Hi all

I am a Unix-newby and try to setup my WL-HDD using the guidance from
http://www.sprayfly.com/wiki/Filesystem

I fail mounting the partition to /opt
[admin@WL-HDD /]$ mount /dev/discs/disc0/part1 /opt
mount: Mounting /dev/discs/disc0/part1 on /opt failed: Invalid argument
[admin@WL-HDD /]$

In the guide is written:
now we will mount partition one to /opt . You may need to make this directory?

So I guess I need to make this directory first. But where and how?
I tried mkdir and got a directory but mounting did not work. Probably I need this directory on another place? Or do I have to set rights?

Thanks for a feedback, KaBuBu
