36# DESCRIPTION:
37# Turning disks in a pool offline should fail when there is no longer
38# sufficient redundancy.
39#
40# STRATEGY:
41# 1. Start some random I/O on the mirror or raidz.
42# 2. Verify that we can offline as many disks as the redundancy level
43# will support, but not more.
44# 3. Verify the integrity of the file system and the resilvering.
