Access to partition on SD card (Raspberry Pi)

I have downloaded the raspberry pi image and burned it to my 8BG SD card, and it is working fine.

I then followed the descriptions in the link below and used fdisk to make a new patition(~4GB) on the sd card and formated it with ext4, and mounted it under /mnt/

I then expected it to show up in the webGUI so i could setup FTP and AFP access to the drive/partition, but it did not show up. What did I do wrong? Do i need to mount it elsewhere?

Thanks

Really? Why is that?

My plan was to have the data on an other partition, and then I gould always flash the rootfs and keep the data.

I guess there must be a way to make the system think the extra partition is a physical drive,and then mount it...

Ahh I see. Didn't know that. Thanks

At the moment I'm testing on a RPi model A so I only have one USB port with a ethernet card attached, so I need to find a USB hub or an other RPi with more USB ports.

"The problem is that OpenMediaVault may not recognize the name of the sd card correctly"
Are there any way I can begin testing with data on the SD card or is it not possible at all? A pointer in some direction would be great.

Thanks for taking you time to answer my annoying questions
