  32 # DESCRIPTION:
  33 #       ENOSPC is returned on pools with large physical block size and small
  34 #       recordsize.
  35 #
  36 # STRATEGY:
  37 #       1. Create a pool with property ashift=13 (8K block size)
  38 #       2. Set property recordsize=512 and copies=3 on the root dataset
  39 #       3. Write a file until the file system is full
  40 #       4. Verify the return code is ENOSPC
