13. Error Values

NFS error numbers are assigned to failed operations within a COMPOUND or CB_COMPOUND request. A COMPOUND request contains a number of NFS operations that have their results encoded in sequence in a COMPOUND reply. The results of successful operations will consist of an NFS4_OK status followed by the encoded results of the operation. If an NFS operation fails, an error status will be entered in the reply, and the COMPOUND request will be terminated.

                    Table 6: Protocol Error Definitions

13.1.1. General Errors

This section deals with errors that are applicable to a broad set of different purposes.
13.1.1.1. NFS4ERR_BADXDR (Error Code 10036)
The arguments for this operation do not match those specified in the XDR definition. This includes situations in which the request ends before all the arguments have been seen. Note that this error applies when fixed enumerations (these include booleans) have a value within the input stream that is not valid for the enum. A replier may pre-parse all operations for a COMPOUND procedure before doing any operation execution and return RPC-level XDR errors in that case.
13.1.1.2. NFS4ERR_BAD_COOKIE (Error Code 10003)
This error is used for operations that provide a set of information indexed by some quantity provided by the client or cookie sent by the server for an earlier invocation. Where the value cannot be used for its intended purpose, this error results.
Top   ToC   RFC7530 - Page 181
13.1.1.3. NFS4ERR_DELAY (Error Code 10008)
For any of a number of reasons, the replier could not process this operation in what was deemed a reasonable time. The client should wait and then try the request with a new RPC transaction ID. The following are two examples of what might lead to this situation: o A server that supports hierarchical storage receives a request to process a file that had been migrated. o An operation requires a delegation recall to proceed, and waiting for this delegation recall makes processing this request in a timely fashion impossible.
13.1.1.4. NFS4ERR_INVAL (Error Code 22)
The arguments for this operation are not valid for some reason, even though they do match those specified in the XDR definition for the request.
13.1.1.5. NFS4ERR_NOTSUPP (Error Code 10004)
The operation is not supported, either because the operation is an OPTIONAL one and is not supported by this server or because the operation MUST NOT be implemented in the current minor version.
13.1.1.6. NFS4ERR_SERVERFAULT (Error Code 10006)
An error that does not map to any of the specific legal NFSv4 protocol error values occurred on the server. The client should translate this into an appropriate error. UNIX clients may choose to translate this to EIO.
13.1.1.7. NFS4ERR_TOOSMALL (Error Code 10005)
This error is used where an operation returns a variable amount of data, with a limit specified by the client. Where the data returned cannot be fitted within the limit specified by the client, this error results.

13.1.2. Filehandle Errors

These errors deal with the situation in which the current or saved filehandle, or the filehandle passed to PUTFH intended to become the current filehandle, is invalid in some way. This includes situations in which the filehandle is a valid filehandle in general but is not of the appropriate object type for the current operation.
Top   ToC   RFC7530 - Page 182
   Where the error description indicates a problem with the current or
   saved filehandle, it is to be understood that filehandles are only
   checked for the condition if they are implicit arguments of the
   operation in question.

13.1.2.1. NFS4ERR_BADHANDLE (Error Code 10001)
This error is generated for an illegal NFS filehandle for the current server. The current filehandle failed internal consistency checks. Once accepted as valid (by PUTFH), no subsequent status change can cause the filehandle to generate this error.
13.1.2.2. NFS4ERR_FHEXPIRED (Error Code 10014)
A current or saved filehandle that is an argument to the current operation is volatile and has expired at the server.
13.1.2.3. NFS4ERR_ISDIR (Error Code 21)
The current or saved filehandle designates a directory when the current operation does not allow a directory to be accepted as the target of this operation.
13.1.2.4. NFS4ERR_MOVED (Error Code 10019)
The file system that contains the current filehandle object is not present at the server. It may have been relocated or migrated to another server, or may have never been present. The client may obtain the new file system location by obtaining the "fs_locations" attribute for the current filehandle. For further discussion, refer to Section 8.
13.1.2.5. NFS4ERR_NOFILEHANDLE (Error Code 10020)
The logical current or saved filehandle value is required by the current operation and is not set. This may be a result of a malformed COMPOUND operation (i.e., no PUTFH or PUTROOTFH before an operation that requires that the current filehandle be set).
13.1.2.6. NFS4ERR_NOTDIR (Error Code 20)
The current (or saved) filehandle designates an object that is not a directory for an operation in which a directory is required.
Top   ToC   RFC7530 - Page 183
13.1.2.7. NFS4ERR_STALE (Error Code 70)
The current or saved filehandle value designating an argument to the current operation is invalid. The file system object referred to by that filehandle no longer exists, or access to it has been revoked.
13.1.2.8. NFS4ERR_SYMLINK (Error Code 10029)
The current filehandle designates a symbolic link when the current operation does not allow a symbolic link as the target.

