commit 90ecab35525ea3637a59763d75df6712ff91728a

    Expand HAMMER filesystem step 1/2
    
    Format the volume and increase other volumes' vol_count field.
    The space of the new volume is not yet given to the filesystem (that's step 2).
    
    Example:
    
    	newfs_hammer -L TEST /dev/da0
    	mount_hammer /dev/da0 /hammer
    	hammer expand /hammer /dev/da1
    	umount /hammer
    	mount_hammer /dev/da0:/dev/da1 /hammer
    
    	# the following fails (wrong number of volumes)
    	mount_hammer /dev/da0 /hammer
