If a remote replication pair is in the split state and a node in a cluster cannot provide services (for example, a node is restarted during the cluster upgrade), the remote replication configuration information of some directories may be collected on the disk but not written to the corresponding directory. As a result, an abnormal interruption is reported during data synchronization of the remote replication pair. This problem will be resolved in V300R006C20SPC300.
Temporary solution：
Solution 1: Perform full synchronization for the directory where the synchronization was interrupted.
Solution 2: Restore the configuration information of the corresponding directory and restart the data synchronization.
