Abstract: A computer-implemented method is disclosed. The method starts with determining a first container of a storage system is invalid. The method continues with the storage system setting a data recovery state for the first container to be en-queue, which indicates that data of at least one of the data segments needs to be recovered from the first container, and executing a process to recover any container having an en-queue data recovery state, and for each of the containers, to recover any valid data segment from the corresponding container. The process includes scanning the data segments of the first container to find valid data segments, moving or replicating the valid data segments to a second container, and setting the data recovery state for the first container to be complete once all the valid data segments are moved or replicated to the second container.
