A metadata management method and apparatus for a metadata server during a restart period

The invention discloses a metadata management method of a metadata server during a restart period, which comprises the following steps of: sending a network connection request to a client; Modifying afirst preset duration from a first default value to a first trim value, wherein the first trim value is smaller than the first default value; Judging whether a response message of the client has beenreceived after waiting for the first preset time; If not, reading and writing permissions of the client to the metadata are deleted. By reducing the interaction waiting time between the metadata server and the client, the application can accelerate the restart process of the metadata server, accelerate the solution of the management problem of the metadata read and write rights, avoid the long-time blocking of the network, and effectively improve the operation performance of the distributed storage system. The invention also discloses a metadata management device, a device and a computer-readable storage medium of a m
