Problems solved by technology
Therefore, the operation of accidentally deleting a storage space object occurs from time to time, and when the user performs the "delete storage space" operation, the storage system will delete all configurations, metadata, and stored resources related to the storage space object, and the user cannot continue use the storage object
Under normal circumstances, a storage space object will store thousands or even hundreds of millions of files. After deleting the storage space object, all stored data will not be recoverable, resulting in great losses
[0003] Currently, there is no protection against accidental deletion of storage space objects

Embodiments of the present invention provide a method and a device for processing a storage space object. The method comprises: when receiving an instruction of deleting a storage space object, deleting mapping between the storage space object and a host; and recording state information of the storage space object to be in a deleted and not reclaimed state, to reclaim or restore the storage space object. In the embodiments of the present invention, a deleted and not reclaimed state is added to a storage space object, and the storage space object deleted by mistake can be restored when necessary, so that deletion by mistake can be effectively prevented, and loss due to deletion by mistake can be reduced.
Description
technical field [0001] Embodiments of the present invention relate to the field of storage technology, and more specifically, to a method and device for processing storage space objects. Background technique [0002] Small dedicated storage devices generally provide dozens or even hundreds of storage space objects; large storage devices even provide tens of thousands of storage space objects to the outside world. Therefore, the operation of accidentally deleting a storage space object occurs from time to time, and when the user performs the "delete storage space" operation, the storage system will delete all configurations, metadata, and stored resources related to the storage space object, and the user cannot continue Use the storage object. Generally, a storage space object will store thousands or even hundreds of millions of files. After the storage space object is deleted, all the stored data will be irrecoverable, resulting in great loss. [0003] Currently, there is ...
