Linux® Quick Fix

The Network File System protocol (NFS) is used when disks need to be shared between Linux servers. Basic configuration is fairly simple, and this chapter will explain all the essential steps....

Linux data storage disks contain files stored in filesystems with a standardized directory structure. New disks are added by attaching, or mounting, the directories of their filesystems to a directory of an already existing filesystem. This in effect...

1.3-1 nfs-utils-1.0.1-3.9 [root@bigboy tmp]# A blank list means that you'll have to install the required packages. You also need to have the RPC portmap package installed, and the rpm command can tell you whether it's on your system a...

A small office has an old Linux server that is running out of disk space. The office cannot tolerate any down time, even after hours, because the server is accessed by overseas programmers and clients at night and local ones by day. Budgets are tigh...

Both the NFS server and NFS client have to have parts of the NFS package installed and running. The server needs portmap, nfs, and nfslock operational, as well as a correctly configured /etc/exports file. Here's how to do it. The /etc/exports File...

NFS configuration on the client requires you to start the NFS application; create a directory on which to mount the NFS server's directories that you exported via the /etc/exports file, and finally to mount the NFS server's directory on your local di...

You can force your system to re-read the /etc/exports file by restarting NFS. In a nonproduction environment, this may cause disruptions when an exported directory suddenly disappears without prior notification to users. Here are some methods you can...

NFS client management, therefore, becomes more difficult. Also, the mount is permanent, tying up system resources even when the NFS server isn't being accessed. NFS uses an automounter feature that overcomes these shortcomings by allowing you to byp...

Another common cause of failure is the iptables firewall daemon running on either the server or client without the administrator realizing it. When the client and server are on different networks, these checks still apply, but you'll also have to ma...

NFS can be temperamental. An incorrect configuration can cause it to be unresponsive. Its security is relatively weak, and you have to be aware of the file permissions on both the NFS client and server to get it to work correctly. Often these issues ...

As you have seen NFS can be a very powerful tool in providing clients with access to large amounts of data, such as a database stored on a centralized server. Many of the new network-attached storage products currently available on the market rely on...
