Zusammenfassung:	A method and system for realizing block storage of a distributed file system, the system comprising: at least one block storage node and a corresponding access node, and a metadata server; setting a corresponding logic unit number (LUN) for the access node, and upon the receipt of a storage data request and the completion of mounting, establishing via the LUN an access connection with a file mapped to the distributed file system; the metadata server maps the LUN to at least one file in the distributed file system, and adds the mapping relationship to metadata information; according to the metadata information, writing the stored data into the block storage node corresponding to the mapping file; and the block storage node is used to store the data into a corresponding storage space. By establishing an LUN corresponding to an access node, mapping the LUN to at least one file in a distributed file system, adding the mapping relationship to metadata information, and updating the metadata during data storage, the
