From a file system level lustre is not aware of any blocks, it just
deals at object level ! So no there is no block level locking.
On second question it depends how big your block can be,
realistically no because the object has to be in a size that is a
multiple of (few kilobytes i think 64k i am not sure about the number).

Two more question:
Does lustre support block level locking also?
Can the objects on OST be as small as a single block

Lustre supports object level striping across OST's, each OST could
consist of a RAID device that would in turn do the block level
striping across multiple disks.

Since generally the devices used to store the data are block level
devices (and not object disks) the objects on OST are at the lowest
level stored as blocks.