13.1.3. Compound Structure Errors

This section deals with errors that relate to the overall structure of a COMPOUND request (by which we mean to include both COMPOUND and CB_COMPOUND), rather than to particular operations. There are a number of basic constraints on the operations that may appear in a COMPOUND request.
13.1.3.1. NFS_OK (Error Code 0)
NFS_OK indicates that the operation completed successfully, in that all of the constituent operations completed without error.
13.1.3.2. NFS4ERR_MINOR_VERS_MISMATCH (Error Code 10021)
The minor version specified is not one that the current listener supports. This value is returned in the overall status for the COMPOUND procedure but is not associated with a specific operation, since the results must specify a result count of zero.
13.1.3.3. NFS4ERR_OP_ILLEGAL (Error Code 10044)
The operation code is not a valid one for the current COMPOUND procedure. The opcode in the result stream matched with this error is the ILLEGAL value, although the value that appears in the request stream may be different. Where an illegal value appears and the replier pre-parses all operations for a COMPOUND procedure before doing any operation execution, an RPC-level XDR error may be returned in this case.
Top   ToC   RFC7530 - Page 184
13.1.3.4. NFS4ERR_RESOURCE (Error Code 10018)
For the processing of the COMPOUND procedure, the server may exhaust available resources and cannot continue processing operations within the COMPOUND procedure. This error will be returned from the server in those instances of resource exhaustion related to the processing of the COMPOUND procedure.

13.1.4. File System Errors

These errors describe situations that occurred in the underlying file system implementation rather than in the protocol or any NFSv4.x feature.
13.1.4.1. NFS4ERR_BADTYPE (Error Code 10007)
An attempt was made to create an object with an inappropriate type specified to CREATE. This may be because the type is undefined; because it is a type not supported by the server; or because it is a type for which create is not intended, such as a regular file or named attribute, for which OPEN is used to do the file creation.
13.1.4.2. NFS4ERR_DQUOT (Error Code 69)
The resource (quota) hard limit has been exceeded. The user's resource limit on the server has been exceeded.
13.1.4.3. NFS4ERR_EXIST (Error Code 17)
A file system object of the specified target name (when creating, renaming, or linking) already exists.
13.1.4.4. NFS4ERR_FBIG (Error Code 27)
The file system object is too large. The operation would have caused a file system object to grow beyond the server's limit.
13.1.4.5. NFS4ERR_FILE_OPEN (Error Code 10046)
The operation is not allowed because a file system object involved in the operation is currently open. Servers may, but are not required to, disallow linking to, removing, or renaming open file system objects.
13.1.4.6. NFS4ERR_IO (Error Code 5)
This indicates that an I/O error occurred for which the file system was unable to provide recovery.
Top   ToC   RFC7530 - Page 185
13.1.4.7. NFS4ERR_MLINK (Error Code 31)
The request would have caused the server's limit for the number of hard links a file system object may have to be exceeded.
13.1.4.8. NFS4ERR_NOENT (Error Code 2)
This indicates no such file or directory. The file system object referenced by the name specified does not exist.
13.1.4.9. NFS4ERR_NOSPC (Error Code 28)
This indicates no space left on the device. The operation would have caused the server's file system to exceed its limit.
13.1.4.10. NFS4ERR_NOTEMPTY (Error Code 66)
An attempt was made to remove a directory that was not empty.
13.1.4.11. NFS4ERR_NXIO (Error Code 6)
This indicates an I/O error. There is no such device or address.
13.1.4.12. NFS4ERR_RESTOREFH (Error Code 10030)
The RESTOREFH operation does not have a saved filehandle (identified by SAVEFH) to operate upon.
13.1.4.13. NFS4ERR_ROFS (Error Code 30)
This indicates a read-only file system. A modifying operation was attempted on a read-only file system.
13.1.4.14. NFS4ERR_XDEV (Error Code 18)
This indicates an attempt to do an operation, such as linking, that inappropriately crosses a boundary. For example, this may be due to a boundary between: o File systems (where the fsids are different). o Different named attribute directories, or between a named attribute directory and an ordinary directory. o Regions of a file system that the file system implementation treats as separate (for example, for space accounting purposes), and where cross-connection between the regions is not allowed.
Top   ToC   RFC7530 - Page 186

