Configuring NFSv4 file and record locking

You can configure NFSv4 file and record locking by specifying the locking lease period and grace period.

  • About NFSv4 file and record locking
    For NFSv4 clients, ONTAP supports the NFSv4 file-locking mechanism, maintaining the state of all file locks under a lease-based model.
  • Specifying the NFSv4 locking lease period
    To specify the NFSv4 locking lease period (that is, the time period in which ONTAP irrevocably grants a lock to a client), you can modify the -v4-lease-seconds option. Shorter lease periods speed up server recovery while longer lease periods are beneficial for servers handling a very large amount of clients.
  • Specifying the NFSv4 locking grace period
    To specify the NFSv4 locking grace period (that is, the time period in which clients attempt to reclaim their locking state from ONTAP during server recovery), you can modify the-v4-grace-seconds option.
