[0095] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0096] refer to Figure 1 , Figure 1 1 is a flow chart of a data verification method proposed in one embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0097] S11: Generate a corresponding disk configuration list according to the virtual disk function corresponding to the cloud host on the cloud platform.

[0098] In this embodiment, the cloud platform is a cloud computing platform, which is a hardware-based service that provides computing, network and storage capabilities. The cloud platform is mainly divided into a storage-type cloud platform that focuses on data storage, a computing-type cloud platform that focuses on data processing, and a comprehensive cloud computing platform that takes both computing and storage into account. Cloud computing is to assign tasks submitted by users to a resource pool composed of a data center server cluster. The system provides corresponding computing capabilities, storage space or various software services according to the needs of users. Server virtualization is to create various hardware through software definition, so as to realize the simultaneous operation of several independent cloud hosts on a hardware platform. Each cloud host uses an independent central processing unit, hard disk, memory, data input and output port, network card and other hardware devices. At the same time, different operating systems can be installed on the cloud host to meet the various needs of different users. Cloud server is a simple, efficient, safe and reliable computing service with elastic processing power. The management method of cloud server is simpler and more efficient than that of physical server. Users can create customized cloud hosts for deployment and use of related applications by making relevant applications on the cloud platform.

[0099] In this embodiment, the virtual disk is implemented based on storage virtualization technology. Storage virtualization technology combines multiple physical storage devices into a virtual storage device, thereby providing higher storage efficiency and reliability. Storage virtualization integrates the capacity and performance of physical storage devices to form a virtual storage pool. Data can be freely moved between different physical storage devices, thereby optimizing storage utilization and performance. A new virtual disk is created in the storage pool and mounted to the cloud host. The cloud host can use the virtual disk to set the corresponding disk policy, disk format, disk interface, disk read and write mode, start asynchronous IO, enable kernel IO acceleration, etc. Through different configurations, the host IO read and write capabilities can be more fully realized. The cloud host runs on the physical server of the cloud platform. When the cloud host is running, the corresponding task data runs in the memory space of the physical server, and the data is not written to the storage pool hard disk. In addition, the cloud host management capabilities provided by the cloud platform, including hot editing of cloud hosts, cross-cloud platform migration, DRS (Data Replication Servic) migration, snapshots, backups and other functions, may affect the reading and writing of cloud host data. Therefore, it is necessary to consider the data integrity of the cloud platform's virtual disk under various operations to ensure that data is not lost. Data loss will affect the operation and calculation of the cloud platform, and then affect the services provided by the cloud platform to users. Therefore, when verifying data integrity, it is necessary to take various possible operations and combined operations into consideration.

[0100] In this embodiment, the disk configuration list lists various function configurations supported by the disk one by one in a table.

[0101] In this embodiment, the host virtual disk configuration management device generates a corresponding disk configuration list according to the virtual disk functions corresponding to the cloud host on the cloud platform. The list lists the functions of the virtual disks supported by the cloud host one by one. The functions of each virtual disk are not exactly the same and need to be determined based on the actual supported virtual disks.

[0102] In this embodiment, the specific steps of generating a corresponding disk configuration list according to the virtual disk function corresponding to the cloud host on the cloud platform by the host virtual disk configuration management device include:

[0103] S11 - 1 : Determine disk configuration parameters of the virtual disk corresponding to the cloud host according to the virtual disk function corresponding to the cloud host.

[0104] In this embodiment, the disk configuration parameters are specific configuration parameters of the virtual disk, including but not limited to disk type, disk policy, disk format, disk interface, read / write policy, setting the number of queues, enabling kernel io, asynchronous io, sharing, locking and other configurations.

[0105] In this embodiment, each cloud host supports different types of virtual disks with different configurations. The function of the virtual disk corresponding to the cloud host is determined based on the virtual disk information stored in the cloud host, and then the disk configuration parameters of the virtual disk corresponding to the cloud host are determined.

[0106] In this embodiment, after the functions of the virtual disk corresponding to the cloud host are determined, the supported functions are counted, integrated, and listed one by one. The integrated data is the disk configuration parameters of the virtual disk.

[0107] For example, disk types include virtual disks and raw device disks, disk policies include thin provisioning and non-thin provisioning, disk formats include RAW, QCOW2 and other formats, disk interfaces include VIRTIO, SCSI (Small Computer System Interface), IDE (Integrated Drive Electronics) and other interfaces, and read and write policies include writeback, writethrough, none, directsync and other policies. Different types of configurations support some operations, but not others. For example, virtio supports setting the number of queues; iscsi and ide do not support setting the number of io queues; none and directsync support opening kernel io, but writethrough and writeback do not support kernel io.

