A method and system for providing multi-node file system access to files on a single-node storage stack. The method may include sending a data access request from a client system to a server system over a network. The data access request may comprise a request to access data which is stored on one or more storage devices whose access is controlled by the server system. The method may include using a mapping interface to determine a quantity of components in the storage stack. The method may further include using the mapping interface to communicate with the storage stack components to retrieve a physical location of the data on the storage devices and sending the physical location of the data to the client. The method may include the client bypassing the server to access the data on the storage devices at the physical location provided by the mapping interface.
