Preventing data loss during reboot and logical storage resource management device

A logical storage resource management device, comprising:

• a memory on which is stored:
• a reserved memory allocating module to pre-allocate reserved memory for storing a storage resource mapping table;
• a logical storage resource allocating module to allocate logical storage resources to a data source device before a system is rebooted;
• and
• a management module to, when the data source device writes data into the logical storage resources, record, in the storage resource mapping table, a physical location of the logical storage resources into which the data has been written;
• when the system is rebooted, obtain the physical location of the logical storage resources into which the data has been written from the storage resource mapping table, set a state of a physical memory block corresponding to the logical storage resources into which the data has been written as used, and after all data source devices read the data, release the logical storage resources;
• and
• a processor to execute the reserved memory allocating module, the logical storage resource allocating module, and the management module.

A non-transitory computer readable storage medium on which is stored machine readable instructions that when executed by a processor, causes the processor to:

• 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, and recording, 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.