[0108] S11 - 2: storing the disk configuration parameters one by one in a list to obtain the disk configuration list.

[0109] In this embodiment, after obtaining the specific configuration parameters of the virtual disk corresponding to the cloud host, the disk configuration parameters are stored one by one in an empty list. After the storage is completed, the list is used as the disk configuration list.

[0110] S12: Generate a corresponding operation list according to the preset cloud host operation weights and cloud host operation mutual exclusion rules.

[0111] In this embodiment, the cloud host operation weight is a weight set for each cloud host operation. The weight setting is based on the impact of the operation on data integrity. The greater the impact, the higher the weight of the operation. The impact of the cloud host operation on the cloud host data integrity is obtained by collecting and integrating the operation data of the cloud host during normal operation. The host operation mutual exclusion rule means that some operations cannot be performed at the same time, that is, when the virtual disk performs some operations, it cannot perform other operations, and some operations conflict with each other.

[0112] In this embodiment, a corresponding operation list is generated according to the preset cloud host operation weights and cloud host operation mutual exclusion rules. When generating the operation list, each single operation is set with a corresponding weight, and then multiple target weights are set in order from small to large. Under the premise of following the cloud host operation mutual exclusion rules, the single operations are combined according to the weights to obtain the combined operations corresponding to the target weights. Then the corresponding operation list is generated.

[0113] In this embodiment, the specific steps of generating a corresponding operation list according to the preset cloud host operation weights and cloud host operation mutual exclusion rules include:

[0114] S12-1: Read the cloud host operation weight of each cloud host operation supported by the cloud host.

[0115] In this embodiment, when generating the operation list, the cloud host operation weight of each cloud host operation supported by the cloud host is first read.

[0116] S12-2: Combining the cloud host operations according to the cloud host operation mutual exclusion rule and the cloud host operation weight to obtain at least one combined operation.

[0117] In this embodiment, cloud host operations are combined according to the cloud host operation mutual exclusion rules and cloud host operation weights to obtain at least one combined operation. Generally, as long as the operation mutual exclusion rules are not affected, multiple cloud host operations can be combined into multiple combined operations.

[0118] In this embodiment, the specific steps of combining the cloud host operations according to the cloud host operation mutual exclusion rule and the cloud host operation weight to obtain at least one combined operation are:

[0119] S12-2-1: Set the target weight value.

[0120] In this embodiment, the target weight value is a target value set for combining operations, and is the basis for combining operations.

[0121] In this embodiment, in order to combine cloud host operations to simulate the situation where the cloud host virtual disk performs multiple combined operations during actual operation, a target weight value is set, and the target weight value can be increased in sequence until there is no satisfied combined operation.

[0122] S12-2-2: According to the target weight value, the cloud host operations are combined to obtain the combined operation.

[0123] In this embodiment, according to the target weight value, any number of cloud host operations are combined to obtain multiple combined operations. When combining the operations, the weight values ​​corresponding to the any number of cloud host operations are added together, and when the weight value is equal to the target weight value, the corresponding combined operation is determined.

[0124] In this embodiment, the cloud host operations are combined according to the target weight value to obtain the specific steps of the combined operation including:

[0125] S12-2-2-1: Combine the cloud host operation weights corresponding to any plurality of the cloud host operations so that the combined weight value is equal to the target weight value.

[0126] In this embodiment, the cloud host operation weights corresponding to any multiple cloud host operations are combined so that the combined weight value is equal to the target weight value. When combining, the weight of a single cloud host operation is determined, and then the weight values ​​of the multiple cloud host operations to be combined are added. When the added weight value is equal to the target weight value, the combination is completed.

[0127] S12-2-2-2: When the combined weight value is equal to the target weight value, the corresponding multiple cloud host operations are regarded as one combined operation.

[0128] In this embodiment, when the combined weight value is equal to the target weight value, the operation formed by combining the corresponding multiple cloud host operations is regarded as a combined operation.

[0129] S12-3: Add each of the cloud host operations and the combined operations that comply with the cloud host operation mutual exclusion rule to a list to obtain the operation list.

[0130] In this embodiment, each cloud host operation is added as a separate operation to a newly created list, and combined operations that meet the mutual exclusion rule of cloud host operations are added to the list to obtain a corresponding operation list.

[0131] In this embodiment, the weight value is read by the operation generation device, and the corresponding operation is selected according to the weight value. The corresponding weight value is defined according to the operations supported by the cloud platform and the operations that affect the cloud host io reading and writing. At the same time, according to the preset rules, each operation is required to be different.

