Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Next, a method for verifying virtualized disk data according to an embodiment of the present invention is described in detail. Fig. 1 is a flowchart of a method for verifying virtualized disk data according to an embodiment of the present invention, where the method includes:
s101: and calculating a first check value of the real data in the virtualized disk file.
The virtual disk file comprises management data and real data. Real data refers to disk data seen inside the virtual machine.
Common virtualized disk file formats include raw, qcow2, vmdk, and vhd. In the embodiment of the present invention, the virtualized disk file may be indexed according to the file format to obtain the real data.
Taking the qcow2 file format as an example, as shown in fig. 2, which is a schematic diagram of the qcow2 file format, without considering the internal snapshot, the qcow2 file includes a file header, an L1 table, and an L2 table DataBlocks, where the DataBlocks represent real disk data, that is, disk data seen inside the virtual machine. The header, L1 table, and L2 table are management data set to enable access to real disk data and to organize the disk data. As can be seen from fig. 2, the L1 Table (L1 Table) contains multiple rows of information, and each row of information corresponds to one L2 Table (L2 Table). Each L2 table contains multiple lines of information, typically each line of information having its corresponding DataBlocks. In practical applications, according to the qcow2 file format, real data (DataBlocks) can be extracted from the qcow2 file.
In practical application, a virtualized disk file may undergo processing such as copying, conversion, snapshot, or migration, and in order to ensure consistency of data before and after processing, the virtualized disk file needs to be verified. In view of the fact that the processing operation of the virtualized disk file does not affect the real data seen inside the virtual machine, in the embodiment of the present invention, the consistency check before and after the processing of the virtualized disk file is realized by calculating the check value of the real data.
For convenience of distinction, in the embodiment of the present invention, real data of a virtualized disk file before processing may be referred to as first real data, and a check value of the first real data may be referred to as a first check value. Accordingly, the real data of the virtualized disk file after processing may be referred to as second real data, and the check value of the second real data may be referred to as a second check value.
There are various ways to calculate the check value, and one way may be to calculate the MD5 value of the real data by using a Message Digest (MD). Specifically, the virtualized disk file may be indexed according to a file format to obtain first real data; a first MD5 value for the first real data is calculated and the first MD5 value is taken as the first check value.
Another way may be to use a Secure Hash Algorithm (SHA) to compute the Hash of the real data. Specifically, the virtualized disk file may be indexed according to a file format to obtain first real data; and calculating a first hash value of the first real data, and taking the first hash value as a first check value.
In the embodiment of the present invention, the manner of calculating the check value is not limited, and it is only required to ensure that the check value is calculated in the same manner for the virtualized disk file before and after processing, for example, when the first real data is calculated by using the SHA algorithm, the check value is correspondingly calculated for the second real data by using the SHA algorithm.
It should be noted that uninitialized data and initialized zero-writing data exist in the virtualized disk file. Taking the qcow2 file as an example, the uninitialized data means that no pointer points to data in the L2 table, that is, there is no corresponding DataBlocks in the line data in the L2 table, and when calculating the check value, the real data corresponding to the line can be processed according to zero data. Initializing zero-writing data means that a pointer points to data in the L2 table, but the pointed data takes a value of zero, that is, DataBlocks corresponding to row data in the L2 table are zero. When the check values of all real data in the virtualized disk file are calculated, uninitialized data and initialized zero-writing data can be processed according to zero data, so that possible data compression or deletion can be prevented when qemu-img performs copying, conversion, snapshot and migration operations on the virtualized disk file.
S102: and after the processing of the virtualized disk file is finished, calculating a second check value of the real data in the processed virtualized disk file.
In practical applications, the conventional process of virtualizing a disk file may include: and performing file format conversion on the virtualized disk file or performing convert operation on data on the virtualized disk file.
The convert operation refers to an operation for reducing the file volume, and includes eliminating redundant data of a virtualized disk file or eliminating a snapshot chain.
Taking MD5 as an example, after processing of the virtualized disk file is completed, the virtualized disk file may be indexed according to the current file format of the virtualized disk file after the processing is completed, so as to obtain second real data; a second MD5 value for the second real data is calculated and the second MD5 value is taken as a second check value.
Taking the SHA algorithm as an example, after the processing of the virtualized disk file is completed, indexing the virtualized disk file according to the current file format of the processed virtualized disk file to obtain second real data; and calculating a second hash value of the second real data, and using the second hash value as a second check value.
S103: and judging whether the first check value and the second check value are equal or not.
In the embodiment of the invention, whether the processing of the virtualized disk file damages the real data can be judged by judging whether the check values of the real data before and after the processing are consistent.
When the first check value is equal to the second check value, it indicates that the real data of the virtualized disk file before and after the processing has not changed and is not damaged, and at this time, S104 may be executed.
When the first check value is not equal to the second check value, it indicates that the real data of the virtualized disk file has changed before and after the processing, and the processing on the virtualized disk file destroys the real data, and at this time, S104 may be executed.
S104: and judging that the real data in the processed virtualized disk file is available data.
S105: and judging that the real data in the processed virtualized disk file is unavailable data.
In the embodiment of the present invention, when the first check value is not equal to the second check value, it is determined that the real data in the processed virtualized disk file is unavailable data, and in order to avoid an influence caused by data inconsistency, the processed virtualized disk file may be deleted.
According to the technical scheme, the first check value of the real data in the virtualized disk file is calculated; the virtual disk file comprises management data and real data; after the virtualized disk file is processed, calculating a second check value of real data in the processed virtualized disk file; judging whether the first check value is equal to the second check value; when the first check value is equal to the second check value, it indicates that the real data before and after the processing of the virtualized disk file does not change, and at this time, it may be determined that the real data in the processed virtualized disk file is usable data; when the first check value is not equal to the second check value, it indicates that the real data in the processed virtualized disk file has changed, and the real data before processing and the real data after processing do not meet the requirement of consistency, and at this time, it may be determined that the real data in the processed virtualized disk file is unavailable data. By acquiring the real data of the virtualized disk file and calculating the check value of the real data, the check process is not influenced by operation processing such as format conversion of the virtualized disk file, redundant data discarding and the like, and consistency check of the virtualized disk file before and after processing is realized.
