Troubleshooting AutoFS
This section describes the tools and procedures for troubleshooting AutoFS.
AutoFS Logging
AutoFS logs messages through /usr/sbin/syslogd. By default, syslogd writes
messages to the file /var/adm/syslog/syslog.log. For more information on the
syslog daemon, see syslogd(1M).
To Start AutoFS Logging
To start AutoFS Logging, follow these steps:
1. Log in as superuser to the NFS client.
2. To find a list of all the automounted directories on the client, run the following
script:
for FS in $(grep autofs /etc/mnttab | awk ‘{print $2}’)
do
grep ‘nfs’ /etc/mnttab | awk ‘{print $2}’ | grep ^${FS}
done
3. For every automounted directory listed by the grep command, enter the following
command to determine whether the directory is currently in use:
/usr/sbin/fuser -cu local_mount_point
This command lists the process IDs and user names of all the users who are using
the mounted directory.
4. Warn users to exit the directory, and kill any processes that are using the directory,
or wait until the processes terminate. Enter the following command to kill all the
processes using the mounted directory:
/usr/sbin/fuser -ck local_mount_point
5. Enter the following command to stop AutoFS:
/sbin/init.d/autofs stop
6. Add -v to AUTOMOUNTD_OPTIONS variable in the /etc/rc.config.d/nfsconf
file, as follows:
AUTOMOUNTD_OPTIONS = “-v”
This change enables AutoFS logging.
7. Enter the following commands to start AutoFS:
/sbin/init.d/autofs start
