 2. **Switch from sync to async**: PD regularly checks the heartbeat information of TiKV to judge whether the TiKV node fails or is disconnected. If the number of failed nodes exceeds the number of replicas of the primary data center (`primary-replicas`) and the DR data center (`dr-replicas`), the synchronous replication mode can no longer serve the data replication and it is necessary to switch the status. When the failure or disconnect time exceeds the time set by `wait-store-timeout`, PD switches the status of the cluster to the async mode. Then PD sends the status of async to all TiKV nodes, and the replication mode for TiKV switches from two-center replication to the native Raft majority.
 
-3. **Switch from async to sync**: PD regularly checks the heartbeat information of TiKV to judge whether TiKV nodes are reconnected. If the number of failed nodes is less than the number of replicas of the primary data center (`primary-replicas`) and the DR data center (`dr-replicas`), the synchronous replication mode can be enabled again. PD first switches the status of the cluster to sync-recover and sends the status information to all TiKV nodes. All Regions of TiKV gradually switch to the two-data-center synchronous replication mode and then report the heartbeat information to PD. PD records the status of TiKV Regions and calculates the recovery progress. When all TiKV Regions finish the switching, PD switches the replication mode to sync.
