  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.
