40# DESCRIPTION:
41# Tests file truncation within ZFS while a sync operation is in progress.
42#
43# STRATEGY:
44# 1. Copy a file to ZFS filesystem
45# 2. Copy /dev/null to same file on ZFS filesystem
46# 3. Execute a sync command
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2005-07-04)
