A method for dynamically adjusting the synchronization rate of storage volume mirroring

Abstract

The invention provides a method for dynamically adjusting the mirror synchronization rate of a storage volume, including: adding a copy volume; judging whether the front end of the system has a first service, when the front end does not have the first service, performing full-speed synchronization, and synchronizing at full-speed After completion, the online time of the second service is detected, and when the online time of the second service is after the full-speed synchronization is completed, full-speed synchronization is performed again to complete the final synchronization; when the front end has the first service, or when the detected second service When the online time of the server is before full-speed synchronization is completed, configure the management server; automatically set different rates during peak and low-peak periods of business; complete synchronization according to different rates. The invention dynamically adjusts the mirror synchronization rate during the peak and low peak periods of the business through real-time performance monitoring, and on the premise of ensuring normal business, quickly completes the mirror synchronization, realizes data protection and migration, and solves the problem of labor-intensive and extremely easy to manually change the synchronization rate. The disadvantages of misuse.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for realizing dynamic adjustment of the mirror synchronization rate of a storage volume. Background technique [0002] Volume mirroring technology is often used in application scenarios such as data protection, data migration, and storage active-active configuration. During the initial volume mirroring synchronization of storage, there are usually front-end services. It is often necessary to ensure the normal operation of front-end services and storage performance. , and it is necessary to complete mirror synchronization as soon as possible to realize data pool storage and ensure data security. At present, the existing technical solutions can only give priority to ensuring the normal operation of the business. During the peak and low-peak hours of the business, the synchronization rate is not changed for the business low-peak period, and the mirror synchronization rate...

Problems solved by technology

The current existing technical solutions generally only give priority to ensuring the normal operation of the business. During the peak and low peak periods of the business, the synchronization rate is not changed during the low peak period of the business, and the mirroring synchronization rate is modified during the peak period of the business. However, In the existing technical solutions, there are two ways to modify the mirror synchronization rate, one is through the GUI, and the other is through the CLI. However, in both methods, manual adjustments are required. However, the volume capacity of the actual production environment They are relatively large, and it often takes several months or even longer to complete the synchronization. If the synchronization rate is adjusted manually throughout the entire process, it will not only require a lot of labor, but it is also extremely easy to cause operational errors, and During this process, if there are on-duty personnel taking turns to monitor continuously, the rate can be manually changed in different business hours, but this will increase labor costs, and the risk of personnel misoperation is also relatively high, especially in production environments. Once misoperation occurs, it will cause immeasurable losses, but if there is no on-duty personnel during this process, you can only set it to a low synchronization rate to ensure normal access to the business, but this will lead to too long a synchronization completion time, and in Before the synchronization is completed, the storage cannot provide data disaster recovery protection. Once a disaster occurs, the data will be completely lost. Therefore, in addition to consuming a lot of labor, it is very easy to cause wrong operations for manually changing the synchronization rate. Therefore, for To solve the disadvantages of manually changing the synchronization rate that consumes a lot of manpower and easily causes erroneous operations, this invention proposes a method for dynamically adjusting the synchronization rate of storage volume mirroring, through real-time monitoring of performance, and dynamically adjusting the synchronization rate during business peak and low peak periods. The mirror synchronization rate realizes the mirror synchronization as fast as possible on the premise of ensuring the normal operation of the business, so as to achieve the purpose of data protection and migration, and does not need to manually adjust the synchronization rate, and also reduces the possibility of erroneous operations
