nfstest_interop - NFS interoperability tests

nfstest_interop --server <server> [options]

Basic interoperability tests verify that a file written with different versions of NFS is written correctly. The contents of the file are verified by reading the file back using one of the NFS versions.

The tests append different data from different versions of NFS one at a time then reads the contents of the file to verify it was written correctly. This is done twice for each test:


1) Mount different versions of NFS (NFSv3, NFSv4, NFSv4.1)
2) Create empty file
3) Append data using NFSv3
4) Append data using NFSv4
5) Append data using NFSv4.1
6) Read file and verify contents are correct
7) Append data using NFSv3
8) Append data using NFSv4
9) Append data using NFSv4.1
10) Read file and verify contents are correct
