Abstract
A data storage method includes a first client sending a first lock request for locking a first data range of a first file to a metadata server. The metadata server receives the first lock request from the first client. When the first data range of the first file is not locked, the metadata server locks the first data range of the first file and sends a first lock response to the first client to indicate that the first data range of the first file is locked by the first client.
