34# DESCRIPTION:
35# ENOSPC is returned on an attempt to write a second file
36# to a file system after a first file was written that terminated
37# with ENOSPC on a cleanly initialized file system.
38#
39# STRATEGY:
40# 1. Write a file until the file system is full.
41# 2. Ensure that ENOSPC is returned.
42# 3. Write a second file while the file system remains full.
43# 4. Verify the return code is ENOSPC.
44#
45# TESTABILITY: explicit
46#
47# TEST_AUTOMATION_LEVEL: automated
48#
49# CODING_STATUS: COMPLETED (2005-07-04)
