  • umount: /mnt/cdrom: device is busy

    卸载目录时,当前位置不能处于要卸载的目录,否则卸载不成功

    Every wonder why sometimes you get this message when you try to un-mount a NFS drive or cdrom drive (不能卸载的情形)

    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       (有关的运行的进程)
    CODE
    root@homer:~# fuser -m /mnt/cdrom/
    /mnt/cdrom/: 24066c
    That shows you what process is using that directory. Now lets do a ps aux and see whats running (查看哪个进程使用了这个目录)
    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(杀死进程)
    CODE  
    root@homer:~# kill -9 24066
    root@homer:~#
    now you can un-mount  (可以卸载)
    CODE
    root@homer:~# umount /mnt/cdrom/
    root@homer:~#
