Test
Yet another stress test :)
A simple test tool to know the maximum file size on NFSv4.
Conclusion
The maximum file size over NFSv4 on ia32, when server runs XFS is 8Tera bytes. This match to the maximal file size the local file system is able to create (on this architecture).
Software configuration
