OCFS 配置

我正在设置虚拟机，并尝试让 OCFS 允许跨两个设备冗余。配置似乎可以正常工作，但实际上并没有同步文件：

/etc/ocfs2/cluster.conf

cluster:
        node_count = 2
        name = vmcluster

node:
        ip_port = 7777
        ip_address = 198.18.0.25
        number = 1
        name = vm1
        cluster = vmcluster

node:
        ip_port = 7777
        ip_address = 198.18.0.26
        number = 2
        name = vm2
        cluster = vmcluster

/etc/sysconfig/o2cb

# O2CB_ENABLED: 'true' means to load the driver on boot.
O2CB_ENABLED=true

# O2CB_STACK: The name of the cluster stack backing O2CB.
O2CB_STACK=o2cb

# O2CB_BOOTCLUSTER: If not empty, the name of a cluster to start.
O2CB_BOOTCLUSTER=vmcluster

# O2CB_HEARTBEAT_THRESHOLD: Iterations before a node is considered dead.
O2CB_HEARTBEAT_THRESHOLD=

# O2CB_IDLE_TIMEOUT_MS: Time in ms before a network connection is considered dead.
O2CB_IDLE_TIMEOUT_MS=

# O2CB_KEEPALIVE_DELAY_MS: Max time in ms before a keepalive packet is sent
O2CB_KEEPALIVE_DELAY_MS=

# O2CB_RECONNECT_DELAY_MS: Min time in ms between connection attempts
O2CB_RECONNECT_DELAY_MS=

OCFS 程序的状态：

[root@vm1 ~]# /etc/init.d/ocfs2 status
Configured OCFS2 mountpoints:  /cluster1 /cluster2
Active OCFS2 mountpoints:  /cluster1 /cluster2

[root@vm1 ~]# /etc/init.d/o2cb status

我看到心跳模式显示“本地”。我查阅了以下文档：http://oss.oracle.com/projects/ocfs2/dist/documentation/v1.6/ocfs2-1_6-usersguide.pdf以及旧教程http://www.hbyconsultancy.com/blog/shared-ocfs2-partition-on-ubuntu-server-10-04-x64.html和其他地方。我似乎没有看到全貌……

我正在使用 Oracle Linux 3.0.1，它是 RHEL6 的修改版本。

最好将其保留为注释，但我没有选择。无论如何，关于您的 ocfs2 配置文件，节点编号从 0 开始，而不是 1；因此您将拥有节点 0 和 1，而不是 1 和 2。我不能说这会解决您的问题，但无论如何......
