direct links of old sources may well be a few messages off.

Both nodes:

resource r0 {
        meta-disk internal;
        device /dev/drbd0;
        on NodeA {
	        disk /dev/vg01/share;
                address 2.2.2.150:7788;
        }
        on NodeB {
	        disk /dev/vg02/share;
		address 2.2.2.151:7788;
        }
}

It's OK for your nodes to be different, but *do include that in your
config*. Save yourself from pain down the road.
