Free space problem

Hi there,

i installed proxmox on a ssd raid (raid1). Then i installed 2 HDD's as raid 1. I unmount var/lib/vz on the ssd and changed it to a new lvm ext3 space of the hdd's.
After that, i see in df -h that i have 930GB total space, and 450 mb used space (iso's etc.). But in the webinterface, there it shows 45GB total used space . What's wrong?

Best regards
