the weight should be the size of the filesystem. With weight 1 for all
disks, you run in trouble if your cluster filled, because the 1TB-Disks
are full, before the 3TB disk!

You should have something like 0.9 for the 1TB and 2.82 for the 3TB
disks ( "df -k | grep osd | awk '{print $2/(1024^3) }' " ).
