Cascading without fallback (CWOF) 是一个允许微调退回行为的级联资源组属性。当将 Cascading Without Fallback 标志设置为 False 时，则表示执行传统的级联资源组行为：当某个节点加入或重新集成到集群中时，如果其优先级比资源组当前所在的节点高，并且有接口可用，则资源组将退回到较高优先级的节点。当将此标志设置为 True 时，资源组不会退回到任何加入或重新集成到集群中的节点，即使该节点是较高优先级的节点。配置了 CWOF 的资源组不需要 IP 地址接管。
配置了 CWOF 的资源组不需要 IP 地址接管。各位大哥这个怎么理解！

看啥P中文翻译啊啊

Rotating groups share some similarities with Cascading without Fallback groups. However, there are important differences. Unlike cascading groups, rotating groups interact with one another. Because rotating resource groups require the use of IP address takeover, the nodes in the resource chain must all share the same network connection to the resource group. If several rotating groups share a network, only one of these resource groups can be up on a given node at any time. Thus, rotating groups distribute themselves. Cascading without Fallback groups, however, may “clump” together with multiple CWOF groups on the same node. CWOF does not require an IP address to be associated with the group.

CWOF does not require an IP address to be associated with the group.？就是这句话
！怎么理解！

Because rotating resource groups require the use of IP address takeover
CWOF does not require an IP address to be associated with the group
这两句无法理解。

意思是rotating resource group ip 接管的的方式只能是 ip replacement,？
所以If several rotating groups share a network, only one of these
resource groups can be up on a given node at any time

现在都不要管这些了，取消掉这些了

这些话是5.1上面光盘上面pdf文档的话！ 真是理解不进去啊！
