> Hi
> 
We have just installed SuSe Linux 7.0 and are now experoience the following
problem.
Is there anybody who has an idea to solve the problem.
> We mount a cdrom in one host under directory /cdrom then we mount
> that directory from another host (host2). We then unmount that directory 
> in host2 but when we try to unmount the /cdrom in host1 we get 
> "/cdrom: device is busy" and have to restart host1 to relese the CD.
