你好,

我正在一个地堡环境中为客户实现Nutanix AHV。没有internet访问，并且基础设施在集群基础设施之外只有很少或没有LAN通信。

客户希望使用基于hosts文件的IP和射击名，而不是DNS解析。不幸的是，在Foundation上，没有办法在没有DNS的情况下设置集群。我想NTP也是一样的，但我没有做到。

有解决方案吗?或者NTP和DNS是集群工作的必选项?

    \nI'm implementing Nutanix AHV at a customer in a bunker environment. There is no internet access, and the infrastructure will have minimal to no LAN communication outside of the cluster infrastructure.
    \n
    \nThe customer expected to use IP and shot names based on hosts files instead of DNS resolution. Unfortunately, on Foundation, there is no way to setup the cluster with no DNS. And I guess NTP will be the same, but I didn't get there.
    \n
    \nAny workaround ? Or are NTP and DNS mandatory for the cluster to work ?","quoteUsername":"Gandahar","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    只需输入一些垃圾值，然后销毁它，也许只是将它作为一个“占位符”指向默认网关。

    你可以不用它。

    也就是说，如果有可能的话，NTP会很好

    你好乔恩,
    我有同样的问题:没有DNS和NTP, nutanix能很好地工作吗?
    因为NCC检查报告一个错误"FAIL: Unable to get configured fqdn for host: "
    我在ESXI CLI中尝试解析ip到domainname失败。但可以解析名称到ip。
    用户告诉我他们不允许DNS反向解析。

    但是NCC每次运行时都会报告错误。
    我可以忽略这个吗?

    \nI have the same question: Can nutanix works well without DNS and NTP ?
    \nbecause NCC check reports an error \"FAIL: Unable to get configured fqdn for host: \"
    \nand I tried resolve ip to domainname failed in ESXI CLI. but can resolve name to ip.
    \nthe user told me they did`t allow dns reverse resolution.
    \n
    \nBut NCC reports error everytime running it.
    \nCan I ignore this ?","quoteUsername":"xiaowei","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    哪个版本的NCC / AOS失败了?你有什么配置?

    你好乔恩,
    《超能4.6.1.1
    NCC与AOS4.6.1捆绑在一起
    用户现场有DNS服务器，但DNS服务器只支持正向解析，不支持反向解析。NCC检查报告这是一个错误。
    所以我想确认一下我是否可以忽略这个错误，并可能屏蔽NCC DNS检查脚本。

    如果其他用户甚至没有DNS服务器，nutanix可以工作，需要特殊的配置?
    Nutanix-NPP | NetApp-NCDA NCIE |@jolinvsshane
    \nAOS 4.6.1.1
    \nNCC is bundled with AOS4.6.1
    \nThe user has DNS server onsite,but DNS server supports only forward lookup and deny reverse resolution. and NCC check reports it as an error.
    \nSo I`d like to confirm if I can ignore the error, and maybe mask NCC DNS check script.
    \n
    \nalso if other users even doesn`t have a DNS server, Can nutanix works ,need special configuration ?","quoteUsername":"xiaowei","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    这个配置很好，但运行状况检查不考虑这种情况。
