35# DESCRIPTION:
36#	"zfs snapshot -r" fails with invalid arguments or scenarios.
37#	The invalid scenarios may include:
38#	(1) The child filesystem already has snapshot with the same name
39#	(2) The child volume already has snapshot with the same name
40#
41# STRATEGY:
42#	1. Create an array of invalid arguments
43#	2. Execute 'zfs snapshot -r' with each argument in the array,
44#	3. Verify an error is returned.
