NAME
automountd — autofs mount/unmount daemon
SYNOPSIS
automountd[-TvnL]
[-D
name=value]
DESCRIPTION
automountd
is an
RPC
server that answers file system mount and unmount requests
from the
autofs
filesystem.
It uses local files or name service maps to locate filesystems
to be mounted.
These maps are described with the
automount
command (see
automount(1M)).
The
automountd
daemon is automatically invoked if the
AUTOFS
variable is set to 1 in
/etc/rc.config.d/nfsconf.
Options
- -T
Trace. Expand each
RPC
call and display it to
/var/adm/automount.log.
- -v
Verbose. Log status messages to
/var/adm/syslog/syslog.log.
- -n
Turn off browsing for all
autofs
mount points.
This option overrides the
-browse
autofs
map option on the local host.
- -L
Force all mounts to the local host to be NFS mounts instead of
the default LOFS mounts.
This is necessary for highly available NFS mounts.
- -D name=value
Assign
value
to the indicated
automount
map substitution variable.
These assignments cannot be used to substitute variables
in the master map
auto_master.
Tracing
While
automountd
is running, the signal
SIGUSR2
can be sent to
automountd
to turn tracing on. It logs messages in
/var/adm/automount.log.
To turn tracing off, send the signal
SIGUSR2
again.
RETURN VALUE
automountd
returns:
EXAMPLES
To turn on tracing, enter:
or
No messages are displayed by the trace.
Check the results in
/var/adm/automount.log.
WARNINGS
Any filesystems that are being
managed by
autofs
should never be manually mounted
or unmounted. Even if the mount or unmount operation appears
to complete successfully, the resulting change of state to the
autofs
managed filesystem can lead to disruptive or unpredictable
results, including but not limited to: commands
hanging or not returning expected results, and applications
failing due to their dependencies on those mounted filesystems.
A reboot may be necessary to resolve these issues.
