Unmounting a File System

Use the umount command to unmount a currently mounted file system.

How to Unmount a File System

To unmount a file system, use the following syntax:


  umount special  | mount_point 

Specify the file system to be unmounted as a mount_point or special (the device on which the file system resides). See the umount_vxfs(1M) manual page for more information about this command and its available options.


Example

To unmount the file system /dev/vx/dsk/fsvol/vol1, enter:


 # umount /dev/vx/dsk/fsvol/vol1

To unmount all file systems not required by the system, enter:


 # umount -a 

This unmounts all file systems except / (root), /usr, /var, /opt, and /tmp.
