Nightmare file system (NFS)

start here:

/etc/fstab

 foohost:/export/data /mnt nfs tcp,rsize=8192,wsize=8192,intr,rw,bg,nosuid,noauto

NFS shares get stale after a while or don't mount at all

This might be caused by the fact that the server really wants to have portnumbers below 1024 for the session. Adding insecure to the exports-file fixes that. Example:

 /home	somehost(rw,insecure)

NFS configuration for central storage

Configuring The NFS Server

Edit the /etc/exports file to allow NFS mounts of the /home directory with read/write access.

 /home                   *(rw,sync,no_subtree_check)

The option listing for each machine will describe what kind of access that machine will have. Important options are:

Let NFS read and make /home available to the network with the exportfs command.

 # exportfs -a

Make sure the required nfs, nfslock, and portmap daemons are running and configured to start after the next reboot.

 # chkconfig nfslock on
 # chkconfig nfs on
 # chkconfig portmap on
 # service portmap start
 # service nfslock start
 # service nfs start

Configuring The NFS Client

Make sure the required netfs, nfslock, and portmap daemons are running and configured to start after the next reboot.

 # chkconfig nfslock on
 # chkconfig netfs on
 # chkconfig portmap on
 # service portmap start
 # service netfs start
 # service nfslock start

Now mount the NFS (server) /home to this client

 # mount server:/home /home/

Configure autofs edit your /etc/auto.master file to refer to file /etc/auto.home for mounting information whenever the /home directory is accessed. After five minutes, autofs unmounts the directory.

 # vi /etc/auto.master
 /home      /etc/auto.home --timeout 600

Edit file /etc/auto.home to do the NFS mount whenever the /home directory is accessed.

 # vi /etc/auto.home
 *   -fstype=nfs,soft,intr,rsize=8192,wsize=8192,nosuid,tcp server:/home/&
