/usr/sbin/umount local_directory
/usr/sbin/mount local_directory
2. If you change the mount options in the AutoFS master map, you must restart
AutoFS for the changes to take effect. For information on restarting AutoFS, see
“Restarting AutoFS” (page 103).
For more information on the different caching mount options, see mount_nfs(1M).
Unmounting (Removing) a Mounted Directory
You can temporarily unmount a directory using the umount command. If you want
to stop a directory from being automatically mounted upon server restart or system
reboot, remove it from the /etc/fstab file.
NOTE: Before you unmount a directory, run the fuser -cu command to determine
whether the directory is currently in use. The fuser command lists the process IDs
and user names of all the processes that are using the mounted directory. If users are
accessing the mounted directories, they must exit the directories before you unmount
the directory.
To unmount a mounted directory and prevent it from being automatically mounted,
follow these steps:
Automatic Unmount
1. To check for any processes accessing the mounted directory, enter the following
command:
fuser -cu mounted_directory
2. To kill the processes, enter the following command:
fuser -ck local_mount_point
3. Unmount the filesystem as follows:
/usr/sbin/umount mounted_directory
4. If the unmount fails, use the forcible option to unmount the filesystem:
/usr/sbin/umount -f mounted_directory
5. Verify whether all the directories are unmounted by entering the following
command:
mount
The directories that you have unmounted must not be present in the list displayed.
6. If you do not want the directory to be automatically mounted when the system is
rebooted, remove the directory entry from the /etc/fstab file.
