When a process has a file open on an NFS share, and the file is removed by another process, an .nfs* file is created. When the original process closes the file, the .nfs* file is removed.
Example:
(system1) $ echo testdata > /NFS_volume/shiznit (system1) $ tail -f /NFS_volume/shiznit (system2) $ rm /NFS_volume/shiznit (system2) $ ls -a .nfs* .nfs00222d9e00000001 (system2) $ cat .nfs00222d9e00000001 testdata (system1) $ Ctrl-C (system1) $ ls -a
