Did you ever had a problem to unmount a drive/share on a linux system? Maybe the mount share is not accessible but the mount still there.
Example:
umount /mnt/blah
unmount error 16 = Device or resource busy
Refer to the umount.cifs(8) manual page (man 8 umount.cifs)
You can do the following:
umount -f /mnt/blah
If it doesnt work, use the lazyness method:
umount -l /mnt/blah
Test if your mount is still mounted with the command mount
mount
What man say about umount
man umount
-f Force unmount (in case of an unreachable NFS system). (Requires
kernel 2.1.116 or later.)
-l Lazy unmount. Detach the filesystem from the filesystem hierar-
chy now, and cleanup all references to the filesystem as soon as
it is not busy anymore. (Requires kernel 2.4.11 or later.)
--------
If you want to know what processes are keeping the filesystem busy, you can do:
fuser -m /mnt/blah
Example:
umount /mnt/blah
unmount error 16 = Device or resource busy
Refer to the umount.cifs(8) manual page (man 8 umount.cifs)
You can do the following:
umount -f /mnt/blah
