autofs
—
automounter filesystem
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):
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).
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.
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.
- vfs.autofs.mount_on_stat
- Set to 1 to trigger mount on
stat(2)
on mountpoint. Defaults to 0.
To unmount all mounted
autofs
filesystems:
umount -At autofs
To mount
autofs
filesystems specified in
auto_master(5):
automount
auto_master(5),
automount(8),
automountd(8),
autounmountd(8)
The
autofs
driver first appeared in
FreeBSD 10.1.
