# ID: zvol_swap_004_pos
#
# DESCRIPTION:
#	The minimum volume size for swap should be a multiple of 2 pagesize
#	bytes.
#
# STRATEGY:
#	1. Get test system page size.
#	2. Create different size volumes.
#	3. Verify 'swap -a' has correct behaviour.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-12-12)
