1. A computer-implemented method of simulating client-side file system referral capability, comprising:

  • receiving, at a first file system server from a legacy client, a request for a file system, wherein the legacy client does not support referral file access protocol;

    determining, by the first file system server, that the requested file system is not stored at the first file system server but that the first file system server instead stores a referral for the requested file system, the referral comprising a key value uniquely associated with the requested file system;

    creating, by the first file system server responsive to the determining, a symbolic reference for the requested file system, the symbolic reference comprising the key value and a predetermined text string that signifies presence of the symbolic reference; and

    returning, from the first file system server to the legacy client as a response to the request, the symbolic reference instead of the requested file system, wherein presence of the predetermined text string in a path name component provided in the response thereby signals that client-side resolution is needed, the client-side resolution comprising accessing a client-side mapping that uniquely associates the key value with location information that identifies a location of the requested file system on a second file system server that is distinct from the first file system server.
