Your responsibilities as an NFS administrator depend on your site's requirements and your role as a network administrator. If you are responsible for all the systems on your local network, you might be responsible for determining the following:
Which systems can serve as dedicated servers
Which systems can serve as both servers and clients
Which systems serve as clients only
Maintaining a server after it has been set up involves the following tasks:
Sharing and unsharing file systems as necessary
Modifying administrative files to update the lists of file systems your system mounts automatically
Checking the status of the network
Diagnosing and fixing NFS-related problems as they arise
Setting up maps for autofs
A system can be both a server and a client. So, a system can be used to share local file systems with remote systems and to mount remote file systems.
