NFS4 Operation Errors
NFS4: Operation Errors
Scan Type: Errors, Severity: High
Column value nfs.opcode: operation number
Column value nfs.nfsstat4: returned result
Network File System (NFS) Version 4 Protocol
https://www.rfc-editor.org/rfc/rfc7530
For the NFSv4 RPC program, there are two traditional RPC procedures: NULL and COMPOUND. All other functionality is defined as a set of operations, and these operations are defined in normal XDR/RPC syntax and semantics. However, these operations are encapsulated within the COMPOUND procedure. This requires that the client combine one or more of the NFSv4 operations into a single request.
NFSv4 Procedures
Procedure 0: NULL - No Operation
Procedure 1: COMPOUND - COMPOUND Operations
NFSv4 Operations
Operation 3: ACCESS - Check Access Rights
Operation 4: CLOSE - Close File
Operation 5: COMMIT - Commit Cached Data
Operation 6: CREATE - Create a Non-regular File Object
Operation 7: DELEGPURGE - Purge Delegations Awaiting Recovery
Operation 8: DELEGRETURN - Return Delegation
Operation 9: GETATTR - Get Attributes
Operation 10: GETFH - Get Current Filehandle
Operation 11: LINK - Create Link to a File
Operation 12: LOCK - Create Lock
Operation 13: LOCKT - Test for Lock
Operation 14: LOCKU - Unlock File
Operation 15: LOOKUP - Look Up Filename
Operation 16: LOOKUPP - Look Up Parent Directory
Operation 17: NVERIFY - Verify Difference in Attributes
Operation 18: OPEN - Open a Regular File
Operation 19: OPENATTR - Open Named Attribute Directory
Operation 20: OPEN_CONFIRM - Confirm Open
Operation 21: OPEN_DOWNGRADE - Reduce Open File Access
Operation 22: PUTFH - Set Current Filehandle
Operation 23: PUTPUBFH - Set Public Filehandle
Operation 24: PUTROOTFH - Set Root Filehandle
Operation 25: READ - Read from File
Operation 26: READDIR - Read Directory
Operation 27: READLINK - Read Symbolic Link
Operation 28: REMOVE - Remove File System Object
Operation 29: RENAME - Rename Directory Entry
Operation 30: RENEW - Renew a Lease
Operation 31: RESTOREFH - Restore Saved Filehandle
Operation 32: SAVEFH - Save Current Filehandle
Operation 33: SECINFO - Obtain Available Security
Operation 34: SETATTR - Set Attributes
Operation 35: SETCLIENTID - Negotiate Client ID
Operation 36: SETCLIENTID_CONFIRM - Confirm Client ID
Operation 37: VERIFY - Verify Same Attributes
Operation 38: WRITE - Write to File
Operation 39: RELEASE_LOCKOWNER - Release Lock-Owner State
Operation 10044: ILLEGAL - Illegal Operation
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.
