|AUTOMOUNT(8)||System Manager's Manual||AUTOMOUNT(8)|
- -h, --help
- Print brief help on program usage.
- -p, --pid-file
- Write the pid of the daemon to the specified file.
- -t <seconds>, --timeout <seconds>
- Set the global minimum timeout, in seconds, until directories are unmounted. The default is 10 minutes. Setting the timeout to zero disables umounts completely. The internal program default is 10 minutes, but the default installed configuration overrides this and sets the timeout to 5 minutes to be consistent with earlier autofs releases.
- -M <seconds>, --master-wait <seconds>
- Set the maximum time to wait for the master map to become available if it cannot be read at program start.
- -n <seconds>, --negative-timeout <seconds>
- Set the default timeout for caching failed key lookups. The default is 60 seconds.
- -v, --verbose
- Enables logging of general status and progress messages for all autofs managed mounts.
- -d, --debug
- Enables logging of general status and progress messages as well as debugging messages for all autofs managed mounts.
- -Dvariable=value, --define variable=value
- Define a global macro substitution variable. Global definitions are over-ridden macro definitions of the same name specified in mount entries.
- -S, --systemd-service
- Used when running the automounter as a systemd service to ensure log entry format is consistent with the log entry format when running as a daemon.
- -f, --foreground
- Run the daemon in the foreground and log to stderr instead of syslog."
- -r, --random-multimount-selection
- Enables the use of random selection when choosing a host from a list of replicated servers.
- -m, --dumpmaps [<map type> <map name>]
- With no parameters, list information about the configured automounter
maps, then exit.
If the dumpmaps option is given and is followed by two parameters, "<map type> <map name>" then simple "<key, value>" pairs that would be read in by a map read are printed to stdout if the given map type and map name are found in the map configuration.
If the map is an LDAP map and there is more than one map of same name in different base dns only the first map encountered by autofs will be listed. Similarly, if the map is a file map and there is more than one map of the same name in different directories, only the first map encountered will be listed.
If the map type is an old style multi-map and any one of the map names in the multi-map entry matches the given map name the entries that would be used by autofs for the whole multi-map will be listed.
- -O, --global-options
- Allows the specification of global mount options used for all master map entries. These options will either replace or be appended to options given in a master map entry depending on the APPEND_OPTIONS configuration setting.
- -V, --version
- Display the version number, then exit.
- -l, --set-log-priority priority path [path,...]
- Set the daemon log priority to the specified value. Valid values include
the numbers 0-7, or the strings emerg, alert, crit, err, warning, notice,
info, or debug. Log level debug will log everything, log levels info, warn
(or warning), or notice with enable the daemon verbose logging. Any other
level will set basic logging. Note that enabling debug or verbose logging
in the autofs global configuration will override dynamic log level
changes. For example, if verbose logging is set in the configuration then
attempting to set logging to basic logging, by using alert, crit, err or
emerg won't stop the verbose logging. However, setting logging to debug
will lead to everything (debug logging) being logged witch can then also
be disabled, returning the daemon to verbose logging. This option can be
specified to change the logging priority of an already running automount
The path argument corresponds to the automounted path name as specified in the master map.
- -C, --dont-check-daemon
- Don't check if the daemon is currently running (see NOTES).
- -F, --force
- Force an unlink umount of existing mounts under autofs managed mount points during startup. This can cause problems for processes with working directories within these mounts (see NOTES).
- Location for autofs master map that defines autofs managed mount points and the mount maps they will use. The default is auto.master.
If any autofs mount point directories are busy when the daemon is sent an exit signal the daemon will not exit. The exception to this is if autofs has been built with configure options to either ignore busy mounts at exit or force umount at exit. If the ignore busy mounts at exit option is used the filesystems will be left in a catatonic (non-functional) state and can be manually umounted when they become unused. If the force umount at exit option is used the filesystems will be umounted but the mount will not be released by the kernel until they are no longer in use by the processes that held them busy. If automount managed filesystems are found mounted when autofs is started they will be recovered unless they are no longer present in the map in which case they need to umounted manually.
If the option to disable the check to see if the daemon is already running is used be aware that autofs currently may not function correctly for certain types of automount maps. The mounts of the separate daemons might interfere with one another. The implications of running multiple daemon instances needs to be checked and tested before we can say this is supported.
If the option to force an unlink of mounts at startup is used then processes whose working directory is within unlinked automounted directories will not get the correct pwd from the system. This is because, after the mount is unlinked from the mount tree, anything that needs to walk back up the mount tree to construct a path, such as getcwd(2) and the proc filesystem /proc/<pid>/cwd, cannot work because the point from which the path is constructed has been detached from the mount tree.
The documentation could be better.
