Applies to

  • ONTAP 9

Answer

The showmount option allows NFS clients can use the showmount -e command to see a list of exports available on an NFS server

Additional Information

  • To enable/disble the showmount option:

vserver nfs modify -vserver <vserver> -showmount {enabled\disabled}

  • In ONTAP 9.6 and later, the paths displayed can be restricted to / only, use the following commands:
    • vserver nfs modify -vserver <vserver> -showmount disabled
    • vserver nfs modify -vserver <vserver> -showmount-root-only enabled
  • After showmount is enabled, clients will be able to query data LIFs for export paths
    • A path is considered "exported" when a junction-path is present and an export-policy defined
    • It is not possible to have a volume junctioned without an export-policy
  • The clientmatch (access from clients, netgroups, and so on) information will not be available
    • Each path will show (everyone) having access in the command output
    • ONTAP cannot list acceptable clientmatches in showmount output
  • NetApp TR-4067
  • Qtrees failing to display in "showmount -e"
  • Can volumes be hidden from the showmount command?
