Detailed Description
The embodiment of the invention provides a method, a device and a system for realizing cloud application of mirror image volume data and a computer readable storage medium, which can realize cloud application of the mirror image volume data and combination of mirror image and cloud backup on the basis of ensuring consistency of data before and after cloud application in a using process.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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 invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for implementing cloud sharing of mirror volume data according to an embodiment of the present invention. The method comprises the following steps:
s110: receiving a cloud-up request corresponding to the mirror image volume;
it should be noted that, a source volume is mirrored at a certain time to generate a mirror volume corresponding to the source volume, and data in the mirror volume is the same as data in the source volume at that time. The user can initiate a cloud-up request of the mirror volume, that is, the cloud-up request of the mirror volume input by the user can be accepted.
S120: performing snapshot operation on the mirror image volume at the current moment to obtain a snapshot volume corresponding to the mirror image volume;
specifically, after receiving a cloud request of the mirror volume, a snapshot is established for the mirror volume at the current moment, and a snapshot volume corresponding to the mirror volume at the moment is obtained. The snapshot volume can record the data state in the mirror volume, that is, can record the state information of each data address in the mirror volume. The current time refers to the time when the cloud-up request of the mirror volume is received.
S130: and uploading data corresponding to the current moment in the mirror image volume to the cloud according to the mirror image volume and the snapshot volume.
It can be understood that when uploading data in the mirror image volume to the cloud, as new data may be written in the source volume in the process of uploading the data of the mirror image volume to the cloud, when new data is written in the source volume, the data in the source volume may be synchronized to the mirror image volume, and at this time, the data in the mirror image volume may change, so that when uploading the data in the mirror image volume to the cloud again in the application, the data corresponding to the current time in the mirror image volume is uploaded to the cloud by combining the mirror image volume and the snapshot volume. The data which are not changed in the mirror image volume in the uploading process are directly uploaded to the cloud end from the mirror image volume, and for the changed data, the original data corresponding to the changed data are obtained from the snapshot volume and uploaded to the cloud end, so that the consistency of the cloud data in the mirror image volume is guaranteed.
Specifically, the process of uploading the data corresponding to the current time in the mirror image volume to the cloud end according to the mirror image volume and the snapshot volume in S130 may specifically include:
acquiring bitmap information corresponding to the mirror image volume at the current moment according to the snapshot volume, wherein the bitmap information comprises state information of each data address in the mirror image volume;
specifically, after the snapshot volume is established for the mirror volume, the snapshot volume records bitmap information in the mirror volume, that is, state information of each data address in the mirror volume, so that the state information of each data address corresponding to the mirror volume at the current time can be obtained according to the snapshot volume.
Judging whether the state information of each data address changes or not, and determining each first data address with changed state information and each second data address with unchanged state information;
specifically, after data corresponding to a certain data address in the mirror volume is rewritten, the state information of the data address changes, so whether the data corresponding to each data address is rewritten or not can be determined according to the state information of each data address.
Acquiring first data corresponding to each first data address from the snapshot volume according to each first data address, and uploading each first data to a cloud end;
and acquiring second data corresponding to each second data address from the mirror image volume according to each second data address, and uploading each second data to the cloud.
It can be understood that when new data is written in the source volume, the data is copied to a corresponding data address in the mirror volume, and since original data in the mirror volume is copied to the snapshot volume through snapshot operation, corresponding original data (i.e., first data) can be obtained from the snapshot volume according to the first data address where the state information changes, and the first data is uploaded to the cloud; and corresponding second data can be acquired from the mirror volume according to the second data address without the change of the state information, and are uploaded to the cloud.
Specifically, after the snapshot is established on the mirror image volume, the data in the mirror image volume can be transmitted to the cloud, whether the data in the data address changes or not is judged according to the state information of the corresponding data address in the transmission process, when the data changes, the original data corresponding to the data address is obtained from the snapshot volume, the original data is uploaded to the cloud, then whether the state information corresponding to the next data address changes or not is judged continuously, and when the data does not change, the data corresponding to the data address is obtained from the mirror image volume and is uploaded to the cloud.
For example, referring to fig. 2, at time T1, a mirroring operation is performed on a source volume to obtain a mirror volume corresponding to the source volume; at a time T2, a user sends a cloud loading request of a mirror image volume, and after receiving the cloud loading request of the mirror image volume, a snapshot is established on the mirror image volume to obtain a corresponding snapshot volume, and data transmission to a cloud is started, and at this time, data a is ready to be written into a source volume; at time T3, data a is written to the source volume, and at this time, the data in the mirror volume continues to appear in the cloud; at the time of T4, the data a is ready to be copied from the source volume to the mirror volume, where the data in the mirror volume is continuously in the cloud, and at the time of T5, the data a is copied to the mirror volume, so that the state information of the data address written in the data a on the mirror volume is changed, and the original data originally written in the data address on the mirror volume has been copied to the snapshot volume through snapshot operation, and at this time, the original data in the data address is not yet in the cloud, so that the original data corresponding to the data address is obtained from the snapshot volume and uploaded to the cloud; at the time T6, since the state information of the remaining data addresses in the mirror volume is not changed, the remaining data is directly acquired from the mirror volume and uploaded to the cloud, so that the cloud of the mirror volume data is realized.
Further, the method further comprises:
and deleting the snapshot volume after the data corresponding to the current moment in the mirror volume is uploaded successfully.
It should be noted that, after the data in the mirror volume is successfully clouded, in order to avoid the memory occupied by the established snapshot volume and the corresponding bitmap information, the snapshot volume may be deleted in the present application.
Furthermore, in order to facilitate the user to timely know that the data in the mirror volume is successfully clouded, the method further includes:
and after the data corresponding to the current moment in the mirror image volume is successfully uploaded, feeding back prompt information of successful uploading to the user.
The prompt information can be text information, sound information or prompt lamp information, and can be specifically set according to actual needs. It should be further noted that, in S110 in the present application, the process of receiving the cloud request corresponding to the mirror volume is as follows: and receiving a cloud-up request corresponding to the mirror volume input by a user. Certainly, in practical application, the cloud-up operation may be performed on the data in the mirror volume at regular time, so that the cloud-up request of the mirror volume sent at regular time may also be received.
The embodiment of the invention provides a method for realizing cloud application of mirror volume data, which comprises the following steps: receiving a cloud-up request corresponding to the mirror image volume; performing snapshot operation on the mirror image volume at the current moment to obtain a snapshot volume corresponding to the mirror image volume; and uploading data corresponding to the current moment in the mirror image volume to the cloud according to the mirror image volume and the snapshot volume. Therefore, after a cloud loading request of the mirror image volume is received, the mirror image volume is snapshot to obtain the snapshot volume corresponding to the current moment, and then the data corresponding to the current moment in the mirror image volume is uploaded to the cloud end through the mirror image volume and the snapshot volume, so that the rewriting of the mirror image volume by the data from the source volume does not affect the cloud loading of the data, the consistency of the data before and after cloud loading is ensured, and the cloud loading of the mirror image volume data and the combination of the mirror image and cloud backup are realized.
