So if I don't want to or can't install DRBD 8.4 could I use two
resources to get around this multi-volume limitation in 8.3:

/etc/drbd.conf|:
resource r0 {
        protocol C;
        startup {
                wfc-timeout  15;
                degr-wfc-timeout 60;
        }
        net {
                cram-hmac-alg sha1;
                shared-secret "secret";
        }
        on drbd01 {
                device /dev/drbd0;
                disk /dev/sdb1;
                address 192.168.0.1:7788;
                meta-disk internal;
        }
        on drbd02 {
                device /dev/drbd0;
                disk /dev/sdb1;
                address 192.168.0.2:7788;
                meta-disk internal;
        }
}

resource r1 {
        protocol C;
        startup {
                wfc-timeout  15;
                degr-wfc-timeout 60;
        }
        net {
                cram-hmac-alg sha1;
                shared-secret "secret";
        }
        on drbd01 {
                device /dev/drbd1;
                disk /dev/sdb2;
                address 192.168.0.1:7788;
                meta-disk internal;
        }
        on drbd02 {
                device /dev/drbd1;
                disk /dev/sdb2;
                address 192.168.0.2:7788;
                meta-disk internal;
        }
}
