rsync(1) and mount(8) are designed to work with filesystems, not partitions.


Assuming your script goes one-by-one through the filesystems, perhaps a 
newly mounted filesystem is not quite ready when rsync(1) is invoked.  I 
would try adding a time delay (e.g. 'sleep 10') before invoking rsync(1).
