User-space NFSv3 Server
UNFS3 is a user-space implementation of the NFSv3 server specification.
It provides a daemon for the MOUNT and NFS protocols, which are used
by NFS clients for accessing files on the server.
The goals of the UNFS3 project are, in order of importance:
- Correctness: it should implement the semantics of NFSv3 as
closely as possible. It should also detect races with local file system
activity on the server.
- Portability: it should run on any Unix-like operating system.
So far, it is known to work on Linux and SunOS/Solaris.
- Completeness: it should support all aspects of the NFSv3
specification, within the limits possible from user-space.
- Performance: it should be as fast as possible. It is impossible
to outmatch in-kernel NFS servers from user-space, but UNFS3 should
not lag too far behind.
So far, UNFS3 passes the basic and general tests of the
Connectathon 2004 NFS testsuite and survives fsx stress testing. The tests
were run on Linux using the in-kernel NFS client.
