Provided that I have write permission to the directory I touch, I can do the following for getting a stale file handle: > touch .. > ls ls: cannot open directory .: Stale NFS file handle This makes the filesystem quite unusable, as anything which touches a directory above (like writing a file) can stop an application. If I leave the directory and cd into it again, it content is listable. >From our computing center that the server runs I got the information that it is NetApp ONTAP 7.3.6P4. I observed the problem here with openSUSE-11.4 (kernel: 2.6.37.6-0.20-desktop), openSUSE-12.1 (kernel: 3.4.4-1-desktop), openSUSE-12.2 (kernel: 3.4.6-2.10-desktop) and all x86_64 architecture but _not_ with openSUSE-11.3 (kernel: 2.6.34.10-0.6-desktop). We use NFSv4 without encryption and userdata from NIS. I'm looking for suggestions to resolve this problem.
