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 NFS servers
Which systems can serve as both NFS servers and NFS clients
Which systems serve as NFS 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 an NFS server and an NFS client. So, a system can be used to share local file systems with remote systems and to mount remote file systems.
