[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.

Update April 2005: Coda remains active, though this is only clear from looking at the mail list [archives | http://www.coda.cs.cmu.edu/maillists/]. Documentation at the [web site | http://www.coda.cs.cmu.edu/] is out of date, so the mail lists are the current authoritative source of documentation. This may be about to change as several new users have expressed an interest in bringing the documentation up to date.

A former developer of [Coda] started [Intermezzo] as a simpler implementation.
