Setting Up NFS Service
Use Server Admin to change NFS service settings. The following sections describe the
tasks for conguring and starting NFS service.
Conguring NFS Service Settings
NFS service settings enable you to set the maximum number of daemons and choose
how you want to serve clients—using TCP, UDP, or both.
To congure NFS service settings:
1 Open Server Admin and connect to the server.
2 Click the triangle at the left of the server.
The list of services appears.
3 From the expanded Servers list, select NFS.
4 Click Settings.
5 In the “Use__server threads” eld, enter the maximum number of NFS threads you
want to run at one time.
An NFS thread is a thread running inside the nfsd process. It continuously runs behind
the scenes and processes read and write requests from clients. The more threads that
are available, the more concurrent clients can be served.
6 Select how you want to serve data to your client computers.
TCP separates data into packets (small bits of data sent over the network using IP) and
uses error correction to make sure information is transmitted properly.
UDP is a correctionless and connectionless transport protocol. UDP doesn’t break
data into packets, so it uses fewer system resources. It’s more scalable than TCP and is
a good choice for a heavily used server because it puts a smaller load on the server.
However, do not use UDP if remote clients are using the service.
TCP provides better performance for clients than UDP. However, unless you have a
specic performance concern, select both TCP and UDP.
7 Click Save.
From the command line:
You can view or congure NFS service settings using the serveradmin command. You
can congure the number of daemons you want to run at one time and whether you
want to use TCP or UDP.
To view a setting: m
$ sudo serveradmin settings nfs:setting
To view all settings: m
$ sudo serveradmin settings nfs
To change NFS service settings: m
