35# DESCRIPTION:
36# Tests file truncation within ZFS while a sync operation is in progress.
37#
38# STRATEGY:
39# 1. Copy a file to ZFS filesystem
40# 2. Copy /dev/null to same file on ZFS filesystem
41# 3. Execute a sync command
42#
43# TESTABILITY: explicit
44#
45# TEST_AUTOMATION_LEVEL: automated
46#
47# CODING_STATUS: COMPLETED (2005-07-04)
