    Problems mounting CD-ROM after installing 10.2


    Yesturday I installed Slack 10.2, but was only able to get to it tonight. This time around I only installed the "a" and "ap" packages (very basic system). Everything went fine with the installation and configuration, but when I logged in as root, I wasn't able t mount the CD to get some more packages going.

    The file /var/log/messages was giving the following error:
    Code:
    UMSDOS: msdos_read_super failed, mount aborted.
    I tried mounting different CDs but got the same problem. Also reinstalled Slack 10.2 again with no luck.

    Anyone have any ideas?

    As far as I know all the possible ones to mount CDs.
    Code:
    # mount /mnt/cdrom
    
    # mount /dev/cdrom /mnt/cdrom
    
    # mount -t iso9660 /dev/cdrom /mnt/cdrom (this actually gave me an error saying the FS was wrong)
    I think that's it. I know there's nothing wrong with the CD because I can mount it just fine under Debian.

    What kernel are you using ?

    If you are on the default "bare.i" that will probably be 2.4.29 or similar. To run cd's with that you need to use "scsi emulation".

    Check your kernel:

    Code:
    uname -r
    If you are on a 2.4.X.X kernel then add:

    Code:
    append="hdc=ide-scsi"
    to "lilo.conf". Then run:

    Code:
    /sbin/lilo
    when you have finished and then reboot.

    You should now see the cd device recognised as a scsi device. Probably /dev/sr0. Amend your fstab and mount points accordingly and you should be away.

    My "lilo.conf" is below for your info:

    Code:
    $ cat /etc/lilo.conf
    # LILO configuration file
    # generated by 'liloconfig'
    #
    # Start LILO global section
    append="hdc=ide-scsi"
    boot = /dev/hda2
    message = /boot/boot_message.txt
    prompt
    timeout = 1200
    # Override dangerous defaults that rewrite the partition table:
    change-rules
      reset
    # VESA framebuffer console @ 1024x768x256
    vga = 773
    # Normal VGA console
    # vga = normal
    # VESA framebuffer console @ 1024x768x64k
    # vga=791
    # VESA framebuffer console @ 1024x768x32k
    # vga=790
    # VESA framebuffer console @ 1024x768x256
    # vga=773
    # VESA framebuffer console @ 800x600x64k
    # vga=788
    # VESA framebuffer console @ 800x600x32k
    # vga=787
    # VESA framebuffer console @ 800x600x256
    # vga=771
    # VESA framebuffer console @ 640x480x64k
    # vga=785
    # VESA framebuffer console @ 640x480x32k
    # vga=784
    # VESA framebuffer console @ 640x480x256
    # vga=769
    # End LILO global section
    # Linux bootable partition config begins
    image = /boot/vmlinuz
      root = /dev/hda2
      label = slackware
      read-only
    # Linux bootable partition config ends
    #Backup Image
    image = /vmlinuz.old
    root = /dev/hda2
    label = oldlinux

    ide-scsi isnt needed for mounting cd's on 2.4 at all

    its for cd writing support under 2.4 kernels for IDE burners, it is replaced on 2.6 with the much better 'ide-cd' module.

    you should be able to mount /dev/cdrom fine.

    Perhaps the cd you are trying to mount is just blank... try with other cd you know that is already recorded... whe you try to mount using -t iso9660 and it says that the fs is wrong, or you recorded with a diferent fs, like ext3, and should use -t ext3 or the cd is just raw...

    I've actually tried mounting a few CDs already with no luck. I know there's something on this CD since I can get it mounted under Debian.

    I'm using the 2.4.31 kernel (vmlinuz-ide-2.4.31 specifically), and my GRUB menu.lst is already configured to load the ide-scsi module, so even if that was the problem, it's not a problem.

    Hm... now that is strange... let me see...is your kernel the default kernel? Perhaps the kernel module for the iso9660 is missing? I am really 'disturbed' with this problem... You really gave me a challenge So, if possible, see if the module is compiled with the kernel, and if it is not, if it is loaded? I have to go now (yes, I do not have a social life, but I do go to school sometimes:P) I`ll be back later...

    I think you just found what the problem is, but I still don't know how to fix it. I checked lsmod, and there was no "isofs" listed. So I just did "modprobe isofs" and it gives me an error say the "device or resource busy". I do have the isofs module under the kernel module directory.

    Any ideas?
