摘要
According to an example, in a method for preventing data loss during reboot, a logical storage resource management device may pre-allocate reserved memory for storing a storage resource mapping table, allocate logical storage resources to a data source device before a system is rebooted, record, in the storage resource mapping table, a physical location of the logical storage resources into which data has been written when the data source device writes the data into the logical storage resources, obtain the physical location of the logical storage resources into which the data has been written from the storage resource mapping table when the system is rebooted, set a state of a physical memory block corresponding to the logical storage resources into which the data has been written as used, and release all logical storage resources after the data source device reads the data.
