For the first question the answer is no

I will do it at the evening.

I have installed The pie new and direct after that I was not able to configuration the driver

First I installed wheeze as OS then I update the PI with sudo apt-get update and upgrade, then I installed the new kernel after that I changed the Port for SSH and the username for PI then activate IPv6 after that I installed omv.

I installed the PI and after I find the error I was use google but I find nothing then I was write here

For better understanding you mean that I unmount the drive over the PI desktop and then I must mount it over the (my own) omw web page

Okay it's done now, I have do this over SSH

sudo umount /dev/sdb1
sudo umount /dev/sda1

so I unmount my 2 driver after that I mount them vs OMV and it looks like that it works now, thanks to subzero79 for your help

It works now thank you for your help
