Run "fuser -vm /mnt/cdrom" (or wherever it's mounted) to find out what
processes are currently accessing (and therefore blocking) the device

To kill and restart NFS, run:

/etc/rc.d/init.d/<script that controls nfs on mandrake> stop
/etc/rc.d/init.d/<script that controls nfs on mandrake> start

Sorry I can't be more specific than that, I don't run Mandrake
but for example, under Debian 2.2 you would do
/etc/init.d/nfs-server stop
/etc/init.d/nfs-server start

(earlier versions of Debian have /etc/init.d/netstd-nfs instead)

If that doesn't work, kill the processes manually
(the ones that appear when you run the fuser command as above)
