35# DESCRIPTION:
36# A ZFS filesystem is limited by the amount of disk space
37# available to the pool. Growing the pool by adding a disk
38# increases the amount of space.
39#
40# STRATEGY:
41# 1. Fill the filesystem on mirror/raidz pool by writing a file until ENOSPC.
42# 2. Grow the mirror/raidz pool by adding another mirror/raidz vdev.
43# 3. Verify that more data can now be written to the filesystem.