[0132] For example, weight values ​​are set for the following operations:

[0133] Cross-cloud platform migration: Weight 20

[0134] Calculation migration: weight 20

[0135] Storage migration: weight 20

[0136] Migrate the entire machine: Weight 20

[0137] Backup: Weight 40

[0138] Snapshot: Weight 40

[0139] Hot-add virtual disk: weight 50

[0140] The operation generation device reads the weight value 20, and the operation list that can be generated includes 3 types. The weight value 60, and the operation list that can be generated includes 12 types, such as computing migration 20+backup 40, storage migration 20+snapshot 40, etc., which are all combined operations.

[0141] S13: Obtain at least one operation use case corresponding to the cloud host according to the disk configuration list and the operation list.

[0142] In this embodiment, a use case is a description of how a system responds to external requests in software engineering or system engineering. It is a technique for obtaining requirements through user usage scenarios. Each use case provides one or more scenarios that illustrate how the system interacts with end users or other systems, that is, who can use the system to do what, so as to obtain a clear business goal.

[0143] In this embodiment, after obtaining the disk configuration list and the operation list, at least one operation use case corresponding to the cloud host is obtained. The disk configuration list lists the functional configurations of the virtual disk, and the operation list lists the corresponding operations. Each functional configuration combined with an operation is a use case.

[0144] In this embodiment, at least one operation use case corresponding to the cloud host is obtained according to the disk configuration list and the operation list. The specific steps include:

[0145] S13 - 1 : For each virtual disk configuration in the disk configuration list, select a corresponding cloud host operation and a combination operation in the operation list.

[0146] In this embodiment, for each virtual disk configuration in the disk configuration list, a corresponding host operation and a combination operation are selected in the operation list.

[0147] In this embodiment, generally, each virtual disk configuration can form a use case with any operation or combination of operations.

[0148] S13-2: Obtain the operation use case according to the virtual disk configuration, the cloud host operation and the combined operation.

[0149] In this embodiment, after determining the virtual disk configuration and the corresponding cloud host operation or combined operation, the use case device combines the two to obtain the corresponding operation use case.

[0150] In this embodiment, each configuration in the configuration list and any operation or combination of operations in the operation list can be combined into a use case. Therefore, the number of operation use cases can be obtained by multiplying the number of configurations by the number of operations in the operation list.

[0151] S14: When the cloud host executes the operation use case, data verification is performed on the pre-operation data and the post-operation data of the cloud host to obtain a comprehensive verification result.

[0152] In this embodiment, the pre-operation data is the data in the virtual disk before the cloud host executes the operation use case, and the post-operation data is the data stored in the virtual disk after the cloud host executes the operation use case. The comprehensive verification result is a comprehensive evaluation result of the data integrity obtained by combining the integrity of the pre-operation data and the integrity of the post-operation data.

[0153] In this embodiment, when the cloud host executes the operation use case, data verification is performed on the pre-operation data and the post-operation data of the cloud host to obtain a comprehensive verification result. The specific steps include:

[0154] S14-1: When the cloud host starts to execute the operation use case, read the pre-operation data.

[0155] In this embodiment, when the cloud host starts to execute the operation use case, the data verification device receives the corresponding notification and writes the data before the cloud host operation.

[0156] S14-2: Verify the pre-operation data to obtain a first verification result.

[0157] In this embodiment, the data verification device verifies the pre-operation data to obtain a first verification result, which represents the integrity of the pre-operation data.

[0158] S14-3: When the cloud host completes executing the operation use case, the post-operation data is obtained.

[0159] In this embodiment, when the cloud host completes the operation use case, the data verification device receives a corresponding notification and obtains the post-operation data.

[0160] S14-4: Verify the operated data to obtain a second verification result.

[0161] In this embodiment, the data verification device verifies the post-operation data to obtain a second verification result, which represents the integrity of the post-operation data.

[0162] S14-5: Use the first verification result and the second verification result as the comprehensive verification result.

[0163] In this embodiment, after the first verification result and the second verification result are obtained, the two results are combined to obtain a comprehensive verification result.

[0164] For example, data verification can use verification methods such as MD5 verification, which are not limited here. If the first result and the second result both indicate that the corresponding data is complete, the comprehensive verification result indicates that the cloud host can ensure data integrity when executing the use case. If any one or both of the first result and the second result has incomplete data, the comprehensive verification result indicates that the data is incomplete.

[0165] In this embodiment, the method further includes:

[0166] S14-6: Determine whether the operation use case has an impact on the data integrity of the cloud host based on the comprehensive verification result.

[0167] In this embodiment, after obtaining the comprehensive verification result, it is determined whether the corresponding operation use case has an impact on the data integrity of the cloud host according to the obtained comprehensive verification result. If the comprehensive verification result indicates that the data is incomplete, it means that the operation use case has affected the data integrity of the host. If the comprehensive verification result indicates that the data is complete, it means that the operation use case has not affected the data integrity of the host.

