Description: Volume failover is a critical process in storage system management, especially in distributed environments. This mechanism allows a system to automatically switch to a backup volume in case the primary volume fails or becomes inaccessible. Failover ensures service continuity and minimizes downtime, which is essential for applications requiring high availability. In distributed file systems, this functionality is implemented through data replication across multiple nodes. When a node experiences a failure, the system can redirect data access requests to another node that holds a copy of the data, thus ensuring that users and applications can continue operating without interruptions. This process not only enhances system resilience but also optimizes performance by distributing the workload across multiple volumes. Therefore, volume failover is a fundamental feature for maintaining data integrity and availability in distributed storage environments.
