Serious mount/umount problems...
 

This is killing me now... I've asked every guru I know and they have no idea...

I'm trying to install Neverwinter Nights, the linux one. I've downloaded the installed for it (the 24MB one which patches after it's installed) and I'm having problems with it. I can't change CD's.

The first CD went fine, but then I ran into problems.

Now I've got this:
[root@localhost cdrom]# mount
/dev/hda7 on / type ext2 (rw)
none on /proc type proc (rw)
none on /proc/bus/usb type usbdevfs (rw)
none on /dev type devfs (rw)
/dev/hda1 on /boot type ext3 (rw)
none on /dev/pts type devpts (rw,mode=0620)
/dev/hdb1 on /home type ext3 (rw)
none on /mnt/cdrom type supermount (ro,dev=/dev/scd0,fs=auto,--,iocharset=iso8859-15,codepage=850,umask=0)
none on /mnt/floppy type supermount (rw,sync,dev=/dev/fd0,fs=auto,--,iocharset=iso8859-15,codepage=850,umask=0)
/dev/hda6 on /usr type ext3 (rw)
/dev/hda8 on /var type ext3 (rw)
none on /mnt/cdrom type supermount (ro,dev=/dev/scd0,fs=auto,--,iocharset=iso8859-15,codepage=850,umask=0)
none on /mnt/cdrom type supermount (ro)

Good old supermount...

My question: Is there a way to forcably drop a mount?

Some things I've tried to get around it are below. (this is a direct copy from the command window, so it's quite long...)

Try following these guidelineshere

Tried everything there already apart from the SETUP_CDROM thing. I doubt that will work though...

I get the "device is busy" error anytime I attempt to access my CD on NFS.
Using -r, -l, and if needed -f, one at a time and waiting a minute or so works sometimes, not always.
I take it that mounting floppies and other CDs works okay? If not I would check into disabling supermount.
Good Luck.

I've figured it out now.

Mandrake 9.0 automounts when you cd to /mnt/cdrom, so I never need to actuall mount the drive, jsut cd to it and ls. If I do mount it, it double mounts, because there's already a cdrom mount there. ;)

See, simple things cause the worst of problems...

Umm, that was mentioned explicitly in the link I posted. I had exactly the same thing happen w/ installing Unreal 2003.

I didn't realise that was the problem at the time, although it didn't say anything about automounting though...

Got a new problem now: NWN crashes when I click 'create new character'..

Great...

linux can be a bit<h cant it lol

That is it... :-/

*grumbles*

Beats Microshaft's Whinedoze any day though...

Note to self: Send email to WINE's developers to rename it to WHINE, because then they can say "If Windows starts causing you problems, then WHINE about it."
