36# DESCRIPTION:
37# A ZFS filesystem 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 the filesystem on mirror/raidz pool by writing a file until ENOSPC.
43# 2. Grow the mirror/raidz pool by adding another mirror/raidz vdev.
44# 3. Verify that more data can now be written to the filesystem.
