36# DESCRIPTION:
37# ZFS will not interfere with devices that are in use by ufsdump or
38# ufsrestore.
39#
40# STRATEGY:
41# 1. newfs a disk
42# 2. mount the disk
43# 3. create files and dirs on disk
44# 4. umount the disk
45# 5. ufsdump this disk to a backup disk
46# 6. Try to create a ZFS pool with same disk (also as a spare device)
47# 7. ufsrestore the disk from backup
48# 8. try to create a zpool during the ufsrestore
49#
