# DESCRIPTION:
#       Verify that 'zfs mount -a' succeeds as root.
#
# STRATEGY:
#       1. Create a group of pools with specified vdev.
#       2. Create zfs filesystems within the given pools.
#       3. Unmount all the filesystems.
#       4. Verify that 'zfs mount -a' command succeed,
#	   and all available ZFS filesystems are mounted.
#	5. Verify that 'zfs mount' is identical with 'df -F zfs'
#
