  37 # DESCRIPTION:
  38 # After vdev expansion, all 4 labels have the same set of uberblocks.
  39 #
  40 #
  41 # STRATEGY:
  42 # 1) Create 3 files
  43 # 2) Create a pool backed by the files
  44 # 3) Expand the files' size with truncate
  45 # 4) Use zpool online -e to expand the vdevs
  46 # 5) Check that for all the devices, all 4 labels have the same uberblocks
