40 # DESCRIPTION:
41 # ZFS will not interfere with devices that are in use by ufsdump or
42 # ufsrestore.
43 #
44 # STRATEGY:
45 # 1. newfs a disk
46 # 2. mount the disk
47 # 3. create files and dirs on disk
48 # 4. umount the disk
49 # 5. ufsdump this disk to a backup disk
50 # 6. Try to create a ZFS pool with same disk (also as a spare device)
51 # 7. ufsrestore the disk from backup
52 # 8. try to create a zpool during the ufsrestore
53 #
