Cd won't eject

techrolla · 11-24-2003, 09:41 PM

I have read some other posts about the cd not ejecting and they didn't seem to help me. My cdrom works fine and everything, but when its not in use, I can't eject it. It says:
umount: /mnt/cdrom: device is busy
eject: unmount of `/dev/cdrom' failed

and nothings busy! I can't eject the cd with the button on the player either. If you can help at all I apreciate it. Thanks.

make sure you have permission to unmount the CD, sometimes the permission is set to Root by default, Login as root and change the permissions.

Also, make sure you aren't in /mnt/cdrom.
You have to be out of the directory before it will eject.

Yes ,you can be /mnt/cdrom or below /mnt/cdrom.

i had this happen to me, too.

i was logged in as root (i know, i know...), and i was trying to isntall a package from the fedora cd #1. it couldnt read the cd (yes, it was dirt- and scratch-free), and when i tried to eject it, i got the same error. Only cd it has happened to so far.

i rebooted, but it was still locked. i rebooted again, and ejected while booting fedora.

kinda wierd.

just my 2 cents.

Do..
fuser -m -v /mnt/cdrom
That will tell you what's using the cd. If you just want to kill them all do
fuser -k -m /mnt/cdrom
And they will all be dead

This as root of course. After that umount will work just fine.

fuser command doesn't exist in bash...

techrolla · 11-26-2003, 08:10 PM

ooo, I switch to csh and I found it

teval · 11-26-2003, 08:21 PM

It does, I use it

This happened to me as well.

I can use the command provided, that is no problem, but

Should this not be considered as a BUG?.

Cheers,

Nopes, what happens is you have programs that are using the CD.
Unlike windows you can't just remove it, and leave those programs hanging. Partiailly because of how Linux also treats any normal disk drive too, and how it writes to them.
fuser -k -m <drive>
kills all the programs that are using that disk, then it can safely be unmounted.

are you saying this works in bash? Because on my fedora, bash doesn't recognize the fuser command. After switching the shell to csh it finds it.

fuser is in /sbin, which is not in the default path for bash. You can run it by using /sbin/fuser.
