  21 # DESCRIPTION:
  22 # 'zpool split' should fail if resilver in progress for a disk
  23 #
  24 # STRATEGY:
  25 # The first scenario:
  26 # 1. Create a mirror pool
  27 # 2. Offline the first VDEV
  28 # 3. Put some data
  29 # 4. Online the first VDEV
  30 # 5. Verify 'zpool split' must fail
  31 #
  32 # The second scenario:
  33 # 1. Create a mirror pool
  34 # 2. Offline the second VDEV
  35 # 3. Put some data
  36 # 4. Online the second VDEV
  37 # 5. Verify 'zpool split' must fail
