Something is wrong with your /dev/sda3. Lustre is not finding a proper 
block device there, so it assumes you are using a loopback device, but
since you are not using a loopback, it fails (size is only used with 
loopback)  Verfiy that sda exists, and is partitioned correctly. (sda3 
exists)
As a test, make an ext2 FS on sda3 with mkfs. If that works, Lustre 
should work fine.
