Applies to

  • ONTAP 9
  • NFS4 ACL
  • Dell Isilon
  • NFSv4.x

Issue

  • In Dell Isilon, folderA has an NFS4 ACE with the f flag, meaning that that files created in folderA are supposed to inherit the ACE
    • ::>nfs4_getfacl folderA
      # file: folderA/
      A:d:OWNER@wax
      A:fd:OWNER@rtncy
  • In Dell Isilon, NFSv4 client can copy file fileA into folder folderA
    • The resulting new file has inherited the desired ACE from folderA and contains the desired contents
  • After migrating folderA to ONTAP, NFSv4 client cannot copy fileA into ONTAP's folderA

    • ::> cp fileA folderA
      cp: failed to close folderA/fileA: Permission denied

    • The new copy of fileA is created, but
      • its ACL is empy
      • its contents are empty
