[Coda | http://www.coda.cs.cmu.edu/] is an Advanced NetworkFileSystem developed as a research project by the team which wrote [AFS]. [Coda] extends the FileSystem for DisconnectedOperation. Some of [AFS]' developers noticed that caching lets it work quite well for a while in the face of loss of the connection except for issues when writes occur. [Coda] was to allow for scenarios like allowing a laptop with a [WLAN] connection wandering in and out of range to seamlessly synchronize all files (and notify the user of conflicts). The project was quite a success. Coda is supported in [Kernel] 2.6.7 but no longer in active development. It seems to still be maintained, however, as it is not completely dead -- the last release as of July 2004 was v6.0.6 in April. Currently it seems to be the only option for a FileSystem with support for DisconnectedOperation until [OpenAFS] supports this as well. A former developer of [Coda] started [Intermezzo] as a simpler implementation.
