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
