72 Chapter 4 NFS Service
User Datagram Protocol (UDP) is a connection-less transport protocol. UDP doesn’t
break data into packets, so it uses fewer system resources. It’s more scalable than TCP,
and a good choice for a heavily used server. Do not use UDP, however, if remote clients
are using the service.
5 Click Save.
From the Command Line
You can also change the NFS service settings using the serveradmin command in
Terminal. For more information, see the file services chapter of the command-line
administration guide.
Managing NFS Service
This section tells you how to perform day-to-day management tasks for NFS service
once you have it up and running.
Starting and Stopping NFS Service
When the server starts up, a startup script checks to see if any NFS exports are defined;
if so, NFS starts automatically.
If NFS is not running and you add exports, wait a few seconds for the service to launch.
To stop NFS service:
m
Delete all exports.
The nsfd daemons continue to run until the server is restarted.
From the Command Line
You can also stop the NFS service processes using the kill command in Terminal. For
more information, see the file services chapter of the command-line administration
guide.
Viewing NFS Service Status
You use Server Admin to check the status of all Mac OS X Server devices and services.
To view NFS service status:
1 Open Server Admin and select NFS in the Computers & Services list.
2 Click Overview (near the bottom of the window).
The Overview pane tells you whether the service is running, and whether mountd,
nfsd, portmap, rpc.lockd, and rpc.statd processes are running.
The mountd process handles mount requests from client computers (only one mountd
process will appear in the status window if you’ve defined any exports).
The nfsd process responds to read/write requests from client computers that have
mounted folders.
