食人鱼/脉冲，lvs.cf与持久性和服务器故障

我们有以下设置：

• RedHat 6
• LVS设置为在两个Web服务器之间失败
• 连接持续900秒

这是一个非常简单的设置，但是当一台服务器被标记为失败时，piranha / pulse / nanny进程将表中服务器的权重标记为0，并且不会删除发生故障的服务器。 这意味着任何持久性连接都会保留连接到发生故障的服务器，并且负载平衡将被打败。

我们怎么能告诉保姆强制失败的节点，所以持久连接失败的工作节点？

谢谢

• 在Ec2 RedHat上找不到mkgroup命令？
• yum更新没有任何更新？
• 在RHEL 6.6上用yum升级libcurl时出错
• 更新clamav-milter后，ClamAV Milter服务将无法启动
• RHEL5 64位相当于ia32-libs？

我们有以下lvs.cf：
