, a disk D1 in the source storage a is logically deleted, that is, the disk D1 is moved to a recycle bin corresponding to the source storage a, a preset retention time T is set, and the disk D1 is physically deleted (actually deleted) after the preset time T. And if the disk migration task of the virtual machine is determined to be abnormal within the preset time length T, recovering the disk D1 from the recycle bin corresponding to the source storage A.
Therefore, after the computing node executes the migration task of the target virtual machine VM1 disk D1, if the upper and lower layer information of the virtualization platform are consistent, the task is ended, the disk D1 is physically deleted after the preset time length T, and the recovery record is cleared. If the upper and lower layer information of the virtualization platform are inconsistent, the following conditions exist:
(1) the disk D1 of the bottom-layer target virtual machine VM1 is in a source storage A, the disk D1 of the target virtual machine VM1 in a database managed by a management node is in a destination storage B, the disk D1 in a recycle bin corresponding to the source storage A is recovered, the disk D2 is marked as a recoverable disk D2, and in addition, information in the database is updated to the disk D1 of the target virtual machine VM1 in the source storage A. It should be noted that if it is determined that the recovery disk D1 fails, a recovery failure signal is transmitted to the client.
(2) In the destination storage B, the disk D1 of the bottom-layer target virtual machine VM1 is in the destination storage B, the disk D1 of the target virtual machine VM1 in the database managed by the management node is in the source storage a, the disk D2 in the recycle bin is recovered, the disk D1 is marked as recoverable, then the disk D1 is physically deleted, besides, the information in the database is updated to the disk D1 of the target virtual machine VM1 in the destination storage B, and similarly, if it is determined that the disk D2 fails to be recovered, a recovery failure signal is transmitted to the client.
(3) When the disk D1 of the bottom-layer target virtual machine VM1 is in the source storage a or the destination storage B, but the database does not have the disk information of the target virtual machine VM1, according to the storage information of the disk D1 of the bottom-layer target virtual machine VM1, the disk D1 or the disk D2 is recovered, the disk D1 or the disk D2 is marked as recyclable and then physically deleted, in addition, the information in the upper-layer database is synchronized to be the same as the information in the bottom layer, and of course, if the recovery of the disk fails, a recovery failure signal needs to be transmitted to the client.
(4) When the disk information of the target virtual machine VM1 exists in the database, the target virtual machine VM1 is closed, the target virtual machine VM1 is set to be abnormal, and an abnormal signal is transmitted to the client.
