Description: Node recovery refers to the processes involved in restoring a failed node in a distributed storage system, such as a Ceph cluster. When a node in the cluster experiences a failure, it is crucial for the system to recover it to maintain data integrity and availability. This process involves identifying the failed node, reconfiguring the cluster, and reintegrating the node into operation. Node recovery is essential to ensure that the cluster continues to operate without significant interruptions and that the stored data remains accessible. Additionally, distributed storage systems employ data replication and distribution mechanisms that allow other nodes to temporarily take over the functions of the failed node, thereby minimizing the impact on system performance. Node recovery focuses not only on restoring the hardware or software of the node but also on data synchronization and reconfiguring access paths to ensure that the cluster operates optimally after recovery.
