Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The double-active storage characteristic means that two storage data centers which are mutually backed up are in an operation state, when one data center fails, the service is automatically switched to the other data center, the problem that the conventional disaster recovery service cannot be automatically switched is solved, and high-level data reliability and service continuity can be provided for users.
A clone volume is a copy of an existing volume, i.e., the data on the source volume is copied to the target volume (clone). Cloning is similar to snapshot in that it is also a copy of one point in time of a volume, with the difference that: a snapshot is the creation of a new snapshot object from a volume, while a clone volume is the creation of a new independent volume, pre-populated with the data of the source volume. When the source volume needs to be rolled back to a certain time point, compared with the snapshot, the source volume needs to be rolled back to the target time point state, the clone volume can be directly used, and the use of the current source volume is not affected. In the scenario where reliability and performance are both required to be high, clone volumes are increasingly used.
Because the dual active storage pool has two storage pools which are simultaneously active, the process of creating the dual active clone volume is complicated, and the current CSI plug-in cannot create the dual active clone volume.
