  37 # DESCRIPTION:
  38 # After zpool online -e poolname zvol vdevs, zpool can autoexpand by
  39 # Dynamic LUN Expansion
  40 #
  41 #
  42 # STRATEGY:
  43 # 1) Create 3 files
  44 # 2) Create a pool backed by the files
  45 # 3) Expand the files' size with truncate
  46 # 4) Use zpool reopen to check the expandsize
  47 # 5) Use zpool online -e to online the vdevs
  48 # 6) Check that the pool size was expanded
