39#
40# DESCRIPTION:
41# A ZFS file system is limited by the amount of disk space
42# available to the pool. Growing the pool by adding a disk
43# increases the amount of space.
44#
45# STRATEGY:
46# 1) Fill a ZFS filesystem until ENOSPC by creating a large file
47# 2) Grow the pool by adding a disk
48# 3) Verify that more data can now be written to the file system
49#
50# TESTABILITY: explicit
51#
52# TEST_AUTOMATION_LEVEL: automated
53#
54# CODING_STATUS: COMPLETED (2005-07-04)
