39# DESCRIPTION:
40# Verify that many snapshots can be made on a zfs file system.
41#
42# STRATEGY:
43# 1) Create a files in the zfs file system
44# 2) Create a snapshot of the dataset
45# 3) Remove all the files from the original file system
46# 4) Verify consistency of each snapshot directory
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2005-07-04)
