How to Unmount an SMB Share From a Directory You Own

To successfully unmount a share, you must own the mount point on which the share is mounted.

Determine the mount point of the share that you want to unmount.

Use one of the following commands to find shares that are mounted from an SMB server:

$ mount -v | grep 'type smbfs'
//solarsystem/tmp on /mnt type smbfs read/write/setuid/devices/dev=5080000
  on Tue Mar 29 11:40:18 2011
//solarsystem/files on /files type smbfs read/write/setuid/devices/dev=4800000
  on Mon Mar 28 22:17:56 2011

$ df -k -F smbfs
//solarsystem/tmp      1871312   70864 1800448     4%    /mnt
//solarsystem/files    8067749    8017 7979055     1%    /files

Unmount the share by specifying the name of the mount point, /mnt or /files in the previous step.
For example:
```
$ umount /mnt
```
