Thread: mount: can't find /media/cdrom in /etc/fstab or /etc/mtab

  1. mount: can't find /media/cdrom in /etc/fstab or /etc/mtab

    On my Fedora 8 x86_84 system, /media/cdrom has disappeared. I suspect this is
    the result of a yum update, but I need help diagnosing the problem.

    1. There is no /media/cdrom when I put a CD or DVD into the drive.
    If I type "mount /media/cdrom", I get the message:

    mount: can't find /media/cdrom in /etc/fstab or /etc/mtab

    Here is /etc/fstab:

    /dev/VolGroup00/LogVol00 / ext3 defaults 1 1
    LABEL=/boot /boot ext3 defaults 1 2
    tmpfs /dev/shm tmpfs defaults 0 0
    devpts /dev/pts devpts gid=5,mode=620 0 0
    sysfs /sys sysfs defaults 0 0
    proc /proc proc defaults 0 0
    /dev/VolGroup00/LogVol01 swap swap defaults 0 0

    Here is /etc/mtab:

    /dev/mapper/VolGroup00-LogVol00 / ext3 rw 0 0
    proc /proc proc rw 0 0
    sysfs /sys sysfs rw 0 0
    devpts /dev/pts devpts rw,gid=5,mode=620 0 0
    /dev/sda1 /boot ext3 rw 0 0
    tmpfs /dev/shm tmpfs rw 0 0
    none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0
    sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 0 0
    fusectl /sys/fs/fuse/connections fusectl rw 0 0

    2. I looked at my Fedora 8 laptop, and the fstab file is identical to
    the one shown above, but the CDROM drive works fine on that machine.

    3. It does not appear to be an SE-Linux problem because if I change SE-linux to
    permissive mode, the problem persists.

    4. Could it be a kudzu problem? If I go into Services and try restarting kudzu,
    I get the message:

    kudzu failed. The error was: Usage /etc/init.d/kudzu {start|stop}

    5. The drive stopped working sometime after I did a recent round of yum updates
    on Oct. 2 and Oct. 3. Perhaps these yum.log messages will give a clue:

    6. Yes, I have tried putting disks into and out of the drive, and rebooting
    numerous times.

    Where do I go from here?

  2. Re: mount: can't find /media/cdrom in /etc/fstab or /etc/mtab

    I forgot to mention that I also tried booting my machine from the
    Fedora 8 Live DVD, and the system came up just fine. This shows
    that the hardware is okay.

    [top-posting corrected]

    Maybe the working machine has a daemon that creates a dir and mounts the cd
    automagically. A daemon which is not running on the problem machine. I also
    don't have an entry /mnt/cdrom in fstab - everything on my Gentoo system is
    done by HAL/udev and KDE's service for removable media.

    Windows is great - you can download Linux with it.

    As root type this:

    mkdir /media
    mkdir /media/cdrom
    mount /dev/cdrom /media/cdrom

    It's not that simple. Linux has daemons that check for new
    hardware and create directories like /media/cdrom as needed.
    /media/cdrom depends on there being one or two other directories
    in /dev, which have to be configured correctly for anything at all
    to be mounted.

    I did try what you have above, which resulted
    in the message:

    mount: /dev/cdrom is not a block device


  6. Re: mount: can't find /media/cdrom in /etc/fstab or /etc/mtab

    I had a similar problem and followd your directions:

    mkdir /media
    mkdir /media/cdrom
    mount /dev/cdrom /media/cdrom

    And it worked for me. I'm running SLES10SP2. Why would I be missing the /media/cdrom directory?
