Every wonder why sometimes you get this message when you try to un-mount a NFS drive or cdrom drive
Code:
root@homer:~# umount /mnt/cdrom
umount: /mnt/cdrom: device is busy
umount: /mnt/cdrom: device is busy
root@homer:~#Well chances a process is running that is using that directory. To find out run
Code:
root@homer:~# fuser -m /mnt/cdrom/
/mnt/cdrom/: 24066cThat shows you what process is using that directory. Now lets do a ps aux and see whats running
Code:
root@homer:~# ps aux | grep 24066
root 24066 0.0 0.5 2244 1284 pts/10 S 14:04 0:00 -su
root@homer:~#Looks like a the root user is in that directory. If you cannot find the term that is in that directory then kill that process
Code:
root@homer:~# kill 24066
root@homer:~#now you can un-mount
Code:
root@homer:~# umount /mnt/cdrom/
root@homer:~#This tip brought to you by the letter J and the letter Y
