AUTOFS IN REDHAT LINUX

AUTOFS

Features:

1. Automatically mounts file systems (NFS, local, SMBFS, etc.) upon I/O request
Requirements:

1. autofs-*rpm must be installed

/etc/auto.master - primary configuration file
•- also contains mount points and their mappings

/etc/sysconfig/autofs - default startup directives

Note: AutoFS must be running in order to auto-mount directories

Task:

1. Create an automount for /shares, which will mount /nfs1 & /nfs2

•update /etc/auto.master - '/shares /etc/auto.shares'

•cp /etc/auto.misc /etc/auto.shares

•update the rules in /etc/auto.shares

•Create AutoFS tree: /shares/

•Restart the autofs service

•Unmount: /nfs1 & /nfs2 if necessary

Note: Do NOT auto-mount directories that are already mounted

•Test access to AutoFS controlled directory

•'ls -l /shares/nfs1'

Note: syntax for auto-mount files is as follows:

• []

•nfs1 -fstype=nfs 192.168.75.199:/nfs1
