/dev/mapper/pve-root used 100%

I have a really strange problem here.
One of my promox installations (no cluster, just a single node), has no more disk space left in the root partition.
I did several checks and also asked my colleague about this, but I can't find where the diskpace has gone to.
Here is my output of df -h:

Filesystem            Size  Used Avail Use% Mounted on
udev                   10M     0   10M   0% /dev
tmpfs                  12G  416K   12G   1% /run
/dev/mapper/pve-root   69G   69G     0 100% /
tmpfs                 5.0M     0  5.0M   0% /run/lock
tmpfs                  23G   19M   23G   1% /run/shm
/dev/mapper/pve-data  156G  3.8G  152G   3% /var/lib/vz
/dev/sda1             496M   82M  389M  18% /boot
/dev/fuse              30M   16K   30M   1% /etc/pve
/dev/sdc1             4.0T  3.8T   35G 100% /iSCSI_backup_volume

Thank you in advance for your help.

I think I now what the problem is, but I can't fix it.
Somehow, proxmox mounted my iSCSI volume directly into /.
Even when I detach my iSCSI target in the GUI, the /iSCSI_backup_volume folder is still accessible via console.

Any ideas are highly appreciated.
