cdrom mount problem

[Murugs]

setup:Redhat Linux 7.1
when I mount my cdrom I get the following error.

mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
(could this be the IDE device ....)

any ideas how to get it working.

It's possible the CD is bad. Does it work on another machine? Also, exactly what command are you using to mount the cdrom, and what are the contents of your /etc/fstab? Bruce Garlock

What is the command you use to mount the CD?

 

[Murugs]

I use mount /dev/cdrom.

my etc/fstab contents are

LABEL=/ / ext2 defaults 1 1
LABEL=/boot /boot ext2 defaults 1 2
LABEL=/home /home ext2 defaults 1 2
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
LABEL=/usr /usr ext2 defaults 1 2
LABEL=/var /var ext2 defaults 1 2
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/sda5 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0

After you run the mount command, type in 'dmesg' and post the output. Did you get a chance to try the CD in a known working machine? Do other CD's work in this machine? If the CD has been burned by someone, has the session been closed? Bruce Garlock

The CDROM comes from a software vendor..and working on another machine.

I have the dmesg output. It is very long and I think it cannot be posted here..I can mail it to you if you are interested.

But the tail of the dmesg output is below
Internal registers self-test: passed.
ROM checksum self-test: passed (0x04f4518b).
scsi2 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: TEAC Model: CD-532E-B Rev: 2.1A
Type: CD-ROM ANSI SCSI revision: 02
probable hardware bug: clock timer configuration lost - probably a VIA686a motherboard.
probable hardware bug: restoring chip configuration.
ide-scsi: hda: unsupported command in request queue (0)
end_request: I/O error, dev 03:00 (hda), sector 64
isofs_read_super: bread failed, dev=03:00, iso_blknum=16, block=32

Sorry, I meant to say just post the tail end, and you did

Looks like it may be a hardware issue. Do you have the latest kernel for RH 7.1? Maybe it was a bug in the kernel, that is now fixed. The latest is:

http://rhn.redhat.com/errata/RHSA-2002-262.html

'uname -a' will show you your latest kernel, which should be: 2.4.18-18.7.x

If you are not at the latest kernel, please update. If you are, then you may have found a bug, or you have defective hardware, like the dmesg output states. Bruce Garlock
