Hi,
I've created a wrong storage from my disk and now I'm trying to create a directory storage. However, I can't do this because my disk got to the state when it's marked as "Device mapper". It has no partition or data or whatever. How can I create a directory from this disk?

Reinitialize it with GPT. If not possible via GUI use command line utility "parted".
