Abstract: The embodiments of disclosure disclose a method and device for responding to a request, and a Distributed File System (DFS). The method comprises: receiving from a file access client a request for operating a target file, wherein the request carries a full path of the target file; determining a file identifier and a file location register identifier corresponding to the full path, wherein a file location register corresponding to the file location register identifier isg used for providing location information of a data block of the target file; sending the file identifier and the file location register identifier to the file access client. The embodiments of the disclosure solves the problem that a DFS has a high demand on a file location register hardware, lowers a demand on the file location register hardware, and improves a stability of the system.

Abstract: The disclosure provides a method for identifying a storage device, which includes: obtaining, by a master control server, disk information of a storage device through a storage server; determining, by the master control server, that there is a storage device matching a device identifier according to the disk information, and entering a monitoring state; otherwise, creating a device identifier for the storage device and entering the monitoring state. The disclosure also provides a system for identifying a storage device. Through the method and the system, the storage devices are uniformly identified so as to facilitate unified management of the storage devices.
