AUTOFS(5)

NAME
autofs - automounter filesystem

SYNOPSIS
To compile this driver into the kernel, place the following line in the kernel configuration file:

options AUTOFS

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

    autofs_load="YES"

DESCRIPTION
The autofs driver is the kernel component of the automounter infrastructure. Its job is to pass mount requests to the automountd(8) daemon, and pause the processes trying to access the automounted filesystem until the mount is completed. It is mounted by the automount(8).

OPTIONS
These options are available when mounting autofs file systems:

master_options
    Mount options for all filesystems specified in the map entry.

master_prefix
    Filesystem mountpoint prefix.

SYSCTL VARIABLES
The following variables are available as both sysctl(8) variables and loader(8) tunables:

vfs.autofs.debug
    Verbosity level for log messages from the autofs driver. Set to 0 to disable logging or 1 to warn about potential problems. Larger values enable debugging output. Defaults to 1.

vfs.autofs.interruptible
    Set to 1 to allow mount requests to be interrupted by signal. Defaults to 1.

vfs.autofs.retry_delay
    Number of seconds before retrying mount requests. Defaults to 1.

vfs.autofs.retry_attempts
    Number of attempts before failing mount. Defaults to 3.

vfs.autofs.cache
    Number of seconds to wait before reinvoking automountd(8) for any given file or directory. Defaults to 600.

vfs.autofs.timeout
    Number of seconds to wait for automountd(8) to handle the mount request. Defaults to 30.

EXAMPLES
To unmount all mounted autofs filesystems:

    umount -At autofs

To mount autofs filesystems specified in auto_master(5):

    automount
