35# DESCRIPTION:
36# Create as many directories with 50 big files each until the file system
37# is full. The zfs file system should be stable and works well.
38#
39# STRATEGY:
40# 1. Create a pool & dateset
41# 2. Make directories in the zfs file system
42# 3. Create 50 big files in each directories
43# 4. Test case exit when the disk is full.
44#
45# TESTABILITY: explicit
46#
47# TEST_AUTOMATION_LEVEL: automated
