Hi,

We've just run into a similar thing. We have an OpenSuSE 10.3 NFS server
exporting a filesystem to about 40 machines, most of which are also
running OpenSuSE 10.3. The client machines are running a distributed
data processing pipeline. The clients create, move and delete directories
and files on the server. We've seen a few instances where the programs on
the clients die with a "no such file or directory" error but no errors in
syslog. Finally last night many of the clients gave these errors in syslog
at about the same time as the client programs died with "no such file or
directory" errors:

I notice that the offending inodes are all the same. This all worked without
problems when the NFS server was SuSE 10.0. The exported filesystem is XFS.

Anyone have any ideas what's going on?
I personally don't, but I have a running thread with some of the NFS maintainers, that I have added this mail to now.
