摘要： A method and device for processing an I/O request in a network file system. The method includes: when a network file system file handle NFS FH in an I/O request cannot be identified, sending, by a network file system server, a request for parsing the unidentifiable NFS FH to a centralized controller (201); receiving, by the network file system server, a file identifier that corresponds to the unidentifiable NFS FH and that is sent by the centralized controller according to the parsing request, where the file identifier is determined according to a prestored correspondence between NFS FHs and file identifiers (202); and processing, by the network file system server, the I/O request according to the file identifier (203). According to the foregoing method and device, perception-free virtual machine migration can be implemented.
