Applies to

  • ONTAP 9
  • NFSv4
  • IBM i (AS/400, IBMi) NFS clients
  • NTFS volumes

Issue

  • Creating files over NFSv4 from an IBMi client to a NetApp ONTAP system, file creation intermittently fails
  • After a period of successful operations, subsequent attempts to create files result in persistent NFS4ERR_BADOWNER errors, even when the client does not send explicit owner or owner_group attributes
  • Example from the Packet Trace :
NFS Call: nfs4_open_create OPENDH: /testAD.txt  
Attrmask: Mode,
Owner, Owner_Group  Owner: user@email.com  
Owner_Group: nobody
NFS Reply: nfs4_open_create OPENStatus: NFS4ERR_BADOWNER
  • Subsequent attempts (without owner/group specified) that work occassionally also fail at some point :
NFS Call: nfs4_open_create OPENDH: /testAD.txt  (no owner/group attributes)
NFS Reply: nfs4_open_create OPENStatus: NFS4ERR_BADOWNER
