When I try to mount my ATAPI CD-ROM (I have two Pioneers as masters on 2-IDE and a Delta as slave on 2-IDE; both drives are recognized by the kernel as hdc and hdd), I get an error message which states, “mount fs: type 9660 not supported by kernel”. I have tried to modify the /etc/fstab with:

/dev/hdc /mnt/cdrom iso9660 noauto 0,0
/dev/hdd /mnt/cdrom01 iso9660 noauto 0,0

I still get the same error. Can you help me? —Kim Nielsen, Red Hat 5.1

This is happening because your kernel wasn't compiled to support the iso9660 file system, and you don't seem to be able to load the module. Try this first:

moremagic:~# cat /proc/filesystems
nodev proc
nodev autofs
nodev nfs

If you don't see iso9660, you should have an isofs module (unless you recompiled your own kernel). If typing insmod isofs and then mounting your CD-ROM works, your problem may be that kerneld isn't running. Try:

moremagic:~# ps auxww | grep kernel[dD]
root 38 0.0 0.3 756 364 ? S 01:15 0:00 /sbin/kerneld

If kerneld is not there, you will need to start it yourself. —Marc Merlin,

As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.
