The problem I observe happens with FreeBSD 6.4-R and 7.0-R with nfsv3. The fstab entry I use is:

server:/Volume /local/dir nfs bg,rw,intr,-T,-r32768,-w16384 0 0

The server runs on Mac OSX 10.5.

In the meantime, I had the chance to examine a failure a little bit closer. As far as I can see in the moment a file modified on a Linux NFS client gets a new modification time on the NFS server but the FreeBSD client still sees the old timestamp. This obviously happens sporadically only under some circumstances I do not know further. I'll do some further testing the next days.

Could you imagine a kind of directory or metadata caching on FreeBSD NFS clients that may cause this behaviour?

I forgot to mention one detail: File modification happens with emacs; thus the modified file is indeed a new one with a new inode number whereas the old version keeps its inode and gets renamed.

Best regards
