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