问题描述

  • 数据包跟踪显示了 节点管理LIF生成的一系列PTR请求 、用于反向查找 集群LIF的IP (11.22.33.44):
    1 <node management IP> 50445      <DNS IP>                domain    DNS   Standard Query 0xdf71 PTR 44.33.22.11.in-addr.arpa2 <DNS IP> domain                  <node management IP>    50445 DNS Standard Query        Response 0xdf71
    无此名称PTR 44.33.22.11.in-addr.arpa soa localhost

  • 随着DNS风暴、DNS服务器可能会停止回答集群SVM中的问题、从而导致dns.server.timed.out错误
    mgwd:dns.server.timed.out:error]: DNS服务器111.111.11未在超时时间间隔内响应SVM = SVM。 mgwd:dns.server.timed.out:error]: DNS服务器111.111.1.12未在超时时间间隔内响应SVM = SVM。
     

  • 审核日志包含/API/privacy/CLI/network/Connections /active的REST请求 、其中请求了REMOVERE_HOST字段
