Abstract
Techniques for storing metadata involve: storing first metadata associated with a system operation in a volatile memory of a storage system while the storage system is in a startup stage. The storage system does not perform read/write requests of a client during the startup stage. Such techniques further involve: suspending the system operation of the storage system during the startup stage in response to determining that the intermediate persistent storage device has failed. Such techniques further involve: storing the first metadata in the volatile memory into the persistent storage device. Such techniques further involve: storing the first metadata into the intermediate persistent storage device in response to determining that the intermediate persistent storage device is available again. Accordingly, the risk of losing metadata when the storage device is powered down can be reduced.
