一些版本信息：
Operating system is Ubuntu 11.10,on EC2,kernel is 3.0.0-16-virtual and the application info is: Version: 8.3.11 (api:88) GIT-hash: 0de839cee13a4160eed6037c4bddd066645e23c5 build by buildd@allspice,2011-07-05 19:51:07
在dmesg(见下文)中获得一些奇怪的错误,没有复制发生.我已将我的第一个节点设为主节点并显示：

我的辅助节点显示：

在奴隶上显示/ proc / drbd表明没有任何东西被转移……

}
我在主人身上运行了以下内容：
sudo drbdadm -- --overwrite-data-of-peer primary all
系统之间没有防火墙.
这是dmesg有一些错误：

编辑：
阅读其他一些类似的问题,有人建议做一个’drbdadm dump all’,所以我认为它不会受到伤害.
ubuntu@drbd01:~$drbdadm dump all
/etc/drbd.conf:19: in resource r0,on drbd01:
IP 23.XX.XX.XX not found on this host.
和奴隶：
root@drbd02:~# drbdadm dump all
/etc/drbd.conf:25: in resource r0,on drbd02:
IP 184.XX.XX.XX not found on this host.
奇怪的是它没有找到自己的ip,但是,这是一个使用弹性IP的Amazon EC2系统…这里是我的ipconfigs两者…

解决方法
你实际上不需要运行sudo drbdadm – –overwrite-data-of-peer primary all
只要/ dev / drbd您应该做到以下几点
Step01)sudo service MysqL在DRBD Primary上停止,因此不会为DRBD同步进行额外的更改
Step02)sudo drbdadm连接所有DRBD Secondary
Step03)DRBD Secondary上的sudo cat / proc / drbd以确保连接统计信息是WFConnection
Step04)sudo drbdadm连接所有DRBD Primary
步骤05)在DRBD主服务器上执行sudo cat / proc / drbd以确保连接状态为SyncTarget.
Step06)sudo服务MysqL停在DRBD主服务器上,所以MysqL可以恢复.同步将继续.您不必等待DRBD在步骤05中完全同步.
警告
不应在地理距离上使用DRBD.我使用通过CrossOver电缆通过192.168.x.x连接DRBD对的设置.
