Recovery method for all-flash storage system, and related apparatus

Abstract

The present application relates to the technical field of storage. Disclosed is a method of recovering an all-flash storage system. The method comprises: when metadata of a logical volume has not been modified, marking the state of the metadata of the logical volume as a clean state; after the power to an all-flash storage system is restored, reading the state of the metadata of the logic volume; and if the metadata of the logical volume is in the clean state, restoring the metadata of the logical volume to an accessible state. The method can implement rapid recovery after a power loss failure of an all-flash storage system occurs, thereby shortening the recovery time and improving the availability, reliability and security of the whole storage system.
