问题描述

通过AIQUM 和命令行界面可以看到高延迟

AIQUM 显示卷延迟较高。

CLI 显示中的高延迟 Network

EMS事件，用于 fpolicy.server.connectError 声明 TCP Connection to the FPolicy server failed：

Wed Dec 01 13:37:32 +0800 [cluster_n01: fpolicy: fpolicy.server.connectError:error]: Node failed to establish a connection with the FPolicy server "xx.xx.xx.xx" (reason: "TCP Connection to FPolicy server failed.").

禁用Fpolicy延迟恢复为预期值。
