Unable to mount CDROM - CDFS not found?

Hi,

I have an old Fedora Core 4 box with LTSP. It has older workstations and thinclients connecting to it, some with a cdrom and some without. The problem is that I cannot get the CDROM on either the server or the workstations themselves to work.

I'm not sure if I simply need to install cdfs, but I can't for the life of me work out how.

Any help would be appreciated.

Cheers

After inserting the cd run 'dmesg' and look for clues at the bottom.

Has it ever worked with cd's on the server?

Try mount it with filesystem iso9660

Do you know that this is not an iso9660 CD?
The only CD-ROM/DVD filesystems offerred by the kernel configurator "make xconfig" are ISO9660 and UDF

Find below the output of dmesg. I'm not quite sure what you meant by your comment duncan.

To avoid uncessary complication I inserted a CD directly in to the CDROM of the server, and tried to mount with the following:

mount -t iso9660 /dev/hdc /media/cdrom

mount: no medium found

I meant that there is no CDFS supported by Linux, only ISO9660 and UDF.
It looks like your drive is not able to make sense of the CD. Different drives indicate this in different ways: some flash their lights for ever - is yours doing that?
dmesg reports that your CD-ROM drive is a standard item.

You're sure that your cdrom is a data cdrom? (For example, audio cdroms don't have a filesystem to mount.)

As others have said, "cdfs" is an invalid filesystem type.  "iso9660" would usually be the appropriate type, but this should be auto-detected.

It seems that either you don't have a data CD in the drive, as ifreq suggested, or that your CD-ROM drive is not properly recognizing that CD.  "No medium detected" would imply that it can't find a valid CD in the drive... you'd probably be getting data read errors if it was an audio CD, or blank CD, my guess is it's not seeing any CD at all.

Are you sure it's a valid CD, and not a blank CD-RW or a DVD?

Hi,

Thanks for the replies. I will ensure that the CD is a data CD. A couple of the workstations use LTSP DC Boot disks so I will get them to try this and let you know the result.

Cheers

Hi, sorry for the delay. In the end I didn't get the problem fixed, not sure whats wrong. I think this has something to do with LTSP.
