As you can see OST:0 is full!

Question1: Is any command to use in order to move arround 60% of OST:0 data 
from OST:0 to other OST or to all other OSTes (arround 20% to each other)?

Question2: How can i see larger objects (bigger then 100MB) stored on OST:0 
and correspondig files on /mnt/lustre? I want to erase them! lfs getstripe 
did not produce useful info!
