Checking O2CB heartbeat: Not active 原因

[root@ecsrac01 ocfs2]#
[root@ecsrac01 ocfs2]# /etc/init.d/o2cb  configure
Configuring the O2CB driver.

This will configure the on-boot properties of the O2CB driver.
The following questions will determine whether the driver is loaded on
boot.  The current values will be shown in brackets ('[]').  Hitting
without typing an answer will keep that current value.  Ctrl-C
will abort.

Load O2CB driver on boot (y/n) [y]: y
Cluster to start on boot (Enter "none" to clear) [ocfs2]:
Specify heartbeat dead threshold (>=7) [31]: 61
Specify network idle timeout in ms (>=5000) [30000]:
Specify network keepalive delay in ms (>=1000) [2000]:
Specify network reconnect delay in ms (>=2000) [2000]:

Checking O2CB heartbeat: Not active

 

Checking O2CB heartbeat: Not active                     在格式化和挂载文件系统之前，应验证 O2CB 在两个节点上均联机；O2CB 心跳当前没有活动，因为文件系统还没有挂载 。挂载之后就会变成active  .
