  35 # DESCRIPTION:
  36 # ENOSPC is returned on an attempt to write a second file
  37 # to a file system after a first file was written that terminated
  38 # with ENOSPC on a cleanly initialized file system.
  39 #
  40 # STRATEGY:
  41 # 1. Write a file until the file system is full.
  42 # 2. Ensure that ENOSPC is returned.
  43 # 3. Write a second file while the file system remains full.
  44 # 4. Verify the return code is ENOSPC.
