Abstract

The invention provides a data processing method, system and device in remote replication, and the method comprises the steps of building two simplification pools, respectively building a simplified volume master volume and a simplified volume slave volume in the simplification pools, and building a remote replication relation between the master volume and the slave volume; and when the simplification pool where any simplification volume is located is full, determining that the simplification volume is in a read-only state. According to the invention, when the simplification pool where the simplification volume is located is full, the simplification volume is in the read-only state, and compared with the mode that the volume where the simplification volume is located is set to be in the offline state after a traditional storage pool is full, reading operation of the volume is not affected, and the operation range of services is expanded. And a reaction can be made immediately after thesimplified pool is full, so that the service processing timeliness is not influenced.

Description

technical field [0001] The invention relates to the technical field of remote replication disaster recovery, in particular to a data processing method, system and device in remote replication. Background technique [0002] Remote replication disaster recovery technology stops the remote replication relationship when the storage pool where the primary or secondary volumes are located is full, and the primary and secondary volumes become offline and cannot be read or written. [0003] For the above problems, the existing solution is to expand the storage pool or perform garbage collection on the storage pool after the storage pool is full, so that it is no longer in the pool full state, and only then can the read and write operations be performed on the remote replicated primary volume. [0004] The above-mentioned processing methods are complex and require a lot of cost, and cannot respond immediately after the storage pool is full, which affects the data processing business....
