Abstract
A system for file system data access can include memory devices including a non-volatile memory device, as well as a processing device, operatively coupled with the memory devices to perform operations including receiving a file system (FS) write command and determining whether a write count of a physical super management unit (PSMU) of the non-volatile memory device satisfies a threshold criterion. The operations can include, recording a change of a super management unit (SMU) mapping for FS data of an FS mapping table, where the FS mapping table is a portion of a logical-to-physical (L2P) mapping table and performing a move of SMU data corresponding to the change of the SMU mapping. They can also include creating a backup copy of the FS mapping table on the non-volatile memory device, and restoring the FS mapping table from the backup copy of the FS mapping table.
