Hi hce,
You use NFSv3,
the NFSv3's file lock service depend on NLM(Network Lock Manager),
that need a user space program named rpc.statd to support service
like this:
| nfs client | nfs server
-------------------------------------------------
| |
user space | rpc.statd <---> rpc.statd
| ^ | ^
--------------------|------------------------|----
| v | v
kernel | lockd <---> lockd
when your nfs client is a MAC, maybe Mac's user space don't support
a program as rpc.statd, or you don't make the program run correctly.
Maybe you can use NFSv4 to avoid this problem.
