    try fuser, it should show if someone or something is in the directory in question.

    so man fuser

    eg

    [root@vinson etc]# fuser /mnt/ (gives no return)
    [root@vinson etc]# cd /mnt/
    [root@vinson mnt]# fuser /mnt/
    /mnt/: 16337c
    [root@vinson mnt]# ps aux |grep 16337
    root 16337 0.0 0.0 4268 1372 pts/0 S 08:19 0:00 -bash
    root 16408 0.0 0.0 3676 676 pts/0 S 08:25 0:00 grep 16337

    So this shows "me" as root in a bash shell in /mnt so /mnt cannot be ejected/unmounted while "I" am in there. This should work for where ever the cd is mounted.

    regards

    Jerry, you reported:

    > I get the same problem even as root:

    > debian:/home/jerry# mount /dev/hdc
    > debian:/home/jerry# umount /dev/hdc
    > debian:/home/jerry# eject /dev/hdc
    > eject: unable to eject, last error: Invalid argument

    ...two weeks ago in a thread on ejecting a CD problem.

    Did you ever find a solution?

    I've got the exact same problem on my recently Debianed box.

    I didn't see any solution on the list, although other threads discussed
    when only root can eject. I can't eject, even as root:

    habanero:/etc# eject /dev/hdc
    eject: unable to eject, last error: Invalid argument
    habanero:/etc# eject /media/cdrom
    eject: unable to eject, last error: Invalid argument
    habanero:/etc#

    My fstab is:

    # /etc/fstab: static file system information.
    #
    # <file system> <mount point> <type> <options> <dump> <pass>
    proc /proc proc defaults 0 0
    /dev/hda6 none swap sw 0 0
    /dev/hda3 / ext3 defaults,errors=remount-ro 0 1
    /dev/hda5 /home ext3 defaults 0 2
    /dev/hdc /media/cdrom iso9660 ro,user,noauto 0 0
    /dev/fd0 /media/floppy auto rw,user,noauto 0 0
    endor:/export/home6/emonsler /home/emonsler/nethome nfs defaults,_netdev

    Finally, uname -s reports:

    Linux habanero 2.4.26-1-686-smp #1 SMP Fri Jul 9 22:32:32 JST 2004 i686
    GNU/Linux

    Thanks,

    Eric
