无法启动drbd服务，并且无法在CentOS 7.3上设置DRBD 8.4的主节点

使用两个节点来安装DRBD。

节点1
节点2

遵循这个指南：

http://www.learnitguide.net/2016/07/how-to-install-and-configure-drbd-on-linux.html

在两个节点上

resource testdata1 { protocol C; on node1 { device /dev/drbd0; disk /dev/sdb; address 192.168.0.1:7788; meta-disk internal; } on node2 { device /dev/drbd0; disk /dev/sdb; address 192.168.0.2:7788; meta-disk internal; } }

在node2上

在运行systemctl start drbd ，进程有待处理。等待很长时间没有结果。但是node1在这一步运行良好。

在node1上

运行drbdadm primary testdata1 ，得到这个错误：

 0: Failure: (127) Device minor not allocated additional info from kernel: unknown minor Command 'drbdsetup-84 primary 0' terminated with exit code 10

编辑

在node2上运行`systemctl status drbd`

DRBD目前没有连接到其同行。这清楚地显示在连接状态字段下的/proc/drbd ： cs:WFConnection

此外，磁盘状态字段中显示的磁盘状态报告为“不一致”： ds:Inconsistent/DUnknown

您将需要确定为什么他们没有连接，让他们连接，然后您将需要完成初步同步，如DRBD用户指南中所述： https : //docs.linbit.com/doc/users-guide- 84 / S-初始全同步/
