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#
