  31 # DESCRIPTION:
  32 # 'zpool add [-f]' can add large numbers of file-in-zfs-filesystem-based vdevs
  33 # to the specified pool without any errors.
  34 #
  35 # STRATEGY:
  36 # 1. Create assigned number of files in ZFS filesystem as vdevs and use the first
  37 # file to create a pool
  38 # 2. Add other vdevs to the pool should get success
  39 # 3  Fill in the filesystem and create a partially written file
  40 # as vdev
  41 # 4. Add the new file into the pool should be failed.
