If you delete a file, and space does not get freed, it's usually either
because the file is still kept open, or there are other hardlinks to it.

Can you run: 
lsof | grep deleted

Title:
  Directory size grows when creating/deleting thousands of files

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Run the attached bash script. ( it might cause wear and tear on your
  hard drive ).

  What I expect should happen :

  Folder size of test should be 4.0K like before I ran the test.

  What actually happened :

  Folder size is not 2.1M ( 2138112 bytes ).

  There does not seem to be any way to recover the 2 megabytes lost and
  the only way to get the folder size back to 4.0K is to delete it and
  recreate it.
