34# DESCRIPTION:
35# Verify that many snapshots can be made on a zfs dataset.
36#
37# STRATEGY:
38# 1) Create a file in the zfs dataset
39# 2) Create a snapshot of the dataset
40# 3) Remove all the files from the original dataset
41# 4) For each snapshot directory verify consistency
42#
43# TESTABILITY: explicit
44#
45# TEST_AUTOMATION_LEVEL: automated
46#
47# CODING_STATUS: COMPLETED (2005-07-04)
