35# DESCRIPTION:
36# 'zpool add [-f]' can add large numbers of file-in-zfs-filesystem-based vdevs
37# to the specified pool without any errors.
38#
39# STRATEGY:
40# 1. Create assigned number of files in ZFS filesystem as vdevs and use the first
41# file to create a pool
42# 2. Add other vdevs to the pool should get success
43# 3  Fill in the filesystem and create a partially written file
44# as vdev
45# 4. Add the new file into the pool should be failed.
46#
47# TESTABILITY: explicit
48#
49# TEST_AUTOMATION_LEVEL: automated
50#
51# CODING_STATUS: COMPLETED (2005-10-09)
