[root@rhe11 /]# umount -f /home/download
umount2: Device or resource busy
umount: /home/download: device is busy
umount2: Device or resource busy
umount: /home/download: device is busy


-f is a force option, why it still wont work?

Thanks.

My guess is that something is being written within the directory, or you have something running within the directory. Out of curiosity, is this directory on a seperate drive?

If /home/download is on a separate drive or partition, then you can umount. If it is just a subdirectory of /home, then you can't. You can umount /home if it is on a separate drive though.

When you umount, your Present Working Directory can not on the device you are umounting. To find out, use the command "pwd". Eg: if pwd is /home/download/ then you can not umount /home/download

I hope this helps

/dev/mapper/mystore-download on /home/download type ext3 (rw)

Try

lsof | grep download

This will tell you if any proces is still using some files inside this directory.

A
ps -auxww
Should also show you if any process is using the directory and not allowing it to unmount

Cheers

lsof | grep download

showed me the user accessing the file/directory.

How do I kick him?

Thanks.

See if its a process accessing the directory.
If its a process kill that process with a
kill -9 pid

[The process id can be obtained from lsof output ]

Or try a
w
and see if any user is connected through network and accessing your download directory.

Also see if ps -auxwww is of any help.

Cheers
Zulfi
