37#
38# DESCRIPTION:
39# A ZFS file system is limited by the amount of disk space
40# available to the pool. Growing the pool by adding a disk
41# increases the amount of space.
42#
43# STRATEGY:
44# 1) Fill a ZFS filesystem until ENOSPC by creating a large file
45# 2) Grow the pool by adding a disk
46# 3) Verify that more data can now be written to the file system
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2005-07-04)
