When I mount the cdrom with #mount -t cd9660 /dev/acd0c /cdrom
Verb. Sap. Make that:
# mount -t cd9660 -o ro /dev/acd0c /cdrom
For best results, set up all of the options etc. in /etc/fstab, and then just use:
# mount /cdrom
everything works fine.I can get to my ports and everything But when I want to swap cds and I type #umount /cdrom I get this error message:: Unable to umount /cdrom, Device is busy. If I do the umont from KDE I get the same error message. What I'm doing wrong??
You've either got a process with it's current working directory somewhere under /cdrom, or you've got a process with an open file descriptor (or a memory map) on one of the files on the CD.
Try using:
# fstat -f /cdrom
to see if you can identify the culprits. Then either close them down, or CD to elsewhere in the filesystem if it's an interactive session. Once the CD Rom is idle, you should be able to dismount it easily.
To elaborate on what Matthew was saying, if you cd /cdrom once it's mounted, and you try to unmount, you're going to get an error. I always make certain to cd back home and the unmount the CD. You can't unmount a device that you're currently 'on.'
