43# DESCRIPTION:
44#	System with compressed_arc disabled succeeds at reading from L2ARC
45#
46# STRATEGY:
47#	1. Enable compressed_arc.
48#	2. Create pool with a cache device, encryption, and compression enabled.
49#	3. Read the number of L2ARC checksum failures.
50#	4. Create a random file in that pool and random read for 30 sec.
51#	5. Read the number of L2ARC checksum failures.