13.1.5. State Management Errors

These errors indicate problems with the stateid (or one of the stateids) passed to a given operation. This includes situations in which the stateid is invalid, as well as situations in which the stateid is valid but designates revoked locking state. Depending on the operation, the stateid, when valid, may designate opens, byte-range locks, or file delegations.
13.1.5.1. NFS4ERR_ADMIN_REVOKED (Error Code 10047)
A stateid designates locking state of any type that has been revoked due to administrative interaction, possibly while the lease is valid, or because a delegation was revoked because of failure to return it, while the lease was valid.
13.1.5.2. NFS4ERR_BAD_STATEID (Error Code 10025)
A stateid generated by the current server instance was used that either: o Does not designate any locking state (either current or superseded) for a current (state-owner, file) pair. o Designates locking state that was freed after lease expiration but without any lease cancellation, as may happen in the handling of "courtesy locks".
13.1.5.3. NFS4ERR_EXPIRED (Error Code 10011)
A stateid or clientid designates locking state of any type that has been revoked or released due to cancellation of the client's lease, either immediately upon lease expiration, or following a later request for a conflicting lock.
13.1.5.4. NFS4ERR_LEASE_MOVED (Error Code 10031)
A lease being renewed is associated with a file system that has been migrated to a new server.
13.1.5.5. NFS4ERR_OLD_STATEID (Error Code 10024)
A stateid is provided with a seqid value that is not the most current.
13.1.5.6. NFS4ERR_STALE_STATEID (Error Code 10023)
A stateid generated by an earlier server instance was used.
Top   ToC   RFC7530 - Page 187

13.1.6. Security Errors

These are the various permission-related errors in NFSv4.
13.1.6.1. NFS4ERR_ACCESS (Error Code 13)
This indicates permission denied. The caller does not have the correct permission to perform the requested operation. Contrast this with NFS4ERR_PERM (Section 13.1.6.2), which restricts itself to owner or privileged user permission failures.
13.1.6.2. NFS4ERR_PERM (Error Code 1)
This indicates that the requester is not the owner. The operation was not allowed because the caller is neither a privileged user (root) nor the owner of the target of the operation.
13.1.6.3. NFS4ERR_WRONGSEC (Error Code 10016)
This indicates that the security mechanism being used by the client for the operation does not match the server's security policy. The client should change the security mechanism being used and re-send the operation. SECINFO can be used to determine the appropriate mechanism.

13.1.7. Name Errors

Names in NFSv4 are UTF-8 strings. When the strings are not of length zero, the error NFS4ERR_INVAL results. When they are not valid UTF-8, the error NFS4ERR_INVAL also results, but servers may accommodate file systems with different character formats and not return this error. Besides this, there are a number of other errors to indicate specific problems with names.
13.1.7.1. NFS4ERR_BADCHAR (Error Code 10040)
A UTF-8 string contains a character that is not supported by the server in the context in which it is being used.
13.1.7.2. NFS4ERR_BADNAME (Error Code 10041)
A name string in a request consisted of valid UTF-8 characters supported by the server, but the name is not supported by the server as a valid name for current operation. An example might be creating a file or directory named ".." on a server whose file system uses that name for links to parent directories.
Top   ToC   RFC7530 - Page 188
   This error should not be returned due to a normalization issue in a
   string.  When a file system keeps names in a particular normalization
   form, it is the server's responsibility to do the appropriate
   normalization, rather than rejecting the name.

13.1.7.3. NFS4ERR_NAMETOOLONG (Error Code 63)
This is returned when the filename in an operation exceeds the server's implementation limit.

13.1.8. Locking Errors

This section deals with errors related to locking -- both share reservations and byte-range locking. It does not deal with errors specific to the process of reclaiming locks. Those are dealt with in the next section.
13.1.8.1. NFS4ERR_BAD_RANGE (Error Code 10042)
The range for a LOCK, LOCKT, or LOCKU operation is not appropriate to the allowable range of offsets for the server. For example, this error results when a server that only supports 32-bit ranges receives a range that cannot be handled by that server. (See Section 16.10.4.)
13.1.8.2. NFS4ERR_BAD_SEQID (Error Code 10026)
The sequence number (seqid) in a locking request is neither the next expected number nor the last number processed.
13.1.8.3. NFS4ERR_DEADLOCK (Error Code 10045)
The server has been able to determine a file locking deadlock condition for a blocking lock request.
13.1.8.4. NFS4ERR_DENIED (Error Code 10010)
An attempt to lock a file is denied. Since this may be a temporary condition, the client is encouraged to re-send the lock request until the lock is accepted. See Section 9.4 for a discussion of the re-send.
Top   ToC   RFC7530 - Page 189
13.1.8.5. NFS4ERR_LOCKED (Error Code 10012)
A READ or WRITE operation was attempted on a file where there was a conflict between the I/O and an existing lock: o There is a share reservation inconsistent with the I/O being done. o The range to be read or written intersects an existing mandatory byte-range lock.
13.1.8.6. NFS4ERR_LOCKS_HELD (Error Code 10037)
An operation was prevented by the unexpected presence of locks.
13.1.8.7. NFS4ERR_LOCK_NOTSUPP (Error Code 10043)
A locking request was attempted that would require the upgrade or downgrade of a lock range already held by the owner when the server does not support atomic upgrade or downgrade of locks.
13.1.8.8. NFS4ERR_LOCK_RANGE (Error Code 10028)
A lock request is operating on a range that partially overlaps a currently held lock for the current lock-owner and does not precisely match a single such lock, where the server does not support this type of request and thus does not implement POSIX locking semantics [fcntl]. See Sections 16.10.5, 16.11.5, and 16.12.5 for a discussion of how this applies to LOCK, LOCKT, and LOCKU, respectively.
13.1.8.9. NFS4ERR_OPENMODE (Error Code 10038)
The client attempted a READ, WRITE, LOCK, or other operation not sanctioned by the stateid passed (e.g., writing to a file opened only for read).
13.1.8.10. NFS4ERR_SHARE_DENIED (Error Code 10015)
An attempt to OPEN a file with a share reservation has failed because of a share conflict.
Top   ToC   RFC7530 - Page 190

