36# DESCRIPTION:
37# A ZFS file system is limited by the amount of disk space
38# available to the pool. Growing the pool by adding a disk
39# increases the amount of space.
40#
41# STRATEGY:
42# 1) Fill a ZFS filesystem until ENOSPC by creating a large file
43# 2) Grow the pool by adding a disk
44# 3) Verify that more data can now be written to the file system
45#
