On SuSE, the default mount point for the cdrom is /cdrom not /mnt/cdrom
so the command would be

umount /cdrom

If the device is not busy, "eject" will generally works as well.

One thing I've found is that if a process dies an unnatural death
while doing cdrom i/o, that "device busy" state never gets cleaned
up--and hence, umount and eject will fail.

The thing to do here, is first see if you have any shells that have
/cdrom as the top of its current working directory.  Then see if any
other processes are trying to access the cdrom.  Kill them all and let
cron sort them out.

If you're *still* not able to umount, you can reboot and depress
the "release me" button on the cdrom drive before the system gets
a chance to start diddling with the cdrom drive.  If THAT doesn't
work, shutdown and power off  and then try manually ejecting the
thing by sticking an unbent paperclip into the little hole on the
front of the cdrom drive.

No supermount in SuSE.  And since the default mount point for the cdrom
in SuSE is /cdrom, that would be

mount /cdrom
