[HPDD-discuss] mv on the same file system does copy

I am trying to move some large directories on the same lustre filesystem however I can see that instead of quick name remapping mv does copy operation. Is there a way to avoid this? As a test I created new directory with hundreds of large files and moved it and mv works as expected. I do not understand what is different about the other directories that they can not be simply moved.
