linux - 为什么在 CentOS 7 上无法为 DRBD 创建资源？

Question

按照本指南在 CentOS 7.3 上安装 DRBD:

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

执行此步骤后:

resource testdata1 {
protocol C;           
on node1 {
        device /dev/drbd0;
        disk /dev/sdb;
        address 172.16.2.61:7788;
        meta-disk internal;
    }
    on node2 {
        device /dev/drbd0;
        disk /dev/sdb;
        address 172.16.2.62:7788;
        meta-disk internal;
    }
} 

运行时:

drbdadm create-md testdata1

收到消息:

'testdata1' not defined in your config (for this host).

/etc/hosts 是:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

172.16.2.61              node1.clusterbr.int   node1
172.16.2.62              node2.clusterbr.int   node2
172.16.2.60              dbip.clusterbr.int   node1

/etc/drbd.conf 配置是:

# You can find an example in  /usr/share/doc/drbd.../drbd.conf.example

include "drbd.d/global_common.conf";
include "drbd.d/*.res";

问题的原因是什么？

Answer 1

原因是没有在 drbd 配置文件中设置正确的主机名。

使用uname -a可以看到主机名。将其设置为配置。
