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 assign-
ments 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:
0 successful
1 failure
EXAMPLES
To turn on tracing, enter:
/usr/sbin/automountd -T
or
automountd -T
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 dependen-
cies on those mounted filesystems. A reboot may be necessary to resolve these issues.
