Stale NFS file handle errors on GuardianOS 5.0

Version 1

    In multi-user NFS environments, client applications may encounter "stale NFS file handle" errors during file I/O, which can sometimes block all I/O from the client until I/O activity ceases and is restarted.


    These error messages may manifest in console or log messages on the client including:


            Stale NFS file handle

            No such file or directory

            Permission denied

            Input/output error


    In some cases, this can be worked around by disabling the subtree_check option on the share's export configuration. In the NFS Access page for a share exhibiting stale NFS file handle behavior, add the option "no_subtree_check" to all export entries.