13.1.9. Reclaim Errors

These errors relate to the process of reclaiming locks after a server restart.
13.1.9.1. NFS4ERR_GRACE (Error Code 10013)
The server is in its recovery or grace period, which should at least match the lease period of the server. A locking request other than a reclaim could not be granted during that period.
13.1.9.2. NFS4ERR_NO_GRACE (Error Code 10033)
The server cannot guarantee that it has not granted state to another client that may conflict with this client's state. No further reclaims from this client will succeed.
13.1.9.3. NFS4ERR_RECLAIM_BAD (Error Code 10034)
The server cannot guarantee that it has not granted state to another client that may conflict with the requested state. However, this applies only to the state requested in this call; further reclaims may succeed. Unlike NFS4ERR_RECLAIM_CONFLICT, this can occur between correctly functioning clients and servers: the "edge condition" scenarios described in Section 9.6.3.4 leave only the server knowing whether the client's locks are still valid, and NFS4ERR_RECLAIM_BAD is the server's way of informing the client that they are not.
13.1.9.4. NFS4ERR_RECLAIM_CONFLICT (Error Code 10035)
The reclaim attempted by the client conflicts with a lock already held by another client. Unlike NFS4ERR_RECLAIM_BAD, this can only occur if one of the clients misbehaved.
Top   ToC   RFC7530 - Page 191

13.1.10. Client Management Errors

This section deals with errors associated with requests used to create and manage client IDs.
13.1.10.1. NFS4ERR_CLID_INUSE (Error Code 10017)
The SETCLIENTID operation has found that a clientid is already in use by another client.
13.1.10.2. NFS4ERR_STALE_CLIENTID (Error Code 10022)
A client ID not recognized by the server was used in a locking or SETCLIENTID_CONFIRM request.

13.1.11. Attribute Handling Errors

This section deals with errors specific to attribute handling within NFSv4.
13.1.11.1. NFS4ERR_ATTRNOTSUPP (Error Code 10032)
An attribute specified is not supported by the server. This error MUST NOT be returned by the GETATTR operation.
13.1.11.2. NFS4ERR_BADOWNER (Error Code 10039)
This error is returned when an owner or owner_group attribute value or the who field of an ace within an ACL attribute value cannot be translated to a local representation.
13.1.11.3. NFS4ERR_NOT_SAME (Error Code 10027)

13.3. Callback Operations and Their Valid Errors

This section contains a table that gives the valid error returns for each callback operation. The error code NFS4_OK (indicating no error) is not listed but should be understood to be returnable by all callback operations, with the exception of CB_ILLEGAL. +-------------+-----------------------------------------------------+ | Callback | Errors | | Operation | | +-------------+-----------------------------------------------------+ | CB_GETATTR | NFS4ERR_BADHANDLE, NFS4ERR_BADXDR, NFS4ERR_DELAY, | | | NFS4ERR_INVAL, NFS4ERR_SERVERFAULT | | | | | CB_ILLEGAL | NFS4ERR_BADXDR, NFS4ERR_OP_ILLEGAL | | | | | CB_RECALL | NFS4ERR_BADHANDLE, NFS4ERR_BAD_STATEID, | | | NFS4ERR_BADXDR, NFS4ERR_DELAY, NFS4ERR_SERVERFAULT | | | | +-------------+-----------------------------------------------------+ Table 8: Valid Error Returns for Each Protocol Callback Operation
