6. Enter the following command to stop AutoFS:
/sbin/init.d/autofs stop
CAUTION: Do not kill the automountd daemon with the kill command. It does not
unmount AutoFS mount-points before it dies.
7. Enter the following command to start AutoFS with tracing enabled:
/sbin/init.d/autofs start
To Stop AutoFS Basic Tracing
To stop AutoFS tracing, kill AutoFS and restart it only after removing -T from
AUTOMOUNTD_OPTIONS.
AutoFS Tracing Output
Following is a sample tracing output of the mounting and unmounting of a filesystem.
Mount Event Tracing Output
The general format of a mount event trace is: MOUNT REQUEST: <time stamp>
<mount information> <other tracing> ... <other tracing>
MOUNT REPLY: <status>=mount statusThe <mount information> trace has the following
format (all on one line) :
name=<key>[<subdirectory>] <map>= map name <opts>=mount options
<path>=mount path <other tracing>
where:
<key>= the key value from the map
<subdirectory> = subdirectory (may be blank)
<map> = name of map
<opts> = mount options
<path> = mount path
<other tracing> = other trace information
The mount status option in the mount reply contains 0 if the mount is successful; it has non-zero
value when the mount is not successful.
The following is an example of a typical mount trace:
