Thanks for your reply.
As my other lab is currently occupied with some test systems running for my academic studies, I'm setting up a "new" lab (again with tiered storage spaces) to test that behavior again.
Student -> Limited Budget -> old hardware.
I've got 2 Supermicro X7DB8 Boards, 4x Xeon E5420, 2x 8 GB DDR2-ECC RAM and 2x Brocade 1020 to play with.
I also got enough hdds to build 2 storage spaces, but in order to build the same storage space again... I also need 2 SSDs.
And I need to save more money to buy them... Maybe in 2-4 weeks...

Thats how it looks like right now:

I'll keep you updated as soon as I got this lab together.
