Description of problem:

I have 2 NFS clients mounting the same export from a RHEL4.8 box. When looking on the client, 2 files with the same name, same inode are present in the same directory. One client is a RHEL4 host the other is a RHEL5 host.

However when viewing on the server, only one file is present in the directory.

How reproducible:

This NFS server sees tens of thousands of files passing through it daily. This is now the second time this issue has presented itself.

In order to fix it, the file has to be deleted and skipped. The file can be removed from either the client or the server.
