umount drive partition: device is busy?

lefty.crupps · 06-21-2006, 08:00 PM

My hard drive is cut up into partitions and one of them is mounted within my home directory (K6.06 Dapper). I would like to unmount it. When i try, i am told that it's busy:

Code:

lefty@crupps:~$ sudo umount /home/lefty/bigboi
umount: /home/lefty/bigboi: device is busy
umount: /home/lefty/bigboi: device is busy
lefty@crupps:~$

I do not have Kerry/beagle nor my Amarok currently running (I do have klipper, kdewallet, kmixer, kopete, and Skype running in my System Tray).

I cannot think of any reason why this would be busy! How do I unmount this drive?

You can use the "fuser" command to tell you which process is accessing that partition.

Can you post the output of "mount" and "cat /etc/fstab" ?

forcefully umount with -f (i think) option
or check for this option in man pages

I think this is it:

Code:

lefty@crupps:~$ fuser -c /home/lefty/bigboi
/home/lefty/bigboi:  5634  5924

lefty@crupps:~$ ps -p5634
  PID TTY          TIME CMD
 5634 ?        00:00:01 beagled
lefty@crupps:~$ ps -p5924
  PID TTY          TIME CMD
 5924 ?        00:04:05 amarokapp

Perhaps the KDE system tray isn't quite accurate?

Thank you three for your help! I always learn something

I've found KDE's ability to properly manage processes is deficient in certain areas. This is especially noticeable with Konqueror. I can close and re-open it 6 times and then have 6 separate Konqueror processes in the process list, despite none being open. This is my experience with releases up to 3.4 anyhow. 3.5 may be different.

hello

since you are using the partition as your home directory, and since for every user logged-in a home directory is a must, may be that is withhelding the umounting. you log-off first and then try to unmount.

No its just a mounted partition (sda6) in a subfolder (./bigboi) of my home directory.

Didn't see your output, but if it's under /home, and /home is mounted, it's busy, right?
