How do I see what processes are touching specific devices

I am trying to eject my CDROM and I can't because it claims the device is buys, is there a command I can run to see what process is touching the cdrom?

Here's something that usually, but not always, works. It's a command called "fuser". Open a console and su to root. To see what is tying up your CD drive run:

# fuser -vm <insert mount point for cd drive>

For me that's:

# fuser -vm /mnt/cdrom

You will get a printout of the processes using the device with the PID number of each process. You can then kill the process by running:

# kill <insert PID>

There's even a shorter way though. If you run:

# fuser -km /mnt/cdrom

All processes accessing the cd drive will be killed. After killing the processes tying up the drive, be sure to unmount the drive in your console:

# umount /mnt/cdrom

You should then be able to get the cd out of the drive. For more info on fuser, see man fuser.
