Open System Services NFS Management and Operations Guide

Cause
The caller attempted to perform an NFSPROC_ROOT (Get Filesystem Root) or
NFSPROC_WRITECACHE (Write to Cache) call using NFS protocol version 2; both calls are
obsolete in NFS protocol version 2.
Effect
Attempted operation fails.
Recovery
To avoid the error, the caller’s logic must be altered to eliminate all NFSPROC_ROOT and
NFSPROC_WRITECACHE calls. In place of the NFSPROC_ROOT call, use the MNTPROC_MNT
call to look up the root file handle. There is no alternative for the NFSPROC_WRITECACHE call.
If the calls are not eliminated, the caller’s logic must be capable of recovering from the error.
NFS2 Error 63
Name too long. The specified name contains more than the maximum number
of characters allowed.
Cause
This error can occur when any specified name is too long, including pathnames, directory names,
filenames, logical names, netgroup names, group names, and user names.
Effect
Attempted operation fails.
Recovery
Use a shorter name.
NFS2 Error 66
Directory is not empty. The caller attempted to remove a directory from
an NFS file system that was not an empty directory.
Cause
The caller attempted to remove a directory from an NFS fileset that still contained directory
entries. Before it can be removed from a fileset, a directory must be empty; that is, it cannot
contain entries other than “.” (the directory itself) and “..” (the parent directory).
Effect
Attempted operation fails.
Recovery
Remove all entries from the directory (other than “.” and “..”) before attempting to remove the
directory itself.
NFS2 Error 70
Stale fhandle -- The caller specified an invalid file handle (fhandle).
Cause
The caller attempted to perform an operation using an invalid file handle. A file handle can
become invalid when the file it refers to no longer exists or when the access permission has
changed in such a way that access by the caller is revoked. The most common causes are:
• An NFS client left an NFS mount active for a long time and the NFS services were brought
down and back up again during the interval.
• A particular directory was removed so that the caller’s current directory no longer exists.
Effect
Attempted operation fails.
Recovery
Try remounting the server or selecting a different working directory, and then retry the operation.
