Check if your cdrom is really mounted with the mount command and the mount point.

You can also use the "eject" command.

Oooops... sorry, the problem was to "mount", not umount.

Ok, (mount: No medium found).

You don't have a cdrom specification in fstab, so you should use the full mount command, for example:

mount /dev/cdrom /media/cdrom

If /dev/cdrom does not works, then try with /dev/hda /dev/hdb /dev/hdc or /dev/hdd dependind of where is connected your cdrom. You can check this from the output of dmesg.

Here is what i use in fstab of my RHEL servers

/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0

You may try mount w/o an fstab entry

mount -F iso9660 /dev/devicefile /mountpoint
