Sample Map Hierarchy
In the following example, an organization consisting of many departments, wants to organize a
shared automounted directory structure. The shared top-level directory is called /org. The /org
directory contains several subdirectories, which are listed in the auto_org map. Each department
administers its own map for its subdirectory.
The AutoFS master map needs only a single entry for /org as in the following example:
# auto_master map
# Directory Map Name
/org auto_org
The auto_org map appears similar to the following:
finance -fstype=autofs auto_finance
marketing -fstype=autofs auto_marketing
legal -fstype=autofs auto_legal
research -fstype=autofs auto_research
eng -fstype=autofs auto_eng
The engineering department map, auto_eng, appears similar to the following:
releases bigiron:/export/releases
tools mickey,minnie:/export/tools
source -fstype=autofs auto_eng_source
projects -fstype=autofs auto_eng_projects
A user in the blackhole project within engineering can use the following path:
/org/eng/projects/blackhole
Starting with the AutoFS mount at /org, the evaluation of this path dynamically creates additional
AutoFS mounts at /org/eng and /org/eng/projects. No action is required for the changes
to take effect on the user's system because the AutoFS mounts are created only when required.
You need to run the automount command only when you make changes to the master map or
to a direct map.
Modifying or Removing an Automounted Directory from a Map
To modify or remove an automounted directory from a map, follow these steps:
1. Enter the following command to determine whether the directory is currently in use:
/usr/sbin/fuser -cu local_mount_point
This command lists the process IDs and user names of everyone using the mounted directory.
2. Warn all users to exit the directory. Terminate processes that are using the directory, or wait
until the processes terminate. Enter the following command to kill all the processes that are
using the mounted directory:
/usr/sbin/fuser -ck local_mount_point
3. Use an editor to modify the direct or indirect map.
4. If you removed all the entries in the direct or indirect map, remove that map’s entry in the
master map.
5. If you made any changes to the master map, or if you added or modified a local mount-point
in a direct map, enter the following command to force AutoFS to reread its maps:
