# ID: zfs_unmount_all_001_pos
#
# DESCRIPTION:
#       Verify that 'zfs unmount -a[f]' succeeds as root.
#
# STRATEGY:
#       1. Create a group of pools with specified vdev.
#       2. Create zfs filesystems within the given pools.
#       3. Mount all the filesystems.
#       4. Verify that 'zfs unmount -a[f]' command succeed,
#	   and all available ZFS filesystems are unmounted.
#	5. Verify that 'zfs mount' is identical with 'df -F zfs'
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-12)
