Metadata processing method and device, processing system and storage medium

By storing the metadata table to nonvolatile memory when the hard disk is powered off and dividing it into multiple sub-tables, and calling multiple processing threads to restore the sub-tables in parallel when the hard disk is powered on, the problem of slow recovery speed of L2P metadata table when the hard disk is powered on is solved, and faster power-on recovery speed and disk recognition speed are achieved.

Abstract

The invention provides a metadata processing method and device, a metadata processing system and a storage medium, and relates to the technical field of data storage, the metadata processing method comprises the following steps: under the condition that storage equipment is powered off, storing a metadata table in a volatile memory into a nonvolatile memory, the volatile memory and the nonvolatile memory are arranged in the storage device, the metadata table is divided into N sub-tables, and the N sub-tables are respectively stored in a plurality of logic operation units of the nonvolatile memory; under the condition that the storage device is powered on, N processing threads are called for the N sub-tables to execute N recovery operations in parallel, so that the N sub-tables are synchronously recovered from the nonvolatile memory to the volatile memory.
