Applies to

  • ONTAP 9
  • CIFS (oplocks enabled)
  • NFSv4
  • ETL or other rapid file turnover workflow (create, write, read, delete between multiple clients)
  • (Possible) SQL statements written into short-lived file for import into DBMS

Issue

  • NFS (v4) client attempts to delete a file by issuing a REMOVE call, but receives NFS4ERR_FILE_OPEN
  • Workflow characteristics:
    • An NFS client creates and writes a file for import by a CIFS client (SQL Server is a known example)
      • SQL Server imports are one known example - other scripted / coordinated actions between NFS and CIFS clients on the same, short-lived file could exhibit the same behavior
    • Oplocks enabled on the CIFS share from which the CIFS client is importing data
    • CIFS client fully reads the import file, but does not close the file proactively, preventing the NFS writer from deleting it until the oplocks held by the CIFS client expire
