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
