Provided is a method for managing data in an asymmetric cluster file system to make a metadata server effectively control a data server, and therethrough, to configure or reconfigure a device and a file layout in a state of taking measure against a failure of the data server or adding a data server after copying data. The provided method for managing the data in the asymmetric cluster file system, if receiving a request for opening a file not existing at the data servers, generates a file at the data server by allocating a file handle value and a file name, copies the file generated or stored at the data server based on a preset copy level, and performs a process for the files stored at the data servers.
