Network File System (NFS) is an open IETF standard remote file access protocol. Use the Services NFS screen to enable NFS services on your TrueNAS.

Click CANCEL to exit without saving and return to the Services screen.

Name Description
Number of servers Enter a number to specify how many servers to create. Increase if NFS client responses are slow. Keep this less than or equal to the number of CPUs reported by sysctl -n kern.smp.cpus to limit CPU context switching.
Bind IP Addresses Select IP addresses from dropdown list to listen to for NFS requests. Leave empty for NFS to listen to all available addresses.
Enable NFSv4 Select checkbox to switch from NFSv3 to NFSv4.
NFSv3 ownership model for NFSv4 Select checkbox to provide specific NFSv4 ACL support. This does not require the client and the server to sync users and groups.
Require Kerberos for NFSv4 Select checkbox to force NFS shares to fail if the Kerberos ticket is unavailable.
Serve UDP NFS clients Select checkbox if NFS clients need to use the User Datagram Protocol (UDP).
Allow non-root mount Select checkbox only if required by the NFS client. Select to allow serving non-root mount requests.
Support >16 groups Select checkbox when a user is a member of more than 16 groups. Requires correct configuration of group membership on the NFS server.
Log mountd(8) requests Select checkbox to log mountd syslog requests.
Log rpc.statd(8) and rpc.lockd(8) Select checkbox to log rpc.statd and rpc.lockd syslog requests.
mountd(8) bind port Enter a number to bind mountd only to that port.
rpc.statd(8) bind port Enter a number to bind rpc.statd only to that port.
rpc.lockd(8) bind port Enter a number to bind rpc.lockd only to that port.

The recommendation is to use the default settings for the NFS service. Make changes if there is a need for a specific setting.
