AutoFS configuration changes
This section describes the various methods to configure your AutoFS environment.
Configuring AutoFS using the nfsconf file
You can use the /etc/rc.config.d/nfsconf file to configure your AutoFS environment. The
/etc/rc.config.d/nfsconf file is the NFS configuration file. This file consists of the following
sets of variables or parameters:
1. Core Configuration Variables
2. Remote Lock Manager Configuration Variables
3. NFS Client and Server Configuration Variables
4. AutoFS Configuration Variables
Table 12 lists the AutoFS configuration variables that you can use to configure your AutoFS
environment.
Table 12 AutoFS Configuration Variables
DescriptionVariable Name
Specifies if the system uses AutoFS. Set the value to 1 to specify that this system
uses AutoFS. Set the value to 0 to specify that this system does not use AutoFS. The
default value of AutoFS is 1.
NOTE: If you set the value of AUTOFS to 1, the NFS_CORE core configuration
variable must also be set to 1.
AUTOFS
Specifies a set of options to be passed to the automount command when it is
run. The default value is “ ” .
NOTE: The specified options take effect only if the automount command is run
from the AutoFS startup script.
AUTOMOUNT_OPTIONS
Specifies a set of options to be passed to the automountd daemon when it is
started. The default value is “ ” .
NOTE: The specified options take effect only if the automountd daemon is run
from the AutoFS startup script.
AUTOMOUNTD_OPTIONS
Specifies the name of the AutoFS master map. The default value is /etc/
auto_master.
NOTE: The AUTO_MASTER option can only be used with the /etc/
rc.config.d/nfsconf file.
AUTO_MASTER
When AutoFS starts up, and if the AUTOMOUNT_OPTIONS variable specifies a master map file
with the -f filename option, AutoFS searches for a file by that name on the local host. It can
also use the Name Service Switch (NSS) to determine which name services are in use. In addition,
it determines the master maps that are available from those name services.
If the AUTOMOUNT_OPTIONS variable does not specify the -f filename option, AutoFS consults
the NSS configuration, to determine where to search for the AutoFS master map.
For more information on configuring the NSS, see nsswitch.conf (4) and automount(1M) .
To configure AutoFS using the /etc/rc.config.d/nfsconf file, follow these steps:
1. Log in as superuser.
2. Edit the /etc/rc.config.d/nfsconf file. For instance, to change the default time for
which a filesystem remains mounted when not in use, modify the AUTOMOUNT_OPTIONS
variable, as follows:
AUTOMOUNT_OPTIONS="-t 720"
3. Enter the following command to start AutoFS.
/sbin/init.d/autofs start
