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.
