38# DESCRIPTION:
39# Create as many directories with 50 big files each until the file system
40# is full. The zfs file system should be stable and works well.
41#
42# STRATEGY:
43# 1. Create a pool & dateset
44# 2. Make directories in the zfs file system
45# 3. Create 50 big files in each directories
46# 4. Test case exit when the disk is full.
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
