Display the NFS configurations of Vservers

Availability: This command is available to cluster and Vserver administrators at the admin privilege level.

Description

The vserver nfs show command displays information about NFS-enabled Vservers. The command output depends on the parameter or parameters specified with the command. If no parameters are specified, the command displays the following information about all NFS-enabled Vservers:

  • Vserver name

  • Whether general NFS access is enabled

  • Whether access to NFSv3 clients is enabled

  • Whether access to NFSv4 clients is enabled

  • Whether NFS access over UDP is enabled

  • Whether NFS access over TCP is enabled

  • List of default Windows users (detailed view only)

You can specify additional parameters to display only information that matches those parameters. For instance, to display information only about Vservers that enable access over TCP, enter the command with the -tcp-enable true parameter.
