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