[0168] S14-7: When the operation case affects the data integrity of the cloud host, mark the operation case as an abnormal operation.

[0169] In this embodiment, when an operation case affects the data integrity of the cloud host, the operation case is marked as an abnormal operation. The operation case marked as an abnormal operation will affect the integrity of the host data, and the code corresponding to the operation needs to be adjusted to ensure the integrity of the cloud platform data.

[0170] In another embodiment of the present application, before the cloud host executes the operation use case, the method further includes:

[0171] S21: Parse the operation use case to obtain a cloud host configuration corresponding to the operation use case.

[0172] In this embodiment, before the cloud host executes the operation case, the operation case is parsed to obtain the cloud host configuration corresponding to the operation case. The cloud host configuration corresponding to the operation case is the host configuration that needs to be satisfied to execute the operation case.

[0173] S22: Creating the cloud host satisfying the cloud host configuration on the cloud platform.

[0174] In this embodiment, before executing the operation use case in the cloud host on the cloud platform, a cloud host that meets the configuration of the cloud host is created on the cloud platform. Only after the host is created can the corresponding operation use case be run.

[0175] In this embodiment, the method further includes:

[0176] S23: Perform resource determination on the operation use case to determine whether the resources in the cloud platform meet the execution of the operation use case.

[0177] In this embodiment, after the cloud host is created, resource information in the cloud platform is obtained, and a resource determination is performed on the operation use case to determine whether the resources in the cloud platform meet the execution of the operation use case.

[0178] In this embodiment, the method further includes:

[0179] S24: When the resources in the cloud platform satisfy the execution of the operation use case, the operation use case is executed through the cloud host.

[0180] In this embodiment, when the resources in the cloud platform meet the execution requirements of the operation, the corresponding operation use case is started to be executed on the cloud host.

[0181] In this embodiment, the method further includes:

[0182] S25: When the resources in the cloud platform do not satisfy the execution of the operation use case, stop executing the operation use case.

[0183] In this embodiment, when the resources of the cloud platform do not meet the execution of the operation use case, the execution of the operation use case is stopped until the resources of the cloud platform are released and the execution of the operation use case is met, and then the corresponding operation use case is executed.

[0184] S26: Generate corresponding abnormal information.

[0185] In this embodiment, when the operation use case cannot be executed normally, corresponding exception information is generated.

[0186] S27: Record the abnormal information in the system log.

[0187] In this embodiment, after the exception information is generated, the exception information is recorded in the system log to facilitate the tester to review.

[0188] In another embodiment of the present application, when it is detected that a certain operation use case has an impact on the data integrity of the cloud platform, it is necessary to check the configuration and operation corresponding to the operation use case to see where the problem occurs. If there is a problem with the configuration, modify the corresponding configuration parameters. If there is a problem with the cloud platform operation, adjust the code corresponding to the operation, or adjust the calling relationship between different codes in the combined operation to adjust the operation. After the adjustment is completed, re-execute the corresponding operation use case through the cloud host on the cloud platform. If the data before and after the operation of the operation use case are complete, the corresponding configuration and operation adjustment are complete.

[0189] refer to Figure 2 , Figure 2 : is a schematic diagram of a cloud host data integrity check process proposed in an embodiment of the present application, such as Figure 2 As shown, first, the configuration parameters of the cloud host are obtained through the configuration management device, and a corresponding configuration list is generated according to the configuration parameters. At the same time, the operation generation device generates a corresponding operation list according to the corresponding operation mutual exclusion rules and weight values. The use case device obtains the corresponding operation use case according to the operation list and the configuration list, and accesses the cloud platform at the same time to determine whether the current use case environment satisfies the execution of the use case. When the use case environment satisfies the execution of the use case, the corresponding use case is executed. Before and after the execution, the verification device verifies the integrity of the pre-operation data and the post-operation data. Finally, the results are collected and the process ends.

[0190] In the above embodiment of the present application, the virtual disk configuration of the cloud host and the operations that affect the data IO reading and writing are separated to obtain a configuration list and an operation list respectively. The configuration is selected by classification, and the operation is selected by weight value. The configuration and operation are combined into a use case for testing, and data integrity verification is performed before and after each operation to minimize the damage to data integrity caused by a certain operation in the operation list of the test virtual disk configuration, so as to achieve automated testing, be able to fully cover the configuration and specified operations, reduce omissions in manual testing, and quickly improve the efficiency of testing. The configuration management device only needs to add configuration items, and the operation generation device only needs to add operation assignments and weights, and the operation list can be regenerated by modifying the incoming weight value, which facilitates the testing of cloud platforms with different configurations, enables the test method to be applied on different cloud platforms, and improves the efficiency of testing.
