  37 # DESCRIPTION:
  38 # Once zpool set autoexpand=on poolname, zpool can autoexpand by
  39 # Dynamic VDEV Expansion
  40 #
  41 #
  42 # STRATEGY:
  43 # 1) Create three vdevs (loopback, scsi_debug, and file)
  44 # 2) Create pool by using the different devices and set autoexpand=on
  45 # 3) Expand each device as appropriate
  46 # 4) Check that the pool size was expanded
  47 #
  48 # NOTE: Three different device types are used in this test to verify
  49 # expansion of non-partitioned block devices (loopback), partitioned
  50 # block devices (scsi_debug), and non-disk file vdevs.  ZFS volumes
  51 # are not used in order to avoid a possible lock inversion when
  52 # layering pools on zvols.
