Client cache updates missing? (2.6.31.5)

[Jesper Krogh <jesper-Q2TZfHgGEy4@public.gmane.org>]

Hi.

I'm seeing some random odd behaviour on my NFS clients. It is
not directly reproducible, but I have had users telling me about, but
until you hit stuff like this yourself .. you almost dont believe it.

jk@bach:~$ ssh nfsserver ls -ltrah | grep blast-2.out
-rw-rw-r--   1 jk jk 552K 2009-11-29 09:10 blast-2.out
jk@bach:~$ ls -tlrha  | grep blast-2.out
jk@bach:~$ date
Sun Nov 29 09:17:14 CET 2009
jk@bach:~$ stat blast-2.out
  File: `blast-2.out'
  Size: 564283    	Blocks: 1112       IO Block: 1048576 regular file

So.. the file has been present for 7 minutes on the NFS-server (and any
client doing a fresh mount) but the client I'm sitting on is not having
the file in the directory listing, but if I explicitly ask for it.. its
there.

Wether or not it has anything to do. The file has been written to the
NFS-server from another NFS-client. The server is running 2.6.31.5 and
the client that above was run on is 2.6.24-24 (Ubuntu Jaunty), the
client that wrote the file was running 2.6.29.1.
