(使用11.10)社区AMI：ami-baba68d3
https://help.ubuntu.com/11.10/serverguide/C/drbd.html

启动过程时出现以下错误：

root@drbd01:~# sudo /etc/init.d/drbd start
 * Starting DRBD resources                                                                                            Can not load the drbd module.

创建了一个卷(在两个版本上)250gb卷,附加为/ dev / xvdm

这是我的配置文件：

global { usage-count no; }
common { syncer { rate 100M; } }
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 xvdm;
                address -MY AWS PUBLIC ELASTIC IP WAS HERE-:7788;
                meta-disk internal;
        }
        on drbd02 {
                device /dev/drbd0;
                disk /dev/xvdm;
                address -MY AWS PUBLIC ELASTIC IP WAS HERE-:7788;
                meta-disk internal;
        }
}
