#
# DESCRIPTION:
# 'zpool add [-f]' can add large numbers of file-in-zfs-filesystem-based vdevs
# to the specified pool without any errors.
#
# STRATEGY:
# 1. Create assigned number of files in ZFS filesystem as vdevs and use the first
# file to create a pool
# 2. Add other vdevs to the pool should get success
# 3  Fill in the filesystem and create a partially written file
# as vdev
# 4. Add the new file into the pool should be failed.
