AutoFS in Linux

AutoFS automounts desired nfs share and other mountpoints automatically, when it is needed.

# yum install autofs
# /etc/init.d/autofs start
# chkconfig autofs on

Open the /etc/auto.master file to make your new entries for the automount. You will have one example in the file as cdrom.

# vim /etc/auto.master

/remote    /etc/auto.remote
:wq

Now create auto.remote file in the /etc/ directory

# vim /etc/auto.remote
nfs        -fstype=nfs,intr         192.168.122.50:/home/share
:wq

# /etc/init.d/autofs restart

# cd /remote/nfs
or
# ls /remote/nfs/

Now you should be able to access to the nfs from automount, if it becomes inactive for about 10 minutes, it will be disconnected automatically until you again access it.
