Moutning problems

[Shifty]

I've changed my permissions but if I want to unmount one of my cdroms it gives an error saying the device is busy. It also can't software eject. Can someone please help me?

Do you have the cdrom open in any other windows? Is your terminal in the cdrom directory? If you absolutely need it unmounted, try:

umount -fl /dev/hdc

or whatever the device is.

If ur gettin this error, u have something open that is in the cd directory somewhere.

Make sure u dont have any file browsers open in the /mnt/cdrom directory or any shells there either.

If u still cant unmount it, try:

fuser /mnt/cdrom

that will tell u what process is using the drive, then kill it with:

kill <PID>

<PID> is the PID shown be fuser

then try unmount again.

Or if the process is zombie or you can't even kill it with kill -9, try the -l switch to umount like I said. (Although that's highly unlikely as the signal sent by kill -9 cannot be handled by the program. it just kills it no matter what)

yeah!!

In worst case if the CD does not come out at all, you have to kill the relevant processes involved with CD operations, first try to identify the processed using cd - rom, with command ps with option -afe, then fill them one by one which are involved with cd-rom operation.

Thanks to everyone who replied. I am sure I can use what you said.
