The Coda File System is a descendant of the Andrew File System. Like AFS, Coda offers location-transparent access to a shared Unix file namespace that is mapped on to a collection of dedicated file servers. But Coda represents a substantial improvement over AFS because it offers considerably higher availability in the face of server and network failures. The improvement in availability is achieved using the complementary techniques of server replication and disconnected operation. Disconnected operation proven especially valuable in supporting portable computers. This document is a reference manual for Coda users and system administrators.
