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 mirror/raidz until ENOSPC by creating lots
47# of files
48# 2) Grow the mirror/raidz by adding a disk
49# 3) Verify that more data can now be written to the file system
50#
51# TESTABILITY: explicit
52#
53# TEST_AUTOMATION_LEVEL: automated
54#
55# CODING_STATUS: COMPLETED (2005-10-04)
