Ok, so, can I conclude that you are therefore saying that ext3 (with default mount options) is compliant with SPEC SFS Run rules wrt NFS protocol requirements:
1. For NFS Version 2, the server adheres to the protocol specification and in particular the requirement that for NFS write operations the NFS server must not reply to the NFS client before any modified file system data or metadata, with the exception of access times, are written to stable storage. 2. For NFS Version 3, the server adheres to the protocol specification. In particular the requirement that for STABLE write requests and COMMIT operations the NFS server must not reply to the NFS client before any modified file system data or metadata, with the exception of access times, are written to stable storage for that specific or related operation. See RFC 1813, NFSv3 protocol specification for a definition of STABLE and COMMIT for NFS write requests. 3. For NFS Version 3, operations which are specified to return wcc data must, in all cases, return TRUE and the correct attribute data. Those operations are:
NFS Version 3 SETATTR READLINK CREATE MKDIR SYMLINK MKNOD REMOVE RMDIR RENAME LINK
4. The server must pass the benchmark validation for the NFS protocol being tested. 5. When UDP is the network transport, UDP checksums must be calculated and verified for all NFS request and reply messages. In other words, checksums must be enabled on both the client and server.
Kind regards Tigran
