Abstract
Embodiments of the present disclosure relate to a method, device and computer program product for managing storage systems. A method comprises, in response to receiving a command to recover a storage system, reading first configuration information from a first disk of the storage system to be recovered, the first configuration information indicating a first disk array group to which the first disk belongs. The method further comprises recovering the first disk array group based at least on the first configuration information. The method further comprises, in response to the first disk array group being recovered, reading second configuration information from the first disk array group, the second configuration information indicating a storage resource pool to which the first disk array group belongs. Additionally, the method further comprises recovering the storage resource pool based at least on the second configuration information. Embodiments of the present disclosure can gradually recover various levels of storage objects in the storage system in the event of loss of configuration information in the system database.
