Question cdrom will not unmount.

I have been trying to work on getting this to work for some time now but still no luck. What I'm trying to do is get Diablo II installed and when I need to change out disks i issue:

# umount /dev/cdrom

and get:

mount: /mnt/cdrom: device is busy

im not sure whats wrong... Any help would be nice.

You have to start the installation from another directory than /mnt/cdrom/. Try to stand in your home directory and start the installer with wine(x) /mnt/cdrom/setup.exe

I have run into this - sometimes it seems to be solved if I wait about a minute and then try again to unmount. Also, make sure that nothing "else" in you system is using the CD-ROM. On my Rh9 system for example, if I insert a CD into the drive under KDE, the CD gets mounted automatically and Konqueror starts up to show me the contents. It is easy to forget that the Konqueror windows is still open and then to try and unmount the drive - which fails of course because umount detects that a process is using the CD (Konqueror) and thus refuses to allow me to unmount. The solution usually is to close the Konqueror session, wait about 30 seconds, and then try to unmount, which usually works.

Maybe you have some process other than the Diablo install accessing the CD and that is why your system refuses to unmount?

Okay, the best way I've found of installing a two disk (or more game) is as follows:

1) Open two terminals
2) In the first, type 'su' and enter your root password when prompted. This terminal is now the 'root' terminal

In the 'root' terminal:

# mount /mnt/cdrom (or as required)

In the second terminal, the 'user' terminal, run the install program.
On disk change, go back to the 'root' terminal:

# umount /mnt/cdrom && eject /mnt/cdrom && sleep 5 && eject -t /mnt/cdrom && mount /mnt/cdrom

(That will give you 5 seconds to change disks before the cdrom driver gobbles it up again, adjust as necessary)

It's always best to copy any install script (such as the UT2k3 install script on disk 3) into /tmp and run it from there.

Good luck, let us know how it gets on!

Hm... You can try to install with install.exe instead of setup.exe.

You can force an unmount with the -f option.

/dev/cdrom is not by any chance the drive you're
running Knoppix off? :)
