drbd无法启动无法加载drbd模块

我正在尝试在虚拟机上使用 centoOS 6.3 学习 drbd，我配置了两个虚拟机，节点 1 是原始的，节点 2 是从节点 1 克隆的，但我无法启动“service drbd start”，出现错误消息“启动 DRBD 资源：无法加载 drbd 模块”，而节点 2 可以启动该命令，这是配置

[root@localhost db]# cat /etc/drbd.conf

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

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

    global {
        # do not participate in online usage survey
        usage-count no;
    }

    resource data {

        # write IO is reported as completed if it has reached both local
        # and remote disk
        protocol C;

        net {
            # set up peer authentication
            cram-hmac-alg sha1;
            shared-secret "s3cr3tp@ss";
            # default value 32 - increase as required
            max-buffers 512;
            # highest number of data blocks between two write barriers
            max-epoch-size 512;
            # size of the TCP socket send buffer - can tweak or set to 0 to
            # allow kernel to autotune
            sndbuf-size 0;
        }

        startup {
            # wait for connection timeout - boot process blocked
            # until DRBD resources are connected
            wfc-timeout 30;
            # WFC timeout if peer was outdated
            outdated-wfc-timeout 20;
            # WFC timeout if this node was in a degraded cluster (i.e. only had one
            # node left)
            degr-wfc-timeout 30;
        }

        disk {
            # the next two are for safety - detach on I/O error
            # and set up fencing - resource-only will attempt to
            # reach the other node and fence via the fence-peer
            # handler

            # resync-rate 10M;
        }
        handlers {

        on node1.mycluster.org {
            # DRBD device
            device /dev/drbd0;
            # backing store device
            disk /dev/sdb;
            # IP address of node, and port to listen on
            address 192.168.1.101:7789;
            # use internal meta data (don't create a filesystem before
            # you create metadata!)
            meta-disk internal;
        }
        # second node
        on node2.mycluster.org {
            # DRBD debice
            device /dev/drbd0;
            # backing store device
            disk /dev/sdb;
            # IP address of node, and port to listen on
            address 192.168.1.102:7789;
            # use internal meta data (don't create a filesystem before
            # you create metadata!)
            meta-disk internal;
        }
    }

有人知道这是什么问题吗？

这听起来不像是配置问题 - 而更像是没有安装 DRBD 的内核模块。您需要安装适当版本的 kmod-drbd。（如果您输入 modprobe drbd 会发生什么？）

从命令行尝试执行 yum search drbd

然后选择正确的包 - 可能是 kmod-drbd83

如果这不起作用，也许可以升级到较新版本的 CentOS 和内核。
