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