Slackware 11.0 CD2 ISO image mountable, but physical CD not
 

Hi there,

first let me confirm what hundreds of others here already said: Slackware 11.0 is simply excellent!

My installations went almost smooth, with just one snag:
I can't use install CD2. It doesn't mount.

I have tried that on two machines, an older one with just a CD drive, and a new one with a DVD-ROM drive and a DVD writer, and I have tried it with both DVD devices. I have also tried out different media: CD-R and CD-RW from three different vendors, altogether six discs.

However, the only way I can install packages from Slackware installation CD2 is to mount the ISO image using the loop device. This works just fine, and burning the image on CD media gives no error, so I don't think the image is defective.
And as I can mount all the other five Slackware discs from all three CD/DVD drives, it's probably not a hardware related problem.

Has anyone else seen similar problems? And a solution or an explanation?

Thanks in advance!

Hi,

Did you do a md5sum on the iso that you downloaded?

k3b did that check, and the result was that the image is ok.

I've also downloaded the image another time and tried again --- same result.

gargamel

Just a guess

Download iso from different mirror.
or
burn with different software.

Thanks for your tip. I downloaded the image from another mirror and the torrent from slackware.com. Result is always this:

- MD5 check ok
- burning on medium: ok
- but then, trying to mount:

# mount /mnt/cdrom
mount: Not a directory

This means, that somehow the system notices that there is a CD in the drive, otherwise the error message would be something like "mount: No medium found".

It's not a big problem, as I could complete all my installations by mounting the ISO image directly with -o loop and installing the packages from that. However, I am curious, and just would like to know the cause of this little problem...

It may be possible that cd 1 is not getting unmounted.

try dmesg

How do you mount iso image to install? I also want to install live cd but don't have cd drive.

mount -t iso9660 <filename-of-disc-image> /mnt/cdrom -o loop

Not sure, if that helps you with your live cd...

gargamel

No, this is not the problem. No CD remains mounted. BTW, it's not possible to remove a cd from the drive, when it is mounted.
- The command eject issued as root unmounts the disc first before the slider (what's the English word for the part of a CD drive where the CD is?)
- If a CD is mounted, the physical keys on the drive to open the slider (see above...) are locked

So the effect must be caused by something else...

gargamel

umount it manually

umount /mnt/cdrom check the mount point location
or
umount /dev/cdrom

Thanks, but there was a misunderstanding, it seems:

When I said, that there don't remain any other CDs mounted, I was sure of that, because I had unmounted them all, just like you suggest. Depending on the options used for mounting (issued with the mount command or specified in /etc/fstab) it may be necessary to do this as root.

And, of course, I have checked, what's mounted afterwards, by just issuing mount without any options. My harddiscs and other mounted peripherals were listed, but no CD drives. So I think, there is something special with CD2. Because I have no problem to mount any of the other five Slackware discs.

The question is: What's the difference?

gargamel

If cd2 work fine on other system then I guess problem is with this specific installed distro.

I doubt there is something like repair install as in windows which will fix the missing/damaged files.

No, again a misunderstanding.
CD2 doesn't mount anywhere, not on SuSE, not on Slackware, just nowhere. CD1 and 3-6 mount everywhere, without any problems.

Weird, isn't is?

gargamel

yeah.

try to mount cd2 first.
Download dvd or order slack cd and check that.

DVD works just fine. Slack CD is ordered, of course, as I subscribed.

Mounting CD2 first: How should that help...?
BTW, I booted only CD2 after completely restarting my computer (after power-off!), with no improvement.

Anyhow, it's not all that important. Slack 11 runs just fine everywhere I want it so.